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. An example of a useful compound is 5-methyl-7-ethoxy-2,2-dimethyl-3-chromene. 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 to an incompetant precocious adult. Additional effects which have been obtained include sterilization of mature insects.
本发明公开了一种具有杂环酮结构的潜在昆虫控制化合物,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来有效控制昆虫。一个有用的化合物的例子是5-甲基-7-乙氧基-2,2-二甲基-3-杂环酮。这些化合物作用于诱导不成熟昆虫的早熟,导致在蜕皮为无能早熟成虫期间或之前或之后的短时间内死亡。已获得的其他效果包括成熟昆虫的不育。
