Abstract

Sampling plans are essential components to establish decision-making systems for integrated pest management (IPM) programs. Thus, this study was aimed to develop a conventional sampling plan of Tetranychus mexicanus (McGregor) (Tetranychidae) on the yellow passion fruit Passiflora edulis. The work was conducted in nine passion fruit fields with plants at the reproductive stage. Our results indicated that the sample, ideal area, and the technique for the evaluation of the mites in passion fruit were the second and third most apical leaves on the branches, the leaf blade on the abaxial surface near the petiole, and the directly counting the mites using a hand lens with 10× magnification, respectively. The density of T. mexicanus was adjusted to a negative binomial frequency distribution, and they present a common aggregation parameter (Kcommon = 0.5176), which made it possible to generate a sampling plan. The sampling plan consisted of 52 samples per field that took 39 minutes, and the cost of US $6.73 per sampling, respectively. Thus, the sampling plan developed in this study can be used by farmers in management programs for T. mexicanus in passion fruit crops by facilitating the accurate, representative and feasible sampling of this pest at the plant.

百香果藤上墨西哥叶螨的取样方案

摘要

抽样计划是为综合虫害管理 (IPM) 计划建立决策系统的重要组成部分。因此,本研究旨在制定对黄色百香果Passiflora edulis 进行墨西哥叶螨(McGregor) (叶螨科)的常规取样计划。这项工作在九个百香果田中进行,植物处于繁殖期。我们的结果表明,西番莲果中螨类的样品、理想面积和评价技术是树枝上第二和第三最顶端的叶子,靠近叶柄的背面叶片,直接计数分别使用放大倍数为 10 倍的手持镜头观察螨虫。T. mexicanus的密度被调整为负二项式频率分布,并且它们呈现一个共同的聚合参数(K common = 0.5176),这使得生成采样计划成为可能。抽样计划包括每个油田 52 个样本,耗时 39 分钟,每个样本的成本分别为 6.73 美元。因此,农民可以将本研究中制定的抽样计划用于西番莲果作物中的墨西哥烟草管理计划,方法是在植物中对这种害虫进行准确、有代表性和可行的抽样。
