Following the detection of the quarantine bacterium (Wells et al.) in the Apulia region (southern Italy) and the identification of spittlebugs as the main vector species that contributes to its epidemic spread, monitoring activities have been intensified in an attempt to implement vector control strategies. To date, sweep nets have been the most widely used sampling method to monitor adult spittlebug populations. Field experiments were carried out, during 2018 and 2019, to evaluate the effectiveness of sticky traps in capturing spittlebugs in different woody crops. The attractiveness of different traps was compared: four colored sticky traps (white, red, blue, and yellow), with the yellow sticky traps having three different background patterns (plain yellow, yellow with a black circle pattern, and yellow with a black line pattern). In addition, the efficiency of the yellow sticky traps was evaluated by placing the traps on the ground or hanging them from the canopies in orchards with different spittlebug population densities. Trap catches of (Linnaeus) and (Fallén) (Hemiptera: Aphrophoridae) were compared with those collected using sweep nets. The two spittlebug species showed a similar response to the colored traps and were mainly attracted to the yellow sticky traps. Captures throughout the adult season indicated that an accurate estimation of the presence and abundance of spittlebugs can be obtained by integrating the two sampling methods. Moreover, sweep nets appeared to be more efficient in collecting adults soon after their emergence, while the use of sticky traps was more efficient in the rest of the adult season when the use of traps can significantly expedite vector monitoring programs.
在普利亚地区（意大利南部）检测到检疫细菌（韦尔斯等人），并确定沫蝉为导致其疫情传播的主要媒介物种后，监测活动得到加强，以试图实施媒介控制策略。迄今为止，扫网一直是监测成年沫蝉种群最广泛使用的采样方法。在2018年和2019年期间进行了田间试验，以评估粘性诱捕器在不同木本作物中捕获沫蝉的有效性。比较了不同诱捕器的吸引力：四种颜色的粘性诱捕器（白色、红色、蓝色和黄色），其中黄色粘性诱捕器有三种不同的背景图案（纯黄色、带黑色圆圈图案的黄色和带黑色线条图案的黄色）。此外，通过将黄色粘性诱捕器放置在地面上或挂在不同沫蝉种群密度果园的树冠上来评估其效率。将（林奈）和（法伦）（半翅目：沫蝉科）的诱捕捕获量与使用扫网收集的捕获量进行了比较。这两种沫蝉物种对有色诱捕器表现出相似的反应，主要被黄色粘性诱捕器吸引。整个成虫季节的捕获情况表明，通过整合这两种采样方法可以准确估计沫蝉的存在和数量。此外，扫网在成虫刚出现后收集成虫似乎更有效，而在成虫季节的其余时间使用粘性诱捕器更有效，此时使用诱捕器可以显著加快媒介监测计划。
