Abstract

The screening of potential chemicals for control of Bemisia tabaci check for this species in other resources on poinsettia ( Euphorbia pulcherrima check for this species in other resources c.v. Lilo Pink) plants using a leaf dipping technique was investigated. All relevant B. tabaci lifestages (eggs, larvae and adults) were investigated. In leaf dipping tests, Certis spraying oil was the only compound to show potential to be used as a control agent against B. tabaci eggs, with 81% obtained mortality. Oberon resulted in no mortality of B. tabaci eggs in the reported experiments. Leaf dipping against second instar and adult B. tabaci proved more effective for all chemical products. Dipping techniques using Majestik, Certis spraying oil and Agri-50 E all resulted in high second instar larval mortality (93, 87 and 85.5 %, respectively). Certis spraying oil again resulted in a high efficacy against adult B. tabaci with 100 % mortality obtained. The potential of the various chemicals to be incorporated into integrated pest management strategies for the control of B. tabaci is discussed.
