Read more about the conclusions on «Nematodes for off-season control of the Mediterranean Fruit-fly» 4th webinar in the frame of the FF-IPM project by Dr. Arne Peters that took place on 6/6/2023!
Summarised the key takeaways:
Entomopathogenic nematodes are proven to be a highly effective tool for off-season control of medflies. This promising finding offers great potential for managing these fruit pests.
Both laboratory and field experiments have shown an impressive reduction of approximately 60% in fly emergence. This demonstrates the significant impact of nematode application on medfly populations. Timing is crucial. The application of nematodes in spring or autumn is particularly favorable, considering factors such as soil moisture and temperature. This strategic approach enhances the effectiveness of the treatment.
It’s important to note that many published studies on medfly control have focused on local nematode isolates rather than commercially available isolates. This highlights the need for further research and exploration of
different nematode strains. Interestingly, the larvae inside fruits can also be infected by the nematodes, indicating their potential to target medfly populations at various life stages and to actively find them in cryptic habitats.
However, it’s worth noting that there was no infection observed during the pupal stage. This insight helps us to refine our control strategies. In the winter, medflies have a prolonged larval stage inside fruits which favors the efficacy of nematodes when applied off-season. The application method using nematodes has demonstrated robustness and consistent results, irrespective of whether it is implemented in spring or autumn. This reliability further strengthens the case for incorporating nematode-based approaches into medfly management programs.
These findings are significant steps forward in our mission to develop effective and sustainable methods for preventing and managing medfly infestations. By harnessing the power of nematodes, we can contribute to the protection of crops and the preservation of fruit yield.
