Diflubenzuron, an insect growth regulator that blocks chitin deposition in insect cuticles, was tested for its effects on morphogenesis of Streptomyces spp. Use of diflubenzuron resulted in reduced dominance of spore hairs, reduced the width of the outer wall, and prevented formation of the inner spore wall in S. bambergiensis. In S. coelicolor, diflubenzuron altered the structure of the fibrillar pattern of spore envelopes. Exposure to diflubenzuron resulted in small increases in exported protein and in a ca. 20% increase in chitinase in both Streptomyces spp.

除虫脲，一种昆虫生长调节剂，可阻止昆虫表皮中几丁质的沉积，用于测试其对链霉菌属形态发生的影响。使用除虫脲会导致孢子毛的优势减少，外壁变窄，并阻止邦贝青霉菌的内孢子壁的形成。在变铅青链霉菌中，除虫脲改变了孢子包被的纤维状图案的结构。暴露于除虫脲会导致两种链霉菌属的分泌蛋白增加约 20%，几丁质酶增加约 20%。
