Herbivore, parasitoid and hyperparasitoid insects associated with fruits and seeds of Enterolobium contortisiliquum (Vell) Morong (Fabaceae)

Braz. j. biol; 79 (3), 2019
Abstract This study aimed to inventory the herbivore insects associated with Enterolobium contortisiliquum (Vell.) Morong (Fabaceae) fruits and seeds and their primary and secondary parasitoids. Six samples collected between May and October 2013 yielded 210 fruits, from which 326 insects of six orders e...

Volatiles induction in response to mechanical damage is reduced by domestication in murtilla

Volatiles compounds are involved in defensive induction against insects, playing an important role in insect-plant interaction being induced by response to mechanical damage. However, they could decrease according to the domestication degree in cultivated plants. Currently, it has been established that s...

The diversity of Odonata adults's at Pampa Biome from Brazil

Rev. biol. trop; 67 (1), 2019
Abstract The growth of humankind has brought with it several environmental problems that have worsened over time, including the loss of insect biodiversity. The Odonata order have been indicated by several authors as relevant bioindicators for assessing and monitoring environmental conditions of specific...

Feeding preference of the shredder Phylloicus sp. for plant leaves of Chrysophyllum oliviforme or Miconia chartacea after conditioning in streams from different biomes

Braz. j. biol; 79 (1), 2019
Abstract Macroinvertebrate shredders consume preferably leaves conditioned by fungi and bacteria which offer greater palatability to them. Plant species in Cerrado present high concentration of chemical elements such as lignin and cellulose, phenols and tanins thus making them less attractive for shredd...

Comparative assessment of the replication efficiency of dengue, yellow fever, and chikungunya arboviruses in some insect and mammalian cell lines

Abstract INTRODUCTION: Insect cell cultures play an essential role in understanding arboviral replication. However, the replicative efficiency of some of these viruses such as dengue (DENV), yellow fever (YFV), and chikungunya (CHIKV) in a new cellular substrate (Lulo) and in the other two recognized ce...

Bases moleculares da absorção de nutrientes, tamponamento e fluxos de fluídos no intestino médio de Musca domestica

O intestino dos insetos representa uma interface pouco protegida dos agentes externos. A identificação dos mecanismos moleculares envolvidos nos processos fisiológico-digestivos permite encontrar alvos potenciais para o controle de insetos. As moléculas envolvidas na absorção de nutrientes, tampona...
