'Vogtia malloi', A Newly Introduced Pyralid (Lepidoptera) for the Control of Alligatorweed in the United States.
Abstract
Vogtia malloi pastrana was introduced into the United States in the spring of 1971 as a biological control agent of alligatorweed, Alternanthera philoxeroides (mart.) Griseb. Vogtia populations were established and survived the winter as far north as Columbia, S. C., and as far south as Fort Lauderdale, Florida. Studies reported herein include: a canonical analysis which describes the insect-host plant relationship between two insects and alligatorweed, the relationship between nutrient levels and alligatorweed growth, and a comparison of alligatorweed growing in lakes and in streams; a multivariate regression analysis which measures the significance of each of 12 measured variables in influencing the growth and spread of alligatorweed. Also included are measurements of alligatorweed productivity in greenhouse studies and in field plot studies during the spring and summer growth periods.
