Organic farming and annual flower strips reduce parasite prevalence in honeybees and boost colony growth in agricultural landscapes

Journal of Applied Ecology, Journal Year: 2024, Volume and Issue: 61(9), P. 2146 - 2156

Published: Aug. 20, 2024

Abstract Despite the major role that insect pollinators play in crop production, agricultural intensification drives them into decline. Various conservation measures have been developed to mitigate negative effects of agriculture on pollinators. In a novel comparison efficacy three honeybee colony growth, we monitored experimental colonies 16 landscapes comprised orthogonal gradients organic agriculture, annual flower strips and perennial semi‐natural habitats. Using structural equation modelling, assessed prevalence 11 parasites, Varroa destructor loads their collective impact growth.

In light of pollinator decline, plant species suitable for the restoration and conservation pollinators need to be selected. this systemic review, we concentrated on importance NFWV (non-forest woody vegetation, i.e., linear or grouped trees/shrubs) across agricultural landscapes. temperate climate zone, flowering trees shrubs provide nectar sugar (energy) pollen (nutrients) managed wild pollinators. They also create nesting niches serve as host plants that support full life cycle The creation woodland strips/groups is a cost-effective time-saving strategy improve self-repeatable resources landscape scale. spatial distribution can help an entire network pollinator-friendly habitats. continuity food outside crop season, during seasonal bottlenecks. This concept offers other environmental benefits (e.g., water air quality improvement, mitigation). However, future work should address usefulness trees/shrubs different crops regions develop flower-rich corridors. Likewise, more advanced detailed studies are necessary determine qualitative characteristics pollen, which may result in optimization nutrition.

It is becoming increasingly accepted that beekeeping declining due to the damaging effect of global changes such as climate and land-use change directly indirectly impact Apis Melliferas. Despite numerous investigations, a comprehensive study incorporates both local knowledge has yet be conducted. For long time, researchers have suggested expert should taken into account when creating decision support tools for managing activities related natural resources, beekeeping. Unlike previous studies, this research seeks tackle these questions while also introducing concept ecosystem service in modelling, offering fresh perspective on sustainable land use. To achieve goal, we combined several methods, including using literature knowledge, beekeeper multi-source geospatial data. These data are employed hierarchical fuzzy inference system unified way. The proposed approach was applied Québec region technique appears reliable effective. validation step revealed landscape variable, particularly area used agriculture or grassland, had greatest hive weight throughout season. In addition, demonstrated meteorological factors rainfall relative humidity strongly correlated We showed access can critical factor decision-making industry, thus suggest wild-bees conservationists, decision-makers, farmers, beekeepers, other stakeholders adopt collaborative approach.

ABSTRACT The achira crop ( Canna indica ) is an ancestral symbol of the department Huila. According to Regional Information System (SIR) Governor's Office Huila, area planted annually with in for 2020 was 82.3 ha, and local demand starch (400 tons/year) imported from other departments (Cundinamarca Nariño). Beyond its economic potential, contributes ecosystem services. Its organic management, limited cultural practices, helps mitigate pollinator population decline, particularly among wild bees. problems caused by growth areas coffee conventionally managed crops make it crucial better understand relationship between biodiversity agricultural production; therefore, imperative develop sustainable management strategies that promote conservation floral visitors, pollinators, general.

Abstract In temperate climates, winter can be an arduous time for eusocial insects. Survival of honeybee colonies during depends on a delicate balance between hive thermoregulation, managing the food reserves and timing onset new worker bee generation. Winter survival is influenced by several factors, most notably colony size, Varroa mite infestation levels availability stored food. Importantly, climatic conditions floral resources previous foraging season also impact health strength before hibernation. This study, conducted across Europe, examines how landscape composition weather affect colonies. It uses pollen diversity as proxy flower resource quality available days variable to understand their causal relationships survival. We found that landscapes with higher percentages agricultural areas increased collected honeybees in autumn, whereas semi‐natural summer. Spring autumn was main driver success, emphasizing importance diverse health. While we did not find statistically significant effect survival, trends suggest potential influences, warranting further research confirm clarify role seasonal Synthesis applications : Our study highlights critical including comprehensive framework studying suggests increasing plant around apiaries implementing practices enhance significantly improve benefiting even activity, distinct from needs other pollinators.
