Search, spray for pecan nut casebearers before infestation

Now is the time to check for insects that could infest crops.

The pecan nut casebearer is one of the most important nut-infesting insect pests for pecans, according to news release from the DeWitt County Extension office.

The best way to determine if there is a need to spray for the casebearer is to look for eggs, which are laid on the nutlets soon after pollination, according to the release.

The eggs are white and turn pink as they near hatching, and looking below clusters can show the presence of newly hatched larvae, according to the release.

Depending on the pecan nut load, usually around 5 percent nut entry requires an application of insecticide.
