| A study was undertaken from 1993 to 1994 to determine the effects of intercropping (with Glycine max L Merr., Lupinus sp., Trifolium pratense L.-Lolium multiflorum Lam., or Secale cereale L.) and mechanical weeding (with a rigid tines cultivator, Danish tines cultivator or ridge cultivator) on the population dynamics of insect pests (Diabrotica longicornis Say, Lygus lineolaris Palisot de Beauvois, Ostrinia nubilalis Hubner, and Pseudaletia unipuncta Haworth) on corn (Zea mays L.) in L'Assomption and Sainte-Anne-de-Bellevue, Quebec, Canada.;In 1994, intercropping with T. pratense-L. multiflorum (Sainte-Anne-de-Bellevue) or weeding with the Danish tines cultivator (L'Assomption) increased L. lineolaris populations.;In 1994, intercropping with S. cereale (L'Assomption) ot T. pratense-L. multiflorum (Sainte-Anne-de-Bellevue) increased O. nubilalis populations.;D. longicornis or P. unipuncta populations did not increase. |
