No presente trabalho, que tem por finalidade contribuir para uma melhor compreensao da ictiofaunula do Cretaceo da Chapada do Araripe, no Nordeste do Brasil, o genero Tharrhias e reestudado, dando-se a diagnose definida. E esclarecida a sua posicao taxionomica entre os Chanidae e a inter-relacao com os demais generos dessa familia, especialmente as formas fosseis, do Cretaceo. O problemas da validade das especies Tharrhias rochae (Jordan & Branner 1908) e Tharrhias araripis e analisado apos o estudo das mesmas, baseado em material das colecoes paleoictiologicas do Departamento Nacional da Producao Mineral. Ambas as especies sao consideradas validas do ponto de vista taxionomico, sendo redescritas e recebendo nova caracterizacao. Num exame, das condicoes de deposicao dos sedimentos da Chapada do Araripe, focalizou-se o sistema de vida que possivelmente tiveram esses Chanidade, e a razao do elevado numero de fosseis desses peixes, encontrados em alguns ictiolitos da Formacao Santana. |

The cotton aphid, Aphis gossypii (Homoptera: Aphididae), is increasing in importance as a pest worldwide since the introduction of Bt-cotton, which controls lepidopteran but not homopteran pests. The chemical ecology of interactions between cotton, Gossypium hirsutum (Malvaceae), A. gossypii, and the predatory lacewing Chrysoperla lucasina (Neuroptera: Chrysopidae), was investigated with a view to providing new pest management strategies. Behavioral tests using a four-arm (Pettersson) olfactometer showed that alate A. gossypii spent significantly more time in the presence of odor from uninfested cotton seedlings compared to clean air, but significantly less time in the presence of odor from A. gossypii infested plants. A. gossypii also spent significantly more time in the presence of headspace samples of volatile organic compounds (VOCs) obtained from uninfested cotton seedlings, but significantly less time with those from A. gossypii infested plants. VOCs from uninfested and A. gossypii infested cotton seedlings were analyzed by gas chromatography (GC) and coupled GC-mass spectrometry (GC-MS), leading to the identification of (Z)-3-hexenyl acetate, (E)-4,8- dimethyl-1,3,7-nonatriene (DMNT), methyl salicylate, and (E,E)-4,8,12-trimethyl-1,3,7,11-tridecatetraene (TMTT), which were produced in larger amounts from A. gossypii infested plants compared to uninfested plants. In behavioral tests, A. gossypii spent significantly more time in the control (solvent) arms when presented with a synthetic blend of these four compounds, with and without the presence of VOCs from uninfested cotton. Coupled GC-electroantennogram (EAG) recordings with the lacewing C. lucasina showed significant antennal responses to VOCs from A. gossypii infested cotton, suggesting they have a role in indirect defense and indicating a likely behavioral role for these compounds for the predator as well as the aphid.
