“…The pain from the bite is caused by the toxin being injected into the skin; possible retention of the proboscis makes the pain worse. 4,9 In addition, when A cristatus is disturbed, it exudes pungent material from a pair of bright orange subrectal glands while stridulating to repulse predators. 9 Although Triatoma species and A cristatus have separate roles in nature and vastly different impacts on health, they often are mistaken for the same arthropod when seen in nature.…”

Members of the Triatoma and Arilus genera (family Reduviidae) often are mistaken as the same arthropod, though their bites have vastly different health implications. Bites of the wheel bug (Arilus cristatus) are painful compared to Triatoma bites, which are painless but can cause disease and result in an anaphylactic reaction, posing a risk to human health because these pliable insects commonly infest residential dwellings. A common dermatologic presentation of bites from Triatoma species and A cristatus is an erythematous pruritic papule that can progress to an urticarial wheal, though the presentation can differ from patient to patient. Treatment depends on whether the reaction is localized or systemic, ranging from topicals to systemic agents if anaphylaxis occurs.

Alien species must adapt to new biogeographical regions to acclimatise and survive. We consider a species to have become invasive if it establishes negative interactions after acclimatisation. Xylella fastidiosa Wells, Raju et al., 1986 (XF) represents Italy’s and Europe’s most recent biological invasion. In Apulia (southern Italy), the XF-encountered Philaenus spumarius L. 1758 (Spittlebugs, Hemiptera: Auchenorrhyncha) can acquire and transmit the bacterium to Olea europaea L., 1753. The management of XF invasion involves various transmission control means, including inundative biological control using Zelus renardii (ZR) Kolenati, 1856 (Hemiptera: Reduviidae). ZR is an alien stenophagous predator of Xylella vectors, recently entered from the Nearctic and acclimated in Europe. Zelus spp. can secrete semiochemicals during interactions with conspecifics and prey, including volatile organic compounds (VOCs) that elicit conspecific defence behavioural responses. Our study describes ZR Brindley’s glands, present in males and females of ZR, which can produce semiochemicals, eliciting conspecific behavioural responses. We scrutinised ZR secretion alone or interacting with P. spumarius. The ZR volatilome includes 2-methyl-propanoic acid, 2-methyl-butanoic acid, and 3-methyl-1-butanol, which are consistent for Z. renardii alone. Olfactometric tests show that these three VOCs, individually tested, generate an avoidance (alarm) response in Z. renardii. 3-Methyl-1-butanol elicited the highest significant repellence, followed by 2-methyl-butanoic and 2-methyl-propanoic acids. The concentrations of the VOCs of ZR decrease during the interaction with P. spumarius. We discuss the potential effects of VOC secretions on the interaction of Z. renardii with P. spumarius.

Triatomines (Hemiptera: Heteroptera: Reduviidae), commonly known as conenose or kissing bugs, includes species of outstanding medical importance given their role as vectors of the protozoan parasite Trypanosoma cruzi Chagas (Kinetoplastida: Trypanosomatidae), the aetiological agent of Chagas disease. Herein, we present an updated review of the chemical ecology of triatomines, with special reference to molecules involved in the communication of these insects. Infochemicals, including hormones and semiochemicals (pheromones and allelochemicals), have a pivotal role in mediating information and shaping interactions within and between triatomines, during distinct behavioural contexts. We analyse the new findings about the chemical composition of alarm, aggregation and sex pheromones, as well as on cuticular hydrocarbons, host attractants and repellents. We also discuss how triatomine hormones may serve as communication signals and highlight the importance of the reverse chemical ecology approach in studying the complex chemoecology of these arthropod vectors. In the final section, we outline how knowledge about triatomine chemical ecology can be used for implementing real-world control operations with proven epidemiological impact.
