Effect of log seasonality on reproductive potential of Monochamus galloprovincialis reared in Scots pine logs under laboratory conditions

Insect reproduction may be affected by a number of factors including seasonal changes in larval or adult nutrition. The effect of season on the reproductive potential of Monochamus galloprovincialis (Olivier) females reared in Pinus sylvestris L. (Scots pine) logs was investigated by constructing fe...

Description
Summary:Insect reproduction may be affected by a number of factors including seasonal changes in larval or adult nutrition. The effect of season on the reproductive potential of Monochamus galloprovincialis (Olivier) females reared in Pinus sylvestris L. (Scots pine) logs was investigated by constructing fertility tables for each log that differed only in the season they were cut Population parameters were compared among three seasonal cohorts. The intrinsic rate of increase and most of the associated population parameters of beetles that emerged from logs cut during spring were higher than for beetles emerged from summer and autumn logs. Slight differences were found between summer and autumn cohorts. We suggest that seasonal differences in the nutritional quality of logs caused differences in M. galloprovincialis survival and reproductive potential.
