Microbes as interesting source of novel insecticides: A review

Microbes are ubiquitous, survive in all sorts of environments and have a profound influence on the\udearth. In the present day plant protection scenario, development of resistance to chemical pesticides is\udthe major hurdle in insect pest management. In recent years, several microbes with potential\udinsecticidal properties have come to light. Viruses, bacteria, fungi and protozoa that are known to\udproduce an array of metabolites or toxins, form the basis for microbial insecticides. Since these\udversatile organisms are amenable for genetic engineering, strains with good insecticidal properties can\udbe identified, evaluated and utilized for pest control. This paper reviews the insecticidal properties of\udmicrobes and their potential utility in pest managemen
