Studies on ecological succession and association of anophelines in selected paddy fields of Dadraul PHC were carried out in 1988 during the paddy cultivation period from June to October. Breeding of five anophelines was observed in paddy fields. Out of the adults that emerged from larval collections the percentage of An. subpictus was the highest followed by An. nigerrimus, An. culicifacies, An. annularis and An. barbirostris. Further, An. culicifacies and An. subpictus breeding occurred in the early stage of rice cultivation and stopped before the breeding of An. nigerrimus started i.e., nearly 30 days after rice transplantation. An. nigerrimus breeding continued till harvesting. An inverse correlation between larval density of both An. culicifacies and An. subpictus and the height of the rice plants was observed.
1988年6月至10月水稻种植期间，在达德鲁初级卫生保健中心选定的稻田中开展了按蚊生态演替及群落关系的研究。在稻田中观察到5种按蚊的繁殖情况。从幼虫采集样本羽化出的成虫中，伪威氏按蚊的比例最高，其次是黑须按蚊、库态按蚊、环纹按蚊和须喙按蚊。此外，库态按蚊和伪威氏按蚊在水稻种植早期繁殖，在黑须按蚊开始繁殖前停止，即在水稻移栽后近30天。黑须按蚊的繁殖一直持续到收获期。观察到库态按蚊和伪威氏按蚊的幼虫密度与水稻植株高度呈负相关。
