Entomological studies on relative prevalence and distribution of adults and immatures of Aedes aegypti were conducted in Rajahmundry town of Andhra Pradesh from December 1998 to November 1999. Adults and immature stages of Aedes aegypti were found in all the 22 localities viz; posh area (8), mixed area (8) and slum area (6) of the town. Larval indices were found to be higher in slum areas as compared to mixed or posh areas of the town. However, the larval habitats were observed to be similar in all localities. The larval indices were highest during monsoon and post-monsoon months. The breeding preference ratio (BPR) was highest for cement tubs followed by discarded tyres and barrels. The high larval indices of Aedes aegypti in these areas warrant intensification of vector surveillance activities along with source reduction and health education.
1998年12月至1999年11月，在安得拉邦的拉贾蒙德里镇开展了关于埃及伊蚊成虫和未成熟虫态相对流行率及分布情况的昆虫学研究。在该镇所有22个地区，即高档区域（8个）、混合区域（8个）和贫民窟区域（6个）均发现了埃及伊蚊的成虫和未成熟虫态。与该镇的混合区域或高档区域相比，贫民窟区域的幼虫指数更高。然而，在所有地区观察到幼虫栖息地相似。幼虫指数在季风期和季风后期月份最高。水泥桶的繁殖偏好率（BPR）最高，其次是废弃轮胎和桶。这些地区埃及伊蚊的高幼虫指数表明，需要加强病媒监测活动，同时减少源头并开展健康教育。
