Response of Diabrotica speciosa (Coleoptera: Chrysomelidae) to 1,4-dimethoxybenzene and analogs in common bean crop
Several synthetic and commercial analogs of 1,4-dimethoxybenzene, a kairomone of Diabrotica speciosa, along with other compounds already shown to be attractive to other species of Diabrotica, were tested as attractant to D. speciosa. Yellow cup traps were lured with the compounds and installed in a...

| description | Several synthetic and commercial analogs of 1,4-dimethoxybenzene, a kairomone of Diabrotica speciosa, along with other compounds already shown to be attractive to other species of Diabrotica, were tested as attractant to D. speciosa. Yellow cup traps were lured with the compounds and installed in a common bean field. Assessments were conducted 24 h later. 1,4-dimethoxybenzene lured traps caught significantly more beetles than the control traps. Captures of traps lured with 1,4-dimethoxybenzene analogs did not differ from the control traps. Results showed that position and nature of the substituents on the aromatic ring played a crucial role in the activity of the natural compound. The aromatic ring was also very important to the activity of the kairomone.<br>Uma série de compostos, sintéticos e comerciais, análogos ao 1,4-dimetoxibenzeno, um cairomônio de Diabrotica speciosa, juntamente com outros compostos comerciais atrativos para outras espécies de Diabrotica, tiveram suas atividades testadas frente à D. speciosa. Armadilhas de copos amarelos contendo os compostos foram instaladas em plantação de feijão. As avaliações foram realizadas 24 horas depois. Armadilhas com 1,4-dimetoxibenzeno capturaram significativamente mais insetos do que armadilhas testemunha. Armadilhas com análogos do 1,4-dimetoxibenzeno não capturaram mais insetos que as armadilhas testemunha. Os resultados mostraram que a posição e a natureza dos substituintes, juntamente com a aromaticidade verificada na estrutura do composto natural, são cruciais para a atratividade. |
