A biological evaluation of five European cultures ofAnaphes flavipes [Hymenoptera: mymaridae], an egg parasite ofOulema melanopus [Coleoptera: chrysomelidae]

Comparative biological data on five European cultures ofAnaphes flavipes Hymenoptera: Mymaridae], an egg parasite ofOulema melanopus Coleoptera: Chrysomelidae], indicated differences in developmental rates as those individuals representing cultures from the southernmost latitudes developed the slowest at 21°C, while those from the northernmost latitudes developed the fastest at this temperature. At 15.6°C, however, the parasites from the southern latitudes developed faster than those from the northern latitudes. Variations in other biological attributes, including longevity and fecundity, were not statistically significant.
