These factors have contributed to the implementation of new ecological-friendly approaches to manage pests in crops [1, 2]. Spring onion was intercropped in all treatments. Alternative methods of managing pests such as cultural control have to be employed to reduce pest infestation of crops. Parameters studied included insectpest numbers and their natural enemies, number of days to 50% flowering, plants height at flowering(cm), number of fruits per plant, fruit damage, and mean weight of fruits (g). Center (ATARC) during 2013 September to December. Feeding results in leaf curling, stunting, drying of leaf tissues along with the development of sooty mold fungi, restricting photosynthesis, consequently [11,12]. Two field experiments were conducted on-station at the CSIR-Crops Research Institute, Kwadaso, Kumasi, and on-farm at Eatwell farm at Agona-Mampong all in the Ashanti region of Ghana from December 2009 to March 2010 and September to December 2010, respectively. Thrips are very small, slender insects that can be easily seen with a hand lens. This study was conducted to evaluate the effectiveness of intercropping cabbage with non-host crops in reducing the effect of the diamondback moth pest on cabbage. There was a positive correlation between temperature and LAI in control treatment (r=0.33, p<0.05), onion intercrop (r= 0.23, p<0.05) and marigold intercrop (r= 0.25, p<0.05). Although, spring onions are highly perishable, so ensure to buy in small quantities. In a previous study, intercropping of onion with cabbage was done to manage diamondback moth Plutella xylostella (L) and other pests of cabbage [10].
