Patent number: 10709140Abstract: 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.Type: GrantFiled: March 6, 2018Date of Patent: July 14, 2020Assignee: The University of The West IndiesInventors: Trevor Herbert Yee, Charah Tabetha Watson, Eric Garraway, Dwight Robinson, Nemoi Nastassia Sri Garcia Chisholm

Patent number: 10570110Abstract: 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.

Patent number: 10362781Abstract: 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.Type: GrantFiled: July 16, 2015Date of Patent: July 30, 2019Assignee: University of the West Indies, a Regional Institution, established by Royal CharterInventors: Trevor Herbert Yee, Charah Tabetha Watson, Eric Garraway

Patent number: 9971929Abstract: A fingerprint classification system and method for extracting the dominant singularity from a fingerprint image are described. The fingerprint classification system and method receive as an input a digital fingerprint image and the image is preprocessed to generate an enhanced and more accurate image. Feature pattern calculations are performed on the updated image to generate an Orientation Feature Vector. The Orientation Feature Vector is processed using a Regular Expression Machine classifier prediction model to generate a class label for the digital fingerprint image that was input.Type: GrantFiled: January 27, 2017Date of Patent: May 15, 2018Assignee: University of The West IndiesInventors: Laurice Phillips, Margaret Bernard, Duc The Kieu
