Eggs, inert deutonymphs and young, virgin adults of Rhizoglyphus echinopus (Fumouze and Robin) and Aleuroglyphus ovatus (Troupeau) were treated with 5, 10, 15, 20, 40, 60, 80, and 100 krad of gamma radiation. Fecundity, egg viability, oviposition period, survival of developmental stages, and longevity of females were compared. Doses ≥ 40 krad completely inhibited egg development. Eggs of A. ovatus were more resistant to gamma radiation than those of R. echinopus. The effect of irradiation on the inert deutonymphs was more detrimental than it was on young adults. Effect of irradiation on the life span of females of both species was stimulatory at doses of up to 60 krad and inhibitory at higher doses. The oviposition period varied inversely with the irradiation dose. Irradiation with 5 krad caused, in both mite species, at least a 50% decrease in fecundity.

Gamma Radiation Sensitivity of Different Stages of Saw-Toothed Grain BeetleOryzaephilus SurinamensisL. (Coleoptera: Silvanidae)The effect of gamma irradiation on different developmental stages ofOryzaephilus surinamensisL., was investigated. Results showed that a required dose to prevent larval emergence from irradiated 1-2-days-old eggs was 60 Gray (Gy), and 350 Gy was required to prevent adult emergence from 15-days-old larvae. Also the required dose of radiation to prevent adult emergence from irradiated 5-days-old pupa was 700 Gy. The dose of 200 Gy caused 100% mortality of irradiated adults 28 days after treatment. In addition, the effect of gamma rays was studied on the developmental stage period of each irradiated stage till adult emergence. The results revealed that there was a dose-dependent increase of the developmental periods. The growth index of adults was significantly decreased with increasing dose of radiation administered to eggs, larvae and pupae. It is recommended that doses between 600 and 700 Gy should be used to control population growth ofO. surinamensiswhen targeting pupae and adults present in stored products.
