Effects of host plant and temperature on Aphidius colemani (Hymenoptera: Braconidae) intrinsic rate of population increase

Effects of host plant and temperature on Aphidius colemani (Hymenoptera: Braconidae) intrinsic rate of population increase content piece image
The aim of this paper was to investigate the aphid-mediated effects of plant (Nicotiana tabacum or Vicia faba ) on A. colemani life-history characteristics. The obtained results corroborated our hypothesis that the host plant is important factor in an aphid-parasitoid relationship. Plant toxins are probably the cause of lower rate of population increase in A. colemani developed on tobacco-reared aphids.
