Photograph by James Castner, University of Florida. Tropical diseases of legumes. Nymphs are flattened and oval in shape, greenish-yellow in color, and range from 0.365 mm (second instar) to 0.662 mm (fourth instar) in length. feeding on Bemisia nymphs (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Bemisia has arrhenotokous parthenogenetic reproduction where virgin females can only lay haploid eggs which give rise to males. and are available for field and greenhouse application against Bemisia. Figure 13. Like other species of platystomatid nics, … The crawler has three pairs of well-developed four-segmented legs, three-segmented antennae, and small eyes. Various nymphal instars of Bemisia. The immature parasitoids develop within the whitefly host, eventually consuming the entire host, except the integument. It was found attacking crops that it had not infested previously, such as poinsettia, and was resistant to many formerly effective insecticides. It transmitted new plant-pathogenic viruses that had never affected cultivated crops and induced plant physiological disorders, such as tomato irregular ripening and squash silverleaf disorder. 1997. There is usually a pre-oviposition period of less than a day to a few days, depending on the temperature. Common Name: Sweetpotato Whitefly Scientific Name: Bemisia tabaci Order and Family: Hemiptera, Aleyrodidae Size and Appearance: Length (mm) Appearance Egg 0.21 x … In these situations, natural biological control keeps Bemisia below economically injurious levels. Figure 9. Evans GA, Hamon AB.  CLASS: Insecta Adult bigeyed bug (Geocoris sp.) Photograph by Scott Bauer, USDA. plant. Colored plastic mulches may be effective in reducing whitefly populations and geminivirus incidence. American Samoa, Australia, Cook Islands, Fiji, Fremch Polynesia, Guam, Kiribati, Marshall Islands, Nauru, New Caledonia, Northern Marianas Islands, Palau, Papua New Guinea, Samoa, Solomon Islands, Tokelau, Tonga, and Vanuatu. Its hosts include vegetable, field, and ornamental crops. Glossy (less waxy) crucifers, such as broccoli and collard, are less acceptable for oviposition than are varieties with a normal wax layer. Searching and feeding behavior of. Gerling D. Glycine max. In Costa Rica, living mulches (e.g., perennial peanut and cilantro) may reduce somewhat the spread of geminivirus within tomato fields. Figure 21. 'Florida Lanai' cherry tomato showing external symptoms of Bemisia-induced tomato irregular ripening disorder (left) and control fruit from uninfested plant (right) (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). The sweetpotato whitefly, Bemisia tabaci (Gennadius), has been recorded in the United States since the late 1800s. Greenhouses are screened with very fine mesh plastic screen. All rights reserved. Exuvia of Bemisia with characteristic T-shaped whitefly adult emergence slit (left), and exuvia of Bemisia with round emergence hole through which an adult parasitoid emerged (right). Figure 7. March 06, 2013. (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Before 1986, it was only an occasional pest of cultivated crops. Several effective species of parasitoids, such as Eretmocerus eremicus, and predators, such as lacewings and the coccinellid Delphastus catalinae, are available commercially for control of Bemisia.

Name Language cassava whitefly English cotton whitefly English silver-leaf whitefly English sweet-potato whitefly English tobacco whitefly English Baumwollmottenschildlaus German Tabakmottenschildlaus German weiße Fliege This whitefly was thought to be a new biotype of Bemisia tabaci (designated variously as B biotype, Florida biotype, or poinsettia biotype), possibly introduced from the Middle East. Photograph by James Castner, University of Florida. It is found throughout the southern United States and can overwinter outdoors as far north as South Carolina. Photograph by Heather McAuslane, University of Florida. Figure 12. Minnesota. Photograph by Shahab Hanif-khan, University of Florida. Its common name is the silverleaf whitefly, because of its unique ability to induced silverleaf disorder in squash. Some well-known generalist predators that prey on whiteflies include Chrysoperla species larvae (lacewings), Orius species (minute pirate bugs), and Geocoris species (bigeyed bugs). Trialeurodes vaporariorum (Westwood) Beauveria bassiana and Verticillium lecanii, two fungal pathogens with efficacy against Bemisia and other insects, have been commercialized Adult minute pirate bug (Orius sp.) Photograph by Kim Hoelmer, USDA. Israeli researchers have had success with the use of barriers to keep viruliferous Bemisia from invading greenhouses. It quickly moved into other southern states with intensive agricultural and horticultural industries (Texas, Arizona, and California), and displaced the original Bemisia tabaci (A biotype), which can no longer be found in the United States. Last modified on Nyoike TW, Liburd OE, Webb SE. Maynard DN, Cantliffe DJ. While she is feeding she may lay eggs, often in a semi-circular arrangement as she swivels her body around her feeding site. The citrus whitefly, Dialeurodes citri(Ashmead), was once the most important citrus pest in Florida, but today it