Extract
Pieris rapae (L.) (Lepidoptera: Pieridae) is endemic in the Canary Islands, presumably since Roman times. Average temperatures at sea level on Tenerife and La Gomera range from 17°C at midwinter to 25°C in summer. If the argument of Gilbert and Raworth (1996) is correct, we might expect the development threshold of P. rapae in the Canaries to be 17°C, much higher than the 10°C observed elsewhere: Cambridge, U.K.; Cordoba, Spain; Pompei, Italy; Montpellier, France; Vancouver, Canada; and Canberra, Australia (Gilbert 1988).
