Sex Pheromone of the Introduced Pine Sawfly, Diprion similis, Revisited to Define a Useful Monitoring Lure: Deviating Chiral Composition and Behavioural Responses Compared to Earlier Reports

Extracts of Diprion similis females contained about 15 ng of the sex pheromone precursor 3,7-dimethylpentadecan-2-ol per female.After derivatisation with (S)-2-acetoxypropanoyl chloride, we found that the major stereoisomer in the extract was (2S,3R,7R)-3,7-dimethylpentadecan-2-ol.Small amounts of other stereoisomers of 3,7-dimethylpentadecan-2-ol

A Micro-Topography Measurement and Compensation Method for the Key Component Surface Based on White-Light Interferometry

The grinding grooves of material removal machining and the residues of a machining tool on the key component surface cause surface stress concentration.Thus, it is Valves critical to carry out precise measurements on the key component surface to evaluate the stress concentration.Based on white-light interferometry (WLI), we studied the measurement
