ResumoA new standard plastic wet trap was used to collect and preserve various species of yellowjackets attracted to synthetic chemical lure. The trap was used to monitor seasonal differences in the activity of yellowjackets in 4 southern and central California localities. Responsive sympatric yellowjacket species were readily detected, even when some species represented less than 1% of the yellowjackets present. Although more than 0.5 million Vespula pensylvanica (Saussure) were trapped in 3 localized sites, there was no apparent reduction in the intensity of yellowjacket scavenging activity in the trapped areas during the time when traps were exposed.
