ABSTRACT:
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.
