S.在某些条件下，在头外翻后不久和成虫的触角可见之前，即在蛹形成后约40小时，银口蝇在蛹中表现出发育停滞的状态，被认为是滞育。滞育发生在：培养物在13.5[degree]C下培养并维持，培养物在18[degree]C下在短日照-8小时光照/16小时黑暗（LD [light/dark] 8：16）的条件下培养。当幼虫在较高的温度下饲养时，滞育也会发生，而前蛹或幼蛹转移到13.5[degree]C。滞育不会从23到18[degree] C的转移中产生，LD 8：16。在这两种情况下，滞育的发展在6至12个月后自发开始。当转移到更高的温度时，在13.5 [degree]C滞育几乎立即开始，而在18[degree]C，LD 8：16滞育只有在延迟之后才开始，延迟的长度取决于所采用的温度。18 ℃，LD 8：16滞育也缩短了6[度]C冷却1至2个月。滞育在S. bullata与S. argyrostoma，但与它不同的是，它迄今为止还没有引起短的日子，并在13.5[degree]C滞育后自发终止较短的时间。在某些情况下，在触角刚刚可见的状态下发生了发育停滞。
S. argyrostoma shows under certain conditions a state of arrested development, recognized as a diapause, in the pupa shortly after the head has become evaginated and before the antennae of the adult fly become visible, i.e. about 40 hr. after formation of the puparium. Diapause occurs in: cultures raised ana maintained at 13.5[degree]C and cultures raised at 18[degree]C under conditions of short days-8 hr. light/16 hr. darkness (LD [light/dark] 8:16). Diapause also arises when larvae are raised at higher temperatures and the prepupae or young pupae transferred to 13.5[degree]C. Diapause does not ensue from transference from 23 to 18[degree] C, LD 8:16. In both cases of diapause development starts spontaneously after 6 to 12 months. Upon transference to higher temperatures development in the13.5[degree]C diapause starts almost immediately, whereas in the 18[degree]C, LD 8:16 diapause it starts only after a delay the length of which depends on the temperatures employed. The 18"C, LD 8:16 diapause is also shortened by chilling at 6[degree]C for 1 to 2 months. The diapause in S. bullata is manifested inexactly the same morphological state as in S. argyrostoma, but differs from it in that it has so far not been induced by short days, and in the 13.5[degree]C diapause is terminated spontaneously after shorter periods. In certain instances arrested development occurred in the state when the antennae are just visible.
