Insects for Biological Control of Aquatic Plants.

Abstract

Sameodes albiguttalis (Warren) is a pyralid moth currently under study for the biological control of waterhyacinth (Eichhornia crassipes (Mart.) Solms-Laubach). The objectives of these studies are to: (a) establish field populations of this insect, (b) estimate its vagility, and (c) determine its efficacy in controlling the target weed. Progress made in realizing these objective includes: (a) the establishment of a greenhouse colony as a stock for field releases and (b) the actual release of several hundred insects. To date, 1477 infested waterhyacinth plants have been transplanted to three sites as well as 37 adult insects and 154 first instar larvae. It is still too soon to ascertain the success or failure of these releases and successive releases are continuing. (Author)