ranks below the snow scale, citrus rust mite, and several others. It transmitted new plant-pathogenic viruses that had never affected cultivated crops and in… Figure 15. Female longevity can range from 10 to 24 days during which time she can lay between 66 and 300 eggs, depending on host plant and temperature. (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Heavy infestations of adults and their progeny can cause seedling death, or reduction in vigor and yield of older plants, due simply to sap removal. Whitefly infestations have also been reduced with the use of UV-absorbing greenhouse plastic films. Bemisia vectors several serious plant-pathogenic geminiviruses in the United States. The body of the female measures 0.96 mm from the tip of the vertex (head) to the tip of the abdomen, while the male is somewhat smaller at 0.82 mm. Another way to differentiate adult Bemisia and Trialeurodes vaporariorum is to examine the compound eyes using a microscope. Host plant resistance offers limited hope for whitefly management. The designation of this insect as a new species is not universally accepted and I will refer to Bemisia tabaci B biotype (= Bemisia argentifolii) as Bemisia. 'Zucchini Elite' showing symptoms of Bemisia-induced squash silverleaf disorder. For example, smooth-leaved varieties of cotton and soybean are less preferred by ovipositing female Bemisia than are hairy-leaved varieties. The distal end of the egg becomes dark brown just before the first nymphal instar ecloses. The following scientific names of soybean are found in different scientific papers: ( Glycine max (L.) Merrill) ( Glycine max (L.) Merril) ( Glycine max (L.) Merr.) The sweetpotato or silverleaf whiteflies: biotypes of. Homeowners would be best advised to treat populations before they reach outbreak levels and to spray immature whiteflies with a mixture of insecticidal soap or insecticidal oil in water (see label for directions). How to identify whitefly through its biology - Life cycle - Damage causing stages 5. It is widely distributed throughout the Caribbean Islands, Central and South America, and Mexico.

The body remains light yellow with a light dusting of wax. A native of India, it appears to have been introduced into Florida sometime between 1858 and 1885 (Morrill and Back 1911). The common name silverleaf whitefly is an alternative to poinsettia whitefly and the scientific name is Bemisia tabaci. Photograph by Heather McAuslane, University of Florida. Much mortality is caused by minute parasitic wasps (parasitoids) in the aphelinid family. Adult coccinellid predator of Bemisia nymphs, Delphastus catalinae (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Loopers can occur anytime throughout the growing season. feeding on Bemisia nymphs. Sooty mold grows on honeydew-covered substrates, obscuring the leaf and reducing photosynthesis, and reducing fruit quality grade. (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Figure 4. The resultant air space reflects light, causing the silvery color. Figure 20. The crawlers usually move only a few centimeters in search of a feeding site but can move to another leaf on the same plant. (ed.). (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Red-eyed nymphal or "pupal" stage of Bemisia. Tomato irregular ripening was first noted in Florida tomatoes in 1987. Description of a species of, Brown JK, Frohlich DR, Rosell RC. Normally, they feed almost exclusively on leaves and don't cause significant damage, but under some conditions, populations can flare as high as 150 per square metre. Of the important vegetables crops grown in Florida, Bemisia is a major pest of tomato, peppers, squash, cucumber, beans, eggplant, watermelon, and cabbage. 1986. 'Florida Lanai' cherry tomato showing internal symptoms of Bemisia-induced tomato irregular ripening disorder (bottom) and control fruit from uninfested plant (top). Adult whiteflies emerge through a T-shaped slit in the integument of the last nymphal instar. Liu T-X, Stansly PA. 1999. If the exuvia has a round hole in it rather than a slit, an adult parasitoid emerged. Privacy Figure 18. It is whitish-green in color and has two yellow spots, the mycetomes, visible in the abdomen through the integument (skin). During the growing season, geminivirus-infected plants can be rogued out and destroyed. Migrating individuals usually develop on plants that are senescing. Infestations of whiteflies, especially in greenhouses, may occasionally be a mixture of Bemisia and Trialeurodes vaporariorum (Westwood), the greenhouse whitefly. They initiate feeding on the lower surface of a leaf, also feeding in the phloem. Even if fruits appear normal externally, the internal tissue may be white, hard, and unripe. 