Toxicities and Cross-Resistance of Imidacloprid, Acetamiprid, Emamectin Benzoate, Spirotetramat, and Indoxacarb in Field Populations of Culex quinquefasciatus (Diptera: Culicidae).

The results of this study revealed possible cross-resistance among some of the tested insecticides but not among others; thus, the findings may be useful for the continuous management of insecticide resistance in I Cx. quinquefasciatus i . 2.

Pair-wise correlation coefficient analysis of the LC SB 50 sb values of the tested insecticides in I Cx. quinquefasciatus i field populations revealed that most of the insecticides were positively correlated in terms of their toxicities, indicating the possibility of an underlying cross-resistance mechanism. Thus, it is necessary to evaluate the susceptibility/resistance status of insect vectors to commonly used insecticides and select the most appropriate and effective insecticide for use in practice [[9]].
