Biology of Triatoma flavida Neiva, 1911 (Hemiptera: Reduviidae) under laboratory conditions.
The complete life cycle of Triatoma flavida, weekly fed on hens, was studied at 28+/-2 degrees C and 80+/-10% RH. Aspects related to hatching, life span, mortality and feeding behavior for each stage of its life cycle were evaluated. The hatching rate observed for 100 eggs was 93% with an average incubation period of 27.2 days. Sixty-two nymphs completed the cycle and the mean egg to adult deve...
متن کاملMorphometric changes of Triatoma flavida Neiva, 1911 (Hemiptera:Triatominae) in the transition from sylvatic to laboratory conditions.
The one-generational metric changes occurring in Triatoma flavida (Hemiptera: Triatominae) when carried from its wild habitat (caves) to laboratory, were examined using traditional morphometric techniques. As for other species of Triatoma, Rhodnius or Panstrongylus studied in similar conditions, a significant reduction of head, thorax and wing size was observed. Sexual dimorphism of the wings, ...
متن کاملPopulation biology of Rhodnius domesticus Neiva & Pinto, 1923 (Hemiptera: Reduviidae) under laboratory conditions.
The entire life cycle of Rhodnius domesticus, fed weekly on mice, was studied under controlled conditions. Aspects related to hatching, life time, mortality, feeding behaviour and fecundity for each stage of the insect life-cycle were evaluated. The hatching rate observed in 100 eggs was 57% and the mean time of hatching was 15.6 days. Forty-six nymphs (80.7%) completed the cycle and the mean t...
متن کاملUpdate on the biology of Triatoma dimidiata Latreille (Hemiptera: Reduviidae) under laboratory conditions.
Feeding time, postfeeding defecation delay, and life cycle for each stage of a cohort of recently colonized Mexican Triatoma dimidiata were evaluated, and results were compared to existing published information on this species. Seventy-five nymphs (41.7%) completed a cycle with an average time from N-I to adult of 142 +/- 64 days. The average span in days for each stage was 20.2 for N-I, 17.9 f...
متن کاملChromosome homogeneity in populations of Triatoma brasiliensis Neiva 1911 (Hemiptera - reduviidae - triatominae).
Triatoma brasiliensis is the most important vector of Chagas disease in the semiarid zone of the Northeast of Brazil. Several authors have reported the occurrence of four chromatic patterns with morphological, ecological, and genetic differences. In order to determine the existence of cytogenetic differentiation between these chromatic forms, we analyzed their karyotypes and the chromosome beha...
