Publication number: 20210244023Abstract: The present invention relates to compositions of microencapsulated organic compounds, such as pesticides, including insecticides, and methods of making and using the microcapsules. Encapsulating materials include proteins and degradable polymers. These microencapsulated organic compounds provide, for example, increased effective working time of pesticides, resulting in lowered need for reapplication of the pesticides.Type: ApplicationFiled: June 5, 2019Publication date: August 12, 2021Inventors: Sanghoon KIM, Patrick F.

Patent number: 8334366Abstract: Lycotoxin-1 peptide mutant peptides which exhibit increased insecticidal activity are produced by substitution of both a proline for the lysine at amino acid position 24 and a tryptophan for the leucine at amino acid position 25 of the wild-type amino acid sequence for lycotoxin-1. Further substitution of amino acids 8, 9 or 10 of the lycotoxin-1 wild-type amino acid sequence, specifically substituting a histidine for the phenylalanine at amino acid position 8, a glutamine for the glycine at amino acid position 10, or a serine for the leucine at amino acid position 9, provides an even greater increase in insecticidal activity. In addition to changes in the lycotoxin-1 amino acid sequence, the addition of an enterokinase K recognition site, DDDK, to the N-terminus of the lycotoxin-1 peptide increases insecticidal activity further still.Type: GrantFiled: April 29, 2010Date of Patent: December 18, 2012Assignee: The United States of America, as represented by the Secretary of AgricultureInventors: Stephen R. Hughes, Patrick F. Dowd

Patent number: 5081788Abstract: An insect trap for attracting and capturing flying insects. The apparatus includes a chamber for holding an insect attractant and exposing the same to a current of air, and having a first opening allowing passage of air but not insects therein. Positioned opposite the first opening, at least one funnel-shaped entrance to the chamber allows entry of the insects into the trap, as well as passage of air currents and entrained attractant odors out of the trap. An insect collection container, optionally having a one-way entrance, is also provided, and communicates with the chamber through a second chamber opening and the one-way entrance. Proper orientation of the trap in the wind is achieved by mounting a wind vane or fins onto the exterior of the chamber so as to position the first opening upwind, and the funnel-shaped entrance to the chamber downwind from the first opening.Type: GrantFiled: May 1, 1991Date of Patent: January 21, 1992Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Patrick F.

Patent number: 5011683Abstract: A male-produced aggregation pheromone was demonstrated in Carpophilus hemipterus (L.) (Coleoptera: Nitidulidae) using a wind-tunnel bioassay. The attractiveness of the pheromone is greatly enhanced by volatiles from a host plant, and combinations of pheromone and food volatiles typically attract 3-10 times more beetles than either source by itself. The pheromone consists of a series of 13-, 14-, and 15-carbon unsaturated hydrocarbons, the most abundant of which is 3,5,7-trimethyl-(E,E,E,E)-2,4,6,8-decatetraene.Type: GrantFiled: November 25, 1988Date of Patent: April 30, 1991Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Robert J.

Patent number: 5008478Abstract: Male-produced aggregation pheromones were demonstrated in Carpophilus hemipterus (L.), Carpophilus lugubris Murray, and Carpophilus freemani Dobson (Coleoptera: Nitidulidae) using a wind-tunnel bioassay. The attractiveness of the pheromones is greatly enhanced by volatiles from a host plant, and combinations of pheromone and food volatiles typically attract 3-10 times more beetles than either source by itself. The pheromones consist of a series of 12-, 13-, 14-, and 15-carbon unsaturated hydrocarbons. The most abundant of these in C. hemipterus is (2E,4E,6E,8E)-3,5,7-trimethyl-2,4,6,8-decatetraene. In C. lugubris, the most abundant is (2E,4E,6E,8E)-7-ethyl-3,5-dimethyl-2,4,6,8-undecatetraene, and in C. freemani, (2E,4E,6E)-5-ethyl-3-methyl-2,4,6-nonatriene.Type: GrantFiled: July 31, 1989Date of Patent: April 16, 1991Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Robert J.
