Abstract: The mixed Piper aduncum fruit and Tephrosia vogelii leaf extracts processed to form emulsifiable concentrates (EC) or wettable powder (WP) that actively control the cabbage pest Plutella xylostella. The objective of this study was to determine the effect of EC and WP formulations on the parasitoid Diadegma semiclausum. Their effects on parasitoid D. semiclausum can be seen from the mortality, life time, parasitization ability, and sex ratio of the parasitoid. Completely randomized design was used with 4 treatments and 6 replications. The thin layer residue method was used with EC and WP at twice the LC95 value determined for P. xylostella (appropriate controls were used). The EC and WP formulations had not effect on the mortality, the life time, parasitization ability or the sex ratio of the parasitoid D. semiclausum. These EC and WP formulations can be used to control the cabbage pest P. xylostella in field related to an integrated pest management system.
