Onion (Allium cepa L.) is a widely consumed food product in Ivory Coast. Unfortunately, low local production is noted, forcing the State to remain dependent on the countries of the sub-region and Europe. A significant increase in local onion production is, therefore, necessary. This necessarily involves sustainable management of the entomological constraints of onion cultivation which remains little known in Ivory Coast to date. This study aims at evaluating thrips (Thysanoptera: Thripidae) incidences, the main insects harmful to onion cultivation in the northern Ivory Coast. These incidences were evaluated on five (5) onion varieties (SAFARI, BATI, CARA, VIOLET DE GALMI, and ROUGE KARIBOU) on a weekly basis from four (4) weeks after transplanting until bulbs maturity. A factorial ANOVA was used to test the variety and sampling period effects. It showed that the incidence of thrips is low at the start of cultivation, and increases significantly with vegetative growth. The incidences of thrips vary between onion varieties. SAFARI was the most attacked variety by thrips with incidences that can exceed 40%. SAFARI was followed by BATI, CARA, and VIOLET DE GALMI which presented intermediate incidence. ROUGE KARIBOU variety recorded incidences of less than 20% throughout the crop cycle. This variety (ROUGE KARIBOU) could be recommended to market gardeners because it is less attractive to thrips.
