Abstract

True fruit fly species (Diptera: Tephritidae) threaten the production and international trade of many fruit and vegetable crops. Many fruit fly-free regions operate trapping programs for the detection of these invasive pests, and food baits are an important component of detection trapping. A torula yeast-borax (TYB) solution has been widely used as a food bait, but it has a relatively short field longevity and is generally replaced every 1–2 weeks. Dry synthetic food-based attractants, consisting of ammonium acetate, putrescine, and trimethylamine, have been developed and appear to be effective for several months. Initially, the three components were presented in individual sachets within a trap, but to ease handling ‘all-in-one’ dispensers have been developed that contain all three components. While a logistical improvement, there are few data that compare captures between the standard TYB solution and these combination dispensers. This study presents the results of field experiments assessing the relative effectiveness of three ‘all-in-one’ dispensers of synthetic food-based attractants (i.e., Scentry food cones, Suterra Unipaks, and Susbin Difusors) in trapping three major pest species of tephritid fruit flies in Hawaii. The data presented here indicate that, with respect to C. capitata, the Difusor lures performed as well as TYB, while the Unipaks and food cones were significantly less attractive than TYB. With respect to B. dorsalis and Z. cucurbitae, none of the synthetic baits tested was as effective as TYB. Thus, among the baits studied here, TYB was most effective in attracting all three of the target species.

用于检测入侵果蝇(双翅目:栉孔蝇科)的合成食物引诱剂的实地研究
真果蝇(双翅目:Tephritidae)威胁着许多水果和蔬菜作物的生产和国际贸易。许多无果蝇地区都实施了诱捕计划来检测这些入侵害虫,而食物诱饵是检测诱捕的重要组成部分。酵母硼砂(TYB)溶液已被广泛用作食物诱饵,但其田间寿命相对较短,一般每 1-2 周更换一次。由醋酸铵、腐胺和三甲胺组成的干性合成食物型引诱剂已经开发出来,似乎可以在几个月内有效。最初,这三种成分分别装在诱捕器中的小袋里,但为了便于操作,已经开发出了包含所有三种成分的 "一体化 "分配器。虽然在物流方面有所改进,但很少有数据可以比较标准 TYB 溶液和这些组合分配器的捕获量。本研究介绍了实地实验的结果,评估了三种 "一体式 "合成食物引诱剂投放器(即 Scentry 食物锥、Suterra Unipaks 和 Susbin Difusors)在夏威夷诱捕三种主要害虫潮气果蝇的相对效果。本文提供的数据表明,对于 C. capitata,Difusor 诱饵的诱捕效果与 TYB 相当,而 Unipaks 和食用锥的诱捕效果明显不如 TYB。对于 B. dorsalis 和 Z. cucurbitae,所测试的合成诱饵都不如 TYB 有效。因此,在本文研究的诱饵中,TYB 在吸引所有三种目标物种方面都最为有效。
