Abstract
This work was carried out at the Institute of Sustainable Horticulture of the Polytechnic University of Kwantlen, British Columbia, Canada, with the objective of evaluating the effect of entomopathogenic nematodes in the management of P. xylostella. The strains, Steinernema feltiae L. (ENTONEM) and H. bacteriophora L. (LARVANEM) of the company Koppert B. V and a strain produced by the traditional method on insect larvae of the company Coopers of H. bacteriophora were used. The concentrations used were 45, 100, 150 and 200 iji/larva/mL. Cabbage seeds were obtained from the West Coast Seeds company. Among the main results it was obtained that the best percentage of mortality for the S. feltiae strain was at 96 hours with the concentrations of 200 and 150 jii/larva and for the strains of Heterorhabditis it was reached at 72 hours with 200 and 150 iji/larva.
