This is a list of crop plants pollinated by bees along with how much crop yield is improved by bee pollination. [1] Most of them are pollinated in whole or part by honey bees and by the crop's natural pollinators such as bumblebees, orchard bees, squash bees, and solitary bees. Where the same plants have non-bee pollinators such as birds or ...
Dry pollen, is a food source for bees, which may contain 16–30% protein, 1–10% fat, 1–7% starch, many vitamins, some micro nutrients, and possibly a little sugar. The protein source needed for rearing one worker bee from larval to adult stage requires approximately 120 to 145 mg of pollen.
However, a few plants whose pollen contains toxic substances (e.g., Toxicoscordion and related genera in the Melanthieae) are visited by oligolectic bees, and these may fall into the former category. The evidence from large-scale phylogenetic analyses of bee evolution suggests that, for most groups of bees, oligolecty is the ancestral condition ...
This leads to shifts in pollination syndromes and to some genera having a high diversity of pollination syndromes among species, suggesting that pollinators are a primary selective force driving diversity and speciation. [5] [6] Ophrys apifera is an orchid species that has a highly evolved plant-pollinator relationship. This specific species ...
Beekeeping – bees are kept for their products (principally honey), and their utility in pollinating crops; Bees and toxic chemicals; Brood (honey bee) – the egg, larval, and pupal form of the bee and the comb in which they develop; Buckfast bee – a productive breed of bee suitable for damp and cloudy climes
Species in the genus build cells in underground nests that are lined with a cellophane-like plastic secretion, a true polyester, [2] earning them the nickname polyester bees. [ 3 ] As of 2012 [update] there were about 469 described species, and an estimated total around 700. [ 4 ]
A honey bee collecting nectar from an apricot flower.. The nectar resource in a given area depends on the kinds of flowering plants present and their blooming periods. Which kinds grow in an area depends on soil texture, soil pH, soil drainage, daily maximum and minimum temperatures, precipitation, extreme minimum winter temperature, and growing degre
A leaf-cutter bee showing abdominal scopa. Megachilidae is a cosmopolitan family of mostly solitary bees.Characteristic traits of this family are the restriction of their pollen-carrying structure (called a scopa) to the ventral surface of the abdomen (rather than mostly or exclusively on the hind legs as in other bee families), and their typically elongated labrum.
