Bees from Southern Brazil: diversity, floral visitation, and conservation

Revista Brasileira de Entomologia, Journal Year: 2025, Volume and Issue: 69(1)

Published: Jan. 1, 2025

ABSTRACT Understanding bee diversity and their relationships with plants is crucial for conserving pollination services. Here, we focused on the southern region of Brazil to: i) provide an overview based fauna inventories, ii) compile studies floral visitation in natural agricultural systems, iii) discuss threats conservation status fauna, particularly through endangered species lists., conducted a systematic review literature, retrieved 138 papers. Among 68 most were carried out Paraná, followed by Santa Catarina Rio Grande do Sul. Studies indicate richness up to 400 at regional scale (multiple localities). Of total studies, 48 involved cultivated plants, while 22 non-cultivated species. Canola was researched among 16 appearing nine papers, soybean eight articles. In case 23 plant studied, Bromeliaceae Orchidaceae as common families. We identified need increased research efforts western regions Atlantic Forest, well Cerrado Pampa biomes scarcity initiatives these areas. There significant gap our knowledge regarding neglected crops native plants. Regarding conservation, comprehensive monitoring data collection are urgently needed assess populations identify areas where actions critical.

Comparative temporal response of toxicity for the neonicotinoid clothianidin and organophosphate dimethoate insecticides in two species of solitary bee (Osmia bicornis and Osmia cornuta)

Solitary bees provide essential pollination services. Concerns for the decline of these wild bee species have led to calls their inclusion in pesticide risk assessment. differ from honey physiology and ecology this may affect how they respond exposure. Here we investigate life-time toxicity two insecticides, organophosphate dimethoate neonicotinoid clothianidin, mason species, Osmia bicornis O. cornuta using a toxicokinetic/toxicodynamic stochastic death model taken Dynamic Energy Budget (DEBtox) theory. Both showed concentration exposure duration dependent effects each chemical. LC50 values estimated parameters at 48 h were ≥ 14 fold 6 those 480 clothianidin respectively. Survival modelling indicated greater sensitivity than dimethoate, whilst females but not males, more sensitive both sexes bicornis. These differences related body size. Toxicokinetic toxicodynamic traits derived lower elimination rates higher killing that sensitivity. This study shows near testing is possible solitary combining adult tests with provides mechanistic understanding species.

Relative impacts of Varroa destructor (Mesostigmata:Varroidae) infestation and pesticide exposure on honey bee colony health and survival in a high-intensity corn and soybean producing region in northern Iowa

Journal of Insect Science, Journal Year: 2024, Volume and Issue: 24(3)

Abstract The negative effects of Varroa and pesticides on colony health survival are among the most important concerns to beekeepers. To compare relative contribution Varroa, pesticides, interactions between them honey bee performance survival, a 2-year longitudinal study was performed in corn soybean growing areas Iowa. infestation pesticide content stored pollen were measured from 3 apiaries across gradient production compared measurements survival.

Insect Flight: State of the Field and Future Directions

Integrative and Comparative Biology, Journal Year: 2024, Volume and Issue: 64(2), P. 533 - 555

The evolution of flight in an early winged insect ancestral lineage is recognized as a key adaptation explaining the unparalleled success and diversification insects. Subsequent transitions modifications to machinery, including secondary reductions losses, also play central role shaping impacts insects on broadscale geographic ecological processes patterns present future. Given importance flight, there has been centuries-long history research debate evolutionary origins biological mechanisms flight. Here, we revisit this from interdisciplinary perspective, discussing recent discoveries regarding developmental origins, physiology, biomechanics, neurobiology sensory control diverse set models. We identify major outstanding questions yet be addressed provide recommendations for overcoming current methodological challenges faced when studying which will allow field continue move forward new exciting directions. By integrating mechanistic work into contexts, hope that synthesis promotes stimulates efforts necessary close many existing gaps about causes consequences evolution.

A novel pesticide has lethal consequences for an important pollinator

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 952, P. 175935 - 175935

Published: Aug. 30, 2024

Wild bees pollinate crops and wildflowers where they are frequently exposed to pesticides. Neonicotinoids the most commonly used insecticide globally, but restrictions on their use rising pest resistance have increased demand for alternative Flupyradifurone is a novel that has been licenced globally bee-visited crops. Here, in semi-field experiment, we solitary (Osmia lignaria) commercial pesticide formulation (Sivanto Prime) containing flupyradifurone at label-recommended rates. We originally designed experiment examine sublethal effects, contrary our expectations, 100 % of released into pesticide-treated cages died within 3 days exposure, compared 0 control plots. Bees few after initial application survived endured prolonged including lower nesting success, impairment foraging efficiency, higher mortality. These results demonstrate exposure this poses significant threats add growing body evidence indicating can negative impacts wild field-realistic concentrations. In short-term, recommend formulations should be restricted non-flowering while reassessment its safety conducted. long-term, environmental risk assessors continue develop assessments truly holistic incorporate ecological life history traits multiple pollinator species.
