【 摘 要 】

 Controlled atmosphere is efficient way to control of stored-product insects. 1,8-Cineole as main component of Eucalyptus spp. has high toxicity on insects. Toxicity of 1,8-Cineole at low pressure was performed against two most common stored-product insects, Callosobruchus maculatus (F.) and Tribolium Castaneum (Herbst) in two time, at three different pressure (Normal pressure, 100 mm Hg, 150 mm Hg). LD50 values of 1,8-Cineole fumigant toxicity in 12 h and 24 h for C. maculatus and T. Castaneum innormal atmosphere pressure of Urmia (Iran) (653 mm Hg) were 275.6, 201.5, 452.2 and 265.1 µl/l air, respectively. LD50 values of 1,8-Cineole fumigant toxicity plus reduced atmosphere pressure in 100 mm Hg, in 12 & 24 h for mentioned insects were 193.5, 118.3, 331.7 and 176.8 µl/l air, and in 150 mm Hg were 210.3, 151.5, 381.4 and 214.7 µl/l air, respectively. Results have been shown that insects susceptibility to 1,8-Cineole, had significant enhancement by reduction in pressure of atmosphere. Toxicity of 1,8-Cineole at reduced pressures was strongly influenced by ambient time. Application of integrated management by essential oils and physical practices such as reduced atmosphere pressure has potential efficacy for stored-product pests control
