Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a major pest of many agricultural and ornamental crops responsible for damages that cause significant economic losses. Insecticides are commonly used in the field to control populations of B. tabaci leading to rapid development of resistance making the use of insecticides ineffective. Therefore, other strategies must be developed for the management this pest. Herein, we compare the toxicity of Lannea velutina, Combretum micrantum, Combretum paniculatum, Lannea kerstingii seed oils and three fractions (acetone, chloroform and hexane of Lannea kerstingii) to three conventional insecticides (acetamiprid, deltamethrin and chlorpyriphos-ethyl used as a positive control) using the leaf dip method. Two biotypes of B. tabaci (MED-Q1 and MED-Q3) belonging to Mediterranean species and collected in Burkina Faso were used. We have shown that the two biotypes have different levels of resistance compare to the three insecticides, with MED-Q3 being most susceptible. On the other hand, both biotypes are most susceptible to plant extracts compare to the insecticides, with the exception of chlorpyrifos-ethyl. Our results indicate that seeds oils can be an alternative to chemical control.

烟粉虱（Bemisia tabaci（Gennadius）（半翅目：Aleyrodidae））是许多农业和观赏性作物的主要害虫，造成的损害造成重大的经济损失。杀虫剂在该领域中通常用于控制烟粉虱的种群，从而导致耐药性的快速发展，从而使杀虫剂的使用无效。因此，必须制定其他策略来控制这种有害生物。这里，我们比较的毒性厚皮树属绒毛，风车子micrantum，风车子紫草，厚皮树属kerstingii种子油和三个部分（丙酮，氯仿和己烷的厚皮树属kerstingii）使用叶浸法对三种常规杀虫剂（乙草胺，溴氰菊酯和毒死pho-乙基用作阳性对照）。使用了两种生物型的地中海烟粉虱（MED-Q1和MED-Q3），属于地中海物种并在布基纳法索采集。我们已经表明，与三种杀虫剂相比，两种生物型具有不同的抗药性，其中MED-Q3最易感。另一方面，除毒死rif乙基外，与杀虫剂相比，两种生物型对植物提取物最敏感。我们的结果表明，种子油可以替代化学防治方法。
