Evaluation of fast neutron irradiation as a new control method against the Indian meal moth, Plodia interpunctella (Hübner)

Abstract

Ionizing radiation is considered a promising treatment for stored product pest management. The dose levels 0, 64, 128, 192, and 256 Gy of Fast Neutron Irradiation (FNI) were tested to determine the lethal dose for preventing the reproduction of Plodia interpunctella. The dose needed to induce sterility in both sexes of adult moths is also evaluated. The results of immature stages irradiation demonstrated that the developmental periods and adult longevity were significantly shorter than the control treatments. Moreover, the reductions of fecundity, fertility, and growth rate were based on the dose of FNI, insect sex, and sage. The results revealed that inherited sterility in F 1 generation was more prevalent in irradiated male pupae than irradiated female pupae and also full grown larvae. The results indicated that the 256 Gy was prevented the development of all immature, thus we could considered it as a lethal dose that use in disinfestation treatment. While, full grown pupae irradiation with 128 Gy was an effective dose that induce adequate sterility of Plodia interpunctella that can use in the sterile insect technique program.

Enhancing Food Grains Storage Systems through Insect Pest Detection and Control Measures for Maize and Beans: Ensuring Food Security Post-COVID-19 Tanzania

“…Various sources of ionizing radiation, such as gamma rays from cobalt-60 and cesium-137, highenergy electrons, X-rays, and UV radiation, are commonly utilized for this purpose in the food industry [128]. In the case of P. interpunctella, [129] discovered that neutron irradiation proved to be an effective means of control. Another promising approach is radiofrequency heating, as demonstrated by [130], which allows for pest control through the application of heat without leaving behind chemical residues.…”

Effect of ultra violet irradiation on life table of Mediterranean flour moth, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae)

“…Arthur et al (2015) stated that UV-rays are generally less harmful to living organisms than the ionizing radiation as they penetrate only the surface layer of cells. A number of investigators have considered the possibility of using UV-rays to control, or at least to suppress the development of various species of stored product insects such as Ephestia kuehniella (Zeller) (Azizoglu et al 2011), Oryzaephilus surinamensis (Linnaeus), Tribolium castaneum (Herbst), Acarus siro (Linnaeus) and Tyrophagus putrescentiae (Schrank) (Collins and Kitchingman 2010), Trichogramma euproctidis (Girault) (Tuncbilek et al 2012) and Sitophilus zeamais (Motschulsky) (Hassan et al 2019).…”

Biological Studies on the Effect of Gamma Radiation and Thermal Treatment on the Angoumois Grain Moth, Sitotroga cerealella (Olivier)

“…it is widely used as disinfestation treatment in many regions. The use of irradiation treatments as disinfestation treatment depends on kill or inhibit the development of immature stages in irradiated products (Ayvaz and Yilmaz, 2015;Hassan et al, 2019). It has many advantages whereas able to deeply penetrate pallet loads of products, no development of insect resistance and no residue in irradiated food with low doses treatments (El-Naggar and Mikhaiel, 2011;Ayvaz and Tuncbilek, 2006;Hallman 2013 ).…”
