Aspectos ecológicos da tripanossomíase americana: XX - Desenvolvimento e ciclos anuais de colônias de Panstrongylus megistus em ecótopos artificiais, no ambiente peri e extradomiciliar

Abstract: RESUMO: Em colônias de Panstrongylus megistus, espontaneamente desenvolvidas em galinheiros experimentais, pôde-se observar as condições de desenvolvimento, variação e permanência de seus componentes. Foram obtidos também dados sobre os ciclos anuais e a sobrevivência, O aspecto cíclico caracterizou-se pela maior produção de formas adultas no último trimestre do ano, ocasião que coincide com o encontro dessa espécie no ambiente domiciliar. Face a tais achados, considera-se que o período de produção de adultos … Show more

“…The increased occurrence of adult specimens of P. megistus in the domiciliary environment over the last trimester of the year was observed in other studies in different regions of Brazil 30,37,39,40 , indicating that these triatomines present a higher potential to colonize domiciles and their annexes in the rainy season. In DF, this period is marked by an increase in temperature as from October 9 , which can stimulate the flight activity of P. megistus, as already observed for other species of triatomines 38,41 .…”

“…The development of colonies of P. megistus occurs in humid environments 23,33 , and it is possible that gallery forests may be the natural habitat of populations of this species. With the disorganized growth of administrative regions many domiciles are found close to these areas, and this may favor dispersal by flight and domiciliary invasion of these triatomines, stimulated by environmental changes such as reduction of food sources in the wild environment, presence of food sources in peridomicile, and/or rising temperature 23,[33][34][35][36][37][38] . In this context, urban areas surrounded by remainder forests and with marked climate change over the year (as in DF) are likely to favor the invasion of P. megistus in artificial ecotopes.…”

“…The detection of nymphs II in June does not necessarily imply reproductive events during the dry season, since T. costalimai may remain in this nymphal stage for up to 145 days. In the case of other triatomine species such as Panstrongylus megistus (Burmeister, 1834), studies in different regions of Brazil indicate that the invasion of specimens in domiciles occurs more in the wet season, especially during the last quarter of the year [19][20][21] . The increase of temperature seen in areas of the Brazilian savanna during this period 22 could stimulate the reproduction, dispersal and development of T. costalimai colonies, as already observed for other triatomine species 23,24 .…”

“…Alguns municípios da citada área já foram alvo de vários estudos por Forattini e col. 2,3,4,5,6 e Rocha e Silva e col. 8,9 , onde foram abordados aspectos do comportamento do Panstrongylus megistus. Os dados foram contabilizados por município, por mês e por ano.…”
