Agents for Biological Control of Purple Nutsedge, 'Cyperus rotundus' L. The Genus 'Bactra' Stephens (Lepidoptera:Tortricidae:Olethreutinae) as a Major Source, with Emphasis on the Biology and Potential Use of 'Bactra verutana' Zeller

摘要

The publication surveys insects known to attack purple nutsedge, a worldwide noxious weed; summarizes done on host-plant specificity; discusses broadly the genus Bactra as a major source of insects that limit their attack to purple nutsedge; and focuses on Bactra verutana Zeller as a promising candidate for augmentation releases. The publication details studies done with B. verutana to determine its distribution, its host plants with and without stress, its biology, and ways to increase its effectiveness as a pest control agent.
