“…The increase in leafhopper density was attributed to their preference for well-irrigated, vigorously growing vines. In contrast, Berndt et al (2006) showed that parasitism of leafhoppers was very variable and not always explained by the introduction of buckwheat flowers in the vineyards. These results show that habitat manipulation can enhance parasitism rate but is very tricky to manage to reduce damage done by leafrollers (Berndt et al, 2006).…”

“…Indeed, this technique may provide flowers or other resources and a better quality habitat for natural enemies. This was examined in vineyards by adding flowering buckwheat (Fagopyrum esculentum Moench) and assessing its effect on the parasitism rate of the leafroller (Lepidoptera: Tortricidae) larvae (Berndt et al, 2006). Recently, Irvin et al (2016) assessed the effect of an irrigated buckwheat service crop on populations of beneficial insects and grape pests in a commercial organic vineyard in southern California.…”

Service crops are crops grown with the aim of providing non-marketed ecosystem services, i.e. differing from food, fiber and fuel production. Vineyard soils face various agronomic issues such as poor organic carbon levels, erosion, fertility losses, and numerous studies have highlighted the ability of service crops to address these issues. In addition to their ability to increase soil organic matter and fertility, and reduce runoff and erosion processes, service crops provide a large variety of ecosystem services in vineyards such as weed control, pest and disease regulation, water supply, water purification, improvement of field trafficability and maintenance of soil biodiversity. However, associating service crops with grapevines may also generate disservices and impair grape production: competition for soil resources with the grapevine is often highlighted to reject such association. Consequently, vinegrowers have to find a balance between services and disservices, depending on local soil and climate conditions, on their objectives of grape production and on the nature and temporality of the ecosystem services they expect during the grapevine cycle. This study proposes a review of the services and disservices provided by service crops in vineyards, and a framework for their management. Vinegrowers' production objectives and pedoclimatic constraints form the preliminary stage to consider before defining a strategy of service crop management. This strategy assembles management options such as the choice of species, its spatial distribution within the vineyard, the timing of its installation, maintenance and destruction. These management options, defined for both annual and long-term time scales, form action levers which may impact cropping system functioning. Finally, we underline the importance of implementing an adaptive strategy at the seasonal time scale. Such tactical management allows adapting the cropping system to observed climate and state of the biophysical system during the grapevine cycle, in order to provide targeted services and achieve satisfactory production objectives.

“…Availability of flowering buckwheat (Fagopyrum esculentum Moench) (Scarratt 2005) and alyssum (Lobularia maritima (L.)) (Berndt and Wratten 2005) can increase fecundity and longevity and increase the proportion of female offspring of Dolichogenidea tasmanica Cameron, a key parasitoid of the leafrollers. Parasitism rates and leafroller densities have been shown to increase and decrease respectively in vineyards close to buckwheat and alyssum (Scarratt 2005;Irvin et al 2006), although 6 increased parasitism rates and/or decreased pest densities has not been achieved in all trials (Berndt et al 2002;Berndt et al 2006). Recent unpublished data indicate that leafroller densities can in some cases be reduced to below the economic threshold when flowering buckwheat is available.…”

Exotic invaders are some of the most serious insect pests of agricultural crops around the globe. Increasingly, the structure of landscape and habitat is recognized as having a major influence on both insect pests and their natural enemies.Habitat manipulation that aims at conserving natural enemies can potentially contribute to safer and more effective control of invasive pests. In this paper, we review habitat management experiments, published during the last ten years, which have aimed to improve biological control of invasive pests. We then discuss during what conditions habitat management to conserve natural enemies is likely to be effective and how the likelihood of success of such methods can be improved. We finally suggest an ecologically driven research agenda for habitat management programmes.2

“…El néctar de las flores se sabe que incrementa la tasa de parasitismo en muchas especies (Bianchi y Wäckers, 2008). Otras fuentes de alimento son el polen, el néctar extrafloral y la melaza producida por algunos hemípteros (Bugg y Waddington, 1994;Berndt et al, 2006). English-Loeb et al (2003) demuestran que las especies de…”
