V. aEffect of toxic baits used for fruit fly control against Trichogramma pretiosum and Chrysoperla externa.h[electronic resource] c2019 aToxic 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 selected baits on Trichogramma pretiosum and Chrysoperla externa, which are important as biological control agents of fruit pests, was evaluated. Materials and methods ? Bioassays were conducted under laboratory conditions (temperature of 25±2 °C, relative humidity 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 mortality for C. externa, the baits were grouped in the IOBC toxicity categories. Results and discussion ? The malathion- based baits composed by the attractants sugarcane 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 insecticide spinosad added, and the commercial bait Success ® 0.02 CB are harmful to T. pretiosum, with reductions on parasitism capacity higher than 87%. However, these baits are relatively selective to C. externa adults, with mortality ranging from 23 to 60%. Conclusion ? 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. abiological pest control aBrazil afood attractants afruit flies management1 aPASINI, R.1 aGRÜTZMACHER, A.
