Abstract
The biology of Trissolcus latisulcus Crawford was studied on eggs of Chrysocoris javanus Westw (Hemiptera: Scutelleridae) which is a serious pest of Jatropha curcas L.. The aim of this study was to investigate the biology of Trissolcus latisulcus as a basic knowledge for developing a more suitable biological control programme in controlling the pest C. j avanus . The current laboratory study was designed to evaluate developmental duration from egg to adult of C. j avanus under room condition temperature: 28.18 + 0.59°C and RH 56.33 + 4.27%. The results showed that the life cycle of immature T.latisulcus consisted of egg, larva ( three instars) , prepupa, pupa. The longevity period of each stadium was one day, four days, one day, and five days respectively. The development time from egg to adult took 12.66 + 1.22 days for female and 11.91 ± 0.73 days for males.The life time from egg to dead adult was 17.40 + 7.38 days for female and 23.70 ± 9.49 days for males. The egg of T.latisulcus was stalked type, the first instar larva was teleaform type and the third instar larva was hymenopteriform type. Keywords: Jatropha curcas L, Chrysocoris javanus Westw , Trissolcus latisulcus Crawford ,parasitoid eggs
