Abstract

The relative responses of Diabrotica speciosa (Ger.) and Cerotoma arcuata tingomariana Bechyn (Coleoptera: Chrysomelidae) to traps baited with chemicals were studied. Volatile substances of Curcubita maxima Duchesne blossoms, other previously reported volatile attractants for Diabroticites and mixtures of chemicals were tested in common bean, Phaseolus vulgaris L., and soybean, Glycine max (L.) Mer., fields. Traps baited with 1,4-dimethoxybenzene caught 29.4 times more beetles than solvent controls in fields of soybeans, and 9.4 times more in common bean fields. Traps baited with VIP (veratrole + indole + phenylacetaldehyde) caught 6.5 times more beetles than solvent controls in soybean and 3.5 times more in common bean plots, whereas traps baited with TIC (1,2,4-trimethoxybenzene + indole + trans-cinnamaldehyde) caught 6.7 times more beetles in soybean and 3.5 times more in common bean plots. Volatile chemicals used in this study did not attract C. a. tingomariana. In a dose-response study, captures of D. speciosa increased significantly with increasing doses of 1,4-dimethoxybenzene.
