Utilização de bioensaios e marcadores moleculares para detecção da resistência de coleópteros de produtos armazenados a inseticidas Rev. Bras. entomol.
Ceruti,Fabiane Cristina; Lázzari,Sonia Maria Noemberg.
The qualitative and quantitative losses caused by stored product insects are of great concern, and since there is only a few active ingredients available for their control it is very important to have a frequent insect resistance monitoring. The objective of this research is to evaluate combination of bioassays and molecular marker techniques to detect insecticide resistance in stored product beetles. The Coleoptera species used for the tests were Sitophilus oryzae (L.) (Curculionidae), Rhyzopertha dominica (F.) (Bostrichidae) and Oryzaephilus surinamensis (L.) (Silvanidae). For the bioassays it was used the impregnated filter paper technique, applying 1 mL of deltamethrin (K-Obiol 25 CE TM) using four concentrations and five replicates, including a...

Variação morfométrica e demográfica em Phaleria testacea Say (Coleoptera, Tenebrionidae) de duas praias do Rio de Janeiro Zoologia
Almeida,M.D. de; Caldas,A; Almeida,J.R. de.
The species Phaleria testacea Say, 1824 (Coleoptera, Tenebrionidae) varies a lot in size, and its populations along the coast of Brazil, where it lives buried in sandy beaches, have temporal and geographical variation in density. In order to find out which factors were contributing to these variations, we sampled populations from three different areas in Rio de Janeiro, during summer and winter. Simultaneously, we made an analysis of the different substracts where the individuals were found, including their total fresh weight. The results show a significant difference in size of individuals between and within populations, when summer and winter were compared. There is also a positive association between the population density of P. testacea and the amount...

What have we learned from the dead? A compilation of three years of cooperation between entomologists and crime scene investigators in Southern Brazil Rev. Bras. entomol.
Corrêa,Rodrigo C.; Caneparo,Maria F.C.; Vairo,Karine P.; Lara,Alexandre G. de; Moura,Mauricio O..
ABSTRACT With homicide rates higher than the world average, Brazil stands out as one of the most violent countries worldwide. Time of death estimation based solely on body changes can be biased or inaccurate; forensic entomology can play a determinant role in such cases. Accurate knowledge of necrophilous fauna is essential to validate experimental data and allows for the application of entomological evidence in forensic investigations, which benefits scientists, investigators, and society in general. Entomological evidence from Curitiba and 22 nearby cities were collected by crime scene investigators from the Scientific Police of Paraná. The corpses were found in diverse environments and specimens from each species were collected from all life stages. We...
