Effects of commercial entomopathogen-based formulations on Neoseiulus sp. in pine trees

Biological control is a growing branch in Brazil, and with it comes the need to obtain efficient enemies of pests. The use entomopathogens has expanded investigate their selectivity non-target organisms. present work was conducted pinecone (Annona squamosa L.) orchard objective evaluating which locations plant (lower, middle or upper third) effects entomopathogens: Beauveria bassiana, Metharhizium anisoplie Bacillus thuringiensis on predatory mite. Sixteen weekly applications were made between March August 2017 constant pressure knapsack sprayer, nozzle type JA-2 jet directed at entire plant. treatments consisted three entomopathogenic biological products: Dipel, Beuaveria bassiana JCO Metarhizium anisopliae applied alone combination. Eight performed, as follows: T1-Spraying M. + phfos (Quimifol) adhesive spreader (Agral), T2-Spraying B. T3-Spraying thruringiensis T4-Spraying basisiana T5- Spraying T6- (Agral); T7- (Agral) e T8-Testify, spraying (Agral). results indicate preference Neoseiulus sp. mite for third canopy. obtained indicated that influenced population until sixth week after treatment, where combination one most negatively affected
