“…The third important finding of our study is that the acute toxicity of spray applications aimed to completely cover the plantation with Acttra/ Entrust can be as high as that observed for Entrust and Exalt formulations at the recommended field dose. Given that several studies have shown spinosyns to be highly toxic to A. mellifera, even similar to neonicotinoids, in oral and topical tests (Gómez-Escobar et al, 2018;Miles, 2003;Padilha et al, 2020;Stanley et al, 2015), it was not surprising to observe such high mortality when honeybees were experimentally covered by each spinosad treatment by directly aiming the spray on them. This, nonetheless, would be the worst-case scenario.…”

Crop protection substances are continuously developed to prevent the decimation of non-target insect populations through insecticide use. The bait formulation Acttra SWD was created to attract the adult spotted-wing drosophila, a generalist pest of berries, and when mixed with insecticide would cause a reduction in the volume of insecticide applied, thus avoiding a complete coverage of crops and resulting in economic and ecological benefits to society. However, Acttra SWD has some compounds, including sugars and fruit odors, that might attract non-target fauna, especially insect pollinators. Therefore this study aimed (1) to investigate if Acttra SWD mixed with the recommended pesticide, i.e. spinosad (Entrust), is attractive to the honey bee, which is extensively used for berry pollination and (2) to evaluate the insecticidal activity of Acttra/Entrust in oral and contact tests on the same species. In all replicates, most foragers rejected feeders that offered Acttra/Entrust, and some switched to Acttra/Entrust-free feeders. Accordingly, mortality caused by this mixture in oral tests was low and did not differ from control, since the majority of bees did not consume the Acttra/Entrust treatment. However, mortality caused by this mixture was higher than in control groups in topical tests. Our results indicate that honey bees will not be attracted to and poisoned by crops sprayed with Acttra/Entrust, but contact with the bait would result in lethal or sub-lethal effects.

“…The information imbalance between Apis and non-Apis bees on the toxicity of pyriproxyfen is representative of what is encountered with all the other pesticides with only few exceptions such as the neonicotinoids for which the toxicity has been evaluated on different non-Apis bee species [36,37,40,41,43,45,46,48,49,51,57,62,66,[70][71][72]74].…”

“…The studies on the toxicity of pesticides against the bumble bees are fairly abundant [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50]. On the contrary, the toxicity studies are limited on stingless bees [51][52][53][54][55][56][57]. As regards solitary bees, there are great disparities between taxa.…”

Pyriproxyfen is a juvenile hormone mimic used extensively worldwide to fight pests in agriculture and horticulture. It also has numerous applications as larvicide in vector control. The molecule disrupts metamorphosis and adult emergence in the target insects. The same types of adverse effects are expected on non-target insects. In this context, the objective of this study was to evaluate the existing information on the toxicity of pyriproxyfen on the honey bee (Apis mellifera) and non-Apis bees (bumble bees, solitary bees, and stingless bees). The goal was also to identify the gaps necessary to fill. Thus, whereas the acute and sublethal toxicity of pyriproxyfen against A. mellifera is well-documented, the information is almost lacking for the non-Apis bees. The direct and indirect routes of exposure of the non-Apis bees to pyriproxyfen also need to be identified and quantified. More generally, the impacts of pyriproxyfen on the reproductive success of the different bee species have to be evaluated as well as the potential adverse effects of its metabolites.

“…Spinosad and spinoteram (another fermentation product of Saccharopolyspora spinosa) can prove highly toxic to these bees. In particular, a considerable reduction in adult survival after exposure to spinosyns was documented for M. quadrifasciata (Barbosa et al, 2015b;Piovesan et al, 2020), Partamona helleri (Tomé et al, 2015;dos Santos Araujo et al, 2019a), Plebeia emerina (Padilha et al, 2019), Plebeia lucii (Marques et al, 2020), Scaptotrigona xanthotricha (Tomé et al, 2015), and Tetragonisca fiebrigi (Padilha et al, 2020;Piovesan et al, 2020). In addition to the lethal effect, a plethora of sublethal effects on different developmental stages were demonstrated in several studies (Figs.…”
