abstract nymphal survival and crawlers movement of bemisia tabaci (homoptera: aleyrodidae) on different varieties of cotton, gossypium hirsutum, was studied on 5 different varieties including, varamin, kucker-312, bulgar-557, sahel-80, and native (red leaf/red boll) at 24±2 °c, 65±5% rh, 16:8 (l: d) photoperiod in the greenhouse condition. crawlers' movement was significantly different on the v...

Members of the whitefly Bemisia tabaci species complex cause millions of dollars of damage globally and are considered one of the world's most invasive species. They are capable of causing extensive damage to major vegetable, grain legume and fiber crops. All member of the species complex are morphologically identical therefore, data from the partial mitochondrial cytochrome oxidase subunit I (...

HIGHLIGHTS A detailed description and illustration of stage-specific morphological characters whiteflies Bemisia tabaci (Asia II 5) Trialeurodes vaporariorum. Developmental biology the Preliminary information for field-level identification formulation IPM strategies. First its kind comparative study morphology in Northwestern Himalayan region.

Brazil is one of the main tomato (Solanum lycopersicum) producers worldwide. Nevertheless, considerable part of the production is lost due to Bemisia tabaci (Genn.) B biotype attacks. Resistant plants can be an important method for controlling this pest in an integrated pest management. Tests for evaluating some biological aspects of B. tabaci were carried out on 18 tomato genotypes, in control...

"Candidatus Hamiltonella defensa" is a facultative endosymbiont of the whitefly Bemisia tabaci. Herein, we report the first draft genome sequence of "Candidatus Hamiltonella defensa" from the invasive Mediterranean cryptic species of the B. tabaci complex. The 1.84-Mbp genome sequence comprises 404 contigs and contains 1,806 predicted protein-coding genes.

While every individual of Bemisia tabaci (Hemiptera: Aleyrodidae) harbors the primary symbiont (P-symbiont) Portiera, the infection frequencies of the six secondary symbionts (S-symbionts) including Hamiltonella, Arsenophonus, Cardinium, Wolbachia, Rickettsia and Fritschea vary greatly among different populations. To characterize the factors influencing the infection dynamics of the six S-symbi...

BACKGROUND Although whiteflies (Bemisia tabaci complex) are an important pest of cotton in Pakistan, its taxonomic diversity is poorly understood. As DNA barcoding is an effective tool for resolving species complexes and analyzing species distributions, we used this approach to analyze genetic diversity in the B. tabaci complex and map the distribution of B. tabaci lineages in cotton growing ar...
