AbstractInvestigations were conducted to quantify the effects of treatment of cracked wheat, Triticum aestivum L. (Gramineae), kernels with sublethal and median-lethal concentrations of Bacillus thuringiensis Berliner 1915 (Eubacteriales: Bacillaceae) on the energy use by Plodia interpunctella (Hübner) 1813 and Tribolium castaneum (Herbst) 1797 larvae. Cumulative food consumption and egestion during insect development and the weight and energy values of adult insects were determined and oxygen consumption was estimated. At sublethal (4 μg/g wheat for P. interpunctella, 250 μg/g wheat for T. castaneum) and median-lethal (18 μg/g wheat for P. interpunctella, 1950 μg/g wheat for T. castaneum) concentrations, food consumption during development decreased from controls by 9.1% and 47.1%, respectively, for P. interpunctella and 14.4% and 38.2%, respectively, for T. castaneum. Egestion decreased by 9.5% and 61.5% for P. interpunctella and 19.4% and 47.3% for T. castaneum at these respective concentrations. Increasing B. thuringiensis had negative effects on food consumption and energy use by the insects. Levels of B. thuringiensis lower than required for complete control may assist in protecting grain from stored-product insects.

Resistance to the fumigant phosphine in Tribolium castaneum occurs worldwide. This study evaluated tests based on adult knockdown time, the time for a beetle to become immobile, when exposed to a high concentration of phosphine. We recorded knockdown times of beetles that remained completely still for 30 s when exposed to 3000 ppm of phosphine in a large, gas-tight glass tube. Beetles were used from 12 populations, of which six were ‘susceptible’ to phosphine, three were ‘weakly resistant’, and three were ‘strongly resistant’. Knockdown times were determined for single beetles, as well as for groups of ten beetles for which the time to knockdown for either five beetles (KT50) or ten beetles (KT100) were recorded. Similar knockdown times occurred across susceptible and resistant populations. However, the KT100 tests generated conservative times for diagnosing strong vs. weak resistance. The strong resistant populations were all over 100 min with KT100, compared to 60 min or less for susceptible and weak resistant populations. Special tests on single beetles revealed higher knockdown times in insects that were deliberately disturbed compared to those without any disturbances. Work reported here suggests a knockdown test conducted on beetles in a matter of minutes or hours could help classify phosphine resistance status prior to decisions on phosphine fumigation.
