Cell and Tissue Research (331)3 2008
Abstract
The organization of the antennal muscles, nerves, and motor neurons has been investigated in the cockroach, Periplaneta americana. Antennal movements have been observed by video analysis, muscle actions have been determined by dissection and direct mechanical testing, and the motor neurons innervati...

Current Biology (18)4 2008
Abstract
A recent study has shown that, unusually, both the sensory and motor capabilities of an electric fish are omnidirectional. This matching of motor and sensory spaces helps the fish to hunt prey efficiently - particularly important given their energetically costly active sensory system.

Current Biology (18)3 2008
Abstract
The ability to sense dry or moist air - hygrosensation - is conserved widely, but the underlying mechanisms are obscure. A recent study has shown that TRP channels are required for hygrosensation in Drosophila, further expanding the repertoire of sensory modalities mediated by TRP channels.

Abstract
In the caddisfly Molanna angustata, females produce a sex pheromone in glands with openings on the fifth sternite. Gas chromatographic analyses of pheromone gland extracts with electroantennographic detection revealed four major compounds that stimulated male antennae. These compounds were identifie...

Abstract
We tested the hypothesis that, as an extreme specialist, M. mutabilis should respond to cues derived from its host rather than from its microenvironment, a phenomenon that has hitherto only been addressed in the context of herbivorous insects and their parasitoids. In behavioral assays, M. mutabilis...

Abstract
We employed differential library screening of an albumen gland cDNA library, RT-PCR, recombinant protein expression, rhinophore contraction bioassays and immunocytochemistry. Alb-1 is expressed in the Aplysia californica albumen gland and encodes a novel protein that does not share significant seque...

Zoological Science (25)2 2008
Abstract
We found sexual dimorphism of the antennal lobe glomeruli in carpenter ants, Camponotus japonicus. Female workers and unmated queens had about 430 glomeruli, the highest number reported so far in ants. Males had a sexually dimorphic macroglomerulus and about 215 ordinary glomeruli. This appeared to...

Abstract
We provide the first detailed structure-function analyses within an ant's central olfactory system asking whether in the carpenter ant, Camponotus floridanus, the olfactory pathway exhibits adaptations to processing many pheromonal and general odors. Using fluorescent tracing, confocal microscopy, a...

Abstract
We applied them to the study of Anopheles gambiae antennae, with the aim of analysing expression of soluble proteins involved in olfaction perireceptor events. MALDI spectra obtained by direct profiling on single antennae and by the analysis of extracts, showed similar profiles, although spectra obt...

Abstract
While testing traps baited with a blend of geranyl octanoate and geranyl butanoate (pheromone components previously identified for Agriotes lineatus, Coleoptera, Elateridae) in Portugal and Bulgaria, large numbers of the closely related Agriotes proximus were captured. In the literature, two differe...

Abstract
Inflorescence scent samples from nine populations of dioecious Silene otites, a plant pollinated by moths and mosquitoes, were collected by dynamic headspace extraction. Sixty-three scent samples were analyzed by gas chromatography-mass spectrometry. Out of 38 found, 35 compounds were identified, mo...

Abstract
The pectines of a new-world scorpion were studied as to their sensilla, nerve supply, and central nervous projections. (i) Pectines and sensilla in Vaejovis are similar to those examined in old-world species previously, although Vaejovis' pectines are larger and equipped with more receptors. The spe...

Abstract
Solifugae possess an evertable, adhesive pedipalpal organ (suctorial organ) at the tip of the distal tarsus of each pedipalp that is unique among arachnids. When inverted inside the pedipalp, the suctorial organ is covered with two cuticular lips, a dorsal upper lip and a ventral lower lip, but it c...

Abstract
We demonstrate that highly conserved miRNA-183 orthologs exist in both deuterostomes and protostomes and their expression is predominant in ciliated ectodermal cells and organs. The miRNA-183 family members are expressed in vertebrate sensory hair cells, in innervated regions of invertebrate deutero...

Abstract
Here we show that membrane-bound DLK1 can regulate Notch leading to altered cellular distribution of Notch itself and inhibiting expression of Notch target genes. The resulting adult phenotypes are indicative of reduced Notch function and are enhanced by Notch mutations, confirming that DLK1 action...

Parazitologiya (42)4 2008
Abstract
The main complication sensory organs (the palpal organ and the tarsal sensory complex) of several species of gamasid mites were studied in scanning electron microscope. The species examined included permanent ectoparasites (Laelaps agilis, Laelaptidae), parasites of the nasal cavity and respiratory...

Biosystems (94)1-2 2008
Abstract
We discuss a rule proposed by the biologist Thomas according to which the possibility for a genetic network (represented by a signed directed graph called a regulatory graph) to have several stable states implies the existence of a positive circuit. This result is already known for different models,...

Mechanisms of Development (125)1-2 2008
Abstract
We show here that Dip3, a transcription factor required for eye development, alters fate determination when misexpressed in the early eye-antennal disc, and have taken advantage of this observation to gain new insight into the mechanisms controlling the eye-antennal switch. Dip3 misexpression yields...

Mechanisms of Development (125)3-4 2008
Abstract
We have recently shown that the Drosophila Abi is capable of promoting bristle development in a wasp dependent fashion. Here, we report that Drosophila Abi induces sensory organ development by modulating EGFR signaling. Expression of a membrane-tethered activated Abi protein (Abi(Myr)) leads to an i...

Abstract
The external morphology of the adult female blow fly, Chrysomya pinguis (Walker, 1858), was examined using scanning electron microscopy. Ultrastructure of the compound eye, ocellus, antenna, palpus, spiracles and portions of the thorax was highlighted. A great difference was observed in sculpture pa...

A fully automated procedure to extract and to image local fibre orientation in biological tissues from scanning X-ray diffraction is presented. The preferred chitin fibre orientation in the flow sensing system of crickets is determined with high spatial resolution by applying synchrotron radiation b...

We demonstrated that an invertebrate can be repulsed or attracted by the same natural odour at the same time and that these behavioural responses are likely aimed at achieving different physiologically relevant goals....
