Adult and larval insecticidal tests conducted in Panaji, Goa, revealed that adults of An. stephensi were resistant to DDT (4.0%), dieldrin (0.4%) and malathion (5.0%). The larvae of An. stephensi were also resistant to DDT (2.5 mg/l) and malathion (3.125 mg/l). Cx. quinquefasciatus adults were resistant to DDT, dieldrin, malathion and fenitrothion (1.0%), and larvae were highly resistant to DDT but showed low resistance to malathion and fenitrothion (0.125 mg/I). Adults of Ae. aegypti were resistant to DDT and dieldrin and the larvae showed resistance to DDT but good susceptibility to fenitrothion and complete susceptibility to malathion. The triple resistance of An. stephensi to DDT, dieldrin and malathion is intriguing as malathion has never been used in the health sector in Goa. A very limited use of malathion was done in the agricultural sector in Chandor area, which is 50 km away from the study area.
在果阿邦帕纳吉进行的成虫和幼虫杀虫剂测试显示，斯氏按蚊成虫对滴滴涕（4.0%）、狄氏剂（0.4%）和马拉硫磷（5.0%）具有抗性。斯氏按蚊幼虫对滴滴涕（2.5毫克/升）和马拉硫磷（3.125毫克/升）也具有抗性。致倦库蚊成虫对滴滴涕、狄氏剂、马拉硫磷和杀螟硫磷（1.0%）具有抗性，幼虫对滴滴涕高度抗性，但对马拉硫磷和杀螟硫磷（0.125毫克/升）显示低抗性。埃及伊蚊成虫对滴滴涕和狄氏剂具有抗性，幼虫对滴滴涕具有抗性，但对杀螟硫磷敏感且对马拉硫磷完全敏感。斯氏按蚊对滴滴涕、狄氏剂和马拉硫磷的三重抗性令人关注，因为马拉硫磷在果阿邦卫生部门从未使用过。在距离研究区域50公里的钱多尔地区农业部门曾非常有限地使用过马拉硫磷。
