Studies conducted in Warangal, Khammam and Mahabubnagar districts in Andhra Pradesh and Surat district in Gujarat have revealed that Anopheles culicifacies sensu lato (s.l.) populations were resistant to malathion. In the absence of indoor spraying of malathion in public health programs in the 3 districts of Andhra Pradesh, resistance is attributed to the extensive use of pesticides in agriculture. Species B and C were sympatric in all areas surveyed, and both the species were resistant to malathion. In most of the surveys carried out in Mahabubnagar, Khammam and Warangal, levels of resistance were higher in species C than in B. In Mahabubnagar district an increase in resistance from 5.5 to 64% was observed from 1985 to 1987 in An. culicifacies s.l. The proportion of species C was low in the initial 2 surveys, and in the later surveys the proportion was almost equal to that of species B; the resistance level was also significantly higher than in species B. In Surat district, where resistance ranged from 74 to 93%, the level of resistance in the 2 species was almost the same.
在安得拉邦的瓦朗加尔、卡马姆和马哈布卜纳加尔地区以及古吉拉特邦的苏拉特地区开展的研究显示，嗜人按蚊复合组（Anopheles culicifacies sensu lato，s.l.）种群对马拉硫磷具有抗性。由于安得拉邦这3个地区的公共卫生项目中未进行室内马拉硫磷喷洒，这种抗性被认为是由于农业中广泛使用杀虫剂所致。在所有调查地区，B种和C种是同域分布的，且这两个种类均对马拉硫磷具有抗性。在马哈布卜纳加尔、卡马姆和瓦朗加尔开展的大多数调查中，C种的抗性水平高于B种。在马哈布卜纳加尔地区，1985年至1987年间，嗜人按蚊复合组的抗性从5.5%增至64%。在最初的2次调查中，C种的比例较低，而在随后的调查中，该比例几乎与B种相等；其抗性水平也显著高于B种。在苏拉特地区，抗性范围为74%至93%，这两个种类的抗性水平几乎相同。
