Abstract
The golden apple snail, Pomacea canaliculata is an invasive alien species that seriously affects rice cultivation in many Asian countries. Due to the toxic hazards of the synthetic insecticides, biological control through botanical pesticides is the best alternative for reducing the golden apple snail damage in paddy fields. Neem or also known as Azadiractha indica was proven to have the molluscicidal potential for controlling golden apple snails. The purposes of this study were to quantify the Azadirachtin content and antifeedants activity of different neem extract for controlling golden apple snail. Azadirachtin content was quantified using UV-visible spectrophotometer. Antifeedant test was conducted with five different concentration of neem seed extract. Methanol extraction with fresh neem seed showed high antifeedant activities compared with other treatments with 81% Feeding Deterrent Index (FDI). Azadirachtin contents in the neem seed extract showed range from 53.36-54.08 ppm for methanol extraction and 52.95-53.97 ppm for water extraction. Based on the finding, the neem seed has the potential to be formulated as biopesticide for management of golden apple snail in the field.
