Expert opinion and model of natural pest control in agricultural landscapes
<table> <tbody> <tr> <td> <div>The survey asks expert How they would estimate the capacity different land use (herbaceous semi-natural habitat, forest edge, forest core) to support the abundance of the following insect groups in the landscape: ‘complete generalists’ ‘specialized predators’, ‘parasitoids’. The score is provided on a scale from 0 (no relevant capacity) to 10 (very high relevance). For each opinion, experts provided a level of confidence: 1 'I don’t feel confident with my score', 2 'I feel fairly confident with my score” and 3: 'I feel confident with my score'. In the same way experts were asked to rate a baseline scenario of agricultural fields defined as as a conventionally managed average field (with an average field size of 3-7 ha, fertilization and pesticide application compared to the region of interest) of medium crop diversity with three functional groups over 4 years (e.g., cereal, oilseed crop, root crop). Then experts were asked how much a single change from one practices to an alternative one (e.g., conventional to organic) would affect the score they provided - 50 to - 100% = considerably worse -20 to -50%= notably better -1 to -20% = slightly worse 0 = no change +1 to 20% = slightly better +20 to 50%= notably better + 50 to 100%= considerably better +100 to 200% = extremely better/</div> <div> </div> <div>Finally experts were asked about the distance at which landscape change affect the abundance of the three group of natural enemies.</div> <div> </div> <div>The survey was conducted from April to June 2021.</div> <div> </div> <div>The scores for each practices are derived by mixed effect model and provided in the file Code_Habitats.csv.

Bt cotton area contraction drives regional pest resurgence, crop loss, and pesticide use
<p>Genetically-modified crops expressing Bacillus thuringiensis (Bt) proteins have been widely cultivated, permitting an effective non-chemical control of major agricultural pests. While their establishment can enable an area-wide suppression of polyphagous herbivores, no information is available on the impact of Bt crop abandonment in entire landscape matrices. Here, we detail a resurgence of the cosmopolitan bollworm <em>Helicoverpa armigera</em> following a contraction of Bt cotton area in dynamic agro-landscapes over 2007–2019 in North China Plain. An 80% reduction in Bt cotton was mirrored in a 1.9-fold increase of ambient H. armigera population levels, culminating in 1.5–2.1-fold higher yield loss and a 2.0–4.4-fold increase in pesticide use frequency in non-Bt crops (i.e. maize, peanut, soybean). Our work unveils the fate of herbivorous insect populations following a progressive dis-use of insecticidal crop cultivars, and hints at how tactically deployed Bt crops could be paired with agro-ecological measures to mitigate the environmental footprint of crop production.</p>

Diamonds indicate the mean and bolded lines indicate the median. Boxes are +/- 25%, lines represent minimum and maximum values excluding extreme values, and dots indicate data points > 1.5 farther from the box edge than the interquartile range. Lower case letters indicate differences from Mann-Whitney post-hoc analyses. B. The proportion of grasshoppers surviving through time on each diet treatment. Most diet treatments did not have individuals die until the 5th day of the experiment, and most treatments except 7p:35c had minimal deaths (although there were no significant differences among treatments). C. Proportion of grasshoppers molting to adults over time. Most of the diets saw increases in molting from days 5–7, except diet treatment 7p:35c, which was delayed and had the least number of grasshoppers successfully molt (significantly different from all other treatments).

Data for: An aggressive non-consumptive effect mediates pest control and multi-predator interactions in a coffee agroecosystem
<p class="MsoNormal">Natural pest control is an alternative to pesticide use in agriculture, which may help to curb insect declines and promote crop production. Non-consumptive interactions in natural pest control, which historically have received far less attention than consumptive interactions, may have distinct impacts on pest damage suppression and may also mediate positive multi-predator interactions. Additionally, when non-consumptive effects are driven by natural enemy aggression, variation in alternative resources for enemies may impact the strength of pest control. Here we study control of the coffee berry borer (CBB), <em>Hypothenemus hampei</em>, by a keystone arboreal ant species, <em>Azteca sericeasur</em>, which exhibits a non-consumptive effect on CBB by throwing them off coffee plants. We conducted two experiments to investigate: 1) if the strength of this behavior is driven by spatial or temporal variability in scale insect density (an alternative resource which <em>Azteca</em> tends for honeydew), 2) if this behavior mediates positive interactions between <em>Azteca</em> and other ground-foraging ants, and 3) the effect this behavior has on the overall suppression of CBB damage in multi-predator scenarios. Our behavioral experiment showed that nearly all interactions between <em>Azteca</em> and CBB are non-consumptive and that this behavior occurs more frequently in the dry season and with higher densities of scale insects on coffee branches. Our multi-predator experiment revealed that borers thrown off coffee plants by <em>Azteca</em> can survive and potentially damage other nearby plants but may be suppressed by ground-foraging ants. Although we found no non-additive effects between <em>Azteca</em> and ground-foraging ants on overall CBB damage, together, both species resulted in the lowest level of plant damage with the subsequent reduction in "spillover" damage caused by thrown CBB, indicating spatial complementarity between predators. These results present a unique case of natural pest control, where damage suppression is driven almost exclusively by non-consumptive natural enemy aggression, as opposed to consumption or prey behavioral changes. Furthermore, our results demonstrate the variability that may occur in non-consumptive pest control interactions when natural enemy aggressive behavior is impacted by alternative resources, and also show how these non-consumptive effects can mediate positive interactions between natural enemies to enhance overall crop damage reduction.</p>
