 Title    Bestimmung der relativen Flüchtigkeit von Sexualpheromonen von Schmetterlingen mittels Closed Loop Stripping* Determination of Relative Volatility of Lepidoptera Sex Pheromones by Closed Loop Stripping  
 Abstract    By means o f closed loop Stripping the relative evaporation rates o f monounsaturated C U)-C|6-acetates and C l(l-C12-alcohols have been determined. The results o f stimulus released demonstrate the different volatilities of pheromone compounds which should be taken in ac­ count with certain biotests and physiological studies.

 Title    Direct Measurement of the Flight Behavior of Male Moths to Calling Females and Synthetic Sex Pheromones  
 Abstract    The approach of male Lobesia botrana (Lepidoptera: Tortricidae) in the wind tunnel to a source of sex pheromone was studied using two video cameras connected to image processing equipment. Three-dimensional records demonstrate that the flight to calling females is quite direct compared to the zigzag flight reported for other species. Convoluted paths displaying bimodal distribution of track and course angles were only obtained with a synthetic phero­ mone blend consisting of £'-7,Z-9-dodecadienyl acetate, £'-7,Z-9-dodecadien-l-ol and Z-9-dodecenyl acetate at the proportions of 1 /0.2/0.05. This suggests that this blend is still subopti-mal and that zigzag flight may be due to a lack of precision in upwind motion caused by inade­ quate composition of the stimulus.
