Susceptibility of anopheles pharoensis to synthetic pyrethroids compared with an insect growth regulation

ABSTRACT

Three synthetic pyrethroids and an insect growth regulator [IGR] were evaluated against larvae and pupae of An.pharoensis. Of all compounds tested the decamethrin was the most effective. An.pharoensis were more susceptible at LC[90] level to the synthetic pyrethroids than to IGR Altosid SR-10. LC[90] values for decamethrin, permethrin, fenvalerate and Altosid against larvae were 0.03 - 2.40 - 7.90 and 9.4 ppb respectively. LC[90] values for these compounds against pupae were 0.4 - 4.8 - 12.8 and 13.3 ppb respectively
