Agroecosystems are often complex ecosystems with diverse food webs. Changes in food web complexity may have important context-dependent consequences for pest control strategies. The success of predator introductions to suppress pests may depend on the diversity of pests. For crops with diverse pest assemblages, it is hypothesized that diverse predator communities are needed to suppress diverse pest assemblages below damaging levels. In this study, we compare the ability of ant predator monocultures and polycultures to suppress single- and diverse- (three species) pest assemblages in a coffee foodweb. We use a factorial experiment that compared treatments of predator and pest diversity to understand the impact of pest diversity on multiple predator effects. We show that predator polycultures enhanced pest risk relative to predator monocultures significantly more in the diverse-pest treatment relative to in the single-pest treatments for two of three pest species. Further, we show that pest diversity significantly reduced pest risk in all predator treatments except for the predator polyculture treatment. These results suggest that pest diversity may reduce the efficiency of single predator species at suppressing pest damage, but do not limit multiple predator species. This in turn leads to stronger effects of predator diversity with greater pest diversity. These results highlight the need to consider foodweb complexity, such as pest diversity, when designing and implementing biology control programs.

Patch composition structure and landscape pattern at different spatial scales have great variation. Scale effect is also an important characteristics in agricultural landscape. In recent years, both agricultural management within field and landscape modification at landscale scale were used to achieve ecologically based pest management and ecosystem services. Ecologically based pest management should be conducted at multiple spatial scales, especially the combination of farming activities at local scale and patch pattern at landscape scale. Optimization of planting pattern and agricultural management at local scale and landscape modification at landscape scale should be considered together, which could cut off the life history of agricultural and recover the population of natural enemy. Then, the agroecosystem health and biological control service was enhanced at most extent. We also summarized the mechanism and hypothesis between environmental conditions and biological control in agroecosystem. At local scale, rotation, cover crop, no-tillage, and organic management could be used to enhance crop health and biocontrol service, which were also improved by the rearrangements of habitat patches and plant resource at landscape scale. Additionally, habitat management should be conducted at multiple spatial scales. The landscape characteristics at different spatial scales have varied effects on insects due to the species specific. In recent years, great progress has been obtained through landscape design in the USA and Europe. The varied responses of different species to spatial scales may be important unexplored fields in pest sustainable management. The research landscape pattern and biodiversity can reveal the interspecific relationship and mechanism in theory, which can provide new approaches and methods to control insect pests by landscape design in practice.

“…This leads to a decline in natural habitats and crop diversity, which may be beneficial for pest outbreaks [4][5][6]. Reasonable land use forms and rotation patterns at the large-scale landscape level, habitat patch types, crop tillage or cultivation patterns, variety mix, and layout on a field-by-field basis can mitigate this impact [7,8]. For example, planting wildflowers and leaving grassland and hedgerow strips beside cultivated lands can promote natural enemies' diversity and improve the colonization of ground predators [9,10].…”

The rotation patterns of summer rice–winter oil seed rape and summer rice–winter fallow are the main planting regimes in the rice ecosystem in southern China. However, the impact of local rotation patterns and landscape factors on the overwintering conservation of predators in spider and epigaeic beetle assemblages remains poorly understood. Here, we investigate the diversity and density of spiders and beetles over two consecutive winters (2019/2020 and 2020/2021), focusing on the impact of two rotation patterns (rice–fallow and rice–oilseed rape) and surrounding landscape compositions on predator diversity. The main findings of our research were that spiders were more abundant and had a higher activity density in the fallow rice fields (FRs) compared to the oilseed rape fields (OSRs), whereas ground beetles exhibited the opposite pattern. Specifically, fallow rice fields supported small and ballooning spiders (e.g., dominant spider: Ummeliata insecticeps), while OSRs supported larger ground beetles (e.g., dominant beetles: Agonum chalcomus and Pterostichus liodactylus). Moreover, the composition of spider assemblages were impacted by semi-natural habitats (SNHs) during overwintering, while ground beetle assemblages were influenced by overwinter planting patterns. Overall, our results suggest that different planting regimes and preserving semi-natural habitats are a strategic way to enhance species diversity and functional diversity of ground predators. It is, therefore, recommended that to conserve and improve predator diversity during overwintering, land managers and farmers should aim to maintain diverse planting regimes and conserve local semi-natural habitats.
