Abstract
‘Hass’ avocados were infested artificially with immature life stages of Queensland fruit fly, Bactrocera tryoni syn Dacus tryoni (Froggatt), dipped for 3 min in 500 ppm benomyl at 46°C, allowed to dry, and stored at 1.0 ± 0.2°C. Dose-mortality data from infested fruit held in cold storage for up to 7 d showed that the third instars were the most tolerant to treatment. None of >200,000 third instars infesting ‘Hass’ avocados survived to pupation after hot fungicide dip and storage at 1°C for 15.63 d.Keywords
