Effect of Alternative Feeding with Artificial Diets and Natural Prey on Oviposition of Delphastus catalinae (Horn)
Effect of alternative feeding with artificial diets and whitefly Bemisia tabaci (Gennadius) on oviposition of Delphastus catalinae (Horn) were investigated. The results show that adult D. catalinae could all resume to lay eggs within 1-4 days when they were fed with whiteflies after being fed with artificial diet for 15, 25, and 35 days, but oviposition duration and fecundity decreased with increasing of feeding days on artificial diets. Fed with different artificial diets for 35 days and then with whiteflies, D. catalinae showed different fecundity and oviposition duration, 246.0 eggs and 68.33 d on eggs of Corcyra cephalonica (Stainton), 203.33 eggs and 61.00 d on defatted powder of pupae of Tenebrio molitor (Linn.), and 128.33 eggs and 57.00 d on defatted powder of mature larvae of Bactrocera dorsalis Hendel.
