Sex-specific genetic differentiation and coalescence times: estimating sex-biased dispersal rates.

abstract：:Biological control requires specific tools for the accurate detection and identification of natural enemies, and to detect unusual variations in their density, which may follow changes in agricultural practices. Here we have developed specific molecular markers to detect Lydella thompsoni (Herting) and Pseudoperichaet...
