Abstract

The behavioral responses of Asian corn borer (ACB) larvae and adult oviposition, effect on development, fecundity, hatchability of eggs and longevity to the brown seaweed, Sargassum cinctum J. Agardh, was studied to elucidate the mechanism for reduced ACB populations in corn (Zea mays L.) with brown seaweed hanged on the plant as practiced by farmers. The study was conducted from September to December 2015 at the National Crop Protection Center, College of Agriculture, University of the Philippines Los Baños. The methods included rearing pan and Petri plate bioassays to determine possible effects of volatile organic chemicals (VOCs) emitted by brown seaweed. Our results demonstrated that neonates and second instar larvae were apparently repelled by VOCs emitted by S. cinctum. VOCs did not affect significantly larval development, post developmental periods, fecundity and longevity of adult male and female O. furnacalis. Egg hatchability and larval survival were likewise not significantly affected by VOCs from the brown seaweed.
