在坦噶尼喀沿海地区，由恶性疟原虫引起的全地方性疟疾十分流行。大多数攻击都发生在儿童身上；成年人似乎表现出相当大的免疫力。按蚊是主要的蚊子。 A. funestus 和 A. gambiae 的雌性在卵子发育之前都需要吸血 2 次，这至少需要 48 小时。成年雌性在吸食感染性血液后大约需要 13 天才能具有感染性。数据表明，婴儿平均被咬伤一次。大约每 100 个晚上就会发生一次，由此产生的寄生虫血症会在 100 多天内感染更多的蚊子（有时多达 200 只）。建议最好的控制方法是采取措施，缩短蚊子的预期寿命，使寄生虫循环无法大量完成，而不是试图完全消灭昆虫。狄氏剂类型的杀虫剂由于其持久的残留效应而似乎提供了这样的攻击剂。
In a coastal area of Tanganyika, holo-endemic malaria due to Plasmodium falciparum is prevalent. Most attacks are evidenced in children; the adults seeming to show considerable immunity. Anopheles funestus is the predominant mosquito present. Females of A. funestus and A. gambiae both require 2 blood meals before their eggs can be developed, and this takes at least 48-hrs. Adult females require about 13 days after feeding on infective blood before they can become infective. Data indicate that an infant receives an infective bite on anavg. of about once in 100 nights, and that the resulting parasitemia nsrsists to infect more mosquitoes for over 100 days (occasionally up to 200). It is suggested that the best control is through measures designed to shorten the life expectancy of mosquitoes to a point where the parasite cycle cannot be completed in any great number rather than trying to exterminate the insect completely. Insecticides of the type of dieldrin seem to provide such an agent of attack because of its lasting residual effect.
