“…A previous study showed that the doses of 450 and 300 Gy induced sterility in male and female CLM if irradiated as 5‐day‐old pupae (Osouli & Atapour, 2018). European corn borer parental generation sterility occurred if 5‐day‐old female and male pupae were irradiated with doses higher than 300 and 350 Gy, respectively (Osouli et al, 2020). Our results are congruent with previously reported studies conducted on ECB F1 generation.…”

“…The effect of doses of gamma radiation on the mating competitiveness of the irradiated male (as 5‐day‐old pupae) and F1 male progeny from irradiated male parents in various ratios was evaluated at 1:1:1, 2:1:1, and 5:1:1 (irradiated/F1 male: normal male: normal female, respectively) compared with 0:1:1 and 1:0:1 as controls. Doses of 400 and 350 Gy as almost complete sterility doses of gamma radiation were used for irradiation of male pupae of CLM and ECB, respectively (Osouli & Atapour, 2018; Osouli et al, 2020). The sub‐sterilizing doses of 150 and 200 Gy were also used for irradiation of male parents of CLM, and 90, 120, and 150 Gy for male parents of ECB.…”

“…Our previous studies indicated that doses higher than 300 and 350 Gy would be required for inducing sterility in the female and male of ECB, and 300 and 400 Gy in the female and male of CLM, respectively, whereby few or no progeny is expected from the irradiated pupae (Osouli & Atapour, 2018; Osouli et al, 2020). The objective of the present studies was the evaluation of productive performance and competitive ability of F1 progeny of both lepidopteran species in response to sub‐sterilizing gamma radiation doses.…”

Citrus leafminer (CLM), Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), and European corn borer (ECB), Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), are two key pests of young citrus and maize plants in Iran, respectively. In this study, the effects of sub‐sterilizing doses of gamma radiation (100–250 Gy for CLM, 90–180 Gy for ECB) on the biological and reproductive parameters of F1 progeny from irradiated males were determined. The results indicated that males irradiated at doses of ≥200 and ≥150 Gy produced highly sterile F1 descents for CLM and ECB, respectively. No adverse effects of radiation doses applied to males were observed on the F1 pupal emergence for both species, nor on the adult longevity of male and female ECB moths. However, the life span of CLM F1 male and female adults decreased with increasing doses. The sex ratio of emerged adults of F1 progeny from irradiated males was skewed towards males with increasing doses; the proportion of males to all emerged adults reached 0.52 and 0.54 at doses of 250 and 150 Gy for CLM and ECB, compared to 0.44 and 0.49 in the controls, respectively. The competitiveness index of irradiated and F1 males of both species fluctuated in acceptable ranges and in general F1 males were stronger competitors than their irradiated male parents. The results of the field cage experiments showed that the larval infestation in all cages including the released irradiated CLM and ECB moths decreased compared to the control treatment – the percentage of damaged leaves and stems in the cages with ratios of 20:1 and 7:1 irradiated‐to‐normal insects (highest ratios assayed) reached half and one‐third of the control for CLM and ECB, respectively.

“…Furthermore, Kinipling [10] argues that insect exposure to ionizing radiation sterilizes them by inducing dominant fatal mutations in their genetic makeup that can effectively suppress and eliminate numerous lepidopteran insect pests. Other researches have reported that gamma irradiation induced insect sterility and disturbed the life span of the produced progeny that were in relation to the irradiation doses and the irradiated stage [11][12][13][14] . Therefore, the current research was designed to study the influence of gamma radiation on some biological features of S. frugiperda as alternative clean control tool.…”

The fall armyworm Spodoptera frugiperda (J.E. Smith) is invasive pests in Egypt, and is considered the most important Lepidopteran pest to global agriculture. This study targeted studying the effect of different gamma radiation doses on S. frugiperda, and to evaluate its potential as a control measure. Five-day-old pupae received radiation treatments at dosages of 100, 200, 300 and 400 Gy. The results showed that irradiation with 100, 200, 300 and 400 Gy had no significant effect on male adult emergency (30%, 33%, 23% and 34%), however adult females were further susceptible than males that recorded 37.74%, 28.30%, 29% and 29.33%, respectively. Afterward irradiation with the substerilizing doses of 200 and 300 Gy, there was no egg hatchability. The results showed that, no significant difference among radiation doses of 100, 200 and 300 Gy in total protein and protease enzymes, while the high dose induced highly significant reduction in the activity of alkaline phosphatase and lactate dehydrogenase (LDH). Gamma radiation is hygienic, an efficient and secure physical restraint tool for controlling S. frugiperda, and it can reduce the pest population. It is also highly effective against enzymatic activity of target pests.
