The recent global decline in insect populations is of particular concern for pollinators. Wild and managed bees (Hymenoptera, Apoidea) are of primary environmental and economic importance because of their role in pollinating cultivated and wild plants, and synthetic pesticides are among the major factors contributing to their decline. Botanical biopesticides may be a viable alternative to synthetic pesticides in plant defence due to their high selectivity and short environmental persistence. In recent years, scientific progress has been made to improve the development and effectiveness of these products. However, knowledge regarding their adverse effects on the environment and non-target species is still scarce, especially when compared to that of synthetic products. Here, we summarize the studies concerning the toxicity of botanical biopesticides on the different groups of social and solitary bees. We highlight the lethal and sublethal effects of these products on bees, the lack of a uniform protocol to assess the risks of biopesticides on pollinators, and the scarcity of studies on specific groups of bees, such as the large and diverse group of solitary bees. Results show that botanical biopesticides cause lethal effects and a large number of sublethal effects on bees. However, the toxicity is limited when comparing the effects of these compounds with those of synthetic compounds.

“…There are few studies on the safety and selectivity of products based on plant extracts on A. mellifera . Potrich et al (2020) found that different plant extracts had an effect on the survival rates of A. mellifera , although it is lower compared to the effect of synthetic chemical insecticides (Henry et al 2012;Christen et al 2016;Thompson et al 2019). In turn, there is little information regarding the bactericidal activity against P. larvae of the hydroalcoholic extracts of hop leaves, and even less information about the benefits of secondary metabolites found in natural plant extracts on bees in terms of activation in the regulation of gene expression involved in longevity, immune function, pesticide detoxification, stress tolerance, and the production of certain antimicrobial peptides (AMPs) that help control infections caused by various pathogens (Manson et al 2009;Alaux et al 2011;Liao et al 2017).…”

Immune-related gene expression in honey bee larva (Apis mellifera) exposed to plant extracts from Humulus lupulus with antimicrobial activity against Paenibacillus larvae

American foulbrood caused by Paenibacillus larvae brings with it several problems on beekeepers for the use of synthetic antibiotics, likewise led to the appearance of resistant strains and the presence of chemical residues in the commercial products of the hive. In recent years, the use of natural compounds for the control of P. larvae has increased. Herein, we propose to determine the value of the Minimal Inhibitory Concentration (MIC) of a hydroalcoholic extract of Humulus lupulus (hop) leaves of Victoria variety on P. larvae strain, and to evaluate its toxicity and effect on the expression of three genes of the immune system on honey bee larvae. For the extract, the MIC value was 83.79 μg/mL. For larvae, the extract did not show toxicity, on the other hand presented a down-regulation in the gene expression for the three genes evaluated. The results obtained here are a first report on the evaluation in the effect of natural extracts on the expression of genes related to the immune system in bee larvae.secondary metabolites / hops / Apis mellifera , Paenibacillus larvae , antimicrobial peptides

“…In addition, B. bassiana is already used commercially for insect control in several crops. Knowing that A. mellifera visits several crops treated with these control agents, studies have been carried out to check the effect of entomopathogenic fungi (Alves, Marchini, Pereira, & Braumgratz, 1996;Al Mazra'awi, Shipp, Broadbent, & Kevan, 2006;Al Mazra'awi, 2007;García-Fernández, Santiago-Álvarez, & Quesada-Moraga, 2008;Potrich et al, 2018) and natural products (Damiani et al, 2011;Xavier et al, 2015;Potrich et al, 2020) for A. mellifera. However, there few studies that assessed the effect of these agents in the field, especially those related to the quality of Africanized A. mellifera queens.…”

“…The P. granatum extract was selected because the main compound of the secondary metabolism has potential insecticide and, in previous scientific studies, was classified as an extract with insecticidal potential for insect control. Moreover, these control agents presented negative effect on Africanized A. mellifera workers when assessed under laboratory conditions (Potrich et al, 2018(Potrich et al, , 2020.…”
