Large-scale agroecosystems are often a mosaic of different annual and perennial crops, semi-natural habitats, natural habitats within various land-use systems. In these systems, pest beneficial insect population patterns increase decline at varying degrees across crops. Different biotic abiotic interactions systems influence patterns, such as landscape configurations, climatic conditions, on-farm practices. Pollination by insects is critical ecosystem service necessary to produce most including those providing essential nutrients for food security. When managed appropriately, agricultural landscapes can provide habitat many species.

Consequently, pollinator conservation strategies potentially overlook balance juvenile diets. I studied a representative bee, Osmia bicornis, explore contributions various nutritional quality diet.

Honey bees (Apis mellifera) are important pollinators for natural and cultivated species. Due to their high sensitivity stressors, they also valuable indicators of environmental changes agricultural management practices. In this study, we compared the performance incidence pesticides over sentinel hives within forest remnants with those linear fragments (LFF) surrounded by soybean fields under conventional management. Sentinel in LFF showed some signs deterioration, such as colony collapse, low numbers brood frames, pesticide occurrences, but honey production number adult were similar forest. Soybean pollen was scarce absent bee bread, suggesting that may be relying more on wild plant We detected 5 (azoxystrobin, carbendazim, chlorpyrifos, imidacloprid, coumaphos) both at forests pollen, bodies, wax; old (2 yr exposition management).

Agricultural landscapes often provide an impoverished environment for bees given their limited plant and pollen diversity. Agri-environment schemes (AES) such as flower strips have been developed to improve the quality of agricultural but efficacy varies with composition and, specific pollinators, value available species. This study provides a detailed report collection patterns two bee species, western honeybee ( Apis mellifera L.) common eastern bumble Bombus impatiens Cresson), over foraging season.

Sunflower, Helianthus annuus L., is a prominent global oilseed crop with rising cultivation and appeal as bee-friendly plant by providing abundant floral resources for pollinators. Mass-flowering crops can increase the availability of resources, sunflower good opportunity to relieve pollen scarcity during late summer in agricultural landscapes. Yet this should be taken caution they also provide homogeneous source nutrition. This study aimed review summarize nutritional profile pollen, nectar, bee bread, honey, while assessing their effects on survival, development, health. Furthermore, we present here general state knowledge additional pollinator syndromes that extend beyond including those influencing visual olfactory attraction. We found pollen’s quality questioned due lower protein amino acid deficiencies, its nutrient content, like nectar sugars, had large variability. Sunflower consumption showed mixed Apis mellifera Bombus species, sometimes negatively impacting development survival.

Pollination services are crucial for maintaining ecological stability and ensuring food security humans. Managed honey bees, which economically valuable experiencing population growth due to the increasing demand their products, play a significant role in pollination. To produce high-quality honey, beekeepers often choose natural high meadows, characterized by plant species richness, apiaries. This practice, turn, may contribute pollination of native plants, as managed bees likely forage on diverse floral resources within these meadows In this study, we investigated nutritional position plants Iran using melissopalynology method determine extent contribution plants. Ninety-four samples were collected from located pastures two biodiversity hotspots (Zagros Alborz). Then, pollens extracted photographed scanning electron microscopy. next step, identified, abundance was calculated. The results showed that visited 54 genera, seven non-native Additionally, more highest pollen observed at altitudes ranging 1000 3000 m. Therefore, set up hives altitude range obtain honey. general, melissopalynological analysis, involving identification genera counts, revealed contributed less than 3% Iran.
