“…1). Several studies have shown that vegetative buffers that provide ecological benefits such as nectar and pollen can improve the reproductive success of natural enemies and that this may lead to lower abundance of pest arthropods in the crop plants (Coll 2009;Gurr et al 2005;Heimpel and Jervis 2005).…”

The influence of weedy field strips on the abundance patterns of western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), and predatory bugs of Orius spp. (Hemiptera: Anthocoridae), on faba bean and on weeds was investigated in Adana province, Turkey, during 2005-2006. There were two treatments: in one treatment, weeds at the margins and inside the plots were regularly controlled by tillage; in the other treatment no weed control was done. Thrips and Orius were sampled by beating faba bean plants and weeds. Orius niger (Wolff) was the most abundant predatory insect species in faba bean and flowering weeds, with numbers of adults and nymphs significantly greater in plots with weedy margins than in weed-free plots. Flowering weeds did not contribute to the abundance of F. occidentalis on faba bean. Abundance of adults of Orius spp. did not coincide with the abundance of F. occidentalis on faba bean or weeds. There were significant negative associations for numbers of Orius spp. among faba bean and the weed species Lamium amplexicaule L. or Sinapis arvensis L. (P<0.05), indicating movement of Orius individuals from the weeds to faba bean during March-April. Finally, faba bean and weeds may provide some benefits to predators, such as nectar, pollen, shelter and egglaying sites rather than as sources of insect prey. Cultivation of faba bean could be useful for conservation and augmentation of beneficial insects, including Orius spp. Furthermore, field margins bearing flowering weeds such as S. arvensis and L amplexicaule should be protected against destructive management practices, because they host considerable numbers of the Orius species.

“…2007 ). In complex landscapes, natural enemies and pollinators move among natural and semi-natural habitats that provide them with refugia and resources that may be scarce in crop fields ( Coll 2009 ). Natural enemies with the ability to disperse long distances or that have large home ranges are better able to survive in disturbed agricultural landscapes with fewer or more distant patches of natural habitat ( Tscharntke et al .…”

Agricultural ecosystems provide humans with food, forage, bioenergy and pharmaceuticals and are essential to human wellbeing. These systems rely on ecosystem services provided by natural ecosystems, including pollination, biological pest control, maintenance of soil structure and fertility, nutrient cycling and hydrological services. Preliminary assessments indicate that the value of these ecosystem services to agriculture is enormous and often underappreciated. Agroecosystems also produce a variety of ecosystem services, such as regulation of soil and water quality, carbon sequestration, support for biodiversity and cultural services. Depending on management practices, agriculture can also be the source of numerous disservices, including loss of wildlife habitat, nutrient runoff, sedimentation of waterways, greenhouse gas emissions, and pesticide poisoning of humans and non-target species. The tradeoffs that may occur between provisioning services and other ecosystem services and disservices should be evaluated in terms of spatial scale, temporal scale and reversibility. As more effective methods for valuing ecosystem services become available, the potential for ‘win–win’ scenarios increases. Under all scenarios, appropriate agricultural management practices are critical to realizing the benefits of ecosystem services and reducing disservices from agricultural activities.

“…Agroecosystems are abundant sources of mass flowering and may serve as a food support system for bees at a particular time of the year. Thus, numerous bees utilize both natural and human-managed ecosystems such as cropland to suffice their nutritional, sheltering and their reproduction requirements [22,41,43,44,88]. We sampled the bees in the peak flowering period in Doon valley.…”

“…Studies on semi-natural habitats have shown to differentially support bee populations in agricultural landscapes [39, 40]. Pollinators’ utilize forest and agrarian habitats for resources such as forage and nesting [22, 41–44]. Monoculture reduces not only natural areas [45] in and around farms but also the floral diversity [38].…”

52Tropical regions are subjected to rapid land use changes altering species 53 composition and diversity in communities. The non-Apis bees are vital invertebrates 54 continued to be highly neglected in the tropics. We compared their diversity status, 55 richness and composition across natural areas and agroecosystems in Doon valley, a 56 subtropical-temperate landscape situated at the foothills of outer Himalayas in India. We 57 investigated how two major habitats relate to non-Apis bee diversity, specifically seeking 58 answers to (1) Whether natural habitat is a refuge to richer and rarer bee communities 59 than agroecosystems? (2) Are natural habitats important for supporting wild bee 60 populations in agroecosystems? (3) Do polyculture farms behave similar to natural 61 habitats and therefore support richer bee communities than monoculture? Observation and 62 pantrap sampling were used to collect data. We recorded 43 species belonging to bees of 63 five families. The findings of our investigation demonstrate the importance of natural 64 habitats as a potential refuge for non-Apis bees. The findings highlighted that Doon valley 65 harboured twenty-five rare species of non-Apis bees, and natural habitats are a refuge to 66 11 rare specialist species (clamtest; Specialization threshold K = 2/3, Alpha level = 67 0.005). Natural habitat diversity in Doon valley supports bee communities in nearby 68 agroecosystems (R2 = 0.782, SE = 0.148, P = 0.004). Polyculture practices in 69 agroecosystems (<100m from forest H' = 2.15; >100m from forest = 2.08) in the valley 70 mimic natural habitats (H' = 2.37) and support diverse non-Apis bee communities (2.08) 71 in comparison to monocultures (<100m from forest H' = 2.13; >100m from forest =1.56). 72Bees evolved with flowering plants over 120 million years and they suffice an ever-73 growing anthropogenic nutrition needs with their services through enhanced agricultural 74 production in pursuit of forage. We finally recommend similar assessments of bee 75 diversity and plants they support in different habitats and vice versa. 77Pollinators have a crucial role to play in pollination, a key ecological service, that 78 enhances plant production [1,2]. Bees, in particular, are considered the prime pollinator 79 group [3,4]. Beekeeping has hence become an indispensable part of farming cultures 80 worldwide. Managed honey bees successfully pollinate and are responsible for the 81 production of seeds and fruits of about 75% of the most commonly consumed food crops 82 worldwide [5] and an unknown number of wild plants globally [1,2,5]. In addition to the 83 managed honey bees, pollination by the native wild bees is an indiscernible but 84 imperative process to the ecosystem. Native wild bees (non-Apis) other than honey bees 85 (Apis) are increasingly finding the center stage in the backdrop of the global decline of 86 the managed bees [6,7]. Over the last half a decade the honey bee populations suffered a 87 massive decline globally, predominantly in North America [8,9] and a Eu...
