The red palm weevil, Rhynchophorus ferrugineus Olivier (Coleoptera:
Curculionidae), is an economically important pest of palms worldwide. To better
understand the phenology of R. ferrugineus populations in the Mediterranean basin,
the objective of the present work has been to estimate the effect of temperatures
within the range 10–25°C on the reproductive parameters of R. ferrugineus and to
determine its lower temperature thresholds for oviposition and egg hatching. Our
results confirm that oviposition in R. ferrugineus is strongly affected by temperature.
Lower thresholds for oviposition and egg hatching (15.45° and 13.95°C, respectively)
are below the mean monthly temperatures registered in winter in most of the
northern shore of the Mediterranean basin. Under these circumstances, new palm
infestations would be difficult during most of the winter. These results should be
taken into account when planning some palm management practices, such as
pruning or pesticide treatments, in areas under a Mediterranean climate. [-]
