“…Second, sites with higher herbivore richness could be more likely to contain a specific damaging pest. Our data shows high-herbivore-richness fields contained large numbers of aphids, a key canola pest (Reddy, 2017). We also found more chrysomelids, curculionids, meloids, scraptiids, pentatomids, and yponomeutids in sites with higher herbivore richness.…”

“…We also found more chrysomelids, curculionids, meloids, scraptiids, pentatomids, and yponomeutids in sites with higher herbivore richness. However, the only canola pests in these groups are seedpod weevils (Curculionidae), which damage a later crop stage than we sampled (Reddy, 2017). Our support for parasitoid richness increasing crop yield is mixed.…”

“…This classification considered both diet and reproductive strategy. Herbivores included major regional canola pests (thrips [Thysanoptera], aphids, flea beetles, cabbage seedpod weevils, and Lygus bugs Hahn; Reddy, 2017). Kleptoparasites are regulators of bee communities, and may reflect overall levels of pollinator biodiversity (Sheffield, Pindar, Packer, & Kevan, 2013).…”

“…Second, we asked if responses of functional groups to tillage depended on landscape context, given variation in mobility and habitat needs of unique organisms (Lichtenberg et al, 2017; Marja, Tscharntke, & Batáry, 2022). Third, we asked whether variation in arthropod communities interacted with tillage and landscape context to affect yield (Delaplane & Mayer, 2000; Morandin & Winston, 2005; Reddy, 2017). Reduced tillage often decreases crop yield (e.g., Lundin, 2019; Tamburini et al, 2020), but enhanced pest control or pollination could counteract this.…”

Agricultural diversification often promotes biodiversity and ecosystem services by increasing habitat diversity. However, responses to agricultural diversification are context dependent, differentially impacting functional groups of service-providing organisms and crop yields. Conservation and no tillage are promoted as agricultural diversification practices that increase soil heterogeneity and habitat diversity. Here we investigated whether soil tillage practices in canola crop fields altered arthropod biodiversity or yield, and how effects of field-scale diversification compared to landscape-scale habitat context. We focused on effects of high, medium, or no tillage on five functional groups with unique diets and reproductive strategies: (i) herbivores, (ii) kleptoparasites, (iii) parasitoids, (iv) pollinators, and (v) predators. Effects of agricultural diversification on arthropod abundance and diversity varied across functional groups. Pollinators responded to on-farm soil diversification, benefiting from medium tillage. Predators and herbivores responded most strongly to landscape-scale habitat composition and were more abundant in landscapes with more semi-natural habitat. However, variation in arthropod communities had little effect on canola crop yield, which was lowest in fields with no tillage. Policy implications: Our results indicate that natural history differences among arthropod functional groups mediate how habitat availability affects biodiversity. Crop yields, however, showed no response to biodiversity of ecosystem service providers. Our research highlights the need to determine the contexts in which soil diversification practices meet a multi-faceted goal of simultaneously supporting natural biodiversity, ecosystem services, and crop yield.

“…This natural enemy includes parasitoids, predators, and occasionally pathogens and vertebrates (Kenis et al, 2017). Various parasitic wasps lay their eggs inside aphids, turning the skin of parasitized aphids crusty and golden brown, known as mummies (Sarwar, 2017). Many predators, including lacewing larvae, lady beetle larvae and adult, syrphid fly larvae, and soldier beetles, feed on aphids (Flint, 2016).…”

Maize (Zea mays L.) is a vital cereal crop worldwide, crucial for global food security and various industrial applications. Its cultivation faces significant challenges from a diverse array of insect pests and pathogens, notably including the maize leaf aphid (Rhopalosiphum maidis) and the maize dwarf mosaic virus (MDMV). This paper explores the intricate interactions among maize, its insect vectors, and MDMV, emphasizing the urgent need for a deeper understanding to develop sustainable management strategies. Maize exhibits vast genetic diversity and is cultivated across diverse environments, making it susceptible to a range of pests and diseases. The transmission of MDMV by aphids, particularly R. maidis, poses a significant threat to maize production globally. The complex tripartite interaction between maize, aphids, and MDMV serves as an ideal model system for studying plant-insect-phytopathogen interactions. Understanding the components of this interaction is critical for developing effective management strategies. Despite significant research efforts, there remains a knowledge gap in the molecular mechanisms underlying vector-borne diseases. Further research on the molecular level is essential for identifying specific targets for genetic pest control and disrupting pathogen transmission by insect vectors. Developing countries, in particular, require intensified research efforts to address the growing challenges to food security and agricultural sustainability. Thus, unraveling the complexities of plant-insect-phytopathogen interactions is essential for devising effective strategies to combat vector-borne diseases and sustain global food systems. Enhanced scientific research, especially in developing regions, is crucial for addressing these challenges and ensuring food security for future generations.
