Book on efficacy of plantoil-powder against rice mealmoth on groundnut

Groundnut, Arachis hypogea Linnaeus is an important oil seed crop which is native to South America.It is also known for its high-oil edible seeds which are thus the fourth most important source of edible oil in the world. It is the third largest source of vegetable protein.Groundnut oil is edible and therefore, it is extensively used as a cooking medium both as refined oil and vanaspati ghee. More than 100 species of insects that infest stored groundnuts are reported in documents. Approximately 6 to 10% of groundnut kernels are destroyed by insect pests stored in bag.C. cephalonia popularly known as the "Rice meal moth" or the Flour moth belongs to the family Pyralidae and order Lepidoptera.The rice moth, C.cephalonica causes not only sanitation problem in warehouses but also hinders the commodities qualitatively and quantitatively. The creamy white larva starts feeding on the grains immediately after hatching. The larva damages the stored food by moving, feeding and leaving silken threads which later form dense and tough webbing.Pupation takes place either within the food source, in sacking or in crack-crevices in storage structures. The life cycle of rice moth takes around 4 days.
