The role of bees in agriculture today


bees
Agriculture is the first true beneficiary of the services provided by bees. His contribution in economic terms is really significant to the extent that direct income from beekeeping (honey, wax, pollen and other products) goes to a second term was attempted to estimate this regard in many countries, so for example :

In the United States reflects a ratio of 100 to 1000 times greater benefits to agriculture and direct income hive products.

In Italy you can also consider the importance of bees as pollinators is 60 times greater than the benefits produced by bee products (Giordani 1978).

And in this same country, a pollination experiment kiwi plants in large areas, showed that the honeybee was the insect visitor kiwi flowers and therefore more pollinator, increasing production because the production of fruits large size is required a considerable contribution of pollen from the male flowers of the female to increase the number of pregnancies per flower and consequently also the number of seeds, fruits thus achieving greater than 90 grams.

In France, according to the Bulletin Technique, in 1982, totaled the economic impact of beekeeping on different agricultural crops on which they act, at 53.785 million pesetas in profit. It is reckoned that the bees involved approximately 8 - 100%, depending on the species concerned, in the yield of cultivated plants by insect pollination.

In Spain, crops pollinated by bees under are mainly fruit trees (almond, peach, cherry, plum, apple, pear) forage legumes (alfalfa, clover), cucurbits (melons, cucumbers, pumpkins, zucchini, eggplant) , plants for the extraction of oil (sunflower, rapeseed), textile fibers (flax, cotton), all horticultural crops (strawberries, raspberries, asparagus, blackberries, tomatoes), flowering plants and a newcomer, the vine, are a partial list of plants that depend necessarily or at least favored by the pollination action of bees to the point that it would be much easier to cite the vegetables do not.

It is now indisputable that the bees and beekeepers with them, to a considerable extent involved in agricultural production. Thanks to this role, the private equity beekeepers becomes public property, since the benefit derived from his work is felt throughout the community and thus establishing a reciprocal link between bees, environment, agriculture and man, to be protected.

In the Canaries there is no data, but many of the experiences cited above can be extrapolated to the types of crops on the islands such as tomato, banana, grapes, strawberries, fruit trees, including here the medlar, the avocado and especially greenhouse crops (cucumber, zucchini, cantaloupe, watermelon, etc) which are already being carried out experiments of this type with similar results to those obtained in the peninsula, so that beekeepers and farmers mutual benefit, the beekeeper by renting their hives, they do not collect or honey or pollen, and the farmer increases their yield and quality of them.

Pollination and It's Types

pollination

What is pollination?

The term refers to pollination removal or transfer of pollen from a flower that produces it, to another flower of the same species, in principle, that it receives. This phenomenon is so simple at first glance, associate brings an immediate and far-reaching, such as the formation of the fruit , of vital importance in agriculture, as we shall see and seed formation , which will help the plant to perpetuate and multiply their species.

In fact, higher plants can be multiplied also by other systems, the general from portions of the plant capable of regenerating the entire plant body, but these methods are much less important biological reproduction by seed, with its varied However, it is the last link of a long natural process that precedes it, in a series fruit-flower-seed, a direct result of pollination.

The types of pollination

Although many plants are hermaphrodites, ie they have both reproductive systems (male and female) located in the same flower, hardly ever played together (autogamy) and the pollen from one flower to another flower travels of the same species, or another similar characteristics to fertilize. This is what is known as cross-fertilization or heterogamy. This phenomenon gives the child an increased chance of survival while a different genetic makeup and variable, so that the common standard in all vegetables and especially those of agricultural interest, it is precisely this type of fertilization , which also produces better results in crop production.

PollinationIn general, there are three types of pollination: it is called anemophilous when pollen reaches the flowers carried by the wind; hydrophilic when the transport is done by the water, and finally zoophilic when run by an animal. The latter is much more frequent and effective. Within zoophilic pollination, undoubtedly the most important is entomophilous, ie, pollination by insect pollinators.

No wonder it is the most prominent, if we consider that these are the largest group within the Animal Kingdom. In addition, insects are spread throughout the land, often flying and have a size suitable for this task.

Thus, flowers and insects are the clearest example of mutualism between animal and vegetable.Thousands of years of evolution, have mutually adapted so that two great advantages achieved thereby. If the color, elegance, grace and fragrance of the flowers attract us and arouse our sensitivity, within the natural universe are not intended to represent our feelings, but to attract pollinating insects, which act as intermediaries in fertilization.
