Oil palm is an important cash crop in Côte d'Ivoire. This plant harbors many insects, including pollinators that actively participate in its production. However, the populations of these insects are often destroyed by man through the chemical treatments. This work aimed to conduct a comparative study of the effect of three chemical insecticides on oil palm pollinating insects. The insecticides Evisect-S 50, Sivanto Energy 85 EC and Proteus 170 O-TEQ, were mixed respectively with 25 g/10 L of water and 25 ml/10 L of water to make the slurries used for the different treatments. The results revealed the presence of pollinating insects in all treatments. Therefore, all of the chemicals tested were harmful to pollinating insects for the first three days after application. However, Evisect-S 50 caused more deaths during these three days. From day 7 to day 14 the effect of these insecticides was lessened. Therefore, these chemicals do not have a significant long-term effect on oil palm pollinating insects. Nevertheless, it would be necessary to assess the effect of other chemicals as well as the impact of certain natural enemies on pollinating insects.