3-11. Many species of insects, mites, and spiders feed on immature and adult whiteflies. McAuslane HJ, Johnson FA, Colvin DL, Sojack B. Bemisia nymph infected with the entomopathogenic fungus, Paecilomyces fumosoroseus (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Photograph by Jack Dykinga, USDA. (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). The University of Minnesota is an equal opportunity educator and employer. Newly laid eggs of Bemisia are pale yellow while those about to hatch are dark brown. BANDEDWINGED WHITEFLY SCIENTIFIC NAME: Trialeurodes abutilonea (Haldeman) CLASS: Insecta ORDER: Hemiptera FAMILY: Aleyrodidae Nevertheless, it is still a serious pest in Florida. The honeydew can stick cotton lint together, making it more difficult to gin and therefore reducing its value. Before 1986, it was only an occasional pest of cultivated crops. (right) within body of Bemisia nymphs. Scientific name Trialeurodes vaporariorum Scientific name: Aleurodicus dispersus Russell and Bemisia tabaci Gennadius Common name: Glasshouse whitefly Scientific name: Trialeurodes vaporariorum Plants affected: Many house-plants and greenhouse plants Main symptoms: Sticky honeydew on foliage, black sooty moulds, small white-winged Figure 11. Taxonomy and biology. Lacewing larva (Chrysoperla sp.) (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Bemisia can cause economic damage to plants in several ways. Figure 6. In Florida, our main concerns are the tomato yellow leaf curl virus (TYLCV), tomato mottle virus (TMoV), and bean golden mosaic virus (BGMV). Contact U of M | The sweetpotato whitefly, Bemisia tabaci (Gennadius), has been recorded in the United States since the late 1800s. The female lands on a plant, using visual stimuli such as plant color, and walks or flies to the lower surface of a leaf. Bemisia populations can also be reduced by predation.  SCIENTIFIC NAME: As far as we know, the sexes do not rely on pheromones to locate one another. Ecologically, aleyrodids are the tropical equivalent of aphids (see Chapter 11). Figure 17. The soybean nodule fly (SNF), Rivellia quadrifasciata (Macquart), is Widely distributed in the Eastern United States (Namba 1956). Figure 5. U of M, CUES: Center for Urban Ecology and Sustainability, Back to Pest Identification Pupa of Encarsia nigricephala (left) and Eretmocerus sp. Whitefly eggs are oval in shape and somewhat tapered towards the distal end. It has been estimated that, in 1989, Florida tomato growers lost $25 million to tomato irregular ripening. Domain: Eukaryota. 2008. The egg is pearly white when first laid but darkens over time. 1990.  ORDER: Hemiptera Photograph by James Castner, University of Florida. Species Profile: Soybean Cyst Nematode. The remaining white, transparent "shell" is called the exuvia. This holds true for many plant species. The red-eyed nymphal stage is also less flattened and more convex in shape. Common Name(s) Whiteflies, citrus whitefly, ash whitefly, greenhouse whitefly, and many other related names Scientific Name(s) Multiple, all in the Aleyrodidae family of insects Family Aleyrodidae Origin Worldwide The most common parasitoids attacking Bemisia in Florida are in two genera, Encarsia and Eretmocerus. OneStop | Directories | Search The B biotype was described in 1994 as a new species, Bemisia argentifolii Bellows & Perring. The fourth and red-eyed nymphal stages combined lasts for five to six days. 1995. Care should be taken to cover the lower surface of the leaves. The upper and lower compound eyes of Trialeurodes vaporariorum are completely divided whereas they are joined by one ommatidium in Bemisia. However, in 1986 in Florida, the insect we called Bemisia tabaci became an extreme economic pest. The Florida-grown field crops of potato, peanut, soybean and cotton are heavily attacked by Bemisia. Figure 3. Under certain climatic conditions, usually wet and warm, Bemisia populations can be drastically reduced by natural epizootics of entomopathogens. Soybean meal, or soymeal, is the material remaining after solvent extraction of oil from soybean flakes, with a 50% soy protein content. In 1917 the American Elmer Drew Merrill (1876-1956), later Dean of the University of California College of Agriculture, Berkeley campus, argued convincingly that, according to international botanical rules, the correct botanical name of the soybean should be Glycine max (L.) Merrill. Photograph by Shahab Hanif-khan, University of Florida. (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Bemisia is widely polyphagous, feeding on over 500 species of plants in 74 families. and Diagnosis, GREENHOUSE WHITEFLY throughout much of southern Europe, Africa, India, and has recently moved into Australia. asia, Africa, North (Florida, Hawaii), South and Central America, the Caribbean, Europe (restricted), Oceania. It is present Chemoreceptors on the tip of her mouthparts and within her mouthparts sense the leaf's chemical composition. GREENHOUSE WHITEFLY SCIENTIFIC NAME: Trialeurodes vaporariorum (Westwood) CLASS: Insecta ORDER: Hemiptera FAMILY: Aleyrodidae This stage is more yellow than the fourth instar and the mycetomes are less visible. The egg obtains moisture through this stalk.  