The common bed bug (Cimex lectularius, Hemiptera; Cimicidae) infests homes and service industries, and the number of infestations has greatly increased over the past 20 years. At present, no cost-effective control methods are available, and eradication programs are expensive and laborious. We investigated the control potential of desiccant dust in combination with CO2 as a bed bug activity stimulant. An initial experiment with two desiccant dusts was followed by arena studies with varying doses, available hiding places and the presence or absence of host signals. Finally, we conducted a field experiment with Syloid 244FP with or without CO2 gas. Syloid was superior compared to diatomaceous earth, and effective at the concentration of 1.0 g/m2 in the field experiment. The number of harborages and partial application of desiccant dust decreased mortality in the laboratory. Bed bug activation by CO2 appeared of minor importance in the arena studies, but was crucial for the eradication in the student dormitories. In fact, all 5 bed bug-infested dormitories with a combined treatment of desiccant dust and CO2 were freed of bed bugs, whereas eradication was not successful in any of the 6 dormitories with only desiccant dust treatment. The different results in the laboratory and field experiment were most likely caused by the longer activation and higher dose of CO2 used in the field experiment than the laboratory experiment. Our study showed that application of desiccant dust in combination with release of CO2 gas to mimic human presence is a promising option for bed bug control.

干燥剂粉尘和使用CO2气体作为臭虫的移动性刺激剂:潜在的控制解决方案?

常见的臭虫(Cimex lectularius,半翅目,Ci科)侵扰了家庭和服务业,在过去的20年中,侵扰的数量大大增加了。当前,没有可用的成本有效的控制方法,而根除计划既昂贵又费力。我们研究了干燥剂粉尘与CO 2作为臭虫活性刺激剂的控制潜力。最初的实验是用两种干燥剂粉尘进行试验,然后进行不同剂量,可利用的藏身处以及是否存在宿主信号的竞技场研究。最后,我们在有或没有CO 2气体的情况下对Syloid 244FP进行了现场试验。Syloid优于硅藻土,并且在1.0 g / m 2的浓度下有效在野外实验中。避风港的数量和除尘剂的部分应用降低了实验室的死亡率。在竞技场研究中,CO 2活化臭虫的作用似乎并不重要,但对于根除学生宿舍至关重要。实际上,所有经过5次臭虫出没的经过干燥剂粉尘和CO 2组合处理的宿舍都摆脱了臭虫的滋生,而在仅进行了干燥剂粉尘处理的6个宿舍中,没有根除方法。实验室和现场实验中不同的结果很可能是由于激活时间更长和剂量更高的CO 2引起的在野外实验中使用的比实验室实验要多。我们的研究表明,结合使用干燥剂粉尘和释放CO 2气体来模拟人的存在是控制臭虫的有前途的选择。
