Effects of flameless catalytic infrared radiation on Sitophilus oryzae (L.) life stages

► A bench top flameless catalytic infrared emitter, fueled by propane, was evaluated for its ability to kill eggs, larvae of different ages, pupae, and adults of the rice weevil, Sitophilus oryzae (L.), in hard red winter wheat. ► Wheat (113.5 g or 227.0 g) was exposed for 45 or 60 s at an emitter distance of 8.0 or 12.7 cm. ► Temperatures were measured continuously with an infrared thermometer connected to a computer. ► All life stages were completely killed when 113.5 g of wheat was exposed for 60 s at an emitter distance of 8.0 cm.
