To generally be best at controlling a pest, a biological control agent needs a colonizing skill which enables it to keep pace With all the spatial and temporal disruption of the habitat. Its control of your pest will also be greatest if it has temporal persistence, making sure that it could manage its populace even inside the short term absence of your focus on species, and if it is an opportunistic forager, enabling it to افضل شركة مكافحة حشرات وفئران rapidly exploit a pest populace.

The larvae of numerous hoverfly species principally feed upon greenfly, a single larva devouring as many as fifty daily, or one thousand in its life time. They also consume fruit tree spider mites and small caterpillars. Grown ups feed on nectar and pollen, which they involve for egg production.
