Abstract

Liriomyzav sativae is a polyphage pest attacking various species of vegetable. The plant attacked by the insect may become dry or brovvn like bumed. The pest might decrease the yield of vegetable crop in the range of 40 to 70%. The research was conducted in Entomological Laboratory and screen house of the Department of Plant Pest and Disease, Faculty of Agriculture. Sriwijaya University Inderalaya, from March to August 2007. The research was aimed at knowing the effects of ideal temperature to store hosts parasitized by Opius sp. and functional respons of Opius sp. against the larvae of L. sativae. The research was designed as an experiment with 4 treatmcns and 3 repiications and 4 treatmenst pupae of L. sativae were stored under low temperature. Data collected through direct observation were then analyzed descriptively. The parameters observed were number of adult parasitoid emerged, mortality of parasitoid pupae, lite length of adult parasitoid, number and sex category of parasitoid progenies, and pre adult mortality of the parasitoid.The result showed that pupae stored 0 °C all died while those stored under 5 and 20 °C had the relatively same ability to become imago. Storing pupae under 10 °C caused 14.26% mortality. In general, it was better to store pupae under room temperature, indicated by low pupal mortality 5.09%. However, pupae under 5 °C were relatively good showed by lower pupal mortality compared to those stored under 10 °C, 7.72%. test of fimctional responses showed that the higher progeny was found in the treatment of exposing 15 L. sativae larval to Opius sp., and the lowest was found in the treatment of exposing 5 L. sativae. Larvae Opius sp. In conclusion, the optimal temperature to store parasitoid {Opius sp.) pupae is 5 °C and the more the host exposed to the that parasitoid, the more the host parasitized.
