Attraction of Mexican fruit flies (Diptera: Tephritidae) to two synthetic lures: effects of water and thermal stress
2006
Robacker, D.C.
Experiments were conducted in a flight chamber in a controlled-environment greenhouse to determine if thermal and water stress differentially affects attraction of Mexican fruit flies, Anastrepha ludens (Loew), to BioLure MFF 2-component lures and AFF lures. For most combinations of air temperature, water vs. no water in traps, and non-thirsty vs. thirsty flies, responses to traps with BioLures or AFF lures were equal. Generally, higher temperatures, water deprivation of flies, and especially presence of water in traps, increased attraction to both lures. Results indicate that observed greater attractiveness of BioLures compared with AFF lures in Multi-Lure traps in the field is not due to water in traps or thermal stress. Results are consistent with observed greater attractiveness of Multi-Lure traps containing water compared with sticky traps under hot, dry field conditions.
