Temperature effects on development of Liriomyza trifolii
In Germany, temperature effects on the development of Liriomyza trifolii (EPPO A2 pest) were studied.
Laboratory experiments showed that the temperature sums and threshold temperatures for development of the different stages were:
egg: - 40,8 day-degrees C and 14 C
larva: - 31,5 day-degrees C and 13,8ø C
pupa: - 107,4 day-degrees C and 13,6ø C
total: - 172,5 day-degrees C and 14,7ø C
