  • Patent number: 4656189
    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. 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.

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.

  • Patent number: 4540830
    Abstract: This invention relates to substituted isopentenyl phenyl compounds and their use as anti-juvenile hormones. The compounds have been found effective in the control of insects by inhibiting the actions of juvenile hormones. Such compounds act to induce precocious maturation of immature insects resulting in a reduction in the ecological impact of the insect. Additional effects which have been obtained include sterilization of mature insects. Based on previous research it is also believed these compounds will cause interruption of embryogenesis in insect eggs, the induction of diapause in insects and the prevention of sex pheromone secretion in insects.

  • Patent number: 4262271
    Abstract: An electromagnetic solenoid incorporating a plunger return mechanism comprising a spring retainer non-rotatably fitted to the plunger, and a spring held in compression between the retainer and a coil wound bobbin disposed about the plunger. The spring is held non-rotatable with respect to the bobbin and the plunger, and the plunger is non-rotatable with respect to the bobbin so that the spring cannot unwind with respect to the spring retainer.
