Abstract:
In the recent years, as a result of the increase of anthropogenic influence on the environment, global ecological changes have taken place - climatic rise in temperature, soil erosion, deforestation, desertification etc. We face a rapid increase of pathogenic microorganisms which cause various infections such as malaria, yellow fever, dengue, rift causing great economical damage to many countries. Biological control with entomopathogens can provide a good control of pests, reduce the population of mosquitoes and decrease damage to human health. The efficacy of entomopathogenic nematodes (EPNs) of the species Steinernema feltiae and bacterial pesticides: Bitoxybacillin (BTB), Thuringin-2 and Dipel were evaluated in the control of two species of mosquitoes: Anopheles maculipennis and Culex pipiens molestus in the laboratory conduction. The mosquitoes mortality grew with increase of concentration of bacterial pesticides. On the 5th day with the high concentration of Thuringin-2 and Dipel, mortality rate of insects increased, although it did not reach 100%. The maximum mortality (100%) of mosquito larvae was observed only when exposed to BTB. It can be concluded that suspension of entomopathogenic nematodes of the species S. feltiae with dose 100 IJs /per larvae showed slight activity (36%-40%), compared with bacterial pesticides toward the larvae of the indicated mosquito species where the mortality ranged between 45 and 100%.
