Cacao moth is an important pest at the cacao ecosystem. Characteristic of pest is homo dynamic and endemic, which is very different to other pests. However, the entomologists reported that the cacao moth species in Indonesia is the same with the rambutan moth, but their biotypes are different. The biotype or strain adapted to cacao, can distribute and life in the area. The presence of insects are caused by both expansion of cacao planting acreage and introduction of cacao plant materials to the cacao production areas. It causes fruit destruction with loss of seed production of 82.20%. Control measures of cacao moth are interrelated with bioecology of pest, and farmers as controlling agent. However, it is necessary to understand motivation, attitude and attention of farmers as well as their local experiences, social and economic conditions. The control methods of cacao moth that can be integrated with farmer's motivation and experiences are as follows: 1) earlier harvesting followed by 5-7 days interval harvesting, to cut life cycle of cacao moth, 2) harvest all fruit during 1-2 months, and followed by harvesting mature fruits of alternative hosts, such as Nephelium lappaceum, Cynometra cauliflora, Cola nitida, Mangifera indica L, Anona squamosa, Averrhoa carambola L, Citrus sinensis L, Lansium domesticum L., 3) garden sanitation by cleaning up garbages on soil surface, reduce plant coverage by prunning horizontal branches, 4) kill white fleas, green fleas and Aphis sp. which are honeydew producer as food of cacao moth. Those practices will limit the population of pupae and the moth, 5) avoid utilization of pesticide to conserve natural enemy of cacao moth, but maintain nectars-producing plants to support the life of natural enemy, 6) isolate borders among small holders at least 300 m and free from alternative host plants of cacao moth.
