Pollination based on insect deception has been debated in the scientific community since it was first reported over two hundred years ago. A vast majority of deceptive syndromes occur within the orchid family. While many cheating flowers have been described and are well known, there are still many curious cases that need further investigation. One prime example of such a case is Cypripedium calceolus, known as European lady’s slipper orchid. While the flower has been of interest to many prominent scientists for over a century, its pollination is still not fully understood. Both visual and olfactory cues seem to play an important role in pollinator attraction. In this study we focussed on the olfactory cues in order to explore their relationship (in future... |

Foram avaliados os quatro componentes sintéticos identificados no feromônio sexual da broca-pequena-do-tomate, Neoleucinodes elegantalis Guenée (BPT): (E)-11-hexadecenol (E11-16:OH), (Z)-11-hexadecenol (Z11-16:OH), (E)-11-hexadecenal (E11-16:Al) e (E)-11-Acetato de hexadecenila (E11-16:OAc). Testes de campo foram realizados com armadilhas objetivando identificar o composto mais eficaz na captura de machos do inseto e determinar o efeito de concentrações do isômero Z11-16:OH, em mistura com o componente mais eficaz na captura de machos. Em laboratório, foram realizados testes eletrofisiológicos com eletroantenógrafo para monitorar as respostas da antena de machos de N. elegantalis a diferentes concentrações dos componentes. E11-16:OH, na concentração de 100... |
