Characterization of Neutral Lipase BT-1 Isolated from the Labial Gland of Bombus terrestris Males
BACKGROUND In addition to their general role in the hydrolysis of storage lipids, bumblebee lipases can participate in the biosynthesis of fatty acids that serve as precursors of pheromones used for sexual communication. RESULTS We studied the temporal dynamics of lipolytic activity in crude extracts from the cephalic part of Bombus terrestris labial glands. Extracts from 3-day-old males disp...
متن کاملComposition of the labial gland secretion of the bumblebee males Bombus pomorum.
Labial gland secretions of 22 males of the bumblebee Bombus pomorum, collected in the Czech Republic, were analysed separately for each individual. The secretions contained 70 compounds among which saturated and unsaturated hydrocarbons strongly dominated. The proportion of hydrocarbons in the secretion was unusually high (85-100%) compared to other bumblebee species studied so far (3-15%). Met...
متن کاملAnalysis of the labial gland secretions of the male bumblebee Bombus griseocollis (Hymenoptera: Apidae).
The labial gland secretions from males of the bumblebee Bombus (Separatobombus) griseocollis De Geer, a bumblebee exhibiting perching behaviour, were analysed by gas chromatography/mass spectrometry (GC/MS) in the electron impact and positive ion chemical ionization mode. The major compound of the complex mixture of alkenols, acetates, hydrocarbons, wax type esters and steroids is tetradecyl ac...
متن کاملSpatial Vision in Bombus terrestris
Bombus terrestris is one of the most commonly used insect models to investigate visually guided behavior and spatial vision in particular. Two fundamental measures of spatial vision are spatial resolution and contrast sensitivity. In this study, we report the threshold of spatial resolution in B. terrestris and characterize the contrast sensitivity function of the bumblebee visual system for a ...
متن کاملidentification and analysis of the male labial gland secretions of three species of bombus (thoracobombus) (hymenoptera: apidae)
the males of the three species of bumblebees, bombus (thoracobombus) ruderarius (müller), b. (t.) persicus radoszkowskiand b. (t.) mesomelas gerstaecker collected from vikan village, qazvin province and their male labial gland secretions were analyzed by gas chromatography/ mass spectrometry (gc/ms) and components of their extracts were identified. the major compounds were a complex mixture of ...
