مطالعه مورفوژیک و بیولوژیک مگس سفید گلخانه [Trialeurodes vaporaiorum (Westwood Homoptera: Aleyrodidae)] در اصفهان
The difficulties of control of greenhouse whitefly on crops and greenhouse plants make extensive studies and investigations necessary in different areas of Iran. Morphological and biological studies were carried out on a prevailing species of greenhouse whitefly, Trialeurodes vaporariorum Westwood, in Isfahan. In this study, six species of whiteflies T. vaporariorum on Althaea sp. and Lantana...

full textECOLOGY AND BEHAVIOUR Bemisia tabaci (Homoptera: Aleyrodidae) Biotypes in India
Host plant performance, esterase, and virus transmission tests revealed cassava-strain and sweetpotato-strain populations of whiteßy Bemisia tabaci (Gennadius) biotypes in India. Individuals from the sweetpotato-reared population did not breed on cassava, Manihot esculenta Crantz, and the cassava-strain-reared individuals failed to develop on sweetpotato, Ipomoea batatus (L.) Lam. Eggplant, Sol...
full textInsecticide resistance in Bemisia tabaci (Homoptera: Aleyrodidae) populations from Crete.
The resistance levels to alpha-cypermethrin, bifenthrin, pirimiphos-methyl, endosulfan and imidacloprid were determined in Bemisia tabaci (Gennadius) from Crete. Five B tabaci populations collected from greenhouse and outdoor crops were bioassayed and compared with a reference susceptible strain. Bemisia tabaci collected in a floriculture greenhouse exhibited the highest resistance against all ...
full textToxicity of plant essential oils to Trialeurodes vaporariorum (Homoptera: Aleyrodidae).
A total of 53 plant essential oils were tested for their insecticidal activities against eggs, nymphs, and adults of Trialeurodes vaporariorum Westwood, using an impregnated filter paper bioassays without allowing direct contact. Responses varied according to oil type and dose, and developmental stage of the insect. Bay, caraway seed, clove leaf, lemon eucalyptus, lime dis 5 F, pennyroyal, pepp...
full textDiscovering new insect viruses: whitefly iridovirus (Homoptera: Aleyrodidae: Bemisia tabaci).
Adult whiteflies, Bemisia tabaci (Gennadius), collected from the field were screened for viral pathogens using a cell line from the silverleaf whitefly, B. tabaci, B biotype (syn. B. argentifolii). Homogenates from the field-collected whiteflies were applied to cell cultures and checked for cytopathic effects (CPE). Cells were observed to develop cytoplasmic inclusions and to have a change in m...
