Behavioral evidence of an ectoparasitic interaction between Triatoma pseudomaculata Correa and Espinola (Heteroptera : Reduviidae) and Periplaneta americana (l.) (Blattodea : Blattidae)PontesG.B.auteurautNoireauFrançoisauteurautIRDLorenzoM.G.auteurauttextjournalArticletext/pdfborn digitalaccessThe present work tested whether Triatoma pseudomaculata Correa & Espinola shows behavioral traits indicating that it is capable of feeding on arthropods. We consistently observed nymphs extending their proboscis in the direction of cockroaches and attempting to bite. Insects presented a preference for biting specific cockroach body parts. Our results suggest that arthropod hemolymph represents an alternative source of food that increases the survival of T. pseudomaculata individuals undergoing long starvation.specializedBehaviorChagas diseasecockroachTriatomineBRESILZONE SEMIARIDE052 080 Neotropical Entomology40670871020111519-566Xhttp://www.documentation.ird.fr/hor/fdi:010054369IRD BondyF B010054369http://www.documentation.ird.fr/hor/fdi:010054369http://www.documentation.ird.fr/intranet/publi/2012/03/010054369.pdfAccès réservé (Intranet de l'IRD)IRD - Base Horizon / Pleins textes2012-04-042012-09-05fdi:010054369fre
