The Crystal Structure of a Cockroach Pheromone-binding Protein Suggests a New Ligand Binding and Release Mechanism*
Pheromone-binding proteins (PBPs) are small helical proteins found in sensorial organs, particularly in the antennae, of moth and other insect species. They were proposed to solubilize and carry theExpand
Chemistry of defensive secretions in nymphs and adults of fire bug,Pyrrhocoris apterus L. (Heteroptera, Pyrrhocoridae)
The defensive secretions from the nymphs and the adults of both sexes inP. apterus were chemically investigated. Forty components were identified from the nymphal posterior dorsoabdominal glands andExpand
Defensive secretions of nymphs and adults of five species of Pyrrhocoridae (Insecta: Heteroptera)
Abstract The chemical composition of the defensive secretions of the nymphs and the adults of Dysdercus fasciatus was investigated. Thirty compounds were identified from the nymphal posteriorExpand
Chemistry of pheromonal and defensive secretions in the nymphs and the adults ofDysdercus cingulatus Fabr. (Heteroptera, Pyrrhocoridae)
The exocrine secretions from the nymphs and the adults of both sexes inD. cingulatus were chemically investigated. Seven compounds were identified in the anterior glands, and eleven in the medianExpand
What does Cryptocercus kyebangensis, n.sp. (Dictyoptera: Blattaria: Polyphagidae) from Korea reveal about Cryptocercus evolution? A study in morphology, molecular phylogeny, and chemistry of tergal
Abstract The description of a new species of the woodroach Cryptocercus kyebangensis Grandcolas from South Korea offers the opportunity to bring comparative information within the genus. ThisExpand
A pheromone-binding protein from the cockroach Leucophaea maderae: cloning, expression and pheromone binding.
Odorant-binding proteins (OBPs) are thought to transport volatile compounds from air to their receptors through the sensillary lymph. In this protein family, the subgroup of pheromone-bindingExpand
Changes of species specific cuticular hydrocarbon profiles in the cockroaches Nauphoeta cinerea and Leucophaea maderae reared in heterospecific groups
The cuticular hydrocarbon profiles of the cockroaches Nauphoeta cinerea and Leucophaea maderae are species‐specific when maintained in homospecific rearings. When individuals were reared in mixedExpand
Molecular characterization of Lma-p54, a new epicuticular surface protein in the cockroach Leucophaea maderae (Dictyoptera, oxyhaloinae).
The epicuticular surface protein Lma-p54 is imbedded in the "cuticular waxes" which cover the abdominal surface of the adult Leucophaea maderae. Natural Lma-p54 was purified and the complete cDNAExpand
The defensive secretion of Eurycotis floridana (Dictyoptera, Blattidae, Polyzosteriinae): Chemical identification and evidence of an alarm function
The defensive secretion of the cockroach Eurycotis floridana was believed to contain only (E)-2-hexenal. However, we have shown it consists of 40 components, of which 30 were tentatively identified.Expand
Calling behaviour of female Periplaneta americana: Behavioural analysis and identification of the pheromone source
Abstract The site for the production of Periplanone B, one of the components of the female sex pheromone of Periplaneta americana , was localized in glands situated in the genital atrium, and we haveExpand
