Abstract A summary of knowledge about B. tabaci autecology is given following some 50 years of research of this pest. The parameters that have been studied were developmental duration, survival, longevity, fecundity and sex ratio. Early records were mainly of field studies, but recent work concentrated more on laboratory under controlled conditions.

Prevalence of Wolbachia Infection in Bemisia tabaci
Current Microbiology, 2007Wolbachia are obligate intracellular bacteria present in reproductive tissues of many arthropod species. It has been reported that few silverleafing populations of Bemisia tabaci were positive for Wolbachia, whereas non-silverleafing populations were more likely infected with Wolbachia and all that infect B. tabaci are Wolbachia belonging to supergroup

Wolbachia Infections of the Whitefly Bemisia tabaci
Current Microbiology, 2003We report the first systematic survey for the presence of Wolbachia endosymbionts in aphids and whiteflies, particularly different populations and biotypes of Bemisia tabaci. Additional agriculturally important species included were predator species, leafhoppers, and lepidopterans.

Bemisia tabaci: A Statement of Species Status
Annual Review of Entomology, 2011Bemisia tabaci has long been considered a complex species. It rose to global prominence in the 1980s owing to the global invasion by the commonly named B biotype. Since then, the concomitant eruption of a group of plant viruses known as begomoviruses has created considerable management problems in many countries.

Monitoring Bemisia tabaci: A review
Agriculture, Ecosystems & Environment, 1986Abstract Most estimates of whitefly populations relate, according to the purpose of the survey, either to the adults or to the last two larval instars including the so-called “pupae”, these stages being easier to count than eggs or small larvae. Monitoring the adult population is done by visual counts or by catches with suction traps or yellow sticky

Oogenesis in the Bemisia tabaci MEAM1 species complex
Micron, 2016The whitefly Bemisia tabaci MEAM1 species complex has invaded several parts of the world in the past 30 years and replaced native whitefly populations in the invaded regions, including certain areas of China. One of the possible reasons for the invasion is that MEAM1 whiteflies are more fecund than native species.

The Whitefly Bemisia tabaci (Gennadius)
2017The whitefly Bemisia tabaci (Gennadius) is a species complex containing at least 35 morphologically indistinguishable cryptic species. Some members of the complex are pests of agricultural and horticultural crops in temperate and tropical regions. During the past 20 years, two species of the complex, Middle East-Asia Minor 1 (hereafter MEAM1) and ...

The Bemisia tabaci species complex
Crop Protection, 2001Abstract Bemisia tabaci (Gennadius) currently is believed to be a species complex, with many biotypes and two described extant cryptic species, B. tabaci and Bemisia argentifolii Bellows and Perring. This paper examines the historical record of B.

Bemisia tabaci (Homoptera: Aleyrodidae) Biotypes in India
Journal of Economic Entomology, 2003Host plant performance, esterase, and virus transmission tests revealed cassava-strain and sweetpotato-strain populations of whitefly 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 ...

The Bemisia tabaci Problem in Martinique
1992Since 1990, vegetable crops in Martinique have suffered severe problems caused by the rapid multiplication of the whitefly Bemisia tahuci (Gennadius) (Hcmiptera. Aleyrodidae). The same phenomenon is found throughout the Caribbean and into the South of United States, and seems to be linked to the existence of a special fom1 of this species ...
