The European honeybee (Apis mellifera) is a highly abundant introduced pollinator with widely established feral populations across large proportion of Australia. Both managed and contribute significantly to the pollination many native plant species but have also disrupted plant-pollinator dynamics. Varroa mite (Varroa destructor), parasite associated collapse or unmanaged globally, has recently become in Australia will inevitably spread country. If decline significantly, there may be range effects on Australian species, including dynamics seed set. This would potential implications for risks faced by particularly those already threatened. However, exact honeybees plants are uncertain as role ecosystems poorly understood. We identify consequences varroa highlight knowledge gaps that currently limit our understanding subsequent impacts flora.

0Pollination crisis Down‐Under: Has Australasia dodged the bullet?
Ecology and Evolution, Journal Year: 2023, Volume and Issue: 13(11)
Published: Oct. 30, 2023
Abstract Since mid‐1990s, concerns have increased about a human‐induced “pollination crisis.” Threats been identified to animals that act as plant pollinators, plants pollinated by these animals, and consequently human well‐being. Threatening processes include loss of natural habitat, climate change, pesticide use, pathogen spread, introduced species. However, concern has mostly during last 10–15 years from Europe North America, with Australasia, known Down‐Under, receiving little attention. So perhaps Australasia “dodged the bullet”? We systematically reviewed published literature relating crisis” via Web Science, focusing on issues amenable this approach. Across issues, we found steep increase in publications over few decades major geographic bias towards relatively attention Australasia. While are underrepresented, factors responsible elsewhere for causing commonly occur so lack coverage probably reflects awareness rather than absence problem. In other words, not bullet” should take immediate action address mitigate its own Sensible steps would taxonomic work suspected protection pollinator populations threatened extinction, establishing long‐term monitoring plant–pollinator relationships, incorporating pollination into sustainable agriculture, restricting use various pesticides, adopting an Integrated Pest Pollinator Management approach, developing partnerships First Nations peoples research, conservation management their pollinators.

7Preliminary New Study Indicates Possible Dramatic Decline in the Diversity of Insects Visiting Flowers of Jarrah (Eucalyptus Marginata) in Kings Park Over 26 Years

The recent decline of terrestrial insects in many parts the world is growing concern due to fundamental ecosystem services they perform. Pollination a vital service predominantly performed by insects, with inestimable environmental and economic benefits. Accurate assessment management insect pollinator declines, other impacts are hindered lack long-term monitoring data notably an absence Southern Hemisphere studies. This preliminary study aims address some these gaps determining if diversity floral visitors potential pollinators canopy tree species Jarrah (Eucalyptus marginata) within Kings Park may have changed over 26 years replicating methods employed previous research (undertaken Yates et al. 2005). Additionally, this determine relative abundance introduced European honeybee (Apis mellifera) compared native bees visiting flowers also changed. We observed at three trees across morning, midday, evening consecutive days mid-December 2023 (peak flowering). A total 3023 individual observations were made, recording 7 orders, 25 families, 39 genera, 45 species. found that abundances comparable ago but substantial shift composition 46% less documented only 25% reoccurring. Ten additional families not ago, most capable performing pollination varying efficacies. Ants had replaced as common visitor flowers, while honeybees was still significantly greater than bees, proportion declined, least time our study. should be confirmed more replicated studies Park, highlights importance monitoring, need for further avenues urban accurately assess any widespread insects. important protecting provide local global scales.

0One for all and all for one: a review on the commonality of risk to honeybees and wild pollinators and the benefits of beekeepers in conservation
Frontiers in Bee Science, Journal Year: 2024, Volume and Issue: 2
Published: March 14, 2024
Pollinator declines across the globe are centrally driven by a synergistic interaction between intensive land use, pesticides, and climate change. Competition managed wild pollinators has been growing topic of research, however ensuing social conflict builds antagonism beekeepers conservationists, two parties that have an interest in protecting natural diversity for pollinators. The threats perpetuating this potential competition as real bees species uniting both groups, wherever possible, can create long lasting meaningful change current agricultural practices. This review examines most recent literature on pollinator common drive it. It also delves into elements beekeeping to contribute protection habitats. Beekeepers genuine preserve space with their charismatic species, dutiful observations, innovative techniques, they be valuable assets filling knowledge gaps generating public interest. strategies future should include key stakeholders if impacts improved.

0Influence of Pesticide Application Method, Timing, and Rate on Contamination of Nectar with Systemic and Nonsystemic Pesticides
Environmental Toxicology and Chemistry, Journal Year: 2024, Volume and Issue: 43(12), P. 2616 - 2627

Abstract Exposure to pesticides is one potential factor contributing the recent loss of pollinators and pollinator diversity. Few studies have specifically focused on relationship between pesticide management during ornamental plant production contamination nectar. We evaluated nectar in Salvia ‘Indigo Spires’ (Salvia longispicata M. Martens & Galeotti × S. farinacea Benth.) associated with applications systemic insecticide thiamethoxam, nonsystemic fungicides boscalid pyraclostrobin. Applications were made at labeled rates for commercially available products, we compared influence application method (drench vs. spray), timing (relative flowering), rate (low high) each pesticide. Nectar was sampled using 50-µL microcapillary tubes analyzed by liquid chromatography–tandem mass spectrometry. The results indicate that concentrations from spray resulted least lower occurring when thiamethoxam applied before blooming lowest rate. Concentrations its metabolite clothianidin detected all treatments (regardless method, timing, or application), ranged 3.6 ± 0.5 ng/mL (spray-applied blooming, low rate) 1720.0 80.9 (drench-applied after high rate). Residues below quantification limits 81.2 4.6 Drench highest levels exceeded published median lethal (LC50s/median doses native bees and/or honeybees cases). Spray exceeding LC50s some bee species. In comparison, much than no-observable-effect sublethal toxicity values, indicating risks toxicity. Environ Toxicol Chem 2024;43:2616–2627. © 2024 SETAC
