Evaluate the relationship of alfalfa management systems to lygus bug infestation development and to utilization of alfalfa as a biological control agent preserve.
Assess cotton cultivar relationship (plant resistance) to cotton pest infestation development and pest impact on plant development and fruiting.
Evaluate cotton cultivar relationship to pesticide resistance in greenhouse whitefly

PROCEDURES: Predacious Mite Studies. Predatory mites obtained from a commercial insectary were distributed…
