“…Our findings add to the recent evidence from observational data in oilseed rape that pollination and biocontrol negatively interactively affect crop yield (Bartomeus et al, 2015), although several other studies described in a recent review found a positive interactive effect (Garibaldi et al, 2018). However, since the combined effects of ecosystem services on crop yield is an emerging question in agroecology, the number of studies to date is low and generality of findings remains to be proven.…”

“…We found a consistent negative, interactive effect (antagonism) between pollination and biocontrol on boll retention in both greenhouse and field experiments, despite the different types of pests (see Lundin et al, 2013 andGaribaldi et al, 2018 for a conceptual graph).…”

“…Alternatively, a negative non-additive effect (antagonism) would result when pollination benefits crop yield only at low biocontrol, or these two services can independently (additively) affect yield. In all these cases, crop yield is expected to be limited by more than one factor, thereby supporting the "multiple limitation hypothesis" that proposes the optimization of plant behaviour to balance costs and benefits of multiple resource acquisition (Garibaldi et al, 2018;Gleeson & Tilman, 1992). If only one ecosystem service limits yield, the "Liebig's law of the minimum" is supported and it states that the resources in shortest supply relative to demand is limiting plant yield (Von Liebig, 1840).…”

“…This finding supports "Liebig's law of the minimum" hypothesis (Von Liebig, 1840) according to which we would expect cotton yield to be limited only by one of these two ecosystem services, that is, biocontrol. However, both greenhouse experiment and the field study also showed negative coefficients for the interactive effects (antagonism, sensu Garibaldi et al, 2018) between pollination and biocontrol. More specifically, pollination substantially improved boll retention and yield at simulated low levels of biocontrol in the greenhouse experiment.…”

1. Insect pollination and biological pest control simultaneously influence crop yield, but are often investigated individually. This can lead to under-or over-estimation of the importance of individual services when they interact to affect yield. Recent, limited evidence from field studies showed contrasting results with both additive and non-additive positive and negative effects.2. To disentangle the mechanisms underlying these responses, we conducted a greenhouse experiment and a field study. We tested the potential and realized contribution of insect pollination to cotton boll retention and yield under various pest pressures and biocontrol levels.3. We found both additive and interactive effects of insect pollination and biocontrol within a single crop system depending on the level of pest pressure. In the greenhouse experiment, pollination did not contribute to cotton boll retention and final yield at low pest pressure. At high pest abundances, boll retention and final yield were higher when pollinators were present. In the field study, pollination was sufficient to alter the negative effect of pests on boll retention. Thus, interactive effect between the two ecosystem services on boll retention was present at high pest pressure in the greenhouse and at natural levels of pest pressure in the field, but not at lower pest abundances in controlled conditions. 4. Although cotton plants partly compensated for bolls shedding by increasing their weight in the greenhouse experiment, this effect was not detected in the field study, likely due to higher environmental variation. Similarly, interactive effect of pollination and biocontrol on the final yield was present only in the greenhouse study. Synthesis and applications.We conclude that the contrasting findings of additive versus non-additive effects between ecosystem services may be due to the levels of services and disservices tested and environmental variation. Further, this study shows that even when an ecosystem service does not appear to limit crop yield, it can make a substantial contribution to yield and act as insurance when the other service is reduced. For achieving food and fibre security, it is essential that future studies test interactive effects between these ecosystem services in different systems and environmental conditions.

Plant damage in urban agroecosystems varies with local and landscape factors

Citation: Egerer, M., H. Liere, A. Lucatero, and S. M. Philpott. 2020. Plant damage in urban agroecosystems varies with local and landscape factors. Ecosphere 11(3):Abstract. Biotic and abiotic factors at local to landscape scales influence insect pest and disease dynamics in agricultural systems. However, relative to studies focused on the importance of these drivers of crop plant damage in rural agricultural systems, few studies investigate plant damage from herbivore insects and plant diseases in urban agroecosystems, and consequently, most urban farmers lack knowledge on crop protection tactics. Here we use three common crop species within urban agroecosystems (community gardens) distributed across an urban landscape as a model system to ask how local, landscape, and microclimate factors relate to herbivore and disease plant damage. We hypothesized that plant damage would be lower in gardens with greater local vegetation complexity, landscape-scale complexity, and less variable temperatures, but that the importance of factors is species-and damage-specific. By measuring Brassica, cucurbit, and tomato insect pest and disease damage across the growing season, we confirmed that the importance of factors varies with crop species and by damage type. Both local complexity factors (e.g., number of trees and shrubs) and landscape complexity (percent natural cover in the landscape) relate to lower incidence of herbivore and disease damage on some crops, supporting our prediction that habitat heterogeneity at both local and landscape scales lowers plant damage. Greater temperature variability related to higher disease damage on tomatoes linking microclimate factors to disease prevalence. Yet, local complexity factors also related to higher incidence of plant damage for other crop species, indicating variable species-level impacts of local management factors on plant damage. By measuring the abundance of fungus-feeding lady beetles (Psyllobora) on cucurbits, we confirmed a strong association between natural enemies and powdery mildew. We provide a case study on how changes in local to landscape-scale factors relate to plant damage in urban agroecosystems and suggest how urban farmers and gardeners can apply this ecological knowledge to improve sustainable urban food production.

Climate change and managing insect pests and beneficials in agricultural systems

Climate change is expected to alter pressure from insect pests and the effectiveness of insect pollinators across diverse agricultural systems globally. In response to warming, insects are undergoing or are projected to undergo shifts in their geographic ranges, voltinism, abundance, and phenology. Effects on the focal insect species can be affected directly or indirectly, through their interactions with other species at higher and lower trophic levels. These climate‐driven effects are complex and as a result variable, sometimes increasing pest pressure or reducing pollination and sometimes with opposite effects depending on climatic baseline conditions and the interplay of contributing drivers. This uncertainty prevents effective responses. Furthermore, in addition to effects of climate change on insect pests and pollinators, projected and ongoing climate change is incentivizing changes in cropping systems such as altered tillage and increasing diversification and intensification with the potential to alter pests and pollinators as great as climate itself. Preparing for this uncertainty must be included in a framework for “Climate‐smart Integrated Pest and Pollinator Management,” as a component of agricultural production under climate change.
