Traps baited with floral chemicals on the island of Hawaii captured several pest moth species. Chrysodeixis eriosoma (Doubleday)(green garden looper), Autographa biloba (Doubleday)(bi-lobed looper), and Mythimna unipuncta (Haworth)(true armyworm), all Noctuidae, as well as Hymenia recurvalis (L.)(beet webworm), a Crambidae, were trapped with phenylacetaldehyde (PAA). There was no response by moths to beta-myrcene (BM), methyl salicylate (MS), cis jasmone (CJ), methyl-2-methoxy benzoate (MMB), 2-phenylethanol (2PE), or linalool (LIN) when these chemicals were tested singly. When other floral chemicals were presented in traps with PAA, numbers of C. eriosoma captured were increased by BM, MS, 2PE or MMB. Numbers of A. biloba and Peridroma saucia (Hubner)(variegated cutworm) were increased by adding BM with PAA in traps. Numbers of M. unipuncta were increased by BM or 2PE, and numbers of H. recurvalis were increased by MMB or LIN, presented with PAA. Both sexes of these five speciees of moths were trapped with floral lures, most females captured were mated, and many females possessed mature eggs.
