In New Mexico insect pests can often be well controlled by a combination of insect and spider predators and desiccation from low relative humidity and high temperatures. Our goals are to manage insect pests using our naturally available controls as much as possible only using insecticides when those natural controls are insufficient.In the next five years we will examine the impact of these effects in various crops and under different managent practices. For example we will evaluate okra leaf cotton varieties in an effort to develop management strategies to suppress insect pests in this non transgenic cotton which could be an alternative to Bt cottons that are steadily becoming less effective.We will also determine the key predators of pecan weevil which is an invasive insect that can sometimes be eradicated but will not likely be eradicated from NM counties that border Texas. Suppression of pecan nut casebearer by predators can provide very high levels of control but we don’t know which predators might be able to feed on pecan weevil. Direct observations and motion detector cameras focused on frozen beetles will be used to determine our key predators so we can try to maximize their impact.In alfalfa we will work on biological control of alfalfa weevil which has become an increasingly important pest in the last ten years. Control by parasitoids released by USDA in the 1980s is very variable and we will work on determining the best route to moving and establishing parasitoids in areas where there is little control. We will also evaluate the impact of alfalfa providing beneficial arthropod predators to nearby crops, providing protection to alfalfa growers who usually farm multiple crops.These results are used to make recommendations to growers to use as part of an IPM system to keep insect pests suppressed in an effort to avoid insecticide applications while protecting yields and profits
