“…Insect eggs are expected to be one of the most sensitive stages to irradiation, especially in the early stages ( Bakri et al 2005 ). C. capitata eggs irradiated at 4 h old are more radiosensitive than older eggs and, at this age, doses higher than 20 Gy are sufficient to prevent pupation and adult emergence ( Rahman et al 1990 ). MaCFarlane (1966) observed that 20 Gy was sufficient to prevent egg hatch of Bactrocera tryoni (Froggatt) 2–5-h-old eggs.…”

“…Very few studies have been undertaken to correlate the stage of embryological development with radiosensitivity. Rahman et al (1990) and Jessup et al (1992) showed that the t ganglion (i.e., brain) of C. capitata and Bactrocera spp. was reduced significantly in size when eggs or young larvae (up to 96 h after eggs were laid) were irradiated with doses between 5 and 150 Gy.…”

As the incidence of Anastrepha fraterculus (Wiedemann) has increased in Southern Brazil in the past 3 yr, an initiative to release sterile flies and parasitoids has started. In order to make feasible the mass-rearing of the parasitoid Diachasmimorpha longicaudata (Ashmed), this study investigated the suitability of A. fraterculus larvae derived from irradiated eggs as host for D. longicaudata. Two different ages of A. fraterculus eggs (24 and 48 h old) were analyzed for hatchability after the exposure to a range of radiation doses. The hatchability of 48-h-old eggs was not affected by radiation, and no fly emerged at doses higher than 27.5 Gy. The larvae derived from irradiated eggs proved to be suitable hosts for the parasitoid development, with observed parasitism rates higher than 70% and sex ratio values above 0.6. The parasitism capability and longevity of D. longicaudata reared on larvae derived from irradiated eggs were also assessed. During the 10 d of parasitism evaluated, D. longicaudata from the treatments were able to parasitize nonirradiated larvae similarly as the parasitoids from controls and the laboratory colony. The longevity of D. longicaudata from the treatments was not affected either, with survival rates higher than 80% after 20 d of evaluation. The age of 48 h and a dose of 30 Gy could be considered the best age and dose for A. fraterculus eggs to be used in the mass-rearing of D. longicaudata. The results of this study will decrease the costs of mass-rearing D. longicaudata on A. fraterculus.

“…The low enzyme level in irradiated insects is due to the ability of plasma to suppress PO activity in haemocytes, which implicates possible inhibitors in the irradiation. Moreover, irradiation decreases the size of the supraoesophageal ganglion (Rahman et al, 1990) and this might ultimately lead to a decrease in PO activity (Surisan et al, 2004).…”

Abstract. The effects of different abiotic agents that may modulate the activity of an insect's immune system are reviewed. These agents include insecticides, chitin synthesis inhibitors, juvenile hormone analogues, inert particles, antibiotics, heavy metals, radiation and miscellaneous substances. The significance of studying immunomodulation in insects treated with abiotic agents in relation to both insect control and insect-borne parasitic diseases and the link between immunomodulation in insects post-treatment with both abiotic and biotic agents are discussed.
