Effects of Priming Rice Seeds with Decoyinine on Fitness Traits and Virus Transmission Ability of the Small Brown Planthopper, Laodelphax striatellus

Laodelphax striatellus is a notorious sap-feeding insect that also serves as vector of rice stripe virus (RSV) and responsible for significant decline in yield. Pesticide application remains crucial strategy controlling pests. In recent years, the utilization biopesticides has gained attention due to their eco-friendliness suitability pests pathogens agriculture. The present study aimed Figureto evaluate potential efficacy microbial pesticide, decoyinine (DCY), seed priming agent against SBPH’s biology, feeding behavior, RSV transmission ability laboratory. Here, we revealed body weight females males honeydew extraction RSV-virulent SBPH were (22.50%, 25.0%, 23.25%, respectively) significantly lower than non-virulent SBPH. Meanwhile, fecundity was higher (8.24%) However, nymphal survival (horizontal vertical) found be non-significantly affected by DCY application. Furthermore, DCY-primed seedlings prolonged time period frequency electrical penetration graph (EPG) waveforms (np, N2, N3), reduced waveform (N4-b) both strains with inoculation. provides new insights reducing fecundity, weight, contents, which might contribute modern integrated pest management.
