AbstractWandering of Cryptolestes ferrugineus (Stephens) larvae was demonstrated in the laboratory among wheat kernels at 30 °C and 15.5% moisture content, initially infested at an adult density of 0.4 adult per gram of wheat. The majority of the wandering larvae were first (37.3%) and fourth (56.0%) instars.

A dockage tester (Carter dockage tester, Hart-Carter Co., Minneapolis, MN) was set up to clean wheat in accordance to Canadian grain industry guidelines and several running conditions. Under all conditions, 84–91% of adults and 57–81% of larvae of the rusty grain beetle, Cryptolestes ferrugineus (Stephens) (Coleoptera: Cucujidae) were recovered from infested 1-kg samples in the aspirator discharge pan. All immature insects implanted in the germ of wheat kernels remained within the kernels, and were found within the bulk of the cleaned whole wheat. It is therefore possible to monitor the aspirator discharge pan of cleaned wheat samples for rapid detection of most free-living C. ferrugineus to limit infested grain from entering primary elevators. Key words: Cryptolestes, detection, dockage tester, Insecta, rusty grain beetle, wheat

The weights and caloric values of insects and exuviae, the food consumed and egested, and oxygen respired were estimated at regular intervals for all stages of the rusty grain beetle, Cryptolestes ferrugineus, reared on wheat kernels. Immature stages assimilated between 66 and 79% of the food consumed and the proportion of assimilated energy converted into tissue growth increased from 3 to 23% during development. Similar observations were made for the lesser grain borer, Rhyzopertha dominica, but the food consumed and egested was not measured because much of the kernel chewed by this insect was not ingested, leaving a frass of white powder difficult to separate from the rejecta. For R. dominica a maximum of 38% of the energy assimilated during development was converted into tissue. Adults of both species used most energy to produce eggs. The net efficiencies of the use of energy for reproduction are higher in some stored-product beetles whose populations increase more rapidly than those which increase more slowly.
