Embryonic development of orchard leafrollers and the forecasting of egg hatch
Entomologia Experimentalis et Applicata 99 (3), 313-317
Abstract: The development time of eggs of three of the most noxious leafrollers found in Northeuropean orchards, Spilonota ocellana (Denis and Schiffermüller), Archips podana (Scopoli), and Pandemis heparana (Denis and Schiffermüller) (Lepidoptera: Tortricidae) was recorded in the laboratory at five constant temperatures between 14 and 25 °C. In this range, developmental rates of the three species did not differ significantly. While the flight periods of these species overlap largely, a single algorithm could be used to devise optimal spraying time(s) for the three species.
