Ecology of Phoracantha semipunctata

Observations in the province of Huelva, Spain, on the ecology of Phoracantha semipunctata (EPPO A2 pest) showed that the mean temperature should not be lower than 15ø C for the oviposition of the eucalyptus borer. The earliest emergences were observed 62 days after oviposition, but emergences after 15 and 16 months were also observed. Small parts of the populations were able to give rise to two generations per year, but most had only one. The observations on the ecology of the pest were included in a model for prediction of emergence in P. semipunctata.
