Identification of the cuticular hydrocarbons of the horn fly and assays for attraction.

摘要: Horn fly cuticular paraffin and monoolefin hydrocarbons were chemically identified assayed for biological activity as attractants. The majority of the paraffins odd-numbered, straight-chain molecules 21–29 carbons in length; much smaller amounts even-numbered, straightchain 22–28 length methyl-branched compounds also present. At least 80% consisted 23, 25, 27 length, two which have been sex pheromones other muscoid species. hydrocarbon profiles among sexes strains (laboratory wild) very similar except wild females, showed quantitative differences from sources. However, only females significant (albeit low) responses to some test materials, both synthetic natural, appeared be centered monoolefins.
