“…Mantel test for IBD analysis showed nonsigni cant correlation between genetic and geographic distances of 22 N. lugens populations suggesting unrestricted gene ow among them. Similar to our results, IBD analysis result were found to be non-signi cant in different migratory insects like Apis gossypii (Nam et al 2019) and plant hoppers (Winnie et al 2020;Tyagi et al 2022). AMOVA analysis of molecular variance of 22 N. lugens population revealed a homogenous population with only 2% variation between the populations and 98% variation within the population.…”

“…In contrast, the Bay of Bengal branch is the main cause of rainfall in south-east and north-east India, which explains the even gene ow among south and east Indian populations in the present study. Homogeneity in N. lugens populations were also reported by earlier researchers, where majority of them were sampled from east and south India (Tyagi et al 2022). While the ΔK method in population structure analysis again identi ed…”

Brown planthopper, Nilaparvata lugens (Stål.) is one of the most ruinous pest of rice in south-east Asia. This insect had the tendency to express differential reaction to resistant rice cultivars and various insecticide groups in different geographic locations. Therefore, genetic diversity among the N. lugens populations is required to be understood for their effective management. Hence, in the present study, genetic structure and genetic diversity of 22 N. lugens populations collected from 22 hotspot regions of India were studied with genomic simple sequence repeats (NlSSR) markers. Results revealed that mean genetic diversity was 0.399 and polymorphic information content (PIC) was 0.337 in the 30 selected SSR markers. Further, molecular variance (AMOVA) revealed only 2% variation among population and 98% within the populations. In cluster and population structure analysis, all the 22 population were sub-grouped into three groups. Interestingly, north and west Indian population showed high genetic similarity and assembled into one cluster in cluster analysis. The east and south Indian populations were evenly segregated into rest two clusters. Similarly, north and west Indian population again deemed to be occupied same compartment in Principal coordinate analysis (PCoA). This variation might be associated with the N. lugens migration due to wind movement of south-west monsoon in two branches viz. Arabian sea branch and Bay of Bengal branch. Present study provides the molecular evidence of population genetics of N. lugens in India and the information could be useful to devise the efficient management strategy against this pest in different rice ecosystem.

“…When nymphs feed on plants infected by stunt viruses, they can transmit the viruses just like macropterous or brachypterous imago. Tyagi et al (2022) reported short distance distribution of brown planthopper in a plantation is performed by the nymphs, brachypterous, or macropterous imago. Short-distance distribution between plantation and long-distance distribution are performed by the macropterous imago.…”

Abstract. Listihani L, Yuniti IGAD, Ariati PEP, Pandawani NP, Selangga DGW, Temaja IGRM, Wirya GNAS, Sudiarta IP. 2023. Beneficial interaction between rice stunt virus and its insect vector Nilaparvata lugens Stal based on life table. Biodiversitas 24: 4690-4698. The brown planthopper (Nilaparvata lugens) causes direct and indirect damage as a stunting virus vector in rice. Insect vectors and viruses are closely related with respect to disease transmission to host plants. Thus, this research aimed to determine the specific relationship between a virus and its insect vector on the biology and demography statistics of viruliferous brown planthopper (BPH). Research method included the propagation of N. lugens and stunt virus inoculum, the observation of cohort, stadia duration and egg survival rates, imago life span, and N. lugens life table. The BPH life table was arranged with the jackknife method for two treatments: plants infected by stunt virus and healthy plants. The research result showed that plants infected by stunt virus can shorten the BPH nymphal development stage from instar 2 to instar 5, life cycle, preoviposition period, and double time. Plants infected by stunt virus did not influence the BPH hatching pattern but influenced the total number of hatching eggs. The next BPH generation of stunt virus inflected plants increased 29.51 times more from the previous generation, while on healthy plants, the next BPH generation only increased 27.51 times. Virus-infected plants generally appeared to be superior quality hosts for vectors compared to uninfected plants, thus enhancing vector life table and virus spread.

“…Molecular evidence has been extensively used to trace the evolutionary and colonization history of animals and plants (5,25,26). Previous molecular-level studies on BPH migration based on either scattered markers or incomplete sampling could not yield enough resolution to completely differentiate BPH populations (27)(28)(29)(30). In this study, we sampled worldwide BPH populations for wholegenome sequencing and pioneer to genetically track their migratory routes.…”

Many insect pests, including the brown planthopper (BPH), undergo windborne migration that is challenging to observe and track. It remains controversial about their migration patterns and largely unknown regarding the underlying genetic basis. By analyzing 360 whole genomes from around the globe, we clarify the genetic sources of worldwide BPHs and illuminate a landscape of BPH migration showing that East Asian populations perform closed-circuit journeys between Indochina and the Far East, while populations of Malay Archipelago and South Asia undergo one-way migration to Indochina. We further find round-trip migration accelerates population differentiation, with highly diverged regions enriching in a gene desert chromosome that is simultaneously the speciation hotspot between BPH and related species. This study not only shows the power of applying genomic approaches to demystify the migration in windborne migrants but also enhances our understanding of how seasonal movements affect speciation and evolution in insects.
