Larvicidal and antifeedant activities of clove leaf oil against Spodoptera litura (F.) on Soybean. Economic losses due toinfestation by the soybean armyworm, Spodoptera litura can reach up to 100%. Some farmers often used insecticide to control thearmyworm. However, regular use of insecticide can cause several negative effects such as environmental pollution, residual toxicity,and health hazard for human. The objective of this research was to determine the larvicidal, antifeedant, and activities of cloveleaf oil (CLO) against the armyworm S. litura on soybean. The research was carried out at the plant pest control laboratory ofPoliteknik Pembangunan Pertanian Malang. Clove leaf oil was evaluated for its larvicidal and antifeedant activities against tenthird instar larvae of the armyworm. Completely randomized design was used with concentration levels of CLO as treatments.i.e. 0.4, 0.5, 0.67, 1.0, and 2.0% by volume. Profenofos 500 g L 0.1% and distilled water were include as control. Each treatment consisted of five replications. Mortality of the larvae and antifeedant activity were analyzed using analysis of variance, followed by probit analysis for calculating LC 50Â and LT 50-1. The results showed that CLO at 2.0% concentration was the most effective with regard to larvicidal and antifeedant activities. The LC 50 of CLO was 0.09% with LT 24.6 hours. This study revealed that the environmentally friendly CLO can be used as an alternative to synthetic insecticide for control S. litura.
