Cowpea grains, stored as dry seeds, form an enormous reserve of foodstuff in the semi-arid tropics covering Asia, Africa, Central and South America. Effect of g-irradiation on seed color, functional and pasting properties of six selected cowpea cultivars was investigated. Color (L*a*b*) of non-and g-irradiated cowpea cultivars was measured, and the deltachroma (DC), color difference (DE) and hue angle were calculated. Functional and physicochemical (pasting) of the milled cowpeas were determined using standards methods and rapid visco-analyzer, respectively. Generally, L*, a* and b* values of cowpea seeds were significantly (P Յ 0.05) affected by irradiation dose. Calculated chroma, color intensity and hue angle varied with cultivar and g-irradiation dose. Oil absorption capacities of the nonirradiated and irradiated cowpea flours varied from 1.08 to 1.30 and 0.94-1.20 g oil/ g sample, while the water absorption capacities ranged from 1.59 to 2.00 and 1.58-2.01 g water/g sample, respectively. Nonirradiated cowpea flours showed higher pasting properties (peak, trough, breakdown, final and setback viscosities) than the irradiated cowpea. Aside from breakdown viscosity, the pasting properties decreased significantly (P < 0.05) with increased g-irradiation dose. The IT96D-610 and IT97K-568-18 cultivars showed significantly higher peak, trough, final and setback viscosities compared with other cowpeas. PRACTICAL APPLICATIONSExposing foods to ionizing radiations such as gamma rays emitted from the radioisotopes 60 Co and 137 Cs, or high energy electrons and X-rays produced by machine sources, helps to destroy microorganisms or insects present in the food. Depending on the absorbed radiation dose, various effects can be achieved resulting in reduced storage losses, extended shelf life and/or improved microbiological and parasitological safety of foods. Microorganisms and pests can no longer proliferate and continue their activities, and insect gametes do not survive or become incapable of proliferation. Large quantities of stored legumes are lost annually as a result of mould contamination and insect attack which continues after harvesting even to storage. Irradiation of cowpea is a viable alternative to the use of chemicals, which have adverse effects on both food and environment, associated with residues and ozone depletion, and are perceived to be carcinogenic. bs_bs_banner Journal of Food Process Engineering

“…Boshra (1994) reported that the dose required to disinfest and/or sterilize both males and females was 120 Gy. Ionizing treatment dose less than 100 Gy had utilized to sterilize the adults and elimination of the eggs, larvae, and pupae without bringing about troublesome healthful outcomes (Diop, Marchioni, Ba, & Hasselmann, 1997). IAEA (2002) had prescribed that the 100 Gy is the minimum dose required to sterilize the adult of C. chinensis.…”

The southern cowpea weevil, Callosobruchus maculatus (F) is a severe agriculture pest worldwide. In the current work, newly emerged adult males of C. maculatus have been irradiated with a low dose of 20Gy gamma radiation. The inherited deleterious effects on the fecundity, hatchability, adult emergence, and the sterility percent were recorded for the progenies F1 and F2 of the irradiated parental males. The fecundity, hatched larvae, the number of males and females were reduced in both F1 and F2. The sterility percent was high in F1 (70.8%) and increased in the F2 (88.3%) generation. Histopathological effects were also documented in the testes of F1 and F2 progenies. The spermatids and sperms have exhibited a variety of abnormalities. In the early spermatids, the nebenkern outer cell membrane was ruptured. The spermatid nucleus loses its homogeneous texture and has multiple foci of dense chromatin, as well as, profiles range has little dense material. In some groups, the nucleus had a peculiar ring of chromatin. The sperms had shown a variety of aberrations. The sperms irregularity distributed in lysed cysts by unusual manner. Also, some sperms had remarkably enlarged axoneme and small rounded nucleus. Many of the sperm cells were observed with two axonemes, abnormal mitochondria derivatives, and more than two accessory bodies. These results indicate that the low dose of 20 Gy induces semi-sterility in C. maculatus through generations. The same technique would help to improve using of sterile insect technique for other agriculture pests.

“…Irradiation and essential oil utilization are two methods that could be used in IPM (Sharma and Seth, 2005). Both genera Bruchus and Callosobruchus, the main stored-product pests, are observed to be sensitive to irradiation (Diop et al, 1997). Roy and Prasad (1993) noticed that a dose of 1 kGy of gamma radiation killed all the adults of Callosobruchus chinensis L. within a week.…”

In order to examine possible integration between irradiation and botanical pesticides, combined effects of essential oil from Rosmarinus officinalis L. and gamma radiation were determined on mortality of Callosobruchus maculatus F. (Coleoptera: Bruchidae). Experiments were conducted by pretreatment with essential oil fumigation followed by irradiation and inversely, pretreatment with irradiation followed by essential oil fumigation. The mortality rate was assessed 72 h after last treatment. Integration of gamma radiation and R. officinalis oil enhanced the mortality of C. maculatus compared with control treatments of either irradiation or fumigation alone. Synergistic effects of mortality on 1-2 days old adults of C. maculatus were observed when exposed to combination of gamma radiation and essential oil. It was found that pretreatment with fumigation followed by irradiation was perfectly effective. The study showed that either of the pretreatments could enhance the susceptibility of the pest to the other treatment. Our findings led to a conclusion that the combination of gamma radiation and R. officinalis oil fumigation has a potential for application in integrated management of C. maculatus.
