摘要

在墨西哥,Triatoma pallidipennis 是南美锥虫病的主要病媒。目前的工作重点是利用从脊椎动物宿主身上提取的挥发性物质或已知能吸引食血昆虫的化合物,开发控制这些病媒的引诱剂。然而,这些化合物在吸引受寄生虫感染的三蠹虫方面的功效仍有待评估。在这项研究中,我们评估了辛烯醇(1-辛烯-3-醇)、壬醛以及由氢氧化铵、乳酸和己酸(比例分别为 1:0.2:0.4)组成的混合气味剂(浓度分别为 1、10 和 100 毫微克)对感染和未感染克柔蚊的 N3、N4 和 N5 若虫阶段的吸引活性。我们还评估了最有效化合物和剂量的协同效应。所有实验都是在实验室使用 Y 型玻璃嗅觉仪进行的。我们发现,感染和未感染的 N3 和 N4 若虫都会被低剂量的辛烯醇、壬醛和混合气味剂所吸引。尤其值得注意的是,我们观察到混合气味剂和壬醛之间存在协同效应,可显著提高对受 T. cruzi 感染个体的吸引力。这些发现有助于利用这些化合物开发饵料诱捕器,以便在流行病学研究中监测三蠹虫,或进行大规模诱捕以控制这些病媒。

Trypanosoma cruzi infection enhances olfactory response in Triatoma pallidipennis Stål (Hemiptera: Triatominae) to compounds potentially useful for insect control.

In Mexico, Triatoma pallidipennis is a major vector of Trypanosoma cruzi, the causative agent of Chagas disease. Current efforts are focused on developing attractants to control these vectors, using volatile substances derived from vertebrate hosts or compounds known to attract hematophagous insects. However, the efficacy of these compounds in attracting parasite-infected triatomines remains to be evaluated. In this study, we assessed the attractant activity of octenol (1-octen-3-ol), nonanal and a mixture of odorants consisting of ammonium hydroxide, lactic acid and hexanoic acid (in a ratio of 1:0.2:0.4 respectively), at concentrations of 1, 10 and 100 ng on the N3, N4 and N5 nymphal stages of T. pallidipennis, both infected and non-infected with T. cruzi. We also evaluated the synergistic effect of the most effective compounds and doses. All experiments were performed in a laboratory using a Y-type glass olfactometer. We found that both infected and non-infected N3 and N4 nymphs were attracted to low doses of octenol, nonanal and the odorant mixture. Particularly noteworthy was the synergistic effect observed between the odorant mixture and nonanal, which significantly increased attraction of T. cruzi-infected individuals. These findings contribute to the development of baited traps utilising these compounds for monitoring triatomines in epidemiological studies or for mass trapping to control these vectors.

期刊介绍: Medical and Veterinary Entomology is the leading periodical in its field. The Journal covers the biology and control of insects, ticks, mites and other arthropods of medical and veterinary importance. The main strengths of the Journal lie in the fields of: -epidemiology and transmission of vector-borne pathogens changes in vector distribution that have impact on the pathogen transmission- arthropod behaviour and ecology- novel, field evaluated, approaches to biological and chemical control methods- host arthropod interactions. Please note that we do not consider submissions in forensic entomology.
