Vegetables are of good nutritional value with significant potential as
income-generating crop and as supplements to diet consisting mostly
carbohydrates. Despite the importance of vegetables there are different
production constraints wherever they are grown in the country. The
attack by a variety of insect pests is a major factor restraining
increased production of vegetables and is the main cause of low quality
and yield. Because of high vulnerability of vegetables to insects,
farmers lean to apply chemicals for saving these most perishable
agri-products. Farmers adopt different plant protection strategies which
mainly focus on over and heavy use of pesticides on these crops. As the
pesticide applications are repeated at three days interval therefore
there is much chance that the application of pesticides will not only
damage the environment but will also incurs severe health concerns on
the end consumers.
