The effect of nitrophoska on the survival rate of Aedes sp. larvae (Ae. flavescens, Ae. cataphylla, Ae. vexans) was assessed for the first time under laboratory and in situ conditions. Threshold concentration of the water solution of nitrophoska (0.4-0.5% and 1%) producing a larvicidal effect on the larvae at the I-II and III-IV stages, subsequently, was established. Changes in water chemical regime due to the effect of 0.1-0.5%, 1-3-5% nitrophoska content, were observed in water bodies with developing Aedes larvae: pH shifted towards acid by 0.2-1.4; ammonium content increased significantly: from 3.1 to 800-1600 mg/l at 0.1 to 5%% nitrophoska contents, which may be the cause of a low number of Aedes in water-bodies of rural areas or their total absence.
首次在实验室和原位条件下评估了硝磷钾肥对伊蚊幼虫（淡黄伊蚊、叶状伊蚊、骚扰伊蚊）存活率的影响。随后确定了硝磷钾肥水溶液对I-II期和III-IV期幼虫产生杀幼虫作用的阈值浓度（0.4-0.5%和1%）。在有伊蚊幼虫生长的水体中，观察到由于0.1-0.5%、1-3-5%硝磷钾肥含量的影响，水体化学状况发生了变化：pH值向酸性偏移0.2-1.4；铵含量显著增加：在硝磷钾肥含量为0.1%至5%时，铵含量从3.1毫克/升增加到800-1600毫克/升，这可能是农村地区水体中伊蚊数量少或完全没有伊蚊的原因。
