Effect of Gamma Radiation on Growth and Development of Rust Red Flour Beetle Tribolium Castaneum (Herbst.)

Abstract

Study on the sterilizing and lethal effects of Cobalt-60 gamma radiation on the larval and adult stages of rust red flour beetle Tribolium 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.

Efficiency of the Gamma Irradiation in Controlling the Red Flour Beetles, Tribolium castaneum Herbst, and Preventing Its Secondary Infestations

“…The highest dose (1000 Gy) was capable of killing all tested stages, approximately introduced (100 % mortality) throughout the period of examination. The present findings corroborate with those of (Tuncbilek et al, 2003;Tandon et al, 2009;Kabbashi et al, 2012) who reported that the mortality of irradiated Tribolium sp. was augmented as the irradiation dose increased.…”

“…Owing to the huge restrictions on the methods available for the control of stored product pests, alternative methods are required. Gamma irradiation is an effective strategy against this pest as it causes mortality beside sterility in insects depending on the dose and the stage, which was exposed (Warchalewski et al, 2000;Tandon et al, 2009;Abbas & Nouraddin, 2011;Kabbashi et al, 2012). The present study aims to shed a light onto using some doses of gamma-irradiation (which already used for extending the shelf life of wheat flour) to avoid the T. castaneum infestation and subsequently, its Quinones secretion that naturally occurred in infested wheat flour has been avoided.…”

Validation of low dosages of γ-radiation and their effect on red beetle mortality, storability characteristics, and nutritional value of sorghum (Sorghum bicolor L. Moench) grain

“…Similarly, the results are compared with those conducted by many researchers ( Tandon et al, 2009 , El-Naggar and Mikhaiel, 2011 ), that concluded that death of the adult T. castaneum has been induced significantly by gamma radiation of dose not>1.0 kGy. It was stated that many factors influenced gamma irradiation’s impacts on insect mortality.…”

Gamma Radiation: An Eco-Friendly Control Method for the Rice Weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae)

“…Brown et al [ 47 ] found that 0.01 kGy was sufficient to cause sterility in adults of S. granarius . The gamma radiation at 0.07 kGy caused complete sterility in T. castaneum [ 48 ]. For three days, old S. granarius adults could not produce progeny when treated with a dosage of 0.10 kGy or above [ 49 ].…”
