摘要

Detection of pestiferous Bactrocera fruit flies relies largely on traps baited with male-specific attractants. Surveillance programs in Florida and California use liquid methyl eugenol (ME, attractive to males of B. dorsalis (Hendel)) and liquid cue-lure (CL, attractive to males of B. cucurbitae (Coquillett)) mixed with the toxicant naled to bait traps. However, the application of the liquids requires considerable time and may subject personnel to health risks from inadvertent exposure to the lure and the insecticide. Recent studies have shown that solid dispensers containing a toxicant perform as well or better than liquid lures, but the combination of lure and toxicant in the same solid dispenser faces registration problems. Fewer studies have assessed the efficacy of solid, and separate, lures and toxicants, but existing data are promising. Here, we present the results of two independent studies that further assess the effectiveness of solid ME and CL lures and their associated, but separate, insecticidal strips. The first study, conducted exclusively in Hawaii over a 12 week period, found that captures of B. dorsalis or B. cucurbitae males were similar between traps baited with the standard liquid formulation and traps baited with solid lure dispensers and either 1 or 2 insecticidal strips. In the second study, solid lure dispensers and associated insecticide strips were weathered for 6 or 12 weeks under summer conditions in Arizona and Florida, where high temperatures were presumed to resultin high volatility and thus provide a rigorous test of field longevity. Aged materials were shipped to Hawaii for testing against fresh (non-weathered) lures and insecticidal strips in wild populations. The results were fairly consistent between Arizona- and Florida-weathered devices and indicated that (i) solid ME dispensers were effective for 6 weeks but lost significant attractancy at 12 weeks and (ii) CL solid lures and the insecticidal strips were effective for at least 12 weeks. Collectively, these findings provide additional evidence that surveillance programs could switch to solid lures and toxicants and maintain a high level of detection sensitivity.

Cucurbitae（Coquillett）的雄性有吸引力的混合毒品诱饵陷阱。然而，液体的应用需要相当长的时间，并且可以从无意地暴露于诱饵和杀虫剂的健康风险。最近的研究表明，含有毒物的固体分配器也比液体诱饵更好，但是在相同的固体分配器中的诱饵和毒物的组合面向登记问题。更少的研究评估了固体，分离，诱饵和毒物的疗效，但现有数据很有前景。在这里，我们介绍了两个独立研究的结果，进一步评估了固体ME和Cl诱导的有效性及其相关的，但分离的杀虫条。第一项研究在夏威夷在夏威夷进行了12周，发现B. dorsalis或B.葫芦菌雄性的捕获与标准液体配方和捕获剂的捕获剂和1或2条杀虫条带来相似。在第二项研究中，在亚利桑那州和佛罗里达州的夏季条件下，在夏季条件下，在夏季条件下风化固体吸管分配器和相关的杀虫剂条带来高温，从而产生高挥发性，从而提供对现场寿命的严格测试。老化材料被运送到夏威夷，用于测试野生种群中的新鲜（非风化）诱饵和杀虫条。结果在亚利桑那州和佛罗里达风化的装置之间相当一致，并表明（i）固体ME分配器为6周，但在12周和（ii）Cl固体诱饵中丧失显着的抑制，并且杀虫条至少有效12周。总的来说，这些调查结果提供了额外的证据，即监测程序可以切换到固体诱饵和毒物，并保持高水平的检测灵敏度。
