A critical feeding period is the time after which 50% of a given species of insect can be removed from its food source and complete development by undergoing adult eclosion. The critical feeding period was determined for the greenhouse white fly, Trialeurodes vaporariorum, and the sweet potato whitefly, Bemisia tabaci (Biotype B) (Homptera/Hemiptera: Aleyrodidae). Fourth (last) instar and phara...

The cotton intercropping experiment was conducted for the management of sucking pests, viz. leafhopper, Amrasca biguttula Ishida (Hemiptera: Cicadellidae); whitefly, Bemisia tabaci Gennadius Aleyrodidae) and thrips, Thrips Linderman (Thysanoptera: Thripidae) in desi cotton, Gossypium arborium. results study revealed that less mean population leafhopper nymphs, whitefly thrips adults recorded fr...

"Candidatus Portiera aleyrodidarum" is the obligate primary endosymbiotic bacterium of whiteflies, including the sweet potato whitefly Bemisia tabaci, and provides essential nutrients to its host. Here we report two complete genome sequences of this bacterium from the B and Q biotypes of B. tabaci.

ABSTRACT The effect that Tomato yellow leaf curl virus (TYLCV)-infected resistant tomato plants may have on virus epidemiology was studied. Four tomato genotypes that exhibit different levels of viral resistance, ranging from fully susceptible to highly resistant, served as TYLCV-infected source plants. Viral acquisition and transmission rates by white-flies following feeding on the different s...

The whitefly, Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) biotype B, is one of the most destructive invasive pests of field and glasshouse crops, and has a high tolerance to heat. Our previous work found that whitefly females are more heat tolerant than males. In the present study, real-time PCR and double-stranded RNA (dsRNA) methods were used to explore the role of heat shock protein ...

Red whitefly fungus, Aschersonia aleyrodis (Webber) is a fungal pathogen of nymphs blackfly, Aleurocanthus woglumi (Ashby) and whitefly, Dialeurodes citri (Ashmead) on the citrus plant. It used as promising biological control agent. In present study, attempts have been made to check efficacy A. biopesticides for management blackfly under laboratory condition. Probit analysis LC50 values 2nd ins...

The whitefly (Bemisia tabaci Gennadius) is a notorious devastating sap-sucking insect pest that causes substantial crop damage and yield losses due to direct feeding by both nymphs adults also through transmission of viruses diseases. Although the foliar application synthetic pesticides crucial for efficient control B. tabaci, it has adverse effects such as environmental pollution, resistance r...
