Abstract

ABSTRACT Cacao mealybug (Planococcus minor) is one of the contributing factors in decreasing productivity of cacao in the last years. Cacao mealybugs attack the young cacao fruits, by sucking them until dry and die. To solve the problems, it is necessary to improve the pest control in cacao plantions. One of them is by using gamal (Gliricidia maculata) as bioinsecticides. Gamal contains flavonoid compounds which have potential as insectisides. This research was conducted at the Integrated Laboratory and Technology Innovation Center (LTSIT) and Zoology Laboratory, FMIPA, University of Lampung. This study aims to determine the effectiveness of bioinsecticides formulas from water extract leaf powder of gamal West Lampung Kultivar (KLB) and North Lampung Kultivar (KLU) in cacao mealybug mortality. This formula was made with combine water extract leaf powder of gamal West Lampung Kultivar (KLB) and North Lampung Kultivar (KLU) with a ratio of 1:1 (KLB:KLU) in formula 1, 1:2 (KLB:KLU) in formula 2, and 2:1 (KLB:KLU) in formula 3. The results of this study indicates that the formula 2 was more effective as bioinsecticide than formula 1 and formula 3.The percentage of cacao mealybug mortality in formula 2 was after 72 hours treatment reaches 73,3%. Keywords: Cacao Mealybug, Bioinscticide, Gamal, and Formula
