There was no significant difference in the total lipid of 1,2-dibromoethane (EDB) resustabt (LWR) and nor (LWN) strain of Sitophilus granarius (L.) of the same weight. The mean total lipid of LWR insects was greater than that of LWN insects because of their greater weight and weight-dependent lipid content. Studies with 14C labeled EDB showed no relationship between insect weight and percentage of total 14C ether extractable after 2 days. Inert storage of EDB in lipid was not a factor in determining the relative strain susceptibility to this fumigant. Lipid was consumed during stress conditions of starving or after fumigation, and a possible role of greater total lipid in increasing endurance or vigor tolerance is discussed.
