| diversity and localization of bacterial endosymbionts from whitefly species collected in brazil. | whiteflies (hemiptera: aleyrodidae) are sap-sucking insect pests, and some cause serious damage in agricultural crops by direct feeding and by transmitting plant viruses. whiteflies maintain close associations with bacterial endosymbionts that can significantly influence their biology. all whitefly species harbor a primary endosymbiont, and a diverse array of secondary endosymbionts. in this study, we surveyed 34 whitefly populations collected from the states of sao paulo, bahia, minas gerais an ... | 2014 | 25259930 |
| mitochondrial dna variability and development of a pcr diagnostic test for populations of the whitefly bemisia afer (priesner and hosny). | the whitefly, bemisia afer (hemiptera; aleyrodidae), is emerging as a major agricultural pest. the current identification methods based on adult and pupal morphology are laborious and unreliable. a diagnostic polymerase chain reaction (pcr) protocol was developed for the first time in this study to discriminate b. afer from other whitefly species. primers specific to mitochondrial cytochrome oxidase i gene (mtcoi) were designed to amplify a band of approx 650 bp. the pcr products were sequenced ... | 2007 | 17401147 |
| a geographic distribution database of the neotropical cassava whitefly complex (hemiptera, aleyrodidae) and their associated parasitoids and hyperparasitoids (hymenoptera). | whiteflies (hemiptera, aleyrodidae) are represented by more than 1,500 herbivorous species around the world. some of them are notorious pests of cassava (manihot esculenta), a primary food crop in the tropics. particularly destructive is a complex of neotropical cassava whiteflies whose distribution remains restricted to their native range. despite their importance, neither their distribution, nor that of their associated parasitoids, is well documented. this paper therefore reports observationa ... | 2015 | 26798295 |
| biology of bemisia tuberculata bondar (aleyrodidae) and parasitism by encarsia porteri (mercet, 1928) (hymenoptera, aphelinidae) on cassava plants. | the whitefly bemisia tuberculata has caused serious damage to cassava producing areas in the state of mato grosso do sul. however, little is known about the biological characteristics of this species. the objective of this study was therefore, to monitor the development of this species bred on cassava plants under controlled greenhouse conditions, and to determine its most vulnerable stages and its reproductive capacity, as well as measuring the length and width each stage of development. to obt ... | 2012 | 23295520 |
