通过 3 个完整的水稻种植周期，使用光阱对冈比亚疟原虫（东非疟疾的主要传播媒介）新出现的成年种群进行了采样。第一茬作物中，幼稻从苗圃移栽到主田后，大量成虫被捕获。当稻高达到100厘米时，产量明显下降。在第二季和第三季作物中，移栽再次刺激了冈比亚蚊的繁殖，用于控制水稻害虫二化螟（Maliarpha seperella）的杀虫喷雾导致作物周期后期大量蚊子成虫出现。影响冈比亚食蚁兽在稻田繁殖的三个因素是：水深、稻高和捕食。
Light traps were used to sample the emerging adult populations of A. gambiae (the principle vector of malaria in East Africa) through 3 complete cycles of rice cultivation. In the 1st crop adults were taken in large numbers following transplanting of young rice from nursery areas to main fields. When the rice height reached 100 cm, catches fell markedly. In the 2nd and 3rd crops, transplanting again stimulated the breeding of A. gambiae, and insecticidal sprays used to control the rice pest stem borer (Maliarpha separatella) resulted in considerable mosquito adult emergence later in the crop cycle. Three factors influenced the breeding of A. gambiae in rice fields: water depth, rice height and predation.
