The olfactory response of insect vectors such as phlebotomine sand flies is a key facet for investigating their interactions with vertebrate hosts and associated vector-borne pathogens. Such studies are mainly performed by assessing the electrophysiological behaviour these arthropods towards volatile organic compounds (VOCs) produced hosts. Nonetheless, few available species subgenera Lutzomyia Nyssomyia in South America, leaving void Old World fly genus Phlebotomus. In this study, we evaluated responses Phlebotomus perniciosus, one most important Leishmania infantum World. To test P. perniciosus behavioural to VOCs, 28 isolated from humans dogs were assessed using (i.e., electroantennogram, EAG) assays Y-tube olfactometer). EAG trials, 14 acetic acid, nonanoic 2-propanol, 2-butanol, pentanal, hexanal, nonanal, trans-2-nonenal, decanal, myrcene, p-cymene, verbenone, 2-ethyl-1-hexanol, acetonitrile) elicited high antennal ≥ 0.30 mV) female flies, being those VOCs selected assays. From tested olfactometer, nonanal was significantly attractive females, whereas myrcene p-cymene repellents (p < 0.05). attraction indexes varied 0.53 attractive) -0.47 repellent).

Volatile organic compounds (VOCs) are chemicals emitted as products of cell metabolism, which reflects the physiological and pathological conditions any living organisms. These play a key role olfactory cues for arthropod vectors such mosquitoes, sand flies, ticks, act in transmission pathogens to many animal species, including humans. Some VOCs may influence behaviour, e.g., host preference oviposition site selection gravid females. Furthermore, deadly vector-borne Plasmodium falciparum Leishmania infantum suggested manipulate profile make them more attractive mosquitoes fly vectors, respectively. Under above circumstances, studies on these have demonstrated their potential usefulness investigating behavioural response ticks toward vertebrate hosts, well tools diagnosis diseases (VBDs). Herein, we provide an account scientific data available study seeking behaviour attractants, repellents, or early VBDs.

Triatomines are insect vectors of the flagellate protozoan Trypanosoma cruzi, causative agent Chagas disease. This occurs when triatomine defecates on skin vertebrate host it bites its for feeding. lesion causes penetration T. whose infective phase is tripomastigote, and non-infective replicative epimastigote. Although effects cruzi development survival different species bugs known, has not been fully described how parasite affects many that inhabit Mexico. Therefore, present study aimed to investigate effect presence survival. For this, five triatomines each instar species, Triatoma barberi longipennis, were inoculated, from their second adult stage, female or male. Each was infected with 3-5 x105 parasites they incubated 100 days kinetic in feces phases recorded. The results showed longipennis affected all stages because infection. It greater both mortality, as well time molt phase.
