SELECTIVE ATTRACTION OF Vespula germánica (Hymenoptera: Vespidae) TO FEEDING BAITS ENHANCED WITH ISOBUTANOL AND ACETIC ACID

ABSTRACT Vespula germánica (F.) has a negative impact on agriculture, beekeeping, and tourism in Chile. Therefore, environmentally-friendly strategies need to be implemented to control this serious pest. The objective of this study was to evaluate the response of adults of V. germanica to different...

Therefore, environmentally-friendly strategies need to be implemented to control this serious pest. The objective of this study was to evaluate the response of adults of V. germanica to different types of baits with acetic acid + isobutanol (AAIB) added. The selected baits were: blood and bone flour (BF), raspberry jam (RJ), and sweet condensed milk (CM). The trial was conducted in a severely infested site in central Chile. Mixtures were placed in bottle traps. All of the traps were monitored daily from Monday to Friday during 5 weeks, and rebaited every week. A randomized complete block design, with 12 treatments and 4 replicates was used. Captures of V. germanica and other social hymenopterans were identified and data were recorded; V. germanica individuals approaching the trap openings (= visits) were also counted. A number of 15,480 V. germanica individuals, which were mostly workers, were captured. The most attractive baits were CM and BF + 2 mL AAIB. Feeding baits attracted significantly more workers with increasing concentrations of chemicals (AAIB), and significantly more wasps than the feeding baits alone. Lesser captures occurred of Apis mellifera workers (1,046), while the preference trend differed from that observed for V. germanica in several treatments. A number of 854 Polistes buyssoni workers were captured, but no differences were found between treatments. In addition, a number of 466 V. germanica visited the traps, but the trend observed with captures only occurred in traps baited with BF + AAIB, whereas no preference trend was observed for mixtures with RJ and CM.
