KERAGAMAN ARTHROPODA PADA SACHA INCHI DI LAHAN KERING

Abstract

<em>Dryland is one of the most potential ecosystems for cultivated land. Sacha inchi (Plukenetia volubilis L.) is perennial plant originated from Peru and spread to the tropic area like China and Thailand. Arthropods in the plants can be a role as a pest, natural enemy, decomposer, and pollinator. This research purposed to specify diversity of Arthropods and its role in sacha inchi crop. This research has been carried out in June to December 2015 in Mojosongo, Kebak, Jumantono, Karanganyar, Central Java and Laboratory of Plant Pests and Diseases, Faculty of Agriculture, University of Sebelas Maret  Surakarta. The observation was implemented using absolute methods. Data were analyzed by descriptively about the diversity and the abundance of Arthropods on the sacha inchi plants. The result showed that on sacha inchi plant there were 75 families Arthropods consist of 13 orders those are Araneae, Ephemeroptera, Odonata, Orthoptera, Blattaria, Isoptera, Hemiptera, Homoptera, Thysanoptera, Coleoptera, Diptera, Lepidoptera, and Hymenoptera. The role of Arthropods on sacha inchi plant  8% as pest, 10% as the natural enemy (predators and parasitoids), and 82% others (decomposers and pollinators). The family diversity of the Arthropods was a low category (Shannon-Weaver index is 0.692) and Pielou evenness index is 0.164 so Arthropods’ evenness was low</em>
