The pecan agroecosystem is one the most important native tree crops in the United States. Many insects attack the trees, leaves, nuts, buds and are damaged by a wide variety of insects that lower the crop production. Natural enemies such as spiders may help to balance pest population densities in this agroecosystem, therefore they should be considered an integral part of pest management programs in Texas pecans. This website has been designed to help growers and biologists identify common spiders found in pecans and to help understand the role this eight legged group may play in biological control of pests in this crop.

Collections were made in several pecan orchards over a period of three years in Texas, mainly at Robertson Co and Comanche Co. Specimens were collected by using different sampling techniques (pitfall traps, corrugated cardboard bands, fogging sampling, direct sampling).

This project is currently led by the Pecan Insect Lab, Department of Entomology at Texas A&M University.
