采采蝇（双翅目：舌蝇科：舌蝇）在子宫内成熟其后代，产下成熟幼虫，钻入土壤中并化蛹。在炎热干燥的季节，某些采采蝇种类的蛹聚集在茂密灌木丛的深荫处。我们已经证实 Glossina morsitans morsitans Westwood 幼虫的预蛹排泄物中存在化学信息素，并报告了 Glossina morsitanscentralis Machado 中存在类似的化学信息素。这些化学信息素对怀孕的雌性具有吸引力，并导致蛹聚集。 G. m. 的行为研究Centralis表明，较高比例的雌性幼虫产卵在受幼虫肛门分泌物调节的潮湿沙子上。 G. m. 条件下沙子提取物的触角电图分析。 Centralis 和 G. m.莫西坦斯证实触角上存在化学信息素的嗅觉受体。两个亚种都对对方的化学信息素提取物有反应，G. m. morsitans 对较低浓度的 G. m. 提取物更敏感。中枢比相反。
Tsetse flies (Diptera: Glossinidae: Glossina) mature their offspring in utero, giving birth to mature larvae that burrow into soil and pupariate. During the hot dry seasons, puparia of some species of tsetse are aggregated in areas of deep shade in dense thickets. We have confirmed the presence of a semiochemical from the prepupariation excretions of larvae of Glossina morsitans morsitans Westwood and report A similar semiochemical in Glossina morsitans centralis Machado. These semiochemicals are attractive to gravid females and result in the aggregation of puparia. Behavioral studies with G. m. centralis showed that a higher percentage of females larviposited over moist sand conditioned by the anal exudate of larvae. Electroantennogram analyses of extracts of sand conditioned by G. m. centralis and G. m. morsitans confirmed the presence of olfactory receptors on the antennae for the semiochemicals. Both subspecies responded to extracts of the semiochemicals of the other, with G. m. morsitans more responsive to lower concentrations of extract of G. m. centralis than the converse.
