“…Likewise a strain of T. castaneum resistant to DDT and malathion and a susceptible strain were both reduced to Ϸ31% of reproduction when irradiated with 20 Gy (Brower 1974). Phosphine-resistant T. castaneum was signiÞcantly more tolerant than a susceptible strain when measured as adult emergence from irradiated larvae (Nakakita et al 1985); there was no difference between the two strains regarding reproduction of irradiated adults.…”

Phytosanitary irradiation (PI) treatments are promising measures to overcome quarantine barriers to trade and are currently used in several countries. Although PI has advantages compared with other treatments one disadvantage bedevils research, approval, and application: organisms may remain alive after importation. Although this does not preclude their use as a phytosanitary treatment, it does leave the treatment without an independent verification of efficacy and places a greater burden for assuring quarantine security on the research supporting the treatment. This article analyses several factors that have been hypothesized to affect PI efficacy: low oxygen, pest stage, host, dose rate, and temperature. Of these factors, the first is known to affect efficacy, whereas host and dose rate probably need more research. The International Plant Protection Convention considered several PI treatments for its international standard on phytosanitary treatments and did not approve some at first because of perceived problems with the research or the presence of live adults after irradiation. Based on these concerns recommendations for research and dealing with the issue of live adults postirradiation are given. Generic PI treatments are suggested.

“…However, there are a few accounts of radiation susceptibility of some insecticide and fumigant-resistant strains of insect pests of stored products. Brower (1974), working with DDT and malathion-resistant T. castaneum, reported that the resistant strains did not show greater resistance to gamma radiation compared with the susceptible strain. Bhatia and Sethi (1978) reported that resistance to lindane, DDT and Malathion in T. castaneum did not involve any serious change in the susceptibility to gamma radiation.…”

“…Several authors reported no significant change in susceptibility to gamma radiation between the susceptible and insecticide-resistant strains of stored-products insects (Brower, 1973(Brower, , 1974Bhatia and Sethi, 1978;Saxena and Bhatia, 1981). However, Erdman (1966) showed that a strain of the red flour beetle, Tribolium castaneum (Herbst), that was somewhat resistant to DDT compared with a wild type strain, was more radiosensitive.…”

Abs tract. Gamma radiation susceptibility of adults of the fenvalerateresistant strain of Tribolium castaneum (Herbst) (Coleoptera : Tenebrionidae) was studied under laboratory conditions. Selection for resistance to fenvalerate in adult beetles was carried out up to the sixth generation. In each generation of selection, adults of the fenvalerateresistant strain were evaluated for susceptibility to gamma radiation and compared with their fenvalerate-susceptible counterparts. Susceptibility to 60 Co gamma radiation was evaluated on the basis of dosage-mortality (LD50) and time-mortality (LT50) responses. We found the LD50 values for the fenvalerate-resistant and -susceptible strains to be 89.16 and 97.46 Gy respectively, showing no significant difference in susceptibility to gamma radiation. LT50 values were 7.58 and 17.20 days for the fenvalerate-resistant and -susceptible strains respectively, showing that mortality in the resistant strain occurred markedly earlier than in the susceptible strain.

“…Several studies have compared the fitness of susceptible and resistant strains of these stored product pests. For example, Brower (1974) found that a strain of T. castaneum resistant to both malathion and DDT produced significantly fewer progeny than did the susceptible strain. In contrast, Beeman and Nanis (1986) inserted the malathion resistance gene of T. castaneum, Rmal-1, into a susceptible background by repeated backcrosses and found no differences when they monitored the change in the frequency of Rmal-1 in the absence of insecticide.…”

Three factors contributing to fitness of a species (fertility, fecundity, and development time) were measured in the susceptible Savlab strain and the > 100-fold malathion-resistant Statesboro strain of the Indianmeal moth, Plodia interpunctella (Hübner). Both fertility (percent egg hatch) and fecundity (eggs/female) were significantly lower in the resistant strain. Percent egg hatch in the two strains was 96.2% and 73.1% for Savlab and Statesboro respectively. Fecundity was 444 eggs/female for Savlab and 321 eggs/female for Statesboro. Development time did not differ significantly (24.2 ± 0.3 and 23.6 ± 0.2 days for 50% emergence). There was no evidence that these differences arose from non-lethal effects caused by malathion treatment to maintain resistance in the Statesboro strain. The differences, while associated with malathion resistance, cannot be unequivocally attributed to the presence of the resistance gene. When the intrinsic rate of increase (rm) was calculated using an iterative computer program, Statesboro had a significantly lower rate (0.1734 ± 0.0016) than did Savlab (0.2048 ± 0.0014). Similar measurements were performed with progeny from reciprocal F1 crosses. While some parameter's values were closer to Statesboro or Savlab an apparent mating incompatibility suggests that using the data from F1 crosses is premature until this question is resolved.
