METHODS OF CONTROLLING THE BREEDING BEHAVIOR OF BUTTERFLIES

Methods of controlling the feeding and/or breeding behavior of a target insect are disclosed in which a host plant is provided a substantial distance from a plant of interest, chemical attractant that induces the target insect to lay eggs on the host plant is applied to the host plant, application of the chemical attractant to the host plant is repeated as required to induce residual target-insect populations to lay eggs on the host plant, and wherein the behavior is controlled when a substantial number of offspring belonging to subsequent generations themselves mature and display a preference for laying eggs on the same type of host plant on which they were reared without further application of the chemical attractant is provided. Also disclosed are methods of deterring target insect feeding and breeding on plants of interest by applying toxic plant extract to the plants of interest.

METHODS AND PRODUCTS FOR REDUCING THE POPULATION SIZE OF PAPILIO DEMOLEUS L. (PAPILIONIDAE)

The methods, kits, and products for controlling a target insect population are disclosed in which a non-host plant containing a toxin and a chemical attractant known to attract the target insect is treated with chemical attractant from a plant of interest. The chemical attractant induces the target insect to lay eggs on the non-host plant. The resulting offspring die of starvation from refusing to feed on the non-host plant. The non-host plant and plant of interest contain at least one common chemical. The methods, kits, and products for controlling a target insect population using an extract from a non-host plant are also disclosed. The non-host plant extract is applied to the plant of interest, and when ingested or applied directly to the target insect, kills the target insect or causes it to develop with deformities.

Methods of controlling the breeding behavior of butterflies

Methods of controlling the feeding and/or breeding behavior of a target insect are disclosed in which a host plant is provided a substantial distance from a plant of interest, chemical attractant that induces the target insect to lay eggs on the host plant is applied to the host plant, application of the chemical attractant to the host plant is repeated as required to induce residual target-insect populations to lay eggs on the host plant, and wherein the behavior is controlled when a substantial number of off-spring belonging to subsequent generations themselves mature and display a preference for laying eggs on the same type of host plant on which they were reared without further application of the chemical attractant is provided. Also disclosed are methods of deterring target insect feeding and breeding on plants of interest by applying toxic plant extract to the plants of interest.

Process to extract quassinoids

A means for the extraction and crystallization of quassinoids such as quassin and neoquassin from natural sources containing these compounds, using compounds that are Generally Recognized As Safe by the U.S. Food and Drug Administration is provided. In particular, a means for extraction that does not require use of lead acetate, chloroform, methanol, or diethyl ether is provided. The process includes a means of removing non-polar and very polar substances from an extracted residue to enhance crystallization of quassinoids from the residue.

SIMPLIFIED PROCESS TO EXTRACT QUASSINOIDS

Improved processes for the extraction of quassinoids such as quassin and neoquassin from natural substances containing these compounds are described. The process uses compounds that are Generally Recognized As Safe by the U.S. Food and Drug Administration. In a first embodiment, the process includes a sonication method using water and no organic solvent. The process is highly efficient and comprises fewer steps than other processes known in the art. In a second embodiment, a method of extracting quassinoids from natural substance comprising bark of a plant of the plant family Simaroubaceae is also disclosed. In a third embodiment, indirect sonication of quassinoids is described using a mixture of polar and non-polar organic solvents.
