Botanical insecticides, Melia azedarach, Scirpophaga incertulas, seed extract
Botanical insecticide can reduce the negative impacts of using synthetic insecticide to the environment and human health. One of the potential plants to be developed as a source of ecologically friendly of insecticides is Melia azedarach (Meliaceae). Stem Borer is the major pest of rice crop in Indonesia and its control depend on synthetic insecticide. This study was conducted to evaluate the effects of M. azedarach methanol seed extract on mortality and food consumption of Scirpophaga incertulas. The toxicity test in order to know its LC50 and LC95 value was conducted with experimental method by using Completely Randomized Design which consisted of six treatments and each treatment was replicated three times_ This research was evaluated against the third-instar larvae S. incertulas by dipping method on the pieces of paddy stem at concentration of 0.05%; 0.12%; 0.28%; 0.68%; 1.63% and control. Result of this research indicated that methanolic seed extract of M. azedarach had insecticidal activity with LC50 at concentration of 0.31% and LC95 at concentration of 3,18% in 96 hours after treatment. The treatments at concentration of 0.12%; 0.28%; 0.68% and 1.63%, reduced the number of food consumption of 25.43%; 28.21%; 22.55% and 13.39%. Methanolic seed extract of M. azedarach at concentration of 3.18% (equivalent to LC95) and 6,35% (equivalent to 2 x LC95) did not caused phytotoxic to paddy.
