Abstract Honey bees ( Apis mellifera ) are one of the most crucial pollinators, providing vital ecosystem services. Their development and functioning depend on essential nutrients substances found in environment. While collecting nectar as a carbohydrate source, routinely encounter low doses ethanol from yeast fermentation. Yet, effects repeated exposure bees’ survival physiology remain poorly understood. Here, we investigate impacts constant occasional consumption food spiked with 1% honey bee mortality alcohol dehydrogenase (ADH) activity. This concentration might be tentatively judged close to that natural conditions. We conducted an experiment which were exposed three types long-term diets: sugar solution (control group simulated conditions no access ethanol), every third day (that occasional, infrequent ethanol) daily (simulating constant, routine ethanol). The results revealed both increased bees, but only after several days. These rates rose frequency intake. ADH activity remained similar all groups. Our findings indicate carries harmful accumulate over time. Further research is needed pinpoint exact ingested

Abstract Several factors, including environmental degradation, air pollution, intense urbanization, excessive agriculture, and climate change, endanger the well-being of animals plants. One major issues with an increasingly negative impact is agricultural contamination pesticides antibiotics. Seed coatings neonicotinoid insecticides used as a protective layer against pests are shown to exceed permissible limits in most cases. Neonicotinoid compounds bind nicotinic acetylcholine receptors, therefore affecting honey bees’ brain. Heavy metals higher concentrations lethal for bees, residue bee products might pose threat human health. Highly effective acaricides treat Varroa destructor infestations colonies have effects on reproduction, olfaction, production. Furthermore, amitraz fluvalinate mostly found highest amounts lead decreased production reduced colony along learning ability memory. However, scientific studies that bees act reliable bio-indicator pollution. In response growing demand products, adulteration improper storage conditions gotten worse represent new risk factor. light shifting global economy, it important analyze consumer expectations adjust manufacturing accordingly. By ensuring manufacture high-quality, traceable devoid drug residues, consumers will be better protected from subsequent health problems. This review’s objectives based necessity identifying risks associated products. Graphical abstract

In this comprehensive exploration, we delve into the pivotal role of host plants in shaping intricate interactions between herbivorous insects and their pathogens. Recent decades have seen a surge studies that demonstrate are crucial drivers pathogens, providing novel insights direct indirect shape tri-trophic interactions. These built on wide range from viruses to bacteria, protozoans fungi. We summarise these studies, discuss mechanisms plant-mediated insect resistance infection, ranging toxicity plant chemicals pathogens enhancement anti-pathogen immune responses, modulation insect's microbiome. Although provide evidence for roles all mechanisms, also point out majority existing phenomenological, describing patterns without addressing underlying mechanisms. To further our understanding interactions, therefore urge researchers design enable them specifically distinguish by which affect susceptibility

Microbes shape the health of bumblebees, an important group pollinators, including species conservation concern. Most microbial research on bumblebees has focused eukaryotic and viral pathogens or core gut microbiome, a community host-specialized bacterial symbionts that helps protect hosts against pathogens. Bumblebees also harbour third class microbes: non-core bacteria, which are non-host specific vary among individuals. Understanding their functional role how they interact with is for bumblebee ecology management. We surveyed bacteria in wild workers (Bombus impatiens) conducted laboratory experiments gnotobiotic B. impatiens to examine factors shaping colonization by focal bacterium (Serratia marcescens) its consequences bee health. Non-core Serratia, frequently occur at high abundance roughly half individuals harbouring least 10% bacteria. Experiments showed Serratia marcescens better colonizes when bees inoculated early (within 1 day adult emergence) microbiome disrupted. A mixed wildflower pollen diet facilitated highest level infection compared two monofloral treatments. provide evidence pathogenic: exposing disrupted microbiomes strongly reduced lifespan and, as result, total reproduction. These results have three implications: first, widespread some opportunistic Second, plays crucial protecting these Third, timing inoculation relative age, well diet, key factor controlling pathogen gut. Overall, findings suggest could be target monitoring managing
