“…The mixture was then diluted to obtain 0.001 and 0.0001 (g/dm 3 ) of this dose. PPP concentrations used in the experiment corresponded with their residual concentrations in honey nectar and/or pollen [6,[23][24][25][26][27][28][29][30]. PPPs were administered alone or in binary or ternary mixtures, creating 14 experimental groups.…”

The honey bee obtains food from bee forage, which comprises crops grown in multi-hectare agricultural fields where various types of plant protection products such as pesticides are used. Some of these negatively affect the honey bee organism. In our research, we aimed to evaluate the effects of three pesticide groups: fungicides (tebuconazole), insecticides (acetamiprid), herbicides (glyphosate), and their mixtures on the functioning of honey bee workers (A. mellifera carnica). Pesticides in various proportions and dilutions were added to sugar syrups and then fed to the bees. Mortality and food intake were recorded daily, while hemolymph analysis was performed after seven days of exposure. Food intake, mortality, and the results of various biochemical analyses differed between the experimental group and the control group receiving untreated sugar syrup. PPP’s mixture of glyphosate tebuconazole and acetamiprid is more toxic to bees than single pesticides. Certain protection products such as pesticides can disrupt the antioxidant and detoxification systems associated with immunity in honey bees. Consequently, honey bees experience weaker conditions and their proper functioning deteriorates. The results obtained from biochemical changes provide a basis for field studies.

“…A conversão de habitats naturais em áreas urbanas e rurais tem resultado em perdas de habitat expressivas, causando o desaparecimento de espécies (Cardoso & Gonçalves, 2018) e afetando a relação planta-polinizador de áreas naturais e plantações agrícolas (Kammerer et al 2020). O crescente uso de pesticidas e agrotóxicos contribui ainda para piorar esta situação, afetando diretamente e negativamente essas populações (Maria Arena & Fábio Sgolastra 2014; Barbosa et al 2015;Azucena et al 2020). Apenas no ano de 2020, foram aplicados 1.052.520 toneladas de defensivos agrícolas, o que movimentou US$12,113 milhões em 2020 no Brasil, um crescimento de 6,8% em relação ao ano de 2019 e de 336% desde 2000 (Sindiveg 2020).…”

As abelhas são os principais invertebrados que executam o indispensável serviço ecológicoda polinização, serviço esse que permite a variabilidade genética em plantas com flores eassim garantem a viabilidade da vegetação. Apesar disso, nos dias atuais, esses seres seveem ameaçados por grandes perdas de habitat e a utilização de defensivos agrícolas emgrandes plantios. Em especial aquelas que se encontram dentro do bioma Cerrado, visto queeste sofre diariamente com a degradação de grandes áreas e possui apenas uma pequenaparcela de seu território protegida por força de lei. Dentre todos os grupos de abelhaspodemos ressaltar as Meliponini, abelhas nativas de zonas tropicais que evolutivamenteperderam a capacidade de usar o ferrão como forma de defesa. Em geral, invertebrados sãoafetados por essa intensa perda de habitat, porém pouco se sabe sobre como as abelhasnativas sem-ferrão (ANSF) se comportam diante de tal pressão negativa. Esse estudo procuraentender como a diversidade de Meliponini se comporta diante da perda de habitat paraurbanização e para agropecuária no Distrito Federal. Para a amostragem dos espécimesforam utilizadas armadilhas do tipo pan-traps, sendo 15 unidades distribuídas com distânciade 5 metros entre cada uma por ponto amostrado, além disso foram utilizados dados daplataforma de ciência cidadã iNaturalist e informações sobre a localização de colônias demoradores locais. Foram documentadas 73 colônias de 15 espécies ao total, apresentandoum Índice de diversidade de Shannon de H=2,03 sendo as Áreas Rural (H’=2,08) e Preservada(H’=1,79) as mais diversas. As espécies mais amostradas foram Tetragonisca angustula(n=25) seguida de Scaptotrigona postica (n=21), ambas com a maior parte das colôniascatalogadas em ambiente urbano, mostrando uma alta adaptabilidade das espécies citadas aaltos níveis de alterações antrópicas. Não foram encontradas diferenças estatisticamentesignificantes entre a Área urbana e a Área rural (p=0,154). A baixa quantidade de dadoscontidos na plataforma de ciência cidadã e por terceiros, inviabilizou amostragem suficientepara análises da área preservada, entretanto foi possível a realização de uma inicial lista deespécies que ocorrem na área, visto que não existem dados similares para a área

“…A high concentration of imidacloprid and 6-chloronicotinic acid was detected in pollen loads, honey, and honey bee matrices. Vargas-Valeroet al established a relation between the presence of pesticides with colony collapse (13) . 24 pesticides were detected in honey analyzed by LC-QTOF and GC-MS/MS.…”

Objectives: To quantify a broad spectrum of pesticides of various chemical classes such as neonicotinoids, organochlorines, organophosphates, triazoles, carbamates, dicarboximides, and dinitroaniline in honey at ppb level using Liquid chromatography-tandem mass spectroscopy (LC-MS/MS) and Gas chromatography-tandem mass spectroscopy (GC-MS/MS). Methods: QuECh-ERS based sample preparation followed by the Multiple Reaction Monitoring (MRM) method was developed for quantitation of pesticides in honey. This method was validated as per SANTE/12682/2019 guidelines. Findings: Acceptable values were obtained for matrix-matched linearity, the limit of detection (2 ng/g) and limit of quantification (5 ng/g), and an intraday precision of less than 7%. A recovery of 70-120% was obtained for more than 85% of the compounds. However, there were compounds such as Alanycarb, Propiconazole, Benzoximate, etc. showed recovery values between 60-70%, however, these values were found consistent among multiple batches. Twelve honey samples were analyzed employing the developed method, out of which 8 samples were sourced from apiculture farms located in five districts of Kerala state, India. Rest four samples were commercial honey brands in India. Many of the pesticide residues were identified below the limit of quantitation. Some of the pesticides were quantified above the LOQ levels in samples, however, Propoxur and deltamethrin were the only pesticides found above the maximum residue limit as per the India residue monitoring program to export honey samples to EU countries. Novelty: Studies on the presence of pesticide residues in Kerala honey samples have not yet been published. The proposed method was able to detect an extensive range of pesticides with remarkably high sensitivity, selectivity, and precision.
