Phlebotomus papatasi is the main vector of zoonotic cutaneous Leishmaniasis caused by L. major in nearly all the East Mediterranean Region. Generally speaking, control of any arthropod-borne disease should be directed against both the parasite and the vector. The present study was undertaken to establish a base line susceptibility levels of the Egyptian P. papatasi to five insecticides. These insecticides were: B H C and D D T (chlorinated hydrocarbon), permethrin (synthetic pyrethroides), malathion (Organophosphorus) and propoxur (carbamate). The results obtained revealed that the laboratory bred P. papatasi were more susceptible to the five insecticides than the wild caught ones. The insecticidal efficiency of the five insecticides based on LC50 was in the following descending order: propoxur, permethrin, BHC, DDT and malathion for laboratory bred flies and propoxur, permethrin, BHC, malathion then DDT for wild caught flies. The least LC50 was when using propoxur for both the wild caught flies (0.0014%) and laboratory bred ones (0.00043%). The least LT50 was when using propoxur for both the wild caught flies (4.8 seconds) and the laboratory bred flies (2.2 seconds).
巴氏白蛉是东地中海地区几乎所有由硕大利什曼原虫引起的人畜共患皮肤利什曼病的主要传播媒介。一般来说，对任何节肢动物传播疾病的控制都应针对寄生虫和传播媒介。本研究旨在确定埃及巴氏白蛉对五种杀虫剂的基线易感性水平。这些杀虫剂分别是：六六六和滴滴涕（氯代烃类）、氯菊酯（合成拟除虫菊酯类）、马拉硫磷（有机磷类）和残杀威（氨基甲酸酯类）。所得结果表明，实验室饲养的巴氏白蛉比野外捕获的更易受这五种杀虫剂影响。基于半数致死浓度（LC50），这五种杀虫剂对实验室饲养白蛉的杀虫效率由高到低依次为：残杀威、氯菊酯、六六六、滴滴涕、马拉硫磷；对野外捕获白蛉的杀虫效率由高到低依次为：残杀威、氯菊酯、六六六、马拉硫磷、滴滴涕。对野外捕获白蛉和实验室饲养白蛉而言，使用残杀威时半数致死浓度（LC50）最低，分别为0.0014%和0.00043%。对野外捕获白蛉和实验室饲养白蛉而言，使用残杀威时半数致死时间（LT50）最短，分别为4.8秒和2.2秒。
