Although various strategies such as cultural practices, physical control, mechanical control, regulatory methods, biological control, biotechnical control have been used within the scope of integrated pest management, chemical control is the most widely used strategy due to its high and rapid efficacy. However, unconscious and widespread use of chemicals cause many problems on human beings and non-target organisms via residues; as well as, increase the resistance in target pests. In order to reduce all these problems, the demand for alternative methods and products in pest control has increased in the recent years. The use of biopesticides, in particular those based on Bacillus thuringiensis (Bt), have increased due to its low negative effects on the environment and host specificity. In order to test whether the common phenomenom on the resistance devoloped against synthetic chemicals is valid for also Bt-based biopesticides, the select pests Culex pipens L. (Diptera: Culicidae), Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) that are commonly being controlled by Bt, have been reviewed in terms of their resistance mechanisms against Bt in the current study.
