“…Elbadry (1965) suggested that moths eggs exposed to gamma radiation could serve as a food resource for Trichogramma rearing. Examining the acceptability of irradiated moth's eggs to parasite development showed that irradiated eggs were as suitable as control ones (Marston and Ertle 1969;Fatima et al 2002;Saour 2004;Ayvaz et al 2008b). In order to determine the irradiation dose, however, the radiosensitivity of the eggs has to be investigated.…”

“…Due to its weak penetrating power, however, eggs have to be treated in a very thin layer which may limit its applications, or high quality, more expensive machines are to be used. Ionizing radiation, particularly gamma radiation, has a very high penetrating ability and has been used for killing insect eggs before (Brower 1982;Tilton and Brower 1983;Toba and Burditt 1992;Mansour 2004;Ayvas and Tuncbileck 2006;Ayvaz et al 2008b).

The sensitivity of the Mediterranean flour moth, Ephestia kuehniella, eggs in different stages of development to gamma irradiation was studied and the acceptability of irradiated eggs by Trichogramma cacoeciae females was examined. Eggs ranging in age from 1-24 to 49-72 h were exposed, at 24 h intervals, to gamma radiation dosages ranging from 25 to 400 Gy and effects of gamma radiation on egg hatch and adult emergence was investigated. In addition, the developmental rate of immature stages (larvae and pupae), resulting from irradiated eggs, to the adult stage was examined and the acceptance of irradiated eggs to T. cacoeciae females was evaluated. Results showed that the radio-sensitivity of E. kuehniella eggs decreased with increasing age. Egg hatch in 1-24-h-old eggs was significantly affected at 25 Gy dose and at 75 Gy dose, no egg hatch was observed. When irradiating 25-48-h-old eggs, however, egg hatch was less than 5% at 100 Gy dose, and eggs 49-72-h-old were more resistant; 50 Gy had no significant effect on egg hatch and 300 Gy did not completely prevent it. Irradiation also negatively affected survival to the adult stage. When 25-48-h-old eggs were irradiated, survival to the adult stage was completely prevented at 75 Gy dose and no survival was observed beyond 100 Gy dose in 49-72-h-old eggs. In addition, the rate of development of immature stages resulting from irradiated eggs was negatively affected. While more than 97% of control moths emerged within 30 days, this ratio decreased to 53 and 69% in 1-24 and 25-48-h-old eggs exposed to 25 Gy dose. Furthermore, irradiation positively affected the degree of acceptance of eggs to parasitization; irradiated eggs (B49-h-old) were more acceptable to T. cacoeciae than cold-treated ones.

The interaction between the entomopathogenic bacterium Bacillus thuringiensis subsp. kurstaki and the entomopathogenic nematode Heterorhabditis bacteriophora (Heterorhabditidae) was examined against larvae of Ephestia kuehniella (Lepidoptera: Pyralidae) at 7, 14, 21 and 28 days post treatment, in laboratory conditions. Three different combinations of the aforementioned pathogens were tested on 4 th instar larvae, namely 500ppm B. thuringiensis subsp. kurstaki (B.t.k.) and H. bacteriophora infective Juveniles (1000IJs/ml), 1500ppm B.t.k. and H. bacteriophora (1000IJs/ml) and 3000ppm B.t.k. and H. bacteriophora (1000IJs/ml). At 7, 14 and 21 days, the interaction between the pathogens was additive in two of the treatments and synergistic in one, whereas at 28 days, it was negative in two of the treatments and synergistic in one. Overall, the application of the lowest dose of B.t.k. (500ppm) in combination with H. bacteriophora (1000IJs/ml), turned out to be highly effective. The interaction between B. thuringiensis and H. bacteriophora is to be further examined.

“…A host of others point to health problems from accidental or deliberate exposure to pesticides. It is therefore imperative to develop safe alternatives that have the potential to replace the toxic fumigants, yet are effective, economical and convenient to use [6]. One of the ways of reducing the continual dependence on imported insecticides is to use the widely available but underutilized plant products.…”

Efficacy of Agave sisalana n-Hexane Extract in the Control of Callosobruchus maculatus (Fabricius) (Colloptera: Bruchidae) Pest

Collosobruchus maculatus is a weevil that has been causing great damage to cowpeas especially in the stores. Therefore, there is need to search for biopesticides that can be used to control the pest rather than using synthetic chemicals. In this work different concentrations of Agave sisilana n-hexane extract were prepared using two-fold dilution at 100, 50, 25, 12.5, 6.25, 3.125 and 1.5625 mg/ml and were used to treat 40 selected beans in different kilner jars. The treated beans were infested with ten (10) identified female and male C. mauculatus each. The result shows that the insect was more killed by the extract at concentration greater than 50 mg/ml. The plant extract was effective against the oviposition and survival of larvae and pupae when compared with the untreated control. In conclusion, the extract of has great potential for use as a plant-based biopesticide for controlling C. maculatus.

Gamma radiation sensitivity of the eggs, larvae and pupae of Indian meal moth Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae)

Abstract: F(1) males from irradiated pupae were more sterile than parental males. To prevent larval emergence from irradiated eggs, a dose of 350 Gy is required. The same dose is required to prevent the larvae from reaching the adult stage.
