A01N 2524

US Classification:

424 84

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 and R. 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.

International Classification:

A01N 2500

US Classification:

424 84

Abstract:

Compositions of. alpha. -pinene in combination with at least one of. alpha. -pinene oxide, myrtenol and nonanal are disclosed. In a preferred embodiment, the composition containing. alpha. -pinene and. alpha. -pinene oxide may additionally include trans-verbenol. A lure for Tomicus piniperda is made up of one or more release devices which dispense. alpha. -pinene and at least one of. alpha. -pinene oxide, myrtlenol nonanal and trans-verbenol. A method for attracting pine shoot beetles, Tomicus piniperda, uses the composition disclosed, optionally as part of a trap.
