Microbial Control using Entomopathogenic Fungi against Noxious Arthropods
Various arthropods have directly and indirectly threatened human life by transmitting human pathogens such as malaria and Zika virus as well as by damaging crops such as direct feeding and transmission of plant pathogens. According to WHO, vector-borne diseases account for over 17% of all infectious diseases and there are over 1 million deaths from the diseases such as malaria, dengue, etc., globally. About 13% of total crop production is destroyed by agricultural pests during crop production and storage. To control medical or agricultural pests chemical pesticides have been used, but recently because of concerns about environmental pollution and human health the demands for eco-friendly control method are increasing. Insect pathogens are good alternative candidates instead of chemicals. Over 50 entomopathogens including viruses, bacteria, fungi and nematodes are now commercially used as microbial pesticides. Entomopathogenic fungi have also been evaluated as control agents for a diverse insect pests such as aphid, moth, thrip, whitefly, mosquitoes, tick, etc. We will discuss a development of microbial pesticides using, especially, entomopathogenic fungi to control noxious arthropods to agricultural crops and human.
