The success of integrated pest management programs depends on the use of feasible and efficient sampling plans. Considering that the citrus blackfly, Aleurocanthus woglumi Ashby (Hemiptera: Aleyrodidae), is an important citrus pest, the aim of this research was to develop a conventional sampling plan to assess adult populations of this insect in orange orchards. For this, we defined the sampling unit, number of samples, time and the cost of sampling. The third most apical leaf of the branch was the ideal unit to assess citrus blackfly adult densities and the sampling plan consisted of 58 samples. On average, the plan required 55.26 min to complete and costs US$ 1.78. The sampling plan developed here is an accurate, viable and low-cost tool that can be used in integrated pest managemant programs in orange orchards. Our methods can also be applied to study ecological and geographic parameters of this pest.

综合虫害管理计划的成功取决于使用可行和有效的抽样计划。考虑到柑橘黑蝇，Aleurocanthus woglumiAshby (Hemiptera: Aleyrodidae) 是一种重要的柑橘害虫，本研究的目的是制定常规的抽样计划，以评估橙园中这种昆虫的成虫种群。为此，我们定义了抽样单位、样本数量、时间和抽样成本。第三个最顶端的枝叶是评估柑橘黑蝇成虫密度的理想单位，采样计划由 58 个样本组成。平均而言，该计划需要 55.26 分钟才能完成，费用为 1.78 美元。此处制定的采样计划是一种准确、可行且低成本的工具，可用于橙园的综合虫害管理计划。我们的方法也可用于研究这种害虫的生态和地理参数。
