| Abstract:
Various observations on the biology of Pseudaulacaspis pentagona (Targioni Tozzetti) (Homoptera: Diaspididae) were carried out in field and laboratory conditions in order to improve defence strategies and develop a forecasting model. To assess the developmental rate of each stadium, constant temperature readings were taken and the moulting process was examined in slide-mounted specimens by analysing the detachment of the new cuticle from the old one or the renewal of stylets. The reproductive potential was investigated by recording the duration in days of egg-laying, and counting the number of eggs produced daily. The aim was to develop a population forecasting model. | |
