The effect of environment on development and survival of pupae of the necrophag...
Krüger, Rodrigo Ferreira; Wendt, Lisiane Dilli; Ribeiro, Paulo BretanhaSpecies of Ophyra Robineau-Desvoidy, 1830 are found in decomposing bodies, usually in fresh, bloated and decay stages. Ophyra albuquerquei Lopes, for example, can be found in animal carcasses. The influence of environmental factors has not been evaluated in puparia of O. albuquerquei. Thus, the focus of this work was motivated by the need for models to predict the development of a necrophagous insect as a funct...
Survival and reproduction of Synthesiomyia nudiseta (Diptera, Muscidae)
Krüger, Rodrigo Ferreira; Krolow, Tiago Kütter; Azevedo, Rodrigo R.; Duarte, Juliano Lessa Pinto; Ribeiro, Paulo BretanhaThe reproduction and survival of Synthesiomyia nudiseta (Wulp, 1883) were studied between 22 and 28°C, 70% R.H. and 12h photoperiod. The raw data were analyzed based on age-class, sex life table, Weibull distribution and entropy curve (H). The intrinsic rate of increase (rm), finite rate of increase (λ), net reproduction rate (R0) and mean generation time (T) were 0.534, 1.7, 59.439 and 7.65 respectively, sugge...
Chave pictórica para os gêneros de Tabanidae (Insecta: Diptera) do bioma Campos...
Krüger, Rodrigo Ferreira; Krolow, Tiago Kütter; Ribeiro, Paulo BretanhaForam realizadas coletas de tabanídeos ao longo de quatro anos (2002-2006) no extremo sul do Rio Grande do Sul, Brasil. Apresenta-se uma lista com 30 espécies, além de chave pictórica e diagnoses para identificação dos 15 gêneros encontrados na região. Nove espécies são registradas pela primeira vez no estado do Rio Grande do Sul.; Tabanids were collected and preserved along four years (2002-2006) in southern R...
Larvicidal efficiency of the fungus Amanita muscaria (Agaricales, Amanitaceae) ...
Carapeto, Luiz Paiva; Cárcamo, Marcial Corrêa; Duarte, Jucelio Peter; de Melo, Luize Garcia; Bernardi, Eduardo; Ribeiro, Paulo BretanhaThis work reports the larvicidal action of two formulations of Amanita muscaria against Musca domestica. Two methods of extraction were tested: an aqueous extract from dried, powdered basidiomes (DPB); and an extract from fresh basidiomes liquefied in water (FLB). The mortality caused by the DPB extract varied from 14.67% to 100%. The efficiency of the FLB extract varied from 10.67% to 89.33%. The mean lethal c...
Survival and weight change among adult individuals of Periplaneta americana (Li...
Duarte, Jucelio Peter; Felchicher, Francielly; Ribeiro, Paulo Bretanha; Cárcamo, Marcial CorrêaPeriplaneta 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 initi...
Thermal requirements of Aprostocetus hagenowii (Ratzeburg, 1852) (Hymenoptera, ...
Cárcamo, Marcial Corrêa; Felchicher, Francielly; Duarte, Jucelio Peter; Krüger, Rodrigo Ferreira; Vianna, Élvia Elena Silveira; Ribeiro, Paulo BretanhaThis study aimed to determine the thermal requirements of Aprostocetus hagenowii in oothecae of Periplaneta americana, as well as the influence of different temperatures on the biology of this parasitoid. Oothecae with maximum age of eight days and weight ranging from 0.09 to 0.10 g were individualized in Petri plates with a couple of A. hagenowii, being exposed to parasitism. Parasitoids and oothecae stayed to...
Ocorrência de muscóideos necrófagos em carcaça de Didelphis albiventris Lund, 1...
dos Anjos, Vanessa Abelaira; Ribeiro, Paulo Bretanha; Krüger, Rodrigo Ferreira; Silva, Ândrio Zafalon daAs informações relativas quanto à similaridade da fauna colonizadora de animais silvestres em decomposição são incipientes entre os diferentes modelos de carcaças. É esperado que espécies que possuam tecidos e dietas alimentares diferentes ao morrerem sejam fontes de colonização de diferentes espécies necrófagas. Para a verificação desta hipótese foi acompanhada a decomposição de uma carcaça de Didelphis albive...
Comparison of methods to monitor populations of Alphitobius diaperinus (PANZER,...
Pinto, Diego Moscarelli; Ribeiro, Paulo Bretanha; Silveira Júnior, PauloAlphitobius diaperinus (PANZER, 1797) (Coleoptera: Tenebrionidae) it colonizes the substratum found at farms, growing up in high populations, causing sanitary problems with economical reflexes. In this work the comparative evaluation of monitoring methods was accomplished of A. diaperinus. The evaluations were made in a period of twelve months, in broiler barn of the Conjunto Agrotécnico Visconde da Graça, in P...
