Özet

In India, the pulse beetle, Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae), is the most serious pest of stored green gram or mung bean [Vigna radiata (L.) R. Wilczek], causing a considerable loss in quality, quantity and seed viability. The control of the pest relies heavily on the use of synthetic chemicals with some drawbacks, especially insect resistance, health and environmental effects. Hypoxic atmospheres (decreasing oxygen; O2 and increasing carbon dioxide; CO2) could be one of the most eco-friendly promising alternative management methods of C. maculatus in stored green grams. Hypoxia condition of some storage containers and their effects on pulse beetle population growth were evaluated under laboratory conditions for up to four months. Glass bottles had the highest O2 depletion (declined from 20.7 to 2.9%) and CO2 accumulation (increased from 0.03 to 18.6%) up to 120 days of storage. Apart from glass bottles, triple-layer bagging, LDPE bags, PET bottles and black polyethylene bags with high thickness showed O2 depletion and CO2 increase. The glass bottles containing green gram seeds also had the lowest population of C. maculatus ranging from 15.6 to 36 adults per bottle after different periods (from 30 to 120 days) of storage, followed by triple-layer bagging with the numbers of adults ranging from 19.3 to 51.3 per bag. Overall, the results suggest that glass bottles, triple-layer bagging of polyethylene bag, LDPE and black polyethylene bags can be advised for green gram storage because of their effectiveness in mortality and reduced progeny development.
