Some Plasmodium species have the ability to modify the behaviour of their mosquito vectors. This is thought to be an adaptive strategy that maximizes the parasite's transmission.
The effect of Plasmodium relictum infections on the blood feeding behaviour of Culex pipiens quinquefasciatus mosquitoes was monitored.
Plasmodium infections did not alter the proportion of blood fed mosquitoes but they did affect the dynamics and the size of the blood meal. Sporozoite-infected mosquitoes completed their blood meal 1.3 times later than uninfected mosquitoes and ended up with smaller blood meals.
The potential adaptive nature of this manipulation of mosquito behaviour is discussed in the light of previous studies on other malaria models.
有些疟原虫物种有能力改变其蚊媒的行为。这被认为是一种适应性策略,可以最大限度地提高寄生虫的传播。
监测间日疟原虫感染对库蚊吸食血液行为的影响。
疟原虫感染不会改变吸食血液的蚊子比例,但会影响血液摄入量的动态和大小。感染子孢子的蚊子比未感染的蚊子晚 1.3 倍完成血液摄入,并且血液摄入量较小。
根据其他疟疾模型的先前研究,讨论了这种对蚊子行为的操纵的潜在适应性。
