Control of Vespula germanica (Hym. Vespidae) populations using toxic baits: bait attractiveness and pesticide efficacy
Journal of Applied Entomology 131 (9-10), 630-636
Abstract: Our aim was to test a set of baits and pesticides for the control of yellowjacket populations in NW Patagonia (Argentina), through field trials. We tested the attractiveness of protein (fresh and freeze-dried beef) and carbohydrate (corn syrup and honey) baits (alone and mixed) and three pesticides commonly employed to control terrestrial domestic arthropods (hydramethylnon 2%, permethrin 0.3% and chlorpyrifos 0.25%). Our results show that beef proved to be the most attractive bait tested, for Vespula germanica wasps in NW Patagonia. Honey and corn syrup alone or mixed with beef did not attract foraging wasps as did beef-only baits throughout the wasp season. Additionally, we show that the attractiveness of lyophilized beef baits is similar to that of fresh beef. The efficacy of the insecticides tested was limited. In fact, only baiting with hydramethylnon 2% reduced wasp populations (54%) and this occurred after 72 h since poisoning. However, given the potential of insects to develop resistance to a consistent use of a single product (e.g. fipronil 0.1%), the use of hydramethylnon may allow the alternating of insecticides in specific situations. The information provided here contributes to the existent knowledge on baits and insecticides for the control of yellowjackets using toxic baits.
