Using Buffer Crops to Mitiigate Lygus Migration in San Joaquin Valley Cotton

P.B. Goodell and J.W. Eckert


Blackeye beans (Vigna sinensis) were evaluated for its host preference by Lygus hesperus. Two years of replicated, small plot field trials indicated Lygus preferred blackeye beans over cotton for reproduction and residency. A field demonstration was established in 1997 on a commercial scale in which a strip of blackeye beans was placed on the edge of a cotton field. The beans resulted in higher Lygus populations then cotton but adjacent cotton was not threatened with excessive fruit loss. These trials demonstrated the practicality and value of buffer or catch crops in mitigating Lygus migration.
