The life cycle of Neotropical ground beetle, Abaris basistriata (Coleoptera: Carabidae) reared on different substrates

Braz. j. biol; 78 (3), 2018
Abstract Carabids are recognized worldwide as biological control agents of agricultural pests. The objective was to compare the life cycle of Abaris basistriata Chaudoir (Coleoptera: Carabidae) on three substrates: soil, fine vermiculite, or paper napkins. The biological cycle of A. basistriata presented...

Morphological characterization of insect galls and new records of associated invertebrates in a Cerrado area in Bahia State, Brazil

Braz. j. biol; 78 (4), 2018
Abstract In this study, we report the first records and morphological characterization of galls in a Cerrado area in western Bahia, Brazil. The data were collected monthly over two hours between March and September 2015. Fifteen gall morphotypes were found in twelve plant species distributed among seven ...

Dinámica de oviposición de Aedes (Stegomyia) aegypti (Diptera: Culicidae), estado gonadotrófico y coexistencia con otros culícidos en el área Metropolitana de Bucaramanga, Colombia

Resumen Introducción: Las zonas urbanas tropicales favorecen la presencia de Aedes aegypti en el continente americano. Otros culícidos pueden compartir la misma área de distribución con este mosquito, lo cual justifica que se deban monitorear. Objetivo: Conocer la dinámica de oviposición de A. ae...

Plasma biochemistry values in wild female hawksbill turtle (Eretmochelys imbricata) during nesting in Mexican coast

To obtain plasma biochemistry values, blood was collected for 47 nesting females of apparently healthy Eretmochelys imbricata sea turtles using sodium heparin as an anticoagulant. Blood samples were collected in April-Jun for two years (nesting season). Hematologic characteristics, including packed cell ...

Field evaluation of sticky BR-OVT traps to collect culicids eggs and adult mosquitoes inside houses

Abstract INTRODUCTION: Culex quinquefasciatus is a mosquito of importance to public health, as it represents a real and/or potential risk for the transmission of pathogens to humans, such as some arthropod-borne viruses and nematodes that cause filariasis. In Brazil, three municipalities in the Metropol...

Alternative food sources for the ladybird Brumoides foudrasii (Mulsant) (Coleoptera: Coccinellidae)

Braz. j. biol; 78 (2), 2018
Abstract The predator Brumoides foudrasii (Mulsant) (Coleoptera, Coccinellidae) has been naturally found in plants infested by mealybugs. In this study, the striped mealybug Ferrisia dasylirii (Cockerell) (Hemiptera, Pseudococcidae) and Anagasta kuehniella Zeller (Lepidoptera, Pyralidae) eggs were evalua...

Anophelines species and the receptivity and vulnerability to malaria transmission in the Pantanal wetlands, Central Brazil

Mem. Inst. Oswaldo Cruz; 113 (2), 2018
BACKGROUND Studies on malaria vectors in the Pantanal biome, Central Brazil, were conducted more than half a century ago. OBJECTIVES To update anopheline records and assess receptivity and vulnerability to malaria transmission. METHODS Five-day anopheline collections were conducted bimonthly in Salobra...

The influence of a light and dark cycle on the egg laying activity of Aedes aegypti (Linnaeus, 1762) (Diptera: Culicidae)

Mem. Inst. Oswaldo Cruz; 113 (4), 2018
BACKGROUND The epidemiological importance of the mosquito Aedes aegypti as a vector of multiple human pathogens has generated a growing number of studies on the physiology and behaviour of its blood-feeding females. The activity of oviposition is one of the critical elements contributing to the expansion...

The peculiar breeding biology of the Amazonian frog Allobates subfolionidificans (Aromobatidae)

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT Allobates subfolionidificans is a vulnerable and endemic leaf-litter frog from the state of Acre, Brazilian Amazonia. We monitored a population of A. subfolionidificans through regular censuses and mark-recapture of 181 individuals during an entire breeding season to characterize its reproductiv...

Using plastic tips in artificial feeding of Rhipicephalus sanguineus sensu lato (Acari: Ixodidae) females

Abstract This study evaluated the influence of the initial weight, feeding period and temperature on weight gain and biological parameters of the non-parasitic phase of partially engorged Rhipicephalus sanguineus females that were artificially fed using plastic tips as feeding devices. The device did not...
