Nano Bio Pesticide to Constraint Plant Destructive Pests

Insects-pest is animal populations, which occurred in every possible environment with a varied number of species. The several insects are vectors of different diseases, and cause damages to crop plants. These have been affecting economy and the yield of crop plant and at national and international market. The crop yield losses caused by insects in agriculture, several chemicals have been applied to control them [1]. Insectpests are one of the leading causes that affect agriculture productivity resulting in billion dollars loss per annum [2]. The two main forms i.e. larva and adult have been most lethal for most of the crop plants. For example, the deadly pest Helicoverpa armigera cause damage in the field and horticulture crops around the globe [3]. It has been major prevalence affecting in Asia, Europe, Africa, Oceania and South America [3]. The major crop plants that are affected by Helicoverpa armigera are Chickpea, Corn, Cotton [4], Peanut, Pigeon pea, Sorghum and Tomato. H. armigera has been effecting on over 180 cultivated hosts and 45 families of wild plant species [3]. The cotton yield is low due to 150 different pest attack at various life stages [5]. This has made an emergence for a researcher to compile the traditional and advance techniques to overcome various pest threats around the world.
