依昆虫激素的进展情况,基本可将其分为两大类:一类是内激素,主要是由昆虫内分泌器官分泌的、能在体液内流动的活性物质,它能调节和控制昆虫的生长、发育、变态、滞育、交配、生殖以及一般生理代谢作用。另一类是外激素,它是由昆虫体某一器官或组织所分泌的、能在体外流动的活性物质,它能借空气或其他媒介散布到体外影响同种(有时也影响异种)其它个体的特殊行为。 近几年来生态学有了重大发展,人们在化学生态领域中对生物间相互关系的形成进行了广泛的研究,发现某些化学物质起着重要的作用。昆虫与昆虫、昆虫与植物之间的联系很大程度上也是依赖化学物质传递信息,如昆虫求偶、寻找食物、定向栖息搜索寄主,受到侵扰时向同类告警等行为都存在 According to the progress of insect hormones, the basic can be divided into two categories: one is the hormone, mainly secreted by the insect endocrine organs, can flow in the body fluid active substance, which can regulate and control insect growth, Development, metamorphosis, diapause, mating, reproduction and general physiological metabolism. The other is pheromones, which are secreted by an organ or tissue of an insect and are active substances that flow outside the body. They can be spread to the outside world by air or other vehicles and affect other individuals of the same (and sometimes heterologous) species Special behavior. In recent years, there have been significant developments in ecology. People have conducted extensive studies on the formation of interrelations between organisms in the field of chemical ecology and found that certain chemical substances play an important role. Insects and insects, insects and plants are also largely dependent on chemical substances to transmit information, such as insect courtship, looking for food, habitat search for host orientation, in the event of intrusion to the same type of alarm exist
