Effect of feeding on different stages of Bemisia tabaci(Gennadius) on development of Delphastus catalinae(Horn)

Respectively provided the eggs,nymphs and adults of Bemisia tabaci (Gennadius) for rearing of Delphastus catalinae (Horn),the results showed that the eggs of B. tabaci are the most favor food for rearing of D.catalinae. Feeding on the different stages of B. tabaci affected the development of D. catalinae. After preyed the whitefly egg,D. catalinae develops quickly (duration of larva to adult emergence as 19.18d),with high survival rate (survival rate of larva to adult emergence as 78.57%),high oviposition (131.25 eggs/female) and fast population increase (rm=0.0724). The whitefly egg is the best food for artificial rearing of D. catalinae.
