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.

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.

Residual Film

The chloroform extracts of coriander (Coriandrum sativum L.), ajowain (Trachyspermum ammi (L.) Link.) and fenugreek (Trigonella foenum-grecum L.) were tested against the red flour beetle, Tribolium castaneum (Hbst.) adults through residual film assay and their repellent activity were also conducted. The LD50 values for coriander, ajowain and fenugreek were 316.173 and 243.5895, 271.4573 and 232.7095, and 159.0106 and 4.194236 ?g/cm2 for 24- and 48 h of exposure respectively. According to the intensity of activity the toxicity were found in the order of fenugreek> ajowain >coriander, while the repellent activities were in the order of fenugreek> coriander> ajowain.

Latent Effects

The efficacy of different concentrations of the commercial neem-based insecticide, Nimbicidine® was evaluated against the eggs of the red flour beetle Tribolium castaneum (Herbst). The insecticide significantly inhibited the hatching, pupation and adult emergence of the beetle. The latent effects of Nimbicidine® on the next generation progenies were expressed by significant reductions in the growth of larvae, pupation and adult emergence coupled with lengthened developmental period, but the sex ratio was unaffected.
