| Summary: | The bioactivity of Aglaia odorata leaf extract were studied as insecticide to larval stage of Croc ido!om ia hinotalis . fn the research leaf cabbage was used for food of C. hinotalis . Observation and experimental resea rch were done at the laboratory . Research design used for experimental research is Co mpletel y Randomized Design . Data analysis for the bioactivity test was evaluated by using probit analysis and anal ysis of va riance . The results of the antifeedant test for non selelctive food was calculated using t- test. The test extract acted strongly, larval mortality increased markedly 2 days after treatment , then the mortality increased gradually and reached more or less a constant level 4 days after treatment. At this time , LC50 of crude extract againts instar III was 3. 73 % and 1. 9 8 % for topical and oral application , respectively. |
