“…Honeydew availability varied during the season with total aphid abundances and was higher in oats at the beginning and higher in vetch at the end. Mixing cereals and leguminous plants has been shown to reduce the incidence of some aphids by bottom-up control [59][60][61][62]. It could explain why there were fewer aphids in the mixed intercrop, even if our initial hypothesis was rather to attract a higher number of parasitoids with the presence of hosts, honeydew and extrafloral nectar combined and produce a top-down regulation.…”

Providing Alternative Hosts and Nectar to Aphid Parasitoids in a Plum Orchard to Determine Resource Complementarity and Distance Range Effect on Biological Control

There are many different practices that contribute to conservation biological control, but little is known about their complementarity. We tested the effects of providing food and alternative hosts to parasitoids by intercropping a plum orchard with companion plants. Oats and vetch were intercropped into the orchard either as single-species (oats or vetch) or two-species (oats and vetch combined) intercrops within an inter-row. The trophic resources provided by these intercrops were assessed, along with the incidences of aphids and their parasitoids in plum trees. We found up to ten alternative host species provided by oats and vetch, and extrafloral nectar was available from the vetch and mixed strips. An effect of intercrop type and distance to plum trees was observed on aphid incidence during one sampling period. Parasitism rates in exclusion cages were affected by intercrop type, reaching almost 60% close to the mixed intercrop. However, no general tendency was observed upon whether oats, vetch or their mixture was associated with a lower incidence of aphids. We found no evidence that providing effective sources of food and alternative hosts for parasitoids increased aphid mortality in this study. The context-dependent efficiency of intercropping is discussed.

“…If mechanical weed control is not possible for the intercrop in the same row, spraying is necessary. In addition, certain pests such as pigeons, aphids, pea Sitones, and Mycosphaerella pinodes must still be controlled [20,55,[60][61][62][63][64][65]. This must be done in addition to disease treatments that may be necessary for both species despite the beneficial effect that intercropping has on pathogen dynamics [66].…”

Beyond the ecosystem benefits of diversification through wheat–pea intercropping, this review analyzes the barriers and levers to its adoption and diffusion. The present review shows that structuring the value chain around the products of this innovative cropping system faces a set of technical (i.e., varietal selection, phytosanitary issue control, crop management sequence, collection management, and storage), economic (i.e., cost, price, market opportunities, and contracting), and public policy (i.e., subsidies for ecosystem services provided by intercropping) obstacles that contribute to its slow adoption and dissemination in Europe. However, the value chain resulting from the wheat–pea intercropping system has levers to be exploited at all levels, particularly in terms of its competitive advantages, ecosystem benefits, and superior product quality. The results of this review help to identify priorities that actors of the value chain can address to better focus their efforts on significant problems and solutions that can accelerate the adoption and dissemination of this agroecological system.

“…Teelten met gemixte cultivars zijn een effectieve strategie om sommige ziekten te beheersen en er wordt onderzocht of het ook kan bijdragen aan het onderdrukken van plagen, waaronder bladluis in graan (Shoffner en Tooker, 2013;Mansion-Vaquié et al 2019;Grettenberger and Tooker, 2017).…”

“…De planten in de mengteelt gaven meer vluchtige organische stoffen af (VOC's) dan de planten in de monocultuur en de onderzoekers denken dat dit mogelijk de bladluizen heeft beïnvloed. Andere onderzoeken hebben geen of een minimaal effect laten zien van een mengteelt ten opzicht van de monocultuur (Mansion-Vaquié et al 2019;Grettenberger and Tooker, 2017). Grettenberger and Tooker (2017) zagen daarentegen wel meer lieveheersbeestjes in de mengteelt ten opzicht van de monocultuur.…”
