Light traps as detection devices for moths of cabbage looper and bollworm
In a 1966 test, blacklight insect traps effectively trapped moths of cabbage looper and bollworm in a Fresno County cotton field. Increased collections of moths in the traps were followed by a rise in egg and larval populations in the field. Light trap information used together with established field-checking procedures can aid in determining the need for control measures of these pests. More detailed information is available in Leaflet 197, “Light Traps and Moth Identification,” available at local Farm Advisor offices.
