Abstract
The insect egg parasitoid is a potential agent of biological control for pest, especially concerning the development of technology alternative pest control. The existing species of egg parasitoids in rice agroecosystems needs is known for their use as pest control an effective and efficient. The research aimed to determine of diversity, dominance, and parasitization levels for species of egg parasitoids in rice agroecosystems based on plant growth. The location research and sampling of parasitoids were done in Matangkuli and Syamtalira Aron sub-districts, North Aceh district, and Kuta Malaka sub-districts, Aceh Besar district, Province Aceh. The sampling was done in the vegetative stage from 20 to 40 and generative from 70 to 90 days after planting (DAT). Groups of eggs collected from the sampling location were then observed and identified at the Laboratory of Plant Pests and Diseases, Faculty of Agriculture, Malikussaleh University, Aceh. The results showed that egg parasitoids found in the rice agroecosystem form Order Hymenoptera, superfamily Chalcidoidea, species Ooencyrtus malayensis (Encyrtidae) and Tetrastichus schoenobii (Eulophidae). Superfamily Platygasteroidae, species Telenomus triptus (Scelionidae) and Hadronotus leptocorisae (Scelionidae). The number of individuals and diversity of egg parasitoids were low in vegetative than generative. The evenness index in both growth stages belongs to high. Species of T. triptus and T. rowani were dominant egg parasitoids found in the rice agroecosystem in both growth stage. The level of parasitization to parasitoid T. triptus, T. rowani, and Te. schoenobii is generally known as > 50%, species O. malayensis and H. leptocorisae less than 50%
