Orientation behaviour of the blood-sucking bug Triatoma infestans to short-chain fatty acids: Synergistic effect of L-lactic acid and carbon dioxide

Mostrar todas las versiones(3)

The role of short-chain fatty acids in the host-seeking behaviour of Triatoma infestans larvae was investigated using a locomotion compensator. Several short-chain fatty acids were tested alone over a wide range of doses, or in combination with L-lactic acid (L-LA; 100 μg). Bugs showed no attractive...

Several short-chain fatty acids were tested alone over a wide range of doses, or in combination with L-lactic acid (L-LA; 100 μg). Bugs showed no attractive response to single carboxylic acids, but when L-LA was added to airstreams carrying specific intensities of either propionic (C3; 100 μg), butyric (C4; 1 μg) or valeric acid (C5; 1 μg), these mixtures elicited an attractive response, evincing a synergistic effect. No orientation response was observed when caproic acid (C6) was offered with L-LA at the doses tested. Two blends were created: (1) C3, C4 and C5 combined at the effective doses when added with L-LA [C3C4C5 (1)], and (2) C3, C4 and C5 combined at a third of those intensities [C3C4C5 (2)]. Both blends were tested alone, with L-LA (100 μg), with a sub-threshold concentration of CO2 (300 p.p.m. above the ambient level), and combined with both compounds together. Oriented responses of bugs were only observed with the blend (2) added with L-LA and with the combination of this lure with CO2. This last combination evoked a behavioural response similar in intensity to that induced by a live mouse. © Oxford University Press 2004; all rights reserved. Fil:Lazzari, C.R.
