Patent number: 9185896Abstract: The present invention relates generally to polymer devices impregnated with semiochemical attractants for termites. The materials for delivering the semiochemicals are preferably cellulose-free. Devices of the subject invention are placed in soil and provide a slow-release and permeation of the semiochemicals into the adjacent soil so that termites tunneling in the vicinity are directed toward the chemical sources. Because the semiochemicals are impregnated in the polymer, the device also protects the semiochemicals so that they do not degrade rapidly under field conditions. In a preferred embodiment, the subject invention comprises a durable station housing, preferably with a removable bait, wherein the body of the station housing itself is impregnated with a semiochemical attractant.Type: GrantFiled: October 14, 2013Date of Patent: November 17, 2015Assignee: University of Florida Research Foundation, Inc.Inventor: Nan-Yao Su

Patent number: 8293797Abstract: The subject invention relates in part to the oral administration of ecdysteroids for controlling subterranean termites. Preferred ecdysteroids for use according to the subject invention are ecdysone, certain ecdysone analogs, and 20-hydroxyecdysone, for example. In some preferred embodiments, one or more of these compounds is used in a termite bait in combination with one or more chitin synthesis inhibitors. Thus, the subject invention also relates in part to controlling termites by the use of a chitin synthesis inhibitor (CSI), such as hexaflumuron and/or noviflumuron, together with an ecdysteroid (and analogs thereof) or molt-accelerating compound (MAC), such as halofenozide. The subject invention also relates to mixtures comprising these two active ingredients. The MAC/ecdysteroid analog induces a preliminary molting event in termite workers (they could not complete the molting), which then allows the CSI to further disrupt the molt and cause mortality.Type: GrantFiled: April 8, 2011Date of Patent: October 23, 2012Assignee: University of Florida Research Foundation, Inc.Inventors: Nan-Yao Su, James Edward King, Paul Allen Neese

In some preferred embodiments, one or more of these compounds is used in a termite bait in combination with one or more chitin synthesis inhibitors (CSI), such as hexaflumuron and/or noviflumuron. The subject invention also relates to mixtures comprising these two active ingredients. The ecdysteroid analog or molt-accelerating compound (MAC) typically induces a preliminary molting event in termite workers, which then allows the CSI to further disrupt the molt and cause mortality. The combination of these active ingredients, causing accelerated molting together with inhibition of chitin synthesis, is surprisingly shown herein to enhance activity against termites, as compared to either group of compounds alone.Type: GrantFiled: February 17, 2005Date of Patent: August 16, 2011Assignee: University of Florida Research Foundations, Inc.Inventors: Nan-Yao Su, James Edward King, Paul Allen Neese
