s are listed in alphabetical order by the last name of the senior author. Parasitoids of Myzus persicae and Aulacorthum solani on pepper crops in British Columbia Susanna Acheampong, David R. Gillespie and Don Quiring Pacific agri-Food Research Centre (Agassiz); 6947 #7 Highway; P. O.

Volatile organic compounds (VOCs) from uninfested and infested broccoli plant samples with green peach aphid Myzus persicae were investigated by headspace solid microextraction (HS-SPME) combined gas chromatography mass spectrometry (GC-MS). Overall, 25 identified in plants. The HS-SPME GC-MS analysis of the volatiles described differences between samples. Based on peak area analysis, VOCs sign...
There are many different practices that contribute to conservation biological control, but little is known about their complementarity. We tested the effects of providing food and alternative hosts parasitoids by intercropping a plum orchard with companion plants. Oats vetch were intercropped into either as single-species (oats or vetch) two-species combined) intercrops within an inter-row. The...

Cotton produces insecticidal terpenoids that are induced by tissue-feeding herbivores. Damage by Heliothis virescens caterpillars increases the terpenoid content, which reduces the abundance of aphids. This effect is not evident in Bt-transgenic cotton, which is resistant to H. virescens. We determined whether induction of terpenoids by caterpillars influences the host quality of Aphis gossypii...
Wasps of the braconid subfamily Aphidiinae are solitary endoparasitoids of aphids. Several aspects of their biology have been the focus of intuitive evolutionary hypotheses which could be tested with a robust phylogeny. Phylogenetic hypotheses have been proposed previously for aphidiines based on morphology, embryology, and DNA sequences. However, many of them are based on a limited number of c...
