The obyective of this research was to develop extraction method of active component's neem leaf and examined their bioeffectivity to Plutella xylostella.
Neem leaf extraction was based on polarity of three solvent extracts i.e. methanol-water extract, chloroform-methanol extract and water-methanol extract. Active component's neem leaf of the extracts were analyzed by high performance liquid chromatography (HPLC). Percent reduction feeding (RF) was used to study bioeffectivity of the extracts using pest insect (Plutella xylostella) of tsoisim cabbage leaf.
The results showed, the HPLC analysis of chloroform-methanol extract detected 15 peaks of chromatograme and at methanol-water extract detected 6 peaks. The test results of bioassay showed 40 ppm of chloroform-methanol extract on tsoisim cabbage leaf affected on the consumption of leaf and reduction feeding by insect at 18 and 42 hours after treatment respectively, while 40 ppm of methanol-water extract on tsoisim cabbage leaf affected lower. Highest reduction feeding (% RF) was obtained on 40 ppm chloroform-methanol extract at 18 and 42 hours after treatment. Metamorphoses regulator was obtained when 30 ppm of chloroform-methanol extract was used.
