چکیده
Wildflower strips and biodiversity-friendly management are promoted as ways of enhancing biodiversity natural pest control in agroecosystems. Their efficacy for providing resources shelters enemies has been well studied, but little is known about how wildflower strip mediated by local field landscape composition. In this study, we explored the effects floral perennial flower on faba bean aphids their antagonists contrasting cropping systems landscapes. We surveyed 13 crops northern France 2019, 19 2020. sampled (Aphis fabae Acyrthosiphon pisum) (Syrphidae, Coccinellidae mummy-forming parasitoids) three dates during spring, visual observation. assessed provided spontaneous margins collected data practices land use surrounding landscape. found that percentage flowering species edges accessible nectar to had a positive effect abundance Syrphidae aphid mummies plants.

Nevertheless, did not prevent rates both species, highlighting need alternative methods controlling populations.

The performance of cowpea aphid, Aphis craccivora Koch. (Hemiptera: Aphididae), on five faba bean, Vicia faba L. (Fabales: Fabaceae) cultivars was evaluated. Colony development, biology, and demographic parameters were studied to measure the cowpea aphid performance. Two methods, whole plant and detached leaf, were used in these experiments. After 14 d , the number of apterous adult, nymphs, an...

Landscape diversification is a key element for the development of sustainable agriculture. This study explores whether the implementation of habitats for pest natural enemies enhances conservation biological control in an adjacent field. In the present study conducted in Gembloux (Belgium) in 2016, the effect of two different habitats (wildflower strips and a forest) and aphid abundance on the ...
