Population Monitoring of Lygus Hesperus with Female-Baited Traps

John R. McLaughlin


Wing-type sticky traps baited with virgin female Lygus hesperus were placed about a 2.4-ha field of cotton at the Shafter Research Station. Virgin females from 7 to 14-days-old reliably attracted males; attraction occurred in the morning hours; mating of females dramatically reduced attractiveness; trap captures of males mirrored the numbers of males captured by conventional sweep net method; trap captures also indicated the population magnitude in the immediately adjacent area of the field.
