Impact of Short-Term Atmospheric Heat Transfer on the Survival of Granary Weevil in Stored Winter Wheat

The granary weevil Sitophilus granarius L. is a pest causing substantial damage to stored wheat worldwide, against which the elaboration of sustainable control methods has recently been gaining importance. Our objective was assess efficacy rapid atmospheric convection heat transfer method S. under laboratory conditions. We examined changes in adult mortality and progeny survival triggered by effect this on quality parameters treated items. insecticidal efficacy, achieved treatment infested grains, also analyzed at 37, 47, 67, 87, 107 °C for 5, 6, 7 min 40% 60% rh exposure heating with production assessed 45 days after treatment. were germination test NIR grain analysis. findings showed that adequate eradication obtained 5 suboptimal (40% rh) relative humidity values. At humidity, averages more dispersed, efficacies above expected 95% occurred over longer exposures. progeny-suppression from short-term affirmed. method, applied temperature time combinations, did not induce detectable or ability wheat. Overall, our indicated use post-harvest protection cereals feasible, may contribute realization residuum-free management provide an effective technique integrated management.
