Summary: Drought stress impacts the physiology and population growth of brown planthoppers (BPH). BPH feeding on drought-stressed rice have lower population numbers and exhibit negative physiological changes, including decreased water content and osmotic pressure, as well as altered glucose content and glutathione S-transferase (GST) activity. The expression of reproductive-related genes is also affected. Flight muscle size and mitochondrial abundance in BPH are decreased under drought stress.

Summary: Recent studies have found that treating rice seeds with the microbial metabolite decoyinine (DCY) can improve rice growth and yield, as well as suppress the brown planthopper (BPH). Feeding on rice seedlings grown from DCY-primed seeds significantly affected BPH's adult longevity, oviposition period, fecundity, and population parameters. The honeydew excretions and weights of BPHs fed on DCY-pretreated rice plants were reduced, and their feeding and oviposition preferences for these plants were also decreased.

Summary: This study reveals that the egg-associated secretions (EAS) from brown planthoppers (BPH) significantly affect the immunity of rice and enhance plant defenses in both rice and tobacco. The proteome analysis of EAS identifies several proteins that may have evolutionary conservation of effector functions across feeding and oviposition, providing valuable information for effector studies.

Summary: The variability of BPH populations and diversity of the host rice germplasm serve as an ideal model for exploring the genetic and molecular basis of insect-plant interactions. Nine major BPH resistance genes have been cloned, shedding light on the molecular basis of the rice-BPH interaction. Understanding the interactions between BPH and rice will provide novel insights for sustainable pest control.

Summary: The interaction between food crops and insect pests is mediated by semiochemicals emitted from host plants. The study identified eight rice neuroactive semiochemicals and found that uninfested plants emit semiochemicals that are attractive to pests, but this attractiveness can be reduced by adding a blend mimicking the composition of semiochemicals emitted by infested plants. This research suggests a mechanism for the spread of pest infestation from infested plants to nearby uninfested plants, which can be used for crop protection strategies.

Summary: This study identified a brown planthopper (BPH)-inducible promoter and three positive regulatory regions within it in rice. Transgenic rice with a gene driven by this promoter and positive regions exhibited an expected lethal effect on BPH, providing a novel approach for selecting insect-resistant tools in the future.

Summary: The planting of oilseed crops and flowering plants in rice fields can attract natural enemies, reduce the population of brown planthoppers, delay their appearance, and increase rice yields. Therefore, ecological engineering techniques should be included in the Integrated Pest Management program for rice crops.

Summary: In this study, a highly pathogenic native fungal strain against brown planthopper (BPH) was isolated and identified as a strain of Aspergillus fumigatus. Transcriptomic sequencing analysis revealed differentially expressed genes involved in host immune defense and cell detoxification in BPH against fungal attack. Knockdown of an upregulated gene encoding a serine protease (NlSPN) significantly decreased BPH survival. Combination of dsRNA injection and fungal infection showed an additive effect on BPH mortality, providing clues for new pest management strategies against BPH.

Summary: This study found that expression levels of serotonin biosynthesis genes and serotonin content in rice were significantly induced by brown planthopper (BPH) nymph infestation. Serotonin application increased the attractiveness and feeding behavior of BPH nymphs on rice seedlings, as well as their survival rates. Moreover, exogenous serotonin application increased the injury scale and functional plant loss indices caused by BPH nymph infestation.

Summary: Rice, an important food crop, is often affected by insect pests such as the brown planthopper. This study investigates the biochemical and defense enzyme activities in different genotypes of red rice resistant to the brown planthopper. The results show that highly resistant genotypes exhibit higher levels of defense enzyme activity, and six highly resistant genotypes have been identified.

Summary: Rice is a staple food for over half of the world's population, but its production is often threatened by the brown planthopper (BPH), a host-specific pest. Utilizing host resistance has been found to be a cost-effective method to control BPH. Research has identified numerous BPH-resistance genes/QTLs in rice, and the response of rice to BPH feeding involves various biological processes. Secretory proteins of BPHs have also been found to play a role in activating or suppressing rice's defense responses.
