Daftar Isi:
- A study was conducted to determine the species diversity of lepidoptera egg parasitoids on several crops in Solok.lepidopteran eggs were collected from rice, corn, tomato, and cabbage. A survey was conducted by using StratifiedPurposive Sampling Method. Two districts (Gunung Talang and Lembah Gumanti) were chosen as centre of the targetcrops. The results showed that five species of egg parasitoids were found parasitizing lepidopteran eggs. The speciesfound on rice were Telenomus sp., Tetrastichus sp., and Trichogramma japonicum parasitizing Scirpophaga incertulasand Hesperiidae with parasitization levels were 29.54; 13.02; and 2.05% respectively. The species found on corn wasTrichogrammatoidea spp. parasitizing Helicoverpa armigera with parasitization level was 29.07%. None of parasitoid wasfound to parasitize eggs of H. armigera on tomato. The egg parasitoid parasitizing Crocidolomia pavonana and Spodopteralitura on cabbage was Trichogramma chilotrae with parasitization level was 1.67%. The most abundance species oflepidopteran egg parasitoids were Telenomus sp.and Trichogrammatoidea sp. The diversity index of egg parasitoids onrice in different sample areas varied from 0.46 to 0.63 based on Simpsons index. It indicated that the species diversity oflepidopteran eggs was relatively low.Keywords: diversity, egg parasitoid, lepidopteran pest
