Rearing Temperature

The temperature at which an insect has been reared or maintained for considerable time before treatment may affect its susceptibility to insecticides. The susceptibility of the beetles Tribolitim confnsum and Sitophilus granarins to the fumigant carbon disulfide is decreased with the rearing temperature when they were reared at 25,30, and 35°C. Tolerance of DDT was greatest in American cockroaches preconditioned at the lower temperature when they were kept at different temperatures ranging from 17°C to 32°C. In this case, it was proposed that at the lower temperature, lipids tend to be more unsaturated,
