标 题:Pesticidal activity of functionalized alkenes
发明人：LINDERMAN RUSSELL J
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides non-peptide organic compounds that have a structure analogous to or reminiscent of the TMOF structure and have pesticidal activity. Thus the present invention concerns pesticidal compounds that inhibit digestion in pests by terminating or otherwise blocking synthesis of digestive enzymes by activating a TMOF receptor (collectively referred to herein as “pesticidal compoundsâ€?). The pesticidal compounds and other compounds of the present invention are usefully employed in the control of pests, particularly insect pests such as mosquitoes, which ingest blood.

标 题 :Insecticide and acaricide paints that inhibit chitin synthesis, regulate insect juvenile hormone and repel arthropods, for controlling endemic diseases, pests and allergens
发明人：MATEO HERRERO MARIA PILAR

摘要:The present invention relates to insecticide and acaricide paints that inhibit chitin synthesis, regulate insect juvenile hormone and repel arthropods, for controlling endemic diseases, pests and allergens. The paints comprise at least the following compounds (in any combination): 1%-100% water, 0.0001%-20% insecticides, 0.0001%-20% chitin inhibitor, 0.0001%-20% juvenile hormone regulator, 1%-50% polymers, 0%-40% pigments, 0%-60% fillers, 0%-60% natural repellents, and 0.01%-20% stabilizers. The composition of the paints allows the active ingredients to be encapsulated in an aqueous polymer with or without the incorporation of fillers and pigments, and therefore the range of use thereof is increased.
