Better sampling techniques are urgently required for estimating the population size and larval mortalities of the Anopheles gambiae complex. Some preliminary investigations into these problems were therefore made in Nigeria and Kenya. Knowledge of the type of distribution shown by larvae is important since it should enable more accurate sampling to be undertaken; consequently the biological distribution of larvae of the An. gambiae complex was investigated. Because there is often a need in control programmes to compare larval mortalities between populations in different types of habitat, attempts were made to construct time-specific survivorship curves and life tables so that instar mortalities could be calculated. Finally, results from estimating the size of larval populations in different habitats by a selective removal method and by a mark-release-recapture method were compared; the latter are considered more reliable.
迫切需要更好的抽样技术来估计冈比亚按蚊复合体的种群规模和幼虫死亡率。因此，在尼日利亚和肯尼亚对这些问题进行了一些初步调查。了解幼虫呈现的分布类型很重要，因为这应能使抽样更加准确；因此，对冈比亚按蚊复合体幼虫的生物学分布进行了调查。由于在控制项目中经常需要比较不同类型栖息地种群之间的幼虫死亡率，因此尝试构建特定时间的存活曲线和生命表，以便能够计算龄期死亡率。最后，比较了通过选择性清除法和标记释放再捕获法估计不同栖息地幼虫种群规模的结果；后者被认为更可靠。
