Penicillum oxalicum spg1: A novel entomopathogenic fungus isolated from mummified Bemisia tabaci (Gennadius) of cotton

Toxicological and biochemical basis of synergism between the entomopathogenic fungus Lecanicillium muscarium and the insecticide matrine against Bemisia tabaci (Gennadius)

The sweetpotato whitefly Bemisia tabaci (Gennadius) was challenged with different combinations of matrine (insecticide) and Lecanicillium muscarium (entomopathogenic fungus). Our results revealed a synergistic relationship between matrine and L. muscarium on mortality and enzyme activities of B. tabaci. To illustrate the biochemical mechanisms involved in detoxification and immune responses of ...

Natural enemies of cotton whitefly bemisia tabaci gennadius homoptera aleyrodidae in fars province of iran

Efficiency of Bemisia tabaci (Gennadius) populations from different plant-hosts for acquisition and transmission of cotton leaf curl virus

Whitefly (Bemisia tabaci) populations collected from five crop plants, viz brinjal, cotton, potato, tomato, soybean and a weed, Sida sp., and maintained on respective host plants were studied for virus acquisition from diseased cotton plant and its subsequent transmission to healthy cotton plants. The presence of virus in whitefly and diseased plants was established by PCR amplification of CLCu...

Taxonomic Position of Iranian Isolates of Eretmocerus mundus (Merect), a Parasitoid of Bemisia tabaci (Gennadius)

Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is one of the most important pest of vegetable and fruit crops. This polyphagous pest has a range of natural enemies including the parasitoid Eretmocerus mundus (Merect) (Hymenoptera: Aphelinidae). To determine the molecular profile and taxonomic status of Iranian isolates of E. mundus, parasitized B. tabaci samples were collected from cotton...

The Effect of Insecticide Treatments in Cotton Fields on the Levels of Parasitism of Bemisia tabaci (Gennadius) sl.1

Populations of whiteflies [Bemisia tabaci (Gennadius) sl.] and the rates at which they were parasitized in cotton fields in Israel and California were monitored over a number of years. Studies took place both in fields that were treated with insecticides and in untreated fields and permitted us to assess the influence of insecticidal treatments upon percentage parasitism. The results showed tha...
