Courtship pheromones in parasitic wasps: comparison of bioactive and inactive hydrocarbon profiles by multivariate statistical methods.

abstract：:An inexpensive, silent, maintenance-free suction/adsorption system is described for efficiently collecting submicrogram quantities of odors over a wide range of volatilities under field conditions. The samples can later be submitted to gas chromatographic-mass spectrometric analyses. An example is given with odors sam...
