Impact of copper sulfate on survival, behavior, midgut morphology, and antioxidant activity of Partamona helleri (Apidae: Meliponini)

Lethal and sublethal effects on stingless bee (Partamona helleri) larvae caused by chronic exposure to three agrochemicals

“…The results confirmed that high doses of CuSO4 impaired the survival of stingless bees, as has been previously reported for adult bees (Rodrigues et al 2016;Botina et al 2019;Bernardes et al 2022b).…”

“…The effects of acute exposure to CuSO4 were previously assessed in adult P. helleri, where lethality was proportional to the dose, and respiration rate (Botina et al 2019), walking, and feeding behaviors (Rodrigues et al 2016;Bernardes et al 2022b) were altered. The current study provides the first evidence of the sublethal effects of chronic exposure of CuSO4 to larvae.…”

“…Agrochemicals such as fertilizers are widely used as sources of nutrients, providing essential elements for plants to complete their life cycle (Isherwood and Johnston 1998), but the fertilizers, particularly leaf fertilizers, are sources of metals such as copper (Cu), which can be found in the environment in concentrations with potentially harmful effects on bees through oral exposure and subsequent bioaccumulation (Hladun et al 2015;Dow 2017;Burden et al 2019;Di et al 2020). The treatment of adult, stingless bees with copper sulfate (CuSO4) demonstrated a toxic effect on the survival and behavior of Friesella schrottkyi (Rodrigues et al 2016) and Partamona helleri (Botina et al 2019;Bernardes et al 2022b). However, there have been no reports on the interaction between CuSO4 and larval development in stingless bees.…”

Source Analysis and Contamination Assessment of Potentially Toxic Element in Soil of Small Watershed in Mountainous Area of Southern Henan, China

“…Figure 1 and Figure 2 show that the areas with high Cu content are mainly distributed near the mining and planting area, and the point concentration near the mining area is higher than that of the farmland. Studies have shown that a large amount of CuSO 4 is used as an insecticide for fruit trees in pesticide production [ 62 , 63 ]. Through the field survey, it can be seen that pears, peaches, apricots and other fruit trees are planted in the study area.…”

O fungicida fluazinam induz morte celular no intestino médio e altera o comportamento da abelha sem ferrão Partamona helleri (Hymenoptera: Apidae)

“…Embora o anticorpo anti-caspase-3 clivada utilizado aqui tenha sido desenvolvido para a caspase-3 de humanos, ela apresenta reação cruzada para as caspases efetoras semelhantes DrICE e Dcp-1 em Drosophila (Fogarty & Bergmann, 2014) Os efeitos comportamentais causado pelo fluazinam nas operárias forrageiras de P. helleri foram similares aqueles relatados para esta abelha exposta ao espinosade (Araújo et al, 2019b), azadiractina (Bernardes et al, 2017) e sulfato de cobre (Bernardes et al, 2022b). A exposição ao fluazinam reduziu a velocidade média e distância percorrida, aumentando o número de paradas e ficando mais tempo em repouso, semelhante ao encontrado por Araújo et al (2021) após exposição oral a uma mistura de herbicidas e Bernardes et al, (2022b) com sulfato de cobre em P. helleri. Essas alterações comportamentais podem ser uma estratégia para minimizar o gasto de energia (Brito et al, 2020), pois o consumo alimentar como relatado foi menor e o epitélio intestinal apresentou danos que podem prejudicar a disponibilidade energética que as abelhas necessitam para realizar suas atividades (DeGrandi-Hoffman et al, 2015;Mao et al, 2017).…”
