Abstract

Ceratitis capitata is the most serious agricultural pest in Argentinean fruit-growing regions. The use of baited traps for Medfly control is an expanding and increasingly successful integrated management strategy. The high cost of traps and attractants is one of the main limitations for use on either a massive scale or a small-scale control. This study aimed to evaluate the advantages or disadvantages of using natural fruit juice-based lures for Medfly adult monitoring at the orchard level in an irrigated valley. Medfly capture with a standard protein attractant was compared with peach, apple, sweet orange, fig, and grape juices. All attractants were evaluated in 1.5-liter disposable plastic bottles that served as traps. The most relevant finding was the interaction between attractant effectiveness and season. While the standard yeast was the most effective attractant during summer, the highest Medfly caught values recorded during both spring and autumn were achieved with traps baited with orange juice. The use of fruit juices as attractants and disposable bottles as traps can decrease the impact on non-target insects and reduce management costs.

摘要

头状实蝇是阿根廷水果种植区最严重的农业害虫。使用诱饵来控制地中海果蝇是一种不断扩大且日益成功的综合管理策略。诱捕器和引诱剂的高成本是大规模或小规模控制使用的主要限制之一。本研究旨在评估使用天然果汁诱饵在灌溉山谷果园监测地中海果蝇成虫的优点或缺点。将使用标准蛋白质引诱剂捕获的地中海果蝇与桃汁、苹果汁、甜橙汁、无花果汁和葡萄汁进行了比较。所有引诱剂均在用作诱捕器的 1.5 升一次性塑料瓶中进行评估。最相关的发现是引诱剂有效性和季节之间的相互作用。虽然标准酵母是夏季最有效的引诱剂，但春季和秋季记录的最高地中海果蝇捕获值是通过用橙汁作为诱饵的诱捕器实现的。使用果汁作为引诱剂和一次性瓶子作为诱捕器可以减少对非目标昆虫的影响并降低管理成本。
