  • Pine shoot beetle attractant compositions
    Patent number: 6203786
    Abstract: Compositions of &agr;-pinene in combination with at least one of &agr;-pinene oxide, myrtenol and nonanal are disclosed. In a preferred embodiment, the composition containing &agr;-pinene and &agr;-pinene oxide may additionally include trans-verbenol. A lure for Tomicus piniperda is made up of one or more release devices which dispense &agr;-pinene and at least one of &agr;-pinene oxide, myrtlenol nonanal and trans-verbenol.

  • Cockroach attractant
    Patent number: 5505951
    Abstract: Compounds useful as cockroach attractants, the synthesis of the compounds, and methods of controlling cockroach populations with the compounds are disclosed. The compounds are pyrans having the formula: ##STR1## wherein: R.sup.1 is a methyl, ethyl, propyl, or methoxy group andR.sup.2 is a branched alkyl side chain having from 7 to 11 carbons. Preferably, R.sup.2 is a 2,4-dimethyl-substituted alkyl group. Most preferably R.sup.1 is methyl and R.sup.2 is 2,4-dimethylheptanyl. The pyrans can be used as an attractant in cockroach traps comprising, in addition to a pyran according to Formula (I) above, a support and a cockroach restraint. Alternatively, the pyran of the present invention can be combined with a biocontrol agent or an insecticide to form a cockroach control composition.
