Sticky traps are standard tools for monitoring German cockroaches (Blattella germanica L.); however, because they lack an attractant, their ability to catch cockroaches is by chance and largely dependent upon the location of placement and length of time they are left in place. Currently, highly effective and economical cockroach attractants are not available. Food-based attractants have the potential to be employed in sticky traps and enhance their effectiveness on trapping German cockroaches. We conducted laboratory and field experiments to evaluate the effectiveness of novel food-based attractants. Laboratory results showed that sticky traps containing the following attractants: apple oil, blueberry oil, orange oil, or their combination, fish oil, peanut butter, Roach lure tablet, and bacon extract had significantly higher trap catch compared to those traps that do not contain an attractant. Apple plus blueberry oil mixture and Roach lure tablet enhanced the trap catch by ≥ 103%, and bacon extract enhanced the trap catch by 92% in the field assays. Apple plus blueberry oil mixture and Roach lure tablet were the most promising attractants based on laboratory and field experiments. Apple plus blueberry oil mixture aged for 2 wk was as attractive to German cockroaches as fresh mixture.

用于监测德国蟑螂的食品引诱剂的实验室和现场评估

粘性陷阱是监测德国小蠊 (Blattella Germanica L.) 的标准工具;然而,由于它们缺乏引诱剂,它们捕捉蟑螂的能力是偶然的,很大程度上取决于放置的位置和它们留在原地的时间长短。目前,还没有高效且经济的蟑螂引诱剂。基于食物的引诱剂有可能用于粘性诱捕器并提高它们诱捕德国小蠊的效率。我们进行了实验室和现场实验,以评估新型食物引诱剂的有效性。实验室结果表明,粘性诱捕器含有以下引诱剂:苹果油、蓝莓油、橙油或它们的组合、鱼油、花生酱、蟑螂诱剂片、与不含引诱剂的诱捕器相比,培根提取物的诱捕器捕获量明显更高。在田间试验中,苹果加蓝莓油混合物和罗奇诱饵片将诱捕效果提高了 103% 以上,培根提取物将诱捕效果提高了 92%。根据实验室和现场实验,苹果加蓝莓油混合物和蟑螂诱饵片是最有希望的引诱剂。陈化 2 周的苹果加蓝莓油混合物对德国蟑螂的吸引力与新鲜混合物一样。
