abstract
Currently, the control methods against ticks are focusing on the use of insecticides that lead to high cost and adverse effect to the environment. Thus user-friendly and eco-friendly approach of biological control by using entomopathogens viz. fungi, bacteria, viruses, and nematodes, provides an alternative way. Within the bacterial group, the microorganisms most widely used worldwide in the control of several insect pests with the highest success, are the bacterium, Bacillus thuringiensis Berliner (Bacillales: Bacillaceae). The use of B.thuringiensis is increasing rapidly because it is highly specific, significantly lowering the damage to other organisms compared to use of chemical insecticides, and because it is self-perpetuating and is therefore accepted as an environmentally friendly alternative. However very scanty studies are available on bacterial pathogens against ticks. Thus an attempt is made through this review article to highlight the work undertaken on possible ways and role of bacteria in the control of ticks. The sole purpose of the present review is to compile the pertaining literature and to create the interest of researchers in this area.
