Special Issue Information

Dear Colleagues,

The study of plant–insect interaction has been a hot topic within research for some time. As a supporter, plants not only provide habitat, food and refuge for insects, but also transfer basic communication information between them. Meanwhile, when insects attack plants, they not only cause physical damage to plants, but also trigger underlying plant defense responses. Moreover, natural enemies use plant volatiles for host location and foraging. Therefore, the plant–insect interaction is complex.

Understanding the functioning of this complex of interacting species requires studies into their population dynamics in space and time and the underlying trophic and informational mechanisms. In recent years, with the rapid development of technologies and methods such as genomics, transcriptomics, proteomics, metabolomics, RNAi and gene editing, new opportunities and challenges have been provided that will enable us to explore the interactions between plants and insects in areas ranging from genes to ecosystems.

This Special Issue, entitled “Insect–Plant Interaction in Agroecosystems” will include interdisciplinary studies embracing agriculture with disciplines of biology, physiology, ecology and genomics. All types of articles are welcome, including original research, opinions and reviews. Research articles will cover a broad range of plant–insect interaction, with topics ranging from community to genes. In short, we hope that this Special Issue can not only deepen our understanding of plant–insect interaction, but also promote the development of new approaches to and technologies for pest control.

Cotton (Gossypium hirsutum) requires a long growing period for fruit and fiber maturation, making it vulnerable to insect pests, thus affecting the seed cotton yield and fiber quality. Cotton-feeding thrips (Thysanoptera: Thripidae) are one of the major insects impacting cotton yield throughout the U.S. cotton belt and worldwide. A two-year field research conducted at Texas A&M AgriLife Research farm in west Texas, USA quantified the interactive effect of three cover crops [wheat (Triticum aestivum), rye (Secale cereale), and no cover] and three irrigation regimes [rainfed, deficit irrigation (30%) and full irrigation] on thrips population dynamics across the phenologically susceptible stages of upland cotton and resulting impact on plant growth and yield parameters. Temporal densities of thrips, feeding injury from thrips, cotton growth and reproductive profiles, yield, and fiber quality varied with cover crops and irrigation levels. Thrips densities were conspicuously low due to harsh weather conditions, but the densities decreased with an increase in plant age. Terminated rye and wheat cover versus conventional-tilled, no-cover treatments showed marginal effects on thrips colonization and population dynamics. Similarly, full irrigation treatment supported higher thrips densities compared to rainfed and deficit irrigation treatments. Immature thrips densities increased through the successive sampling periods, indicating increased thrips reproduction following the initial colonization. Thrips feeding injury was significantly greater in no-cover plots in the early seedling stage, but the effect was insignificant across all cover crop treatments in subsequent sampling dates. The results of this study demonstrated increased seedling vigor, plant height, and flower densities in terminated cover crop plots across all irrigation regimes compared to that in no-cover plots. However, the cover crop x irrigation interaction significantly impacted the cotton lint yield, with increased lint yield on cover crop treatments. This study clearly demonstrates the value of cover crops in semi-arid agricultural production systems that are characterized by low rainfall, reduced irrigation capacity, and wind erosion of topsoil.
