Robust olfactory responses in the absence of odorant binding proteins
eLife, 2019 Odorant binding proteins (Obps) are expressed at extremely high levels in the antennae of insects, and have long been believed essential for carrying hydrophobic odorants to odor receptors.

Insect Science, EarlyView.In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.

Organization and function of Drosophila odorant binding proteins
eLife, 2016 Odorant binding proteins (Obps) are remarkable in their number, diversity, and abundance, yet their role in olfactory coding remains unclear. They are widely believed to be required for transporting hydrophobic odorants through an aqueous lymph to ...

Ethology, EarlyView.Sexual dimorphism and stress‐induced stridulatory responses in Jaguajir rochae (Borelli, 1910). Females exhibited greater absolute pectinal size and higher sound pressure levels, whereas males showed higher pectinal allometric ratios relative to body size, lower sound frequencies, and shorter delta times.

OBSERVATION ON A NEW SENSILLUM of CERCI of PERIPLANETA AMERICANA BY SCANNING ELECTRON MICROSCOPY [PDF]
, 1994 作者在扫描电镜下观察了美洲大蠊尾须的细微结构，首次发现尾须上有1种新型感受器（简称感器）。该感器基部为1倒扣的飞盘形，其中部着生1根细长的感受器毛（简称感毛），暂名矛形感器。此外，尾须上还可见大量刺形感器b和少量钟形感器This paper deals with the morphology of the cerci of Periplaneta americana under the scanning electron microscope.In this initial study a new ...

Transcuticular calcium imaging as a tool for the functional study of insect odorant receptors
Frontiers in Molecular Neuroscience, 2023 The primary actors in the detection of olfactory information in insects are odorant receptors (ORs), transmembrane proteins expressed at the dendrites of olfactory sensory neurons (OSNs). In order to decode the insect olfactome, many studies focus on the

Distinctive gene expression in the reduced first thoracic legs of a nymphalid butterfly
Insect Molecular Biology, EarlyView.Transcriptome analysis reveals that the small non‐walking front legs of a butterfly have distinct gene expression to the four walking legs. Reduced front legs express a gene with putative mechanosensory roles, a blue‐sensitive opsin and two homeobox genes.

Frontiers in Ecology and Evolution, 2014 In Lepidoptera, the behavior of caterpillars to plant odors is poorly known. However, caterpillars are equipped with a reduced number of olfactory sensilla (3 on the antenna and 4-5 on the maxillary palps) which they can use to make fine discrimination ...
