Abstract:
One of the problems is that there is increased production of coconut pests attack crops (OPT) coconut leaf beetle (Brontispa longissima Gestro). Alternative control is environmentally friendly with the use of natural enemies. Some of the potential natural enemies that can be used are predators cecopet (Euborellia annulata Fabricus) locally. The purpose of this study was to determine the ability of the imago cecopet prey (E. annulata Fabricus) on local coconut leaf beetle larvae (B. longissima Gestro). This research was conducted at the Laboratory of Plant Pest Faculty of Agriculture, University of Riau from September to November 2012. This research used Completely Randomized Design (CRD) with 5 treatments and 4 replications that is one female, one male, two females, two males, and a couple (male and female). The treatment is the treatment most prey 2 tail female imago capable of coconut leaf beetle larvae prey (B. longissima Gestro) that is 85% more, compared to other treatments that imago pair of male and female 75%, male imago treatment 2 tails 70%, treatment 1 tail female imago 63.75%, and treatment 1 tail male imago 60%. Most predation occurs in the first hour for the treatment of female imago 2 heads, 1 tail imago females and 1 male imago tail. In treatment 2 tails and a pair of male imago imago males and females, most predation occurs in the second hour.
