Abstract:The importance of trap placement for the detection of adult screwworms, Cochliomyia hominivorax (Coquerel), was studied near Tuxtla Gutierrez, Chiapas, Mexico, during the period August through November 1984. Collections from traps located in woods and suspended below isolated trees and tripods in an open pasture were analyzed for differences. x2 analysis indicated traps within pastures collected significantly more sterile released flies than traps located in woods. In pastures, traps suspended below isolated trees collected significantly more flies than traps below tripods. Males and females exhibited the same recapture patterns. Collections of unmarked C. hominivorax and other fly species exhibited the same capture patterns as marked flies. During periods when trees and other vegetation are in full foliage, detection and survey of adult populations of screwworms may be better accomplished by placing traps in pastures rather than woods. Increased efficiency also may be achieved by suspending traps from isolated trees rather than tripods in pastures.
