Insects represent 85% of the animals. They have adapted to many environments and play a major role in ecosystems. Many insect species exhibit phenotypic plasticity. We here report on the mechanisms involved in phenotypic plasticity of different insects (aphids, migratory locust, map butterfly, honeybee) and also on the nutritional size plasticity in Drosophila and the plasticity of the wing eye-spots of the butterfly Bicyclus anynana. We also describe in more detail our work concerning the thermal plasticity of pigmentation in Drosophila. We have shown that the expression of the tan, yellow and Ddc genes, encoding enzymes of the melanin synthesis pathway, is modulated by temperature and that it is a consequence, at least in part, of the temperature-sensitive expression of the bab locus genes that repress them.
昆虫占动物种类的85%。它们已适应多种环境，并在生态系统中发挥着重要作用。许多昆虫物种表现出表型可塑性。我们在此报告不同昆虫（蚜虫、飞蝗、地图蝶、蜜蜂）表型可塑性所涉及的机制，以及果蝇的营养大小可塑性和蝴蝶Bicyclus anynana翅眼斑的可塑性。我们还更详细地描述了我们关于果蝇色素沉着热可塑性的研究工作。我们已经表明，编码黑色素合成途径中酶的tan、yellow和Ddc基因的表达受温度调节，并且这至少部分是由于抑制它们的bab基因座基因的温度敏感表达所致。
