Pollination management

Pollination management is the horticultural practices that accomplish or enhance pollination of a crop, to improve yield or quality, by understanding of the particular crop's pollination needs, and by knowledgeable management of pollenizers, pollinators, and pollination conditions. While people think first of the European honey bee when pollination comes up, in fact there are many different means of pollination management that are used, both other insects and other mechanisms. There are other insects commercially available that are more efficient, like the blue orchard bee for fruit and nut trees, local bumblebees better specialized for some other crops, hand pollination that is essential for production of hybrid seeds and some greenhouse situations, and even pollination machines. Pollinator decline With the decline of both wild and domestic pollinator populations, pollination management is becoming an increasingly important part of horticulture. Factors that cause the loss of pollinators include pesticide misuse, unprofitability of beekeeping for honey, rapid transfer of pests and diseases to new areas of the globe, urban/suburban development, changing crop patterns, clearcut logging (particularly when mixed forests are replaced by monoculture pine), clearing of hedgerows and other wild areas, bad diet because of loss of floral biodiversity, and a loss of nectar corridors for migratory pollinators. With the declining habitat and resources available to sustain bee populations, populations are declining. List of crop plants pollinated by bees The increasing size of fields and orchards (monoculture) increase the importance of pollination management. Monoculture can cause a brief period when pollinators have more food resources than they can use (but monofloral diet can reduce their immune system) while other periods of the year can bring starvation or pesticide contamination of food sources. Most nectar source and pollen source throughout the growing season to build up their numbers.

Apis mellifera

L'Abeille européenne, avette ou mouche à miel (Apis mellifera) est une abeille à miel originaire d'Europe. Elle est considérée comme semi-domestique. C'est une des abeilles élevées à grande échelle en apiculture pour produire du miel et pour la pollinisation. Le nom de genre est le terme latin signifiant « abeille », et l'épithète spécifique mellifera signifie « qui donne du miel », en référence à la tendance de l'espèce à produire une grande quantité de miel pour le stocker au printemps et en été avant consommation pendant l'hiver.

Pollenizer

A pollenizer (or polleniser), sometimes pollinizer (or polliniser, see spelling differences) is a plant that provides pollen. The word pollinator is often used when pollenizer is more precise. A pollinator is the biotic agent that moves the pollen, such as bees, moths, bats, and birds. Bees are thus often referred to as 'pollinating insects'. The verb form to pollenize is to be the source of pollen, or to be the sire of the next plant generation.
