The intercropping pattern promotes the sustainable development of efficient agriculture, especially cash crops, such as L. and Roxb. intercropping plantation in China. However, the mechanisms underlying intercropping pattern effects on soil microbial community diversity and composition are poorly understood. A monoculture and intercropping field experiment of the two crops was established to monitor the changes of soil physicochemical properties, enzyme activities, microbial (bacterial and fungal) diversity, and composition. Soil bacterial rather than fungal communities' diversity is more sensitive to intercropping pattern. The intercropping significantly decreased rhizospheric bacterial diversity of L. by 4.21%, and the decrease of soil nutrient content may be the main reason for the change of soil enzyme activity, bacterial community diversity, and composition structure under intercropping pattern. Supplementing nutrients to the soil of intercropping systems is conducive to maintain soil health and ecosystem functional stability in the tropical compound cultivation plantation.

Global food security relies on wheat, maize, and soybean, yet their cultivation faces escalating threats from Fusarium head blight (FHB) pathogens. We demonstrate that agricultural intensification enables cross-kingdom root infections by and across these crops. Screening of 180 strains revealed tripartite host infectivity, with transcriptomics uncovering host-adapted virulence strategies.

This study assessed the host plant selection behavior of female stalk-eyed flies (SEFs) or , where a Y-tube olfactometer was used to compare SEF attraction to the odor of leaves from four rice varieties (ITA306, WAB56-104, CG14, and RAM55). Another step of the evaluation consisted of pairing leaf odors from two rice varieties. Also, potted plants of the tested varieties were displayed in a screened cage and submitted to female SEF selection.

Crop-field structural management for boosting arthropod pest bio-control is increasingly recognized as an environmentally sustainable alternative to chemical pesticides. However, how natural pest regulation outcomes may be undermined by intraguild predation among pest natural enemies is seldom investigated in cereal crops-fields. Here we use δ13C and δ15N stable isotope analyses to assess intraguild predation amongst five arthropod taxa, comparing this to their consumption of three pest taxa, and test how such patterns relate to farming system (low-intensity/conventional) or cropping method (monoculture/intercropping) across 15 small non-transgenic maize fields.

This study evaluated 460 soybean accessions from a global germplasm collection at two contrasting locations in China: Heilongjiang (HLJ) and Inner Mongolia (NM). The experiment used a split-plot design within a randomized complete block setup, with three replications at each site.
