“…kurstaki on pollinators there are data of a different nature. Some sources claim their safety for the bumblebee B. terrestris and the bee A. mellifera (WHO, 1999;Erler et al, 2022). Previously, in our studies on the drug AkKobelek ™ based on this strain, its toxicity to pollinators was not observed (Temreshev et al, 2018a;2018b).…”

“…Previously, in our studies on the drug AkKobelek ™ based on this strain, its toxicity to pollinators was not observed (Temreshev et al, 2018a;2018b). Other authors write about an increase in mortality, a decrease in nutritional activity, and physiological changes in the already mentioned species and the wax bee Apis cerana Fabricius, 1793(WHO, 1999Erler et al, 2022). Currently, new methods for assessing the effects of various pesticides are being actively discussed and developed, including those based on B. thuringiensis, on pollinators, due to the shortcomings of the existing risk assessment system (Steinigeweg et al, 2021).…”

“…There is evidence of the possibility of joint use of A. lecanii and the rider Encarsia formosa Gahan, 1924 (Stansly andLiu, 1997;Mitina et al, 2018;Gogi et al, 2021). According to available data, when sprayed with different types of entomopathogenic mushrooms of the bumblebee B. terrestris and the honey bee A. mellifera, the fungus A. lecanii, which is the active ingredient of this biological product, had the lowest negative effect of all of them (Akkoç et al, 2019;Erler et al, 2022). According to literature data, the preparation Verticillin M based on the fungus A. lecanii was slightly toxic for the predatory diptera Aphidoletes aphidimyza (Rondani, 1848) used in a biometode against aphids-37.5% on day 3 and 57.5% on day 6 (Mitina et al, 2018).…”

“…Since some of them can affect various types of arthropods, including useful ones, it is necessary to conduct a preliminary assessment of their effect on the beneficial entomofauna of agrobiocenosis. In world practice, the assessment of the impact of widely used biological preparations on pollinators and entomophagous insects, and the possibility of their joint use in the production of organic products has been repeatedly highlighted in the works of researchers from around the world and continues to be relevant (Mahefarisoa et al, 2021;Presa-Parra et al, 2021;Erler et al, 2022). Currently, in Kazakhstan, the List of pesticides allowed for use on the territory of the Republic of Kazakhstan (State Inspection Committee in the Agroindustrial complex, 2020) includes 21 names of biological preparations, of which only 8 have been registered against pests of apple trees and green spaces.…”

Currently, Kazakhstan is actively researching the greening of the protection of apple orchards from lepidopteran pests. In this regard, biological preparations of various origins were tested. The aim was to study their impact on useful non-target arachno entomofauna (entomophagous insects and pollinators). During the research, both classical methods used in entomology and plant protection, and original modifications were used. In the south-east of Kazakhstan, in the agrobiocenosis of an apple orchard, an assessment of the effects of biological preparations was carried out: Phytoverm ® K.E. (aversectin C, a natural mixture of four avermectins B1a, A1a, A2a, B2a, produced by Streptomyces avermitilis microorganisms), Greene Gold, 0.3% by weight (admiration), Entolek Planteco K ® (Akanthomyces lecanii), and Lepidocide ® S.K. (Bacillus thuringiensis var. kurstaki) on entomophagous insects of harmful lepidoptera and pollinators. The greatest decrease in the number of indicator species was observed in the variants with azadirachtin and avermectin. It is concluded that when these bioinsecticides are used together with entomophagous insects and pollinators, it is necessary to draw up and apply special step-by-step schemes with a time interval between the treatment with a biological product and the release of entomophagous insects or pollinators in summer. It is also desirable to study these drugs in more detail in terms of their prolonged action, not only on entomophagous insects and pollinators but also on soilforming agents, in the conditions of Kazakhstan. Biological preparations based on Bacillus thuringiensis and Akanthomyces lecanii had almost no negative effect on the number of entomophagous insects and pollinators. When choosing biologics for use against harmful lepidoptera in apple orchards in the south-east of Kazakhstan, it is advisable to focus on these bioinsecticides as having a more sparing effect for non-target arachno entomofauna.

“…However, other families of chemical compounds (such as carbamates, organophosphates, and pyrethroids) are well known to be dangerous for these insects [ 27 , 33 , 34 ]. Conversely, there is less information on the toxicity of insecticides of biological origin for bees [ 35 , 36 , 37 , 38 , 39 ].…”

Are Botanical Biopesticides Safe for Bees (Hymenoptera, Apoidea)?

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.

To avoid potential adverse side effects of chemical plant protection products, microbial pest control products (MPCP) are commonly applied as biological alternatives. This study aimed to evaluate the biosafety of a MPCP with the active organism Bacillus thuringiensis ssp. aizawai (strain: ABTS-1857). An in-hive feeding experiment was performed under field-realistic conditions to examine the effect of B. thuringiensis (B. t.) on brood development and the bacterial abundance of the core gut microbiome (Bifidobacterium asteroids, Gilliamella apicola, the group of Lactobacillus and Snodgrasella alvi) in Apis mellifera worker bees. We detected a higher brood termination rate and a non-successful development into worker bees of treated colonies compared to those of the controls. For the gut microbiome, all tested core members showed a significantly lower normalized abundance in bees of the treated colonies than in those of the controls; thus, a general response of the gut microbiome may be assumed. Consequently, colony exposure to B. t. strain ABTS-1857 had a negative effect on brood development under field-realistic conditions and caused dysbiosis of the gut microbiome. Further studies with B. t.–based products, after field-realistic application in bee attractive crops, are needed to evaluate the potential risk of these MPCPs on honey bees.