FAMILY: Aleyrodidae, Back to Pest Identification and Diagnosis, (C) Regents of the University of pp. Adult Bemisia argentifolii Bellows & Perring or Bemisia tabaci (Gennadius), B strain. Several species of Eretmocerus are also common throughout the state. Common name Greenhouse whitefly (GHW) and Sweet potato whitefly (SPW). Photograph by Jack Dykinga, USDA. It is now found throughout Florida and parts of other Gulf States and California and in greenhouses in many parts of the United States. These are called trivial flights. Female of an Eretmocerus species host-feeding on Bemisia nymph. When adult and immature whiteflies feed, they excrete honeydew, a sticky excretory waste that is composed largely of plant sugars. Figure 1. There is no molt between the fourth nymphal instar and the red-eyed nymphal stage but there are morphological differences. Within a few hours, their two pairs of wings become iridescent white due to the deposition of a powdery wax. Tomato Yellow Leaf Curl Virus (TYLCV) – a disease caused by whitefly - Symptomatic identification 6. In protected plant culture, such as greenhouses, it is not possible to rely on natural biological control. In 1753 the Swedish botanist Linnaeus called it Dolichos soja ; this was also its first scientific name, and the first time the "soy" cognate had been used to describe the plant. Several cultural controls can reduce Bemisia populations and lessen their impact on crops. (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Intercept, Ltd., Andover, UK. Figure 14. She tests the suitability of the plant by probing the leaf with her piercing-sucking mouthparts and ingesting a small amount of sap. Whiteflies do not enter greenhouses or areas covered with this type of plastic as frequently as they do greenhouses covered in non-UV-absorbing material. Tomatoes that develop on plants that are heavily infested with whiteflies may incompletely develop external color, resulting in streaking. If the host plant is deemed acceptable, she will insert her mouthpart stylets into the phloem from where she sucks plant sap. (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Tomato and bean breeders are attempting to develop varieties with resistance to geminiviruses, but these varieties are still some time from commercialization. Feeding by immature whiteflies causes newly developing leaves, but not the leaves on which they are feeding, to take on a silvery appearance due to the separation of the upper epidermis from the underlying cell layer. Fruits that develop on silvered plants may be bleached, and are of lower quality grade. The red-eyed nymphal stages of Bemisia and Trialeurodes vaporariorum can be distinguished easily in a mixed infestation. Suppression of whiteflies, Tsai JH, Wang K. 1996. Bemisia is primarily a pest of cultivated plants in tropical and warm temperate regions of the world. Photograph by Yasmin Cardoza, University of Florida. No varieties of host plants have been found to be highly resistant to whiteflies themselves, however, some plant factors are not preferred by whiteflies. species are specialist whitefly predators, such as Delphastus catalinae (LeConte) and Nephapsis oculatus (Blatchely). Scientific Name and Common Name Kingdom Plantae – Plants Subkingdom Tracheobionta – Vascular plants Superdivision Spermatophyta – Seed plants Division Magnoliophyta – Flowering plants Class Abstract Whiteflies (Homoptera: Aleyrodidae) are small delicate insects with sucking mouthparts. Increase in the population density of Bemisia tabaci, a threat of widespread virus infection of legume crops in Brazil. Whitefly and its damage 4. Bemisia is difficult to control with insecticides for two reasons; adults and immatures infest the lower surfaces of leaves which are difficult to reach with insecticide sprays and they have developed resistance to many insecticide chemistries. Influence of foliar pubescence on incidence and parasitism of. Adults that emerge may simply fly up the same plant or over to another Whiteflies: their Bionomics, Pest Status and Management. Photograph by T.X. Some individuals however, are primed for short-distance migration of up to several kilometers. Soya, Glycine max, soybean: Philippine Herbal Mediciines - An illustrated compilation by Dr Godofredo Umali Stuart, with botanical information, chemical properties, folkloric uses and medicinal studie3s Scientific … In warm or tropical climates and especially in greenhouses, whiteflies present major problems in crop protection. These migrations can often be massive and can lead to severe infestation of newly planted crops. (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). Adult Bemisia are soft and whitish-yellow when they first emerge from their nymphal exuvia. The mycetomes are yellow. Bandedwinged whitefly: Trialeurodes abutilonia Greenhouse whitefly: Trialeurodes vaporariorum Sweetpotato whitefly: Bemisia tabaci biotype B The ornamental host plants of Bemisia are too numerous to list, but include (Bemisia = sweetpotato whitefly B biotype, Bemisia tabaci (Gennadius), or silverleaf whitefly, Bemisia argentifolii Bellows & Perring). The broader end has a short stalk, 0.024 mm, that is inserted by the ovipositing female into the leaf. After harvest, crop residue (tomato plants, in particular) should be removed so that there is no plant material for large numbers of whiteflies to carry over the crop-free period, usually the height of summer. It is oval in shape and measures approximately 0.27 mm in length and 0.14 mm in width. Other physiological disorders caused by Bemisia include lettuce leaf yellowing and stem blanching, carrot light root, pepper streak, Brassica white stem, and chlorosis of new foliage of many plants. 27–50 in J.
