To assess whether the trachoma vector Musca sorbens was breeding in household latrines in a trachoma-endemic part of The Gambia.
Longitudinal study of flies emerging from 16 sentinel household latrines selected at random from a list of all latrines present in four Gambian villages. Latrines were surveyed and fly traps were set over the drop hole for 24 h once per month for a year.
All the sentinel latrines were of the 'Gambian improved household latrine' design, which has a cement slab but is not ventilated or fly-proofed. The latrines were all in regular use by a family, mean number of users per latrine 14.8 (SD 8.0, range 2-29). Of 55 351 flies caught in 192 catches 54 130 (97.8%) were Chrysomya albiceps, 690 (1.2%) Musca domestica, 466 (0.8%) Chrysomya regalis and 65 (0.1%) M. sorbens. Of the M. sorbens caught 61 (93.8%) were female.
Gambian improved household pit latrines cannot be considered a source of the trachoma vector M. sorbens, and the promotion of pit latrines as a method to reduce M. sorbens is warranted. A large number of C. albiceps were caught emerging from the latrines, but this species is not considered to be of medical importance.
评估在冈比亚沙眼流行地区，家蝇是否在家用厕所繁殖。
对从冈比亚四个村庄所有厕所清单中随机选取的16个定点家用厕所飞出的苍蝇进行纵向研究。对厕所进行调查，并在排水口设置捕蝇器，每月一次，每次24小时，持续一年。
所有定点厕所均为“改良冈比亚家用厕所”设计，有水泥板，但没有通风设施或防蝇设施。这些厕所均有家庭定期使用，每个厕所的平均使用人数为14.8人（标准差8.0，范围2 - 29人）。在192次捕获的55351只苍蝇中，54130只（97.8%）为白纹伊蚊，690只（1.2%）为家蝇，466只（0.8%）为帝王伊蚊，65只（0.1%）为家蝇。在家蝇捕获的样本中，61只（93.8%）为雌性。
改良冈比亚家用坑式厕所不能被视为沙眼传播媒介家蝇的来源，因此有必要推广坑式厕所作为减少家蝇的一种方法。从厕所中捕获了大量白纹伊蚊，但该物种不被认为具有医学重要性。
