Potency of trissolcus latisulcus crawford (hymenoptera: scelionidae), an eggs parasitoid of chrysocoris javanus westw (hemiptera: cutelleridae), Pest on jatropha curcas l
Abstract
Results of preliminary field survey showed that Trissolcus latisulcus Crawford (Hyrnenoptera : Scelionidae) mostly found in the Jatropha curcas plants. It indicated that these eggs parasitoid may be has a highly potential prospect to control Chrysocoris javanus Westw (Hemiptera: Scutelleridae) which is a serious pest of Jatropha curcas L., but the information of this parasitoid is paucity. A laboratory experiment was conducted to investigate the potency of T. latisulcus as an eggs parasitoid of C. javanus for developing a more suitable biological control programe in controlling C. javanus. The results showed that T. latisulcus has high fecundity 95.70 + 18.34; daily egg-production per female 15.76 + 2.63; total egg production per female 29.30 + 25.96, reproduction time 6.10 + 0.88 days; sex ratio 1:3.83 and parasitoid capacity was 19.14 + 3.67 %.
