Food is any substance consumed to provide nutritional support for the body. Historically, people secured food through two methods: Hunting and gathering, and agriculture. Today, the majority of the food required by the ever increasing population of the world is supplied by the food industry based on agriculture produce. Third agricultural revolution concentrated on industrialization of agriculture with mechanization, chemical farming, food manufacturing, addition of economic value through processing, canning, refining, packaging, green revolution, plant breeding, biotechnology, genetic manipulation, etc. Crop products are eventually stored for varied periods of time depending on market demand, size of production and the farmer’s needs. Herbivorous insects are said to be responsible for destroying one fifth of the world’s total crop production annually. By their very nature, most insecticides create some risk of harm to humans, animals or the environment. Unfortunately, some of the highly hazardous insecticides are continually and indiscriminately used globally. The small farmers prefer those because they are cost-effective, are easily available and display a wide spectrum of bioactivity. It is for sure that insecticides, once enter the environment will have negative impacts on air, water, soil, human beings and animals. Some suggested management strategies include: Integrated pest management (IPM); Use of resistant varieties; Employing biological control measures; Use of bio-pesticides, Sterilization technique, Sex attractants and Pheromones and above all educating farmers. Food safety and food security are monitored by agencies like the: International Association for Food Production, World Resources Institute, World Food Program, Food and Agriculture Organization and International Food Information Council. They address issues such as sustainability, biological diversity, climate change, nutritional economics, population growth, water supply, and access to food.
