Abstract
Crocidolomia pavonana (Lepidoptera: Pyralidae) is one of Brassicaceae family plant pest such as cabbage, broccoli, cauliflower, mustard greens and turnips. Pest control using biopesticides such as Barringtonia asiatica L. (Kurz) has been studied. The development of biopesticides combined with papaya sap (Carica papaya) has never been done. The purpose of the study was to obtain a biopestiseda formulation from a mixture of bitung seed (B. asiatica) extract and papaya (C. papaya)sapwhich can control C. pavonana pests on cabbage plants. This research is an experimental study using a completely randomized design. Barringtonia asiatica extraction using a solvent fractionation method. The bioactivity of the biopesticide formula was evaluated based on the mortality of C. pavonana. The compound content in biopesticides was analyzed using LCMS. The results showed that bitung seed extract could kill C. pavonana larvae with LC 50 values of 5.325 g/L. Papaya sap can increase the toxic effect of deadly bitung seed extract from C. pavonana larvae with LC 50 value of 2.390 cc/l. The LCMS analysis showed that biopesticides contained 5 compounds considered as tetraheptacontylbenzene and 4 unknown compounds. The conclusion of this study is that biopesticides from a mixture of bitung seed (B. asiatica) and papaya (C. papaya)sap were effective in controlling C. pavonanapest on cabbage.
