Abstract :
[en] Neonicotinoid-based real control of aphids in sugar beet permitted the effective management of associated phytoviruses. However, the prohibition on their usage has prompted an urgent search for viable replacements. The development of sugar beet varieties with aphid and/or virus resistance and/or tolerance has a huge potential to reduce aphids and the harm caused by transmitted viruses. Semiochemicals also play a significant part in determining intra- and inter-specific interactions, which directly affect aphid fitness, feeding activity, and ultimately their capacity to spread viruses. Another method of aphid management involves the use of plant volatile organic compounds (VOCs) in conjunction with an attract and kill strategy. Entomopathogenic fungi could also be used to manage aphids without endangering helpful entomofauna. Finally, soil bacteria are particularly effective biocontrol agents because they induce systemic resistance (ISR) as plant growth promoting rhizobacteria (PGPR). The sugar beet-aphid virus model would be a perfect place to test these microbial players. The adoption of complementing eco-compatible techniques in the sugar beet crop will be ensured by the application of a variety of biocontrol opportunities connected to creative aphid control strategies. This should make it possible to create technical itineraries for a comprehensive approach to controlling aphids and related viruses depending on the situation.
