Potential insect control compounds which are chromenes, as well as their method of preparation and use, are disclosed. Compounds have been found which are effective in the control of insects by inhibiting the actions of juvenile hormone. Examples of useful compounds are 6,7-dimethoxy-2,2-dimethyl-3-chromene and 7-methoxy-2,2-dimethyl-3-chromene which can be extracted from the common bedding plant Ageratum houstonianum. Such compounds act to induce precocious maturation of immature insects, resulting in death either during or within a short time before or after the molting process. Additional effects which have been obtained include sterilization of mature insects, interruption of embryogenesis in insect eggs, the induction of diapause in insects and the prevention of sex pheromone secretion in insects.
揭示了一种潜在的昆虫控制化合物,即香豆素,以及它们的制备和使用方法。已发现这些化合物通过抑制幼虫激素的作用而对昆虫的控制有效。有用化合物的示例包括6,7-二甲氧基-2,2-二甲基-3-香豆素和7-甲氧基-2,2-二甲基-3-香豆素,可以从常见的床头植物蓝花艾格菊中提取。这些化合物作用于诱导不成熟昆虫的早熟,导致在蜕皮过程中或在蜕皮过程之前或之后的短时间内死亡。已获得的额外效果包括成熟昆虫的不孕化、昆虫卵的胚胎发育中断、昆虫的滞育诱导以及昆虫性信息素分泌的预防。
