In recent decades, honeybee populations have declined, dramatically owing to destructive honey harvesting practices and the loss of foraging grounds nesting sites. Among them, Apis laboriosa Smith, 1871 (Hymenoptera, Apidae), an important pollinator species found in Himalayan region, holds significant economic ecological value. However, conservation efforts intraspecific taxonomic studies regarding it been rather limited, thus its full geographic range remains elusive. This study is first research A. Sichuan. Through a systematic integrating morphological feature analysis genomic data, following conclusions are drawn. Whole-genome resequencing data reveals that Sichuan population forms new monophyletic group (Bootstraps = 100). past ten thousand years, sizes four different regions China decreasing rapidly. Measures should be taken protect them across entire distribution range, especially Tibet Sichuan, due their relatively large genetic differences low intra-population diversity. Based on difference analysis, wing vein features with extremely were identified: width right forewing (FB), cubital index a/b (Ci), angle (E9), (K19). These findings expected offer valuable reference for future endeavors, particularly protecting high level differentiation.

High densities of managed honeybees (Apis mellifera) can threaten wild bees through exploitative competition, thus leading to population declines the latter. Although reviews have outlined key steps demonstrate these impacts-measuring resource overlap, changes in bee behavior, and trends-studies that comprehensively address aspects are virtually absent. We were granted access entire protected island Giannutri (2.6 km2) apiary (18 hives) located there during early phase coexistence between bees. Using as an open-air laboratory, we experimentally manipulated honeybee pressure by closing hives on selected days peak foraging period. In plants most visited pollinators, even short-term removals (11 h per day) increased nectar volume (∼60%) pollen availability (∼30%). absence honeybees, target (Anthophora dispar Bombus terrestris) became dominant insect-plant visitation network, potential apparent competition significantly decreased. Accordingly, both species intensified their activity suction time, a recognized proxy for quantity probed nectar, terrestris also shortened time searching. Transect monitoring revealed alarming ∼80% decline over 4 years, consistent with monopolization floral resources, reducing pollinators altering budget. These findings underscore risks introducing high into areas emphasize need rigorous preventive ecological assessments.
