Observations on the breeding of anophelines in rice fields of Shahjahanpur district, Uttar Pradesh.
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.
