Alternative metoder til kontrol af bladlus

Conclusion

The trials demonstrate a positive effect of flower strips on natural enemies, the effect on pests appears to be more elusive, due to the complex dynamics between predators and herbivores. However, the effect on natural enemies is valuable, as shown by their contribution to predation on the two aphids, stressing the need for promoting and monitoring these predators. Digital solutions in the form of LED photonic flight sensors show promise for assessing the biodiversity effects of conservation biological control, however they should be supplemented with traditional methods for additional cross-validation.
