Among the predators on pests in oil palm plantations the asopin bugs are the more interesting ones due to their naturally occurring large numbers their activities both at the nymphal and adult stages their ability to find prey and their substantial feeding on caterpillars.

Abstract

The species complex of Eocanthecona-Cantheconidea was studied four from Sumatra two from Java two from Kalimantan and one from Irian Jaya. After rearing the different nymphal instars were characterised and the duration of their development determined. In mass rearing Eocanthecona furcellata was multiplied by feeding with caterpillars stocked in the freezer. There was no difference in rearing results using live or frozen caterpillars. This method is now used for mass production of predatory Pentatomidae (Asopinae) and Reduviidae. Releases undertaken showed that it was possible to establish the asopin bugs in the field and that their impact was significant. After treatment with viral suspensions they also help in the spread of insect viruses. They feed on wide range of hosts and several alternative hosts. It is thus possible for them to survive in the field even when the caterpillars on oil palm foliage have disappeared. Among the predators on pests in oil palm plantations the asopin bugs are the more interesting ones due to their naturally occurring large numbers their activities both at the nymphal and adult stages their ability to find prey and their substantial feeding on caterpillars. The species found in Indonesia are more numerous than elsewhere. With the method of mass rearing with frozen food and the judicious management of these species Eocathecona-Cantheconidea could become effective predators in oil palm agroecosystems
