Heliothis Resistance Monitoring and Methods

J. W. Mullins, C. A. Staetz


Pest susceptibility to available pesticides is an extremely valuable but limited resource. Various tactics are now being developed and implemented to preserve susceptibility to current and future products. However, regardless of the program developed, monitoring data is absolutely necessary to determine if pest susceptibility is changing. It is only through continual susceptibility monitoring that the effectiveness of a particular management program can be assessed because changes in susceptibility are not always directly reflected by field control. Currently, there are several test methods being utilized to monitor cotton pest susceptibility changes. These include the adult vial test (AVT),.foliar tests, topical tests and, to a limited extent, biochemical and electrophysiolgical tests.
