Dataset of seed infestation rates sampled on 32 sites from 1977 to 2010.

These data were entirely used for the descriptive analysis and partially used for parameter estimation. We indicated the year and the site of record, the number of cones sampled, the total number of seeds in cones, the number of parasitized seeds in cones, the global seed infestation rate, the total number of M. pinsapinis emerged, the total number of M. schimitscheki emerged, the contribution of M. pinsapinis and M. schimitscheki to the global SIR. The total number of adults emerged was observed from 1999 to 2007 and was estimated from diapause pattern for cohorts from 2008 to 2010.
