Method of activating entomophages and pollinators hymenoptera order natural populations with the aim of increasing the agrosystem productivity [Articol]

Abstract

Insects provide important ecosystem services of great economic value. We investigated a method for activating of entomophages and pollinators of Hymenoptera order natural populations ("field breeding"), consisting of a combination (synergy) of overseeding spice plants and placing Fabre hives nearby the fruit garden. The objects of the study were entomophages and pollinators of the Hymenoptera order. The experiment was conducted in three different biotopes: an apple orchard near a forest belt, a collection of spice plants near a pear orchard, and a field of Miscanthus sinensis. The maximum number of Megachilidae bee nests were found in artificial dark-colored shelters: made of cylindrical dark plastic (70,8%), and deltoid dark cardboard (20,8%). The bees preferred to build nests in the agrocenosis of the pear orchard nearby a plot of spice plants (91,7%). It has been established that the optimal strategy for the method of entomophage’s activating consists of combining a variety of different family’s spicy plants and ensuring continuous flowering (conveyor).
