Generic characteristics of genus Alnetoidia Dlabola are revised based on study of nine species from China, including two new species: A. (Alnetoidia) gracilis, A. (Alnella) dentata spp. nov., and four new records to China. A key to species for identification of Chinese adult males is provided.

Mixed infections of plant viruses are common in crops and represent a critical biotic factor with substantial epidemiological implications for plant viral diseases. Compared to single-virus infections, mixed infections arise from simultaneous or sequential infections, which can inevitably affect the ecology and evolution of the diseases. These infections can either exacerbate or ameliorate symptom severity, including virus-virus interactions within the same host that may influence a range of viral traits associated with disease emergence.

This review provides a comprehensive overview of the current understanding of rice resistance to the brown planthopper (BPH), a major pest that poses significant threats to rice production through direct feeding damage and by transmitting viruses such as Rice grassy stunt virus (RGSV) and Rice ragged stunt virus (RRSV). We highlight the emergence of various BPH biotypes that have overcome specific resistance genes in rice. Advances in genetic mapping and cloning have identified 17 BPH resistance genes, classified into typical R genes encoding nucleotide-binding leucine-rich repeat (NLR) proteins and atypical R genes such as lectin receptor kinases and proteins affecting cell wall composition.

The brown planthopper (BPH; Stål) is the most significant insect pest compromising rice production globally. Phytohormones, which are small organic compounds produced by plants, play a crucial role in regulating plant growth and development. Nevertheless, extensive research has established that phytohormones are essential in modulating plant defense against BPH.

Flavescence dorée (FD) poses a significant threat to grapevine health, with the American grapevine leafhopper, , serving as the primary vector. FD is responsible for yield losses and high production costs due to mandatory insecticide treatments, infected plant uprooting, and replanting. Another potential FD vector is the mosaic leafhopper, , commonly found in agroecosystems.

Rice ( L.) feeds half the world's population and serves as one of the most vital staple food crops globally. The brown planthopper (BPH, Stål), a major piercing-sucking herbivore specific to rice, accounts for large yield losses annually in rice-growing areas.
