A 59-week study was conducted to evaluate the impact of adult Mesocyclops longisetus populations on larval mosquito species inhabiting tires. Greater than 90% reduction of number of 1st and 2nd instars was recorded by 4 wk with 90% reduction of number of 3rd and 4th instars after 7 wk. Reduced control was noted with the onset of cooler winter water temperature. Overall. a 52% reduction in the number of 1st and 2nd instars was achieved, and a 57% reduction was noted in number of 3rd- and 4th-instar mosquito larvae. Cooler temperatures resulted in a decline of adult Mesocyclops, which resulted in reduced larval control. Significantly greater numbers of Mesocyclops adults were collected in tires with either new litter or heavy amounts of litter regardless of litter type. Lastly, litter type, either oak leaves or pine needles, did not influence mosquito reduction or abundance of Mesocyclops populations.
进行了一项为期59周的研究，以评估成年长刺中剑水蚤种群对栖息在轮胎中的蚊幼虫种类的影响。4周时，一龄和二龄幼虫数量减少了90%以上，7周后，三龄和四龄幼虫数量减少了90%。随着冬季水温变冷，控制效果有所下降。总体而言，一龄和二龄幼虫数量减少了52%，三龄和四龄蚊幼虫数量减少了57%。温度降低导致成年长刺中剑水蚤数量下降，从而导致幼虫控制效果降低。无论垃圾类型如何，在有新垃圾或大量垃圾的轮胎中收集到的成年长刺中剑水蚤数量显著更多。最后，垃圾类型，无论是橡树叶还是松针，都不会影响蚊虫数量的减少或长刺中剑水蚤种群的数量。
