Abstract

Cashew plant is the one of export commodity that has high economic value compared to the other commodities. Sanurus indecora is one of major pest in cashew, causing decreased quality and quantity of products. The aims of this experiments were to the develop integrated pest management of S. indecora, by: (a) utilization and enviroment manipulation of cashew plantation using intercropping plants to control S. indicora, (b) utilization of natural enemies, specially Synnematium sp., to control S. indecora. The experiment consisted of : (1) the effect of intercropping plant extracts as botanical pesticide on S. indecora mortality at laboratory, (2) the effect of medium substances on Synnematium sp. growth, as well as the effect of concentration of Synnematium sp. suspension on S. indecora mortality at laboratory. Botanical pesticides that were used in this experiment was made from extraction of intercropping plants: extraction of sesame seed, of cassava leaves and pineapple fruit. All experiments were arranged in complete randomized design. The results showed that 0.5 mg/10 mL water of sesame seed extract, 0.1 mg/10 mL water of cassava leaves extract and 2.0 mg/10 mL pineapple fruit extract concentrations resulted average 76.67%, 66.67%, and 63.33% S. indecora mortalities at 24 hours after application, respectively. The second experiment showed that the growth medium containing rice straw resulted the best growth of Synnematium sp. colonies than the other treatments and 0.1 g/mL water of Synnematium sp. mycelium resulted the high mortality (57,5%) at 5 days after application.
