Insect population is raising day by day and the crops have become more susceptible to pest attack. Although some pests could be controlled by their natural enemies but some pest are essential to be controlled by pest management. The demand for crops is increasing but the minimum yield is producing due to huge crop damage by multiple insects, pests and other micro-organisms. These pests are the source of production of wide variety of diseases to plants damaging whole crop of the year, not only spoiling quality of crops, causing diseases, but also causing huge economic loss at agricultural level. In this research paper we will describe pest’s management strategies that would be responsible for eradicating pests to improve quality of crops with minimum crop damage. Biological control is an effective method for managing pests and it proves to be fruitfull at much extent. B. thurengiensis has ability to produce crystal inclusion bodies which are known as Delta endotoxins or insecticidal crystal proteins which have resistance and toxic effects against targeted pests based upon its specifity of mode of action. Various strains of B. thurengiensis has been discover yet on the basis of presence of various antigens on its surface and production of its toxicity. It has ability to produce cry (crystal) genes which show toxicity against pests and within a short period of time the insect die due to its toxic effects.
