Abstract
The objectives of this research were to develop a phytosanitary irradiation treatment against 3 species of agromyzid leafminers (Diptera: Agromyzidae), and to study the effects of gamma radiation on the physical, chemical, and sensorial properties of shelled peas, Pisum sativum L. (Fabales: Fabaceae). Late pupae (pharate adults) of the 3 species were treated with Co-60 gamma radiation at 0, 80, 100, 120, 150, and 180 Gy. The measurement of efficacy used was the prevention of mine formation in leaves by Fa generation offspring of the leaf miners. Liriomyza sativa Blanchard, L. trifolii (Burgess) and L. huidobrensis (Blanchard) were found to have similar responses to the irradiation doses that prevented formation of leaf mines by Fa offspring; thus no leaf mines were formed by these 3 species in the 150 Gy and 180 Gy treatments. Confirmatory testing successfully undertaken on all
3 species using a grand total of > 30,000 pharate adults corroborated that irradiation with 150 Gy completely prevented the formation of leaf mines. The radiotolerance of shelled peas was studied to ensure that the irradiation treatment does not significantly affect the composition, palatability and flavor of the produce. Pea samples were irradiated at 0.25, 0.5 and 1 kGy and tested for vitamin C, total carotenoids, protein secondary structure, color, and sensory properties. These properties of the peas were significantly but not greatly affected by irradiation with any of the doses tested.
