Temperature effect on the predation rate of Anthocoris nemorum (Het.: Anthocoridae) on cabbage aphids (Hom.: Aphididae)

The temperature-dependent predation by Anthocoris nemorum L. (Het.: Anthocoridae) on second instar Brevicoryne brassicae L. (Hom.: Aphididae) at constant temperatures of 12, 15 and 20 degrees C increased linearly with temperature with a mean (+/- SE) consumption of 6.9 (+/- 0.8), 9.28 (+/- 1) and 15.9 (+/- 0.8) respectively. The estimated lower temperature threshold for predation (T-0) was 6.4 degrees C.
