Gross Effects of Gamma Radiation on the Indian-Meal Moth and the Angoumois Grain Moth

Effect of sublethal doses of gamma radiation on the fecundity, longevity and sterility of adults of Sitotroga cerealella (Olivier) (Lepidoptera, Gelechiidae)

“…In general, the longevity of females at all doses used was slightly longer than males. These results agree with the findings of Cogburn et al (1966), who stated that the life span of S. cerealella adults was not greatly shortened by doses of 13.2+10%, 17.5, 25.45 and 100 krad. Also, Calderon and Gonen (1971), in their studies on E. cautella adults, came to the same conclusions.…”

“…Increasing the dosage to 24 krad resulted in further reduction in egg hatching to 1.75% and caused 98.14% sterility (the respective percentages in the opposite irradiating (Table 4). These results are in agreement with those of Cogburn et al (1966), who concluded that the incidence of sterility in S. cerealella and P. interpunctella adults treated with 17.5 up to 100 krad of gamma radiation varied directly with the dosage applied. Also, Calderon and Gonen (1971), in their studies on E. cautella, came to the same conclusion.…”

“…In continuation of this work, the present paper presents the results of a study carried out on the effect of sublethal doses of gamma radiation on the fecundity, longevity and sterility of its adults, since the method of sterilizing the adults appear to offer greater promise than trying to use lethal doses. Similar studies were carried out on other species of stored-product insects; examples of which are Pesson (1963), Cogburn et al (1966), Calderon and Gonen (1971) and Brower and Tilton (1973).…”

Genetic Control of Insect Populations

“…The delayed effect from irradiation of Lepidoptera was first observed by Proverbs and Newton (56) on Laspeyresia poinonella and then again by Husseiny and Madsen (57) in Paramyelois transitella and by Cogburn et al (58) in Sitotroga cerealella. The work of Bauer (31) led to the discovery of the chromosomal basis of this effect by Walker and Quintana (59) working with Diatraea saccharalis and by North and Holt (60) working with Trichoplusia ni.…”
