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: In this study, it was found that inhibiting the activity of UGT enzyme effectively increased the toxicity of chlorpyrifos to the chlorpyrifos-resistant strain of Nilaparvata lugens. The resistant strain showed higher content of UGT compared to the susceptible strain. Four UGT genes (UGT386H2, UGT386J2, UGT386N2, and UGT386P1) were significantly overexpressed in the resistant strain and could be induced by chlorpyrifos. Knockdown of UGT386H2 or UGT386P1 increased the susceptibility of the resistant strain to chlorpyrifos. These findings suggest that overexpression of these two UGT genes contributes to chlorpyrifos resistance in N. lugens.

Summary: The salivary protein NlDNAJB9 of the brown planthopper triggers plant immune responses, in which the DNAJ domain plays an important role. NlDNAJB9 and its orthologs can induce ROS burst and cell death in plants, providing new insights into the molecular mechanisms of insect-plant interactions.

Summary: Carboxylesterases (CarEs) are an important detoxification enzyme family in insecticide resistance, with specific genes in the insect Nilaparvata lugens being identified and shown to be induced by various insecticides. Tissue-specific expression analysis showed certain CarE genes are highly expressed in the midgut and fat body, while others are more highly expressed in the head. The NlCarE1 gene was identified as a main candidate gene for nitenpyram resistance, with evidence suggesting a cooperative relationship with NlCarE19 in resistance formation. These findings provide a foundation for further understanding of insecticide resistance mediated by CarE in N. lugens.

Summary: By utilizing two different methods, this study evaluated the effects of pymetrozine on the fecundity of N. lugens and determined the resistance levels of different populations. The results showed that pymetrozine significantly inhibited the reproductive behavior of N. lugens, but only a few populations exhibited moderate or low levels of resistance, indicating that pymetrozine can still achieve effective control on the next generation of N. lugens.

Summary: The interactive effects of nitrogen input and pathogen infection on the behavior of rice plants, brown planthoppers, and their natural enemies were evaluated in this study. It was found that nitrogen application and Xanthomonas oryzae pv. oryzae (Xoo) infection influenced the preferences of brown planthoppers and their parasitoids for infected rice plants. Plant hormones JA and SA played important roles in regulating the composition of rice volatiles and altering the preferences of the insects. Xoo infection had a greater impact on plant volatiles and phytohormones than nitrogen fertilizer.

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: The study found that miRNA novel_268 is involved in the resistance of Nilaparvata lugens to nitenpyram and clothianidin by targeting the ABC transporter NlABCG3. These results provide more insights into the transcriptional regulation of ABC transporters in the insecticide resistance of N. lugens.

Summary: Nilaparvata lugens has developed a high level of resistance to pymetrozine. Pymetrozine-resistant brown planthopper showed cross-resistance with some neonicotinoids such as dinotefuran, nitenpyram, and sulfoxaflor. The resistance to pymetrozine in N. lugens was found to be polygenic, autosomal, and incompletely dominant. The fitness costs associated with pymetrozine resistance can be utilized in insect resistance management strategies to prolong the effectiveness of pymetrozine for controlling N. lugens in China.

Summary: The study investigates the role of NlOBP3 in the resistance of N. lugens to nitenpyram and sulfoxaflor. It reveals that NlOBP3 is overexpressed and associated with the resistance, and silencing NlOBP3 increases the mortality rate of N. lugens to the two insecticides.

Summary: The transcription factor activator protein 1 (AP-1) was found to be overexpressed in clothianidin-resistant strains of Nilaparvata lugens and field resistant populations. Silencing of NlAP-1 decreased CYP6ER1 expression and increased susceptibility to clothianidin in N. lugens. NlAP-1 bound to the CYP6ER1 promoter and regulated its expression, providing insights into the transcriptional regulation of insecticide resistance in insect pests.

Summary: The study confirmed the relationship between nitenpyram resistance and overexpression of key metabolic enzyme genes CYP6ER1 and CarE1 in Nilaparvata lugens, and highlighted the importance of miRNAs in nitenpyram resistance. Global screening identified known and novel miRNAs associated with nitenpyram resistance, with two miRNAs (novel_85 and novel_191) targeting CYP6ER1 and CarE1, respectively, demonstrating their regulatory role in insecticide resistance. Modulating the expression of these miRNAs significantly altered nitenpyram susceptibility in N. lugens, suggesting their potential as new targets in insecticide resistance management.
