The aim of the present study was to investigate the effects of bee pollination of buckwheat crops on the seed productivity and plant development. Six plots each 4 m2 in size were arranged in a buckwheat field. Four plots in the field were isolated by a net. Nucs with bees were placed in two of the plots (one per plot). Plant productivity, height of plants and number of branches per marked plant...
With more than 80% of flowering plant species specialized for animal pollination, understanding how wild pollinators utilize resources across environments can encourage efficient planting and maintenance strategies to maximize pollination and establish resilience in the face of environmental change. A fundamental question is how generalist pollinators recognize "flower objects" in vastly differ...
The abundance, foraging behavior, and diurnal seasonal dynamics of the pollinator insects in chili ecosystem, impact on production was studied at Bangabandhu Sheikh Mujibur Rahman Agricultural University, (BSMRAU) Gazipur, Bangladesh using variety BARI Morich 2. crop cultivated natural, supplemented insect selfpollination conditions. lime butterfly, honey bee, carpenter bee sweat were found eco...
Hedgerow fruits provide a food resource for several UK farmland bird species from late summer, through winter and into spring. This project aims to develop the understanding of the interactions between fruit-bearing hedgerow flowers, their pollinators, hedgerow fruits and frugivorous birds. Experiments revealed that flowers of blackthorn, hawthorn and ivy all benefited from insect visits in ord...
Influence of some insecticides on the abundance and foraging activates of broad bean bee pollinators
Insect pollinators provide many essential ecosystem services including pollination, and others. However, pollinating insects are currently facing potential threats on an unprecedented scale with species decline. Honeybee Apis mellifera comprise nearly 68% of those affected insect pollinators. Irrational Insecticides application, special reference to neonicotinoides group is one the main causes ...
Agricultural Policies Exacerbate Honeybee Pollination Service Supply-Demand Mismatches Across Europe
Declines in insect pollinators across Europe have raised concerns about the supply of pollination services to agriculture. Simultaneously, EU agricultural and biofuel policies have encouraged substantial growth in the cultivated area of insect pollinated crops across the continent. Using data from 41 European countries, this study demonstrates that the recommended number of honeybees required t...
Wild and managed bees are well documented as effective pollinators of global crops of economic importance. However, the contributions by pollinators other than bees have been little explored despite their potential to contribute to crop production and stability in the face of environmental change. Non-bee pollinators include flies, beetles, moths, butterflies, wasps, ants, birds, and bats, amon...
Honeybees play an important ecological role as pollinators of many plant species, and their products are the basis for a multi-million dollar commercial industry around the world. They are major agricultural pollinators around the world and are keystone pollinators in tropical ecosystems. Pollination has been considered a keystone process to ecosystem function through the facilitation of both p...
