“…These findings agree with previous reports of decrease in moisture, and carbohydrate contents of V. unguiculata infestation of C. maculatus [7]. Similar results of decrease in moisture, ash, fibre, fat and carbohydrate with an increase in protein content of Phaseolus lunatus seeds infested by Acanthoscelides obtectus [8]. Protein content of seeds increased with severity of infestation.…”

“…Dry sandy soil is most suitable for the production of moth bean, and the bean can tolerate a variety of soil types [18]. Sandy and loamy soils are more effective for the germination of A. obtectus infested and non infested seeds of Lima bean (P. lunatus) than clay soil [8]. The lowest mean and percentage germination of infested and non infested seeds of V. aconitifolia (moth bean) on clay soil may be attributed to poor aeration since clay soils are composed of lot of tiny mineral particles which reduces the air spaces in the soil.…”

“…Callosobruchus maculatus infestation significantly damaged seeds of Vigna unguiculata resulting in reduced seed germination and altered nutrient quality of stored beans [7]. Infestation of Phaseolus lunatus by the cowpea weevil, Acanthoscelides obtectus reduced seed germination with changes in the biochemical composition of seeds [8]. This damage caused by storage pests is threatening as global population growth is estimated to 9 billion persons inhabiting the Earth by 2050, a 60% increase in food production must be attained.…”

“…33 Similar alterations have been seen in C. maculatus infested Vigna unguiculata, Acanthoscelide obtectus and Phaseolus lunatus seeds. 34,35 The presence of insects in the seeds increases the relative humidity due to insect transpiration and subsequently increase in the water content of the seeds. 36 The observed decrease in carbohydrate content of the seeds after C. maculatus infestation can be explained by the decrease in starch and crude cellulose and the increase in reducing sugar and glucose resulting from the enzymatic and metabolic activity of the insect.…”

One of the most severe pests of legume seed is the chickpea weevil, Callosobruchus maculatus (C.m), which attack chickpea seeds (Cicer arietinum). The fight against this insect pest has mostly been limited to chemical control with its attendant environmental and health effects. The pest has also developed resistance to the chemical pesticides. The present study therefore aim to evaluate the insecticidal effect of Lavandula dentata (L.d) Essential oil (EO) on adult insects of C.m, and also to assess the impact of the insect infestation and EO treatment on chickpea seed quality. L.d EO was applied by fumigation at doses of 1, 5, 10, 20 and 40 µL/L of air to 100 g of chickpea seeds. The mortality of the insects was determined by probit analysis after 24 h exposure. The impact of the insect infestation and EO treatment on the chemical composition of chickpea seeds were also assessed. The constituents of the essential oil were determined by GC-MS analysis. L.d EO had significant insecticidal effect on the adult insects of C.m, even at low concentrations. Results from the probit analysis showed that L.d EO had LC50 of 19.43 µL/L air against C.m. The infested seeds were severely damaged with significant effect on their chemical composition and reduction in their nutritional quality. Fumigation with L.d EO did not significantly affect the chemical composition of the chickpea seeds. Linalool (35.62%) was identified as the major constituent of L.d EO. L.d EO could therefore serve as a source of biopesticides against chickpea weevil.

Stored dry common bean seeds are subject to infestation by Acanthoscelides obtectus, which reduces the quality of the infested seeds and depletes their nutritional value, making them unfit for human consumption. The susceptibility of three Egyptian varieties to infestation by A. obtectus was investigated. The Nebraska variety was the most susceptible, with 34.5 and 62% infestation at artificial infestation levels that included 5 and 10 pairs of insects for every fifty seeds, respectively, followed by the Karnak and Giza 6 varieties. The maximum weight losses as a result of insect infestation were observed for Nebraska seeds, and as expected, the maximum numbers of emerged adults after 50 days of storage were also observed for this variety. Maximum means of infested seeds were recorded in the Nebraska and Karnak varieties at the 10- pair infestation level. According to the infestation index, the Giza 6 and Karnak varieties were moderately resistant, while the Nebraska variety was susceptible at the 10-pair infestation level. Moreover, changes in the chemical composition of infested dry common bean seeds were inconsistent, with increases in some nutritional properties (protein and fibre contents) and decreases in others (moisture, carbohydrate and fat contents).
