Diversity of Hymenopteran parasitoid in agricultural and primary forest in Lubuk Kilangan, Padang, West Sumatera, Indonesia

Abstract

A hymenopteran parasitoid is an important natural enemy for many orders of insect pests. This group can control pests specifically in the agricultural ecosystem. The research aimed to study the diversity of hymenopteran parasitoids in the agricultural and primary forest ecosystems. A purposive random sampling method was used to determine the research location. Malaise and yellow trap were used to collect the samplings. The research location was agricultural and primary forest ecosystems. The result showed that families of the hymenopteran parasitoid in the dominant number of individuals and morphospecies were Braconidae, Ichneumonidae, and Scelionidae. According to the result, the diversity index in both ecosystems was high [4.879 for primary forest and 4.675 for agricultural]. The evenness index in both ecosystems was also high [0.905 for primary forest dan 0.887 for agricultural forest]. The similarity index in both ecosystems was classified as high [0.607 respectively].
