Indian stick insects were deprived of their Corpora allata during the 4th larval instar and kept together with untreated control animals in 18° or 28° C. The amounts of Carotenoids, Biliverdine and Xanthommatine of the body -excluding eyes, gut and ovary - have been determined. 1. Neither in operated animals nor in normal controls there were marked temperaturedependent differences in Biliverdine and in absolute Carotenoid content. 2. The relative Carotenoid content with respect to body weight increased in operated animals temporarily. Afterwards it decreased beneath that of control animals. This may be an effect of the deposition of Carotenoids into the ova, as the allatectomized animals undergo premature metamorphosis. 3. The Biliverdine content decreases after operation due to blood loss. Later on it increases again, showing that Biliverdine-synthesis is not dependent on the presence of Corpora allata. 4. Higher temperature increases the Xanthommatine content in normal animals but not in animals deprived of their Corpora allata. This may also be an effect of premature metamorphosis, as ommochrome synthesis is reduced in adult animals. 5. Black covering of the ventral halves of the eyes increases the ommochrome content even in the animals without Corpora allata. This indicates, that the morphological colour adaption is not dependent on the presence of Corpora allata.
在印度竹节虫处于第4龄幼虫期时摘除其咽侧体，并将其与未处理的对照动物一起饲养在18℃或28℃环境中。已测定了（不包括眼睛、肠道和卵巢的）虫体的类胡萝卜素、胆绿素和黄蝶呤含量。1. 在手术动物和正常对照动物中，胆绿素和类胡萝卜素绝对含量均未表现出明显的温度依赖性差异。2. 手术动物中，相对于体重的类胡萝卜素相对含量暂时增加。之后，其降至对照动物之下。这可能是由于类胡萝卜素沉积到卵中所致，因为去咽侧体动物会过早变态。3. 手术后，由于失血，胆绿素含量降低。之后它又再次升高，表明胆绿素的合成不依赖于咽侧体的存在。4. 较高温度会增加正常动物中的黄蝶呤含量，但不会增加去咽侧体动物中的黄蝶呤含量。这也可能是过早变态的一个效应，因为成年动物中的眼色素合成减少。5. 即使是在没有咽侧体的动物中，眼睛腹侧一半的黑色覆盖也会增加眼色素含量。这表明，形态学颜色适应不依赖于咽侧体的存在。
