Resumo: | Periplaneta americana is a species of great importance to public health, since it can act as a vector of many pathogens and it reaches large populations in urban environments. This is probably due to its ability to resist starvation and desiccation. This study aimed to evaluate the effects of absence of water and food on survival and weight change among adult P. americana individuals and check whether the initial weight of individuals influences on their survival. Four groups having twenty P. americana couples were formed and subject to: I) no water or food; II) no food; III) no water; and IV) control group. Insects were isolated according to the groups, which were weighed at the beginning and end of the stress conditions. They remained under these conditions until all individuals in each test group were dead. Stress conditions caused reduction in survival time when compared to the control group. Adults with higher body mass survived longer when deprived only of food, while among those lacking water, weight had no influence on survival. Total weight loss was greater among individuals deprived of water than those deprived only of food. |

Periplaneta americana é uma espécie de grande importância para a saúde pública, já que pode atuar como vetor de diversos patógenos e atinge altas populações em ambientes urbanos. Isso provavelmente se deve à sua capacidade de resistir à fome e a dessecação. O objetivo deste estudo foi avaliar os efeitos da ausência de água e alimento sobre a sobrevivência e variação de peso entre adultos de P. americana e verificar se o peso inicial dos indivíduos influencia em sua sobrevivência. Quatro grupos com 20 casais de P. americana foram formados e submetidos a: I) estresse hídrico e alimentar; II) estresse alimentar; III) estresse hídrico; e IV) grupo controle. Os insetos foram individualizados conforme os grupos, os quais foram pesados no início e no fim das condições de estresse. Permaneceram sob essas condições até que todos os indivíduos de cada grupo de teste estivessem mortos. As condições de estresse causaram redução do tempo de sobrevivência quando comparados ao grupo controle. Adultos com massa corporal superior sobreviveram por mais tempo quando privados somente de alimento, enquanto que naqueles com ausência de água o peso não influenciou na sobrevivência. A perda total de peso foi maior nos indivíduos privados de água do que naqueles privados somente de alimento.Universidade Federal de Santa Catarina2015-03-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n2p10310.5007/2175-7925.2015v28n2p103Biotemas; v. 28 n. 2 (2015); 103-1092175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n2p103/29247Copyright (c) 2015 Jucelio Peter Duarte, Francielly Felchicher, Paulo Bretanha Ribeiro, Marcial Corrêa Cárcamoinfo:eu-repo/semantics/openAccessDuarte, Jucelio PeterFelchicher, FranciellyRibeiro, Paulo BretanhaCárcamo, Marcial Corrêa2017-10-19T16:37:32Zoai:periodicos.ufsc.br:article/36172Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T16:37:32Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
