Bumblebees are resilient to neonicotinoid-fungicide combinations

Bumblebees are among the most important wild bees for pollination of crops and securing wildflower diversity. However, their abundance diversity have been on a steady decrease in last decades. One factors leading to decline is frequent use plant protection products (PPPs) agriculture, which spread into forests natural reserves. Mixtures different PPPs pose particular threat because possible synergistic effects. While there comparatively large body studies effects honeybees, we still lack data bees. We here investigated influence fungicide Cantus® Gold (boscalid/dimoxystrobin), neonicotinoid insecticide Mospilan® (acetamiprid) combination bumblebees. Cognitive performance foraging flights bumblebees were studied. They essential provisioning survival colony. introduce novel method testing four treatments simultaneously same colony, minimizing inter-colony differences.

Investigating the effects of glyphosate on the bumblebee proteome and microbiota

Glyphosate is one of the most widely used herbicides globally. It acts by inhibiting an enzyme in aromatic amino acid synthesis pathway specific to plants and microbes, leading view that it poses no risk other organisms. However, there growing concern glyphosate associated with health effects humans ever-increasing body evidence suggests potential deleterious on animals including pollinating insects such as bees. Although pesticides have long been considered a factor decline wild bee populations, research bees has focussed demonstrating understanding insecticides. To assess whether bees, we characterised changes survival, behaviour, sucrose solution consumption, digestive tract proteome, microbiota bumblebee Bombus terrestris after chronic exposure field relevant doses technical grade or glyphosate-based formulation, RoundUp Optima+®.

Field-realistic acute exposure to glyphosate-based herbicide impairs fine-color discrimination in bumblebees

Pollinator decline is a grave challenge worldwide. One of the main culprits for this widespread use of, and pollinators' chronic exposure to, agrochemicals. Here, we examined effect field-realistic dose world's most commonly used pesticide, glyphosate-based herbicide (GBH), on bumblebee cognition. We experimentally tested (Bombus terrestris) color scent discrimination using acute GBH exposure, approximating from day's foraging in patch recently sprayed with GBH. In 10-color experiment five learning bouts, treated bumblebees' rate fell to zero by third bout, whereas control bees increased their performance last two bouts. memory test, bumblebees performed near chance level, indicating that they had lost everything learned during while were performing close level bout. However, did not affect bees' 2-color or 10-odor experiment, which suggests impact limited fine does necessarily generalize less specific tasks other modalities. These results indicate widely pesticide damages fine-color discrimination, essential pollinator's individual success colony fitness complex environments. Hence, our study sublethal poses greater threat pollination-based ecosystem services than previously thought, tests should be integrated into risk assessment.

Effects of spinetoram and glyphosate on physiological biomarkers and gut microbes in Bombus terrestris

The sublethal effects of pesticide poisoning will have significant negative impacts on the foraging and learning bees bumblebees, so it has received widespread attention. However, little is known about physiological spinetoram glyphosate exposure bumblebees. We continuously exposed Bombus terrestris to (2.5 mg/L) or under controlled conditions for 10 days. superoxide dismutase, glutathione-S-transferase, carboxylesterase, prophenoloxidase, α-amylase protease activities, changes in gut microbes were measured understand physiology Sublethal significantly increased dismutase activity decreased bumblebees but had no effect carboxylesterase activities. In addition, prophenoloxidase. Interestingly, we observed that neither two pesticides a dominant bacteria, altered structure fungal community, reduced relative abundance Zygosaccharomyces associated with fat accumulation. These results suggest do not affect detoxification system may bumblebee health by inhibiting energy acquisition. Our provide information low concentrations terms microbes.
