      abstract = {The use of chemical insecticides in the control of insect  pests has left in its wake resistance of some pests to some  of the conventional insecticides. Alternative methods of  managing pests such as cultural control have to be employed  to reduce pest infestation of crops. Onion was used in an  intercrop as a non host crop to manage the pests of  cabbage. The experiment was conducted in a Randomized  Complete Block Design with four treatments; sole cabbage  (T1), 2 rows of cabbage to 1 row of onion (T2), 3 rows of  cabbage to 1 row of onion (T3) and 4 rows of cabbage to 1  row of onion (T4), each of which was replicated three  times. Data were collected on pests’ numbers, plant height,  damaged leaves at harvest, canopy spread, number of damaged  heads and fresh weight. Significantly fewer Bemisia tabaci,  Hellula undalis and Brevicoryne brassicae infested the  intercropped plants than the sole crop. However,  intercropping cabbage with onion did not significantly  reduce Plutella xylostella population on cabbage. Number of  damaged heads, fresh weight and damaged leaves were  significantly different (P< 0.05).},
