AbstractKnockdown and mortality of adults of the red flour beetle, Tribolium castaneum (Herbst) and the confused flour beetle, Tribolium confusum Jacquelin du Val, were assessed after exposure to two contact insecticides, chlorfenapyr and cyfluthrin, on a concrete surface. Individuals were rated on a scale for knockdown of exposed adults according to their mobility from 1, representing immobilized adults to 5, representing normally moving (similar to the controls). Only cyfluthrin gave immediate knockdown. Adults were rated at 1, 3 and 7 days post-exposure. After the final assessment, adults were discarded and the same procedure was repeated for 5 consecutive weeks with new adults exposed on the same treated surfaces. Despite initial knockdown, many individuals did not eventually die after exposure to cyfluthrin. In contrast, adults exposed to chlorfenapyr were not initially knocked down after exposure but most died after 7 days. These trends were similar during the entire 5-week residual testing period. The storage of the treated dishes in illuminated or non-illuminated conditions did not affect the insecticidal effect of either insecticide. The results of the present study can be further implemented towards the design of a “lethality index” that can serve as a quick indicator of knockdown and mortality rates caused after exposure to insecticides.

Effect of Gamma Radiation on Growth and Development of Rust Red Flour BeetleTribolium Castaneum(Herbst.)Study on the sterilizing and lethal effects of Cobalt-60 gamma radiation on the larval and adult stages of rust red flour beetleTribolium castaneum(Herbst.) was done at 0, 10, 30, 50, 70, 100, 150, 300 and 500 gray (Gy). Irradiation severely affected pupal period, pupal formation and survivability of larvae and adults. The developmental period of the pest was found to increase along with the increase in the radiation doses. The irradiation at 70 Gy was found to cause complete sterility in the insect.

Storage Pest

Gamma radiation effects on the gonads of Tribolium castaneum were assessed by cytological techniques. Pupal treatments of 15 Gy resulted in the significant reduction of testes and ovaries leading to sterility in males and infecundity in females, respectively. The present findings thus provide an important information for designing a sterile male technique for this storage pest species.
