Abstract: The development of an efficient control of insect pests of cabbage requires the knowledge of these pests and their auxiliaries. To do this, an inventory of insects associated with cabbage cultivation was conducted from July to September 2016 and from February to April 2017 on three market gardening perimeters in Korhogo. The identification revealed the presence of 48 species grouped into 32 families and 10 orders. Twenty-five species have been identified as cabbage pests. Lipaphis erisimy (19.21%) and Plutella xylostella (11.20%) were classified as very abundant. Auxiliary fauna was dominated by six parasitoid Hymenoptera. Cotesia vestalis was the most abundant species. The distribution of species by phenological stage showed that there were 41 species present during the vegetative stage and during apples and 36 species at maturation. C. vestalis, L. erisimy, P. xylostella and M. persicae accounted for more than 50% of the insect population at each phenological stage.
