摘要

柑橘麻风是由柑橘麻风螨传播的一种主要病毒性疾病,对巴西柑橘种植业造成重大经济损失。本研究在两个柑桔栽培系统中制定了短叶蜂的序贯取样计划。在巴西parar首都 o poo的一个橙子果园(‘Pêra里约热内卢’品种)中选择了两个地块:一个是单一栽培,另一个是柚木间作。2015年9月至2016年8月,每个样地每月采样112株地理参考植物。使用10倍口袋透镜对植物内外6个果实、树枝和叶子进行螨计数。包括方差均值比、森西塔指数、格林系数和泰勒幂律在内的聚集指数揭示了所有变量的聚集分布。负二项分布的k参数证实了聚集性,该模型对两种系统都提供了最佳拟合。顺序采样计划确定了决策的最大期望采样单位是每个工厂21个螨,两个系统中每六个分支28个螨。这些阈值是根据观察到的分布模式建立的,旨在提高监测效率。虽然这些值可能看起来很低,但它们表明了应采取控制措施以防止经济损失的虫害程度。这些发现有助于改进柑橘果园短肢蝇的监测策略,支持更有效的害虫管理。

Sequential sampling of the citrus leprosis mite in different cultivation systems in the Eastern Amazon.

Citrus leprosis is a major viral disease transmitted by the citrus leprosis mite (Brevipalpus spp.), causing significant economic losses in Brazilian citrus farming. This study developed a sequential sampling plan for Brevipalpus spp. in two citrus cultivation systems. Two plots in an orange orchard ('Pêra Rio' variety) in Capitão Poço, Pará, Brazil, were selected: one under monoculture and the other intercropped with teak. Monthly sampling from September 2015 to August 2016 involved 112 georeferenced plants per plot. Mite counts were performed on six fruits, branches, and leaves from both inner and outer plant parts using a 10 × pocket lens. Aggregation indices, including variance-to-mean ratio, Morisita's index, Green's coefficient, and Taylor's power law, revealed an aggregated distribution for all variables. The k parameter of the negative binomial distribution confirmed aggregation, and this model provided the best fit for both systems. The sequential sampling plan determined that the maximum expected sampling units for decision-making is 21 mites per plant and 28 mites per six branches in both systems. These thresholds were established based on the observed distribution pattern and aim to enhance monitoring efficiency. Although these values may seem low, they indicate the infestation level at which control measures should be implemented to prevent economic losses. These findings contribute to improved monitoring strategies for Brevipalpus spp. in citrus orchards, supporting more effective pest management.

期刊介绍: Experimental and Applied Acarology publishes peer-reviewed original papers describing advances in basic and applied research on mites and ticks. Coverage encompasses all Acari, including those of environmental, agricultural, medical and veterinary importance, and all the ways in which they interact with other organisms (plants, arthropods and other animals). The subject matter draws upon a wide variety of disciplines, including evolutionary biology, ecology, epidemiology, physiology, biochemistry, toxicology, immunology, genetics, molecular biology and pest management sciences.
