COTTON APHID (HOMOPTERA:APHIDIDAE) TREATMENT THRESHOLD INCORPORATING NATURAL ENEMIES IN ARKANSAS COTTON

摘要

The objective of this study was to incorporate the action of biological control agents in a treatment threshold for the cotton aphid, Aphis gossypii Glover. The primary means of managing the cotton aphid, Aphis gossypii Glover, is through applicationof insecticides based on treatment thresholds that fail to take into account the pest's natural enemies. Currently, treatment thresholds in Arkansas rely only on the percentage of infested plants when aphid populations are increasing. The objective of this study is to incorporate the use of beneficial insects and the entomopathogenic aphid fungus, Neozygites fresenii, into the decision making process for managing cotton aphid. The use of natural enemies in making treatment decisions is underutilized inrow-crop agriculture.
