Gamma radiation sensitivity of larvae and adults of the red flour beetle, Tribolium castaneum Herbst

Abstract

In this study, the susceptibility of larvae and adults of Tribolium castaneum (Herbst) to gamma radiation was investigated in the laboratory in Turkey. Gamma radiation was applied at 6 dose levels between 20 and 200 Gy to 13-15 day-old adults and at 5 dose levels between 20 and 180 Gy to 18-20 day-old larvae of T. castaneum. All experiments were performed in growth chambers maintained at 27 ± 1°C and 70 ± 5 % r.h. The larvae proved to be the more susceptible stage, survival to the adult stage being prevented by exposure of the eggs to 100 Gy; the adult stage was less susceptible. LD 50 and LD 99 values were determined as 19,75 and 42,97 Gy for larvae and 33,21 and 64,50 Gy for adult stage, respectively. It was concluded that 100 Gy is the effective dose for both larval and adult stages.

Impact of plasma irradiation on Tribolium castaneum

“…Similar responses were observed by Ferreira et al (2016) on D. melanogaster larvae who reported that the effect of plasma on larval death might be extreme oxidative stress due to ROS, as well as the melanization caused by the activation of the immune system. The various responses to radiation treatment of T. castaneum stages observed in our study were also obtained by Tunçbilek et al (2003) in response to gamma rays, who found that the larvae were more susceptible than the adult stage. Also, Sileem et al (2017) observed that the adult stage of Oryzaephilus surinamensis exposed to low doses of gamma radiation resulted in less sterility than those previously irradiated as larvae, while the irradiated pupae showed the highest sterility.…”

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.…”

Ionizing Radiation and the Influence of Package to Control of Sitophilus Oryzae in Rice

“…This results are similar with others authors to rice weevil and other stored product insects that may require much higher doses, in the range of 1.0 -3.0 kGy (Darfour et al, 2012;Ignatowicz, 2004;Khaghani et al, 2010;Tuncbilek et al, 2003).…”

“…Various authors applied doses to prevent reproduction of stored product pests, including S. oryzae (Hoedaya et al, 1973;Ignatowicz, 2004;Tilton et al, 1966;Tuncbilek, 1995;Arthur, 2003 Arthur andArthur, 2004;Follet et al, 2013). Follett et al, (2013) in dose-response tests to post-harvest using radiation treatment to S. oryzae, infest with adult or immature weevils in the doses of 30, 60, 90 and 120 Gy.…”
