Abstract

During storage of legumes, severe losses can occur due to the attack of pulse beetle (Collosobruchus chinensis). It has been estimated that the loss in weight of a seed of cow pea due to single larva of Collosobruchus maculatus can be between 3.3 to 5.6 per cent. Use of vegetable oils in protecting pulses during storage is a traditional practice. Several workers have studied the effectiveness of various oils as grain protectants and found to be effective. In the present study, an effort was made to test the efficacy of neem, mohua, palm oil and karanja oils as a pre-storage treatment to green gram and its effect on certain nutrients.

Abstract

Milled cereals are more susceptible to the hazards of storage such as moisture, temperature, fungi, bacteria, insects and other pests. Among the milled cereals, maida and suji are invariably infested by rust red flour beetle, Tribolium castaneum, which may start from the field, field drying, stacking, threshing, milling and transportation. The flour beetles cause discolouration of the flour, secrete off-smelling liquids into flour, contaminate by their cast skins, fecal pellets and uric acid resulting in urinary infections in mammals. The need for disinfection is particularly acute in warm countries, where insects breed rapidly.

Abstract

Cauliflower (Brassica oleracea var. Botrytis Linn.) is severely attacked by several insect pests particularly diamond back moth, Plutella maculipennis Curtz., and aphids Lipaphis erysimi Katt. Several insecticides have been in usage against the insect pests of cauliflower and application of spray formulated of quinalphos proved to be very effective in controlling them. However, the dissipation of quinalphos on cauliflower curds and leaves is necessary for recommendation of its safe use. Hence, an attempt was made to determine the persistance of and the removal of quinalphos residues by processing procedures in cauliflower curds. Dissipation of quinalphos at room and refrigeration storage temperatures and its interaction with nutrients is also reported.
