| Abstract | In this study, we attempted to elucidate the interaction effects of Rice ragged stunt virus (RRSV) infection on the developmental and survival periods of the brown planthopper (BPH, Nilaparvata lugens St?l). BPH is an insect pest that is important for the transmission of rice viral diseases in irrigated rice cultivation in Thailand. This experiment was conducted in a 2 ? 2 factorial in a completely randomised design (CRD) with five replications for the assessment of interaction effects between the statuses of BPH populations and rice plants. The results indicated that there were significant interactions (p < 0.05) among the developmental periods of the second-instar nymph BPH stage, and survival periods of adult BPH stages between the statuses of BPH vectors and rice plants. In addition, the effects of different RRSV inoculation periods on the developmental and survival periods of each life cycle stage of the nonviruliferous BPH population were investigated following CRD with five replications. Our results showed a significant difference (p < 0.05) in the developmental periods of the instar nymphs and in the survival periods of adults. A better understanding of the interaction between BPH vectors and rice plants is needed, a benefit of the complex of plantvirusvector interactions, as the BPH vector is well adapted to the rice host plant, either with or without RRSV. The results can be used to provide insights into how RRSV spreads in irrigated rice fields, to discern the BPH survivorship pattern, and to improve plant protection strategies for agroecosystem management in Thailand. |
