摘要
从释药动态及灭蚊幼效果观察中，比较了包装型及几种吸附型缓释剂。结果表明，包装型缓释剂虽然释药率稳定（ＣＶ为１０．５５％），但初始需增加一个有效浓度方能起杀虫作用；而硬脂酸缓释剂无需另加剂量，且释药率也较为稳定（ＣＶ为６６．０３％）；杉木块和珍珠岩缓释剂类似常规喷洒剂，但也有一定的持效。
The drug-release features of several slow-release reagents and their efficacy of killing mosquito larvae were studied. The results indicated that the drug-release rate of wrapped type slow-release reagents was the most stable(CV 10.55%), but in initial stage the insecticide concentration in the water was not high enough to kill mosquito larvae, so it was required to add dosage. The stearic acid slow-release reagent was not required to add dosage in initial stage because it was released rapidly and rather stable (CV 66.03%) and the effective duration of killing mosquito larvae was longer. The drug-release features of Chinese fir lump and pearlite slow-release reagents were similar to that of common spray method, which was released fast and resolved rapidly.
