Biology of malaria vectors were studied in Kheda district of central Gujarat in order to understand the vector behaviour in the wake of ecological changes. Anopheles culicifacies and An. stephensi were mainly endophilic whereas An. fluviatilis exhibited marked exophily. All the three vectors were predominantly zoophilic. Peak biting activity period of An. culicifacies varied with season though biting continued in varying magnitudes throughout the night. An. stephensi and An. fluviatilis were arhythmic in their biting activity. Survival of all the three vectors was maximum during cold season owing to longer gonotrophic cycle which also yielded higher estimates for expected infective life. Instability of malaria in this area was probably due to low estimates of expected infective life for the three vectors. A wide range of breeding habitat preferences by An. culicifacies was observed whereas An. fluviatilis and An. stephensi showed restricted distribution.
为了解生态变化后疟蚊媒介的行为，在古吉拉特邦中部的凯达区对疟蚊媒介生物学进行了研究。库氏按蚊和斯氏按蚊主要为嗜内性，而溪流按蚊表现出明显的嗜外性。这三种媒介均主要为嗜动物性。库氏按蚊的叮咬高峰期随季节变化，不过夜间不同时段均有不同程度的叮咬。斯氏按蚊和溪流按蚊的叮咬活动无规律。由于生殖营养周期较长，这三种媒介在寒冷季节的存活率最高，这也使得预期感染寿命的估计值更高。该地区疟疾的不稳定可能是由于这三种媒介的预期感染寿命估计值较低。观察到库氏按蚊对多种繁殖栖息地有偏好，而溪流按蚊和斯氏按蚊的分布则较为局限。
