Toxic baits are an important tool in fruit flies management; however, some beneficial insects such as natural enemies can be impaired by this technique.
In this study, the toxicity of some se-lected baits on Trichogramma pretiosum and Chrys-operla externa, which are important as biological con-trol agents of fruit pests, was evaluated. Materials and methods ? Bioassays were conducted under labora-tory conditions (temperature of 25±2 °C, relative hu-midity 70±10% and 14 h day length) and consisted on the exposure of adults to a fine film of bait (drops with ~ 4 mm of diameter). Based on either, reduction of the parasitism capacity for T. pretiosum or mortal-ity for C. externa, thebaits were grouped in the IOBC toxicity categories. Results and discussion ? The mal-athion-basedbaits composed by the attractants sug-arcane molasses (7%), Biofruit® (5%) and ANAMED®are harmful to both species based on reduction of >96% in the parasitism capacity of T. pretiosum and 100% mortality for C. externa. Toxic baits composed by the aforementioned attractants with the insecti-cide spinosad added, and the commercial bait Suc-cess® 0.02 CBare harmful to T. pretiosum, with reduc-tions on parasitism capacity higher than 87%. How-ever, these baits are relatively selective to C. externa adults, with mortality ranging from 23 to 60%. Con-clusion ? Based on the obtained results, toxic baits with spinosad are more selective to predators and considered a more ecofriendly option for integrated fruit flies management.KeywordsBrazil, fruit flies management, biological pest control, food attractants MenosToxic baits are an important tool in fruit flies management; however, some beneficial insects such as natural enemies can be impaired by this technique.
