Metabolic changes in Siam weed, Chromolaena odorata induced by feeding of weed killer, Pareuchaetes pseudoinsulata (Arctiidae: Lepidoptera)



Metabolic changes in Siam weed, Chromolaena odorata induced by feeding of weed killer, Pareuchaetes pseudoinsulata (Arctiidae: Lepidoptera)



Journal of Tropical Agriculture 39(1): 35-37



The arctiid caterpillar, P. pseudoinsulata, has been identified as a potential biological control agent of the Siam weed, Chromolaena odorata. The present study was conducted to assess the metabolic changes in plants induced by larval feeding. The total nitrogen content in leaf samples showed significant variations on 4th, 6th, 8th, 10th, 12th, and 15th days after releasing a variable number of P. pseudoinsulata larvae.
