Cockroaches are the pest of major concern for the disinfestation programs of the sanitary system in Italy. Hygienic-sanitary interest is linked to the role of mechanical vectors of pathogens and to their allergological potential. Sticky traps are the best tool to monitor the presence of these insects and several types of them are available on the market. In most of the cases the traps are not indicated for a given species, but, instead, generically for cockroaches. Domestic cockroaches differ in morphology, size and habits. Consequently, the effectiveness of the trap can change in relation to the target species.
In this study three of the most employed traps in Italy were compared: the INDIA trap with and without its attractant tablet (hereafter mentioned as INDIA-A and INDIA-E, respectively), the ZAPI Simply trap and the CATCHMASTER Spider & Insect Glue trap. We chose the four most common species of cockroach (Blattodea) in Italy, Blatta orientalis (L.), Periplaneta americana (L.) (Blattidae), Blattella germanica (L.) and Supella longipalpa (F.) (Blattellidae). Each species of cockroach was tested separately inside arenas containing one of the traps. Each test (one species with one kind of trap) was replicated five times.
The INDIA-A trap collected more cockroaches of every species, followed by the INDIA-E. The ZAPI trap caught less specimens of each species in respect to the INDIA traps, with the only exception of B. orientalis, for which the ZAPI trap caught more than the INDIA-E. The CATCHMASTER trap performed significantly less for all the species. B. orientalis was the species most abundantly caught by all traps, followed by B. germanica, S. longipalpa and P. americana. No significant difference was observed in the catch according to the developmental stage. In general, there was no particular predisposition of any trap to catch a particular species.
It is not possible to indicate a model of trap for each species of cockroach, but it is clear that different traps have different performances in terms of attractiveness and capture. Therefore, the choice of the trap affects the results of the monitoring, and as consequence, the evaluation of the infesting population of the pest.
蟑螂是意大利卫生系统除虫计划中主要关注的害虫。卫生和健康利益与病原体的机械载体以及它们的过敏潜力有关。粘虫板是监测这些昆虫存在的最佳工具，市场上有几种类型。在大多数情况下，陷阱并不针对特定物种，而是通常针对蟑螂。家庭蟑螂在形态、大小和习性上有所不同。因此，陷阱的有效性可能会因目标物种而异。
本研究比较了意大利最常用的三种陷阱：带有和不带有引诱剂片剂的 INDIA 陷阱（以下分别简称为 INDIA-A 和 INDIA-E）、ZAPI Simply 陷阱和 CATCHMASTER 蜘蛛和昆虫胶陷阱。我们选择了意大利最常见的四种蟑螂（蜚蠊目），东方蜚蠊（L.）、美洲大蠊（L.）（蜚蠊科）、德国小蠊（L.）和大蠊（F.）（蜚蠊科）。每种蟑螂单独在一个含有一种陷阱的竞技场中进行测试。每个测试（一种物种与一种类型的陷阱）重复五次。
INDIA-A 陷阱收集了更多的蟑螂，其次是 INDIA-E。ZAPI 陷阱捕获的每种物种的标本都少于 INDIA 陷阱，只有东方蜚蠊例外，ZAPI 陷阱捕获的东方蜚蠊比 INDIA-E 多。CATCHMASTER 陷阱对所有物种的表现都明显较差。东方蜚蠊是所有陷阱捕获最多的物种，其次是德国小蠊、大蠊和美洲大蠊。在捕获方面，发育阶段没有显著差异。一般来说，没有特定的陷阱对特定物种有特别的偏好。
不可能为每一种蟑螂指定一种特定的陷阱模型，但不同的陷阱在吸引力和捕获方面有不同的表现是显而易见的。因此，陷阱的选择会影响监测结果，从而影响对害虫侵扰种群的评估。
