The most evolved plant species or Angiospermae have a specialized reproductive apparatus, with the capacity to generate pollen granules that after their physiological maturation are transferred from the male reproductive organ to female structures (androceo) (gynoecium).

The transfer described above is carried out by pollinating agents, mainly insects, including bees, which have a certain potential to detect variations in flower color and encode this signal and biologically associate it with a greater availability of carbohydrates.
It should be noted that the flowers that plants present are their reproductive structures, and these can exhibit different types of coloration polymorphism, mainly as a strategy to attract pollinating insects, and in other cases, these color changes may be related to the loss of pigments.

Now, in addition to changes associated with the loss of pigments, there are other factors such as edaphoclimatic contamination that influence the final color reflected in the floral units, which in turn leads to a decrease in the visit of pollinating agents and consequently a decrease at the reproductive level, as a result of climate change, which has become the main enemy of bees and pollinating insects.
In an attempt to reverse the reproductive decline that currently exists in agricultural fields, science has been developing sophisticated "Pollinator Drones", which according to in situ tests have shown a 90% efficiency compared to the natural procedure, although it has been inferred that it does not work on rainy or windy days.

This type of impact technologies for agricultural activity is nothing new, since the development of new applications seems unlimited when it comes to generating options to increase food production, which once again arise from the inventiveness of biological science in conjunction with disruptive technology.
