Antennae of five male butterflies namely Danaus chrysippus (Linnaeus) (Danaidae), Pontia daplidice moorie (Rober) (Pieridae), Junonia lemonias (Nymphalidae), Chilades pandava Horsfield (Lycaenidae) and Papilio demoleus Linnaeus (Papilionidae) have been studied under scanning electron microscope for observing the type number sensilla dispersed on their component segments i.e. Scape, Pedicel Flag...

Electrophysiological recordings have been made from cells in the eight large, labellar sensilla of g. morsitans. One of these cells in each sensillum was shown to respond to ATP over a concentration range of 10(-6)-10(-3) M. It was also sensitive to several other adenosine phophates, but much less sensitive to CTP, GTP and ITP. The activity of the receptor was depressed below pH 7, and sometime...

The aim of this study is to describe a new species of the costata-group from Brazil. Alona margipluma sp. nov. shares morphological traits with A. costata Sars, 1862, A. natalensis Sinev, 2008, and A. cheni Sinev, 1999, but differs from them in: (i) thin setulae between the marginal setae on the valves, (ii) setae 4-5 on the exopodite of limb III long and different in length, (iii) bottle-shape...

The biophysical properties of sensory neurons are influenced by their morphometric and morphological features, whose precise measurements require high-quality volume electron microscopy (EM). However, systematic surveys nanoscale characteristics for identified scarce. Here, we characterize the morphology Drosophila olfactory receptor (ORNs) across majority genetically hairs. By analyzing serial...

Lutzomyia longipalpis adult males form leks on or near hosts and release (1S,3S,7R)-3-methyl-alpha-himachalene from their tergal glands to lure females to the same site for mating and feeding. Here we have examined whether the male-produced attractant could also serve as a male aggregation stimulus. High resolution chiral capillary gas chromatography analysis of male tergal gland extracts, synt...
