Field, semi‐field and greenhouse testing of HOOK SWD, a SPLAT‐based attract‐and‐kill formulation to manage spotted‐wing drosophila

Abstract Native to Southeast Asia, the spotted‐wing drosophila ( Drosophila suzukii ) has become a major pest of small fruit crops in Americas and Europe because females can oviposit ripening fruit. Currently, D. management relies heavily on chemical control; thus, more sustainable approaches like attract‐and‐kill need be evaluated reduce insecticide use. In previous studies, HOOK SWD, an product that combines attractants, phagostimulants (spinosad), showed promise for still, little is known about its performance under field conditions varying host‐fruit densities, as well residual activity. Here, we efficacy SWD when applied commercial blueberry farms, deployed semifield cages different adult densities aged 30 days greenhouse. Results from experiments could infestation farms; however, varied space time. Semifield cage studies revealed relatively high both adults effectiveness which might explain variation field. Ageing greenhouse at least yielded no significant decrease insecticidal Altogether, these show potentially suppress populations field, but it should used part integrated program instead stand‐alone control tool, especially densities.
