Biological control of the weed, Chromolaena odorata Asteraceae, Pareuchaetes pseudoinsulata Lep Arctiidae on Guam and the northern Mariona Islands



Biological control of the weed, Chromolaena odorata Asteraceae, Pareuchaetes pseudoinsulata Lep Arctiidae on Guam and the northern Mariona Islands



Entomophaga, 344: 531-539



Chromolaena odorata L. is a major weed of tropical plantations and pasture lands. Pareuchaetes pseudoinsulata Rego Barros Lep.: Arctiidae was mass-reared and released to control the weed on the Mariana Islands of Guam, Rota, Tinian and Saipan in the western Pacific. One year following establishment of P. pseudoinsulata on Guam, the weed was reduced 100% at 3 of 4 sites monitored with fixed quadrants. Seed production was prevented if defoliation occurred prior to the beginning of the flowering season. If defoliation occurred shortly after flowering began, the developing seeds were eaten by P. pseudoinsulata or there was a significant reduction in weight and germination of seeds that matured. Eighteen months after establishing on Guam, P. pseudoinsulata had defoliated appr. 25,000 hectares of the weed. This is the 1st report on the quantitative impact of any control agent for C. odorata, and though the long term effect of the insect is still unknown, these results are encouraging.
