Larvicidal oil or larvicide (such as temephos, Bacillus thuringiensis subspecies israelensis etc. ) can be applied to stagnant water directly with dosage according to the label instructions.
须直接向积水用蚊油或杀幼虫剂(例如相硫磷、桿菌属亚种苏云金桿菌等),按照标签上所列明的剂量。
Although larvicide has been distributed in 94 districts since 2002, logistic regression analysis showed no association between the intervention and dengue incidence.
