Influence of agrochemicals fipronil and imidacloprid on the learning behavior of Apis mellifera L. honeybees - doi: 10.4025/actascianimsci.v35i4.18683

open access: yesActa Scientiarum: Animal Sciences, 2013
Agrochemicals on crop cultivated areas is a source of contamination for bees and may cause physiological and behavioral disorders and mortality. The LD50 of the pesticides fipronil and imidacloprid was determined and their effect on the learning behavior

Integration of epigenetics into ecotoxicology: insights and fundamental research needs

open access: yesBiological Reviews, EarlyView.
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

Efeito da polinização por abelhas e outros insetos na produção de sementes de cebola Effect of pollination by bees and other insects on the production of onion seeds

open access: yesPesquisa Agropecuária Brasileira, 2003
A deficiência de polinização tem sido apontada como uma das causas da baixa produção de sementes na cultura da cebola. O objetivo deste trabalho foi avaliar a relação da presença de abelhas e outros insetos em flores de duas cultivares de cebola, Allium ...

Chronic toxicity of amitraz, coumaphos and fluvalinate to Apis mellifera L. larvae reared in vitro

open access: yesScientific Reports, 2018
The effects of chronic exposure to common acaricides on Apis mellifera survival, developmental rate and larval weight were tested in the laboratory. Larvae were reared in vitro and fed a diet containing amitraz: 1.5, 11, 25 and 46 mg/L; coumaphos: 1.8, 6,

Knowledge, perceptions, and barriers influence public actions to help bees in Toronto, Canada

open access: yesConservation Science and Practice, EarlyView.
Abstract Despite the enthusiasm surrounding bees, the public's current knowledge is sourced from the non‐native honey bee whose life history differs from many endemic North American species. Ascertaining the public's understandings and perceptions of bees is essential to implementing publicly supported conservation initiatives that may benefit bee ...

Mapping bee diversity with landscape‐level models to inform conservation

open access: yesConservation Science and Practice, EarlyView.
Native bee conservation is complicated by limited distribution data and life history knowledge. However, recent state‐wide pollinator surveys, combined with species distribution models that account for biased datasets and capture regional habitat associations, present a strong foundation for informing essential conservation action.
