The aim of this work was to identify and report the occurrence of Trypanosoma rangeli and Trypanosoma cruzi in naturally infected Rhodnius nasutus (Hemiptera, Reduviidae, Triatominae) in the state of Ceará, Brazil. Triatomines feces, salivary glands, and hemolymph were collected for fresh examination, and specific detection of T. rangeli and T. cruzi DNA by polymerase chain reaction was carried...

A checklist of Heteroptera type specimens deposited in the collection of División Entomología, Museo de La Plata.

Abstract Animal behaviours often dependent on age. In many insect species, walking shows an age-dependent decline, and food intake may also be However, few studies have investigated the relationship between age or intake. present study, we compared traits among individuals of different ages in assassin bug Amphibolus venator (Hemiptera, Reduviidae). The results showed decline walking, similar t...

New records of species Reduviidae from five Neotropical countries are provided: Notocyrtus gibbus (Fabricius) (Harpactorinae: Harpactorini) Costa Rica; Kodormus bruneosus Barber (Stenopodainae), Ploeogaster gesana Kirkaldy Harpactorini), Pseudopothea paulai GilSantana (Ectrichodiinae) Ecuador; Leogorrus immaculatus Champion (Reduviinae), Myocoris nugax Stål French Guiana; Zelurus tibialis (Stål...

INTRODUCTION This paper reports, for the first time, the presence of Rhodnius montenegrensis in the State of Acre, Brazil. METHODS Two female R. montenegrensis were collected in a dwelling in the rural area of Rio Branco, Acre, Brazil. RESULTS The occurrence of this species was confirmed, and the number of Triatominae species in the State of Acre increased from four to five. CONCLUSIONS F...

Two species in the genus Rihirbus Stål are recognized, redescribed and illustrated. The diagnosis of the genus is slightly modified. The deposition information of Miller's type specimens is corrected. Rihirbus trochantericus Stål is newly recorded from Cambodia, Laos, Nepal, Thailand, and Vietnam. A key for the identification of species of Rihirbus is provided. The sexual dimorphism and polymor...

INTRODUCTION This study reports for the first time the infection of Rhodnius montenegrensis by Trypanosoma rangeli. METHODS The triatomines were manually collected in Attalea speciosa in the municipality of Buritis, Rondônia. The identification of the trypanosomatid species was confirmed by multiplex PCR. RESULTS All of the collected triatomines were R. montenegrensis. The analysis confirme...

An empirical model of flight initiation coupled with data from a longitudinal study predicted that the flight dispersal of Triatoma infestans from peridomestic sites was more likely to occur in late summer. To partially test this prediction, we operated 11-12 black light traps from 1945 to 2200 hours in March 2003 in two villages in northern Argentina. All peridomestic sites around the light tr...

Insects of the suborder Heteroptera are known for their odor, for being pests, or for being disease carriers. To gain better insight into the cytogenetic characteristics of heteropterans, 18 species of terrestrial Heteroptera belonging to eight families were studied. The presence of heteropycnotic corpuscles during prophase I, terminal or interstitial chiasmas, telomeric associations between ch...
