Abstract:A prototype treatment chamber for application of high temperature alone or with controlled atmospheres was designed and tested for disinfesting walnut fruit of diapausing larva of the codling moth, Cyndia Pomona ella (L.). All treatments were made at 43°C with air, 0.5% oxygen(in nitrogen), or 98% carbon dioxide (balance air). Earlier in vitro laboratory research. at 43°C, provided exposure time estimate for 95% mortality of 45.2 h for air, 14.6 h for 0.5% O2. and 5.2 h for 98%CO2, Treatment of diapausing codling moth larva within walnut under these conditions in the prototype chamber resulted in mortalities of 97.6% for air,96.1% for 0.5% O2, and 97.6% for CO2, Surviving larvae were moribund and subsequently died.
