摘要

背景：chetanaphothrips orchidii是一种热带入侵蓟马，于2016年在西班牙柑橘中发现，它可以破坏高达70%的水果。化蛹地点和羽化率是蓟马管理的关键生物学性状，而这些性状对兰氏蓟马是未知的。本研究确定了柑桔褐皮蛾的化蛹地点和化蛹时间，并评价了土壤湿度对其羽化的影响。结果：2年的田间研究表明，5月至12月，柑桔商品园土壤中有绒螟蛹化。与柑橘中其他有害蓟马相比，兰毛蓟马的出苗率很低。利用D/E诱捕法发现，夏季蓟马主要出现在滴灌灌区附近的湿润地区，其出现与土壤含水量密切相关。室内实验证实，在RH低于70%时，革纹睾虫不出虫，在97% RH时，革纹睾虫出虫高峰。结论：我们的研究结果对柑橘的可持续管理具有重要意义，因为地中海柑橘在夏季土壤湿度非常低，除了滴灌排放点附近的地区。因此，这些地区和其他潜在的高湿度地区应被视为夏季控制柑橘害虫的关键目标，以降低成本和劳动力。©2024化学工业学会。

Moisture-dependent pupation of the invasive thrips Chaetanaphothrips orchidii: implications for its management

BACKGROUND

Chaetanaphothrips orchidii is an invasive thrips of tropical origin that was detected in 2016 in Spanish citrus, where it can damage up to 70% of the fruit. Pupation site and emergence rates are key biological traits for thrips management that are unknown for C. orchidii. Here, we determined the pupation site and period of C. orchidii in citrus and evaluated the effect of soil moisture on adult emergence.

RESULTS

A two-year field study showed that C. orchidii pupated in the soil from May to December in commercial citrus orchards. Chaetanaphothrips orchidii emergence was very low compared to other harmful thrips species in citrus. Using D/E traps, we demonstrated that the thrips emerged mainly from wet areas near drip irrigation emitters during the summer, and its emergence was strongly related to the soil water content. A laboratory experiment confirmed that C. orchidii did not emerge at RH below 70%, and its emergence peaked at 97% RH.

CONCLUSIONS

Our results have important implications for the sustainable management of C. orchidii because soil moisture is very low in Mediterranean citrus during summer, except in areas near drip irrigation emitters. Therefore, these and other potential high-humidity areas should be considered crucial targets to manage this pest in citrus during summer, reducing cost and labor. © 2024 Society of Chemical Industry.
