“…Cycles of rapid population growth and further north and north-eastward migration eventually spread N. lugens as far as northern China, Korea and Japan (Cheng et al, 1979;Kisimoto, 1987;Watanabe et al, 1991;Sogawa & Watanabe, 1992). In the autumn, there is circumstantial evidence of several waves of N. lugens migration in a generally southward or south-westward direction (Cheng et al, 1979;Kisimoto, 1987;Rosenberg & Magor, 1987;Pender, 1994). The risk of N. lugens outbreaks in any locality is thus dependent in part on the intensity and timing of immigration, which in turn depends on populations in distant source areas.…”

Radar, aerial netting and ground sampling were used to study the autumn migration of Nilaparvata lugens (Stal) in Jiangsu Province in east central China. Emigration of macropterous adults increased from late August until late September as the main rice crop matured and was harvested. In early and mid September, the resulting windborne migrations carried the planthoppers mainly towards the west, although the migration directions ranged (within the western sector) from south to north. By late September, however, displacements were predominantly to the south-west on the then prevailing north-east monsoon winds: migration was particularly rapid when the north-easterlies were reinforced by typhoons. Although in late September such movements to more southerly latitudes are essential for the survival of the planthoppers' progeny, we found no definite evidence for preferential emigration on winds blowing towards the south. There were, however, indications that when winds towards the north occurred, the duration of migratory flight was curtailed. Irrespective of any possible preference for migration on northerlies, a large proportion of the N. lugens population would normally be carried in an adaptive southwards direction, because the advent of the north-east monsoon occurs at a time when the number of flight-ready planthoppers approaches its peak.

“…In China, the insect migrates from the south to the rice-producing regions in the middle and lower reaches of the Yangtze River in the summer, where it has three to four generations per year (Cheng et al 1979). In the autumn, the N. lugens population migrates southward to the overwintering area, where it feeds on the available rice plants (Cheng et al 1979;Kisimoto 1987;Rosenberg and Magor 1987;Pender 1994;Riley et al 1994). When the density of N. lugens is high, feeding leads to hopperburn (blocking of phloem sieve tubes), which is reflected by the drying of rice leaves and the wilting of the tillers (Bae and Pathak 1970).…”

2011) Proportional transfer of chemical elements from rice plants to rice brown planthopper (Nilaparvata lugens [Stål], Hemiptera: Delphacidae) and its honeydew, International Journal of Pest Management, 57:3, 169-175To link to this article: http://dx.The chemical elements Fe, Mg, Cu, Zn, and Mn are involved in the various physiological processes of plants. A change in the contents of some chemical elements in rice (Oryza sativa L.) plants is associated with resistance to pests; this includes the slow growth of rice brown planthopper (Nilaparvata lugens Sta˚l) populations. By manipulating the concentrations of Zn, Mn, Fe, and Cu in a hydroponic solution, we tracked the flow of these elements from a hydroponic solution through the rice plant phloem sap, to planthoppers, and ultimately the honeydew excreted by N. lugens. The results showed not only that the contents of Zn, Mn, Fe, and Cu in the rice plants increased with their concentrations in the hydroponic solution but also that the increase in the levels of these four elements in the hydroponic solution affected the level (positively or negatively) of other chemical elements in the rice plants. Furthermore, some of the changes in element levels in the rice plants were reflected in the content of the phloem sap, N. lugens itself and its honeydew. Among the four chemical elements manipulated in the hydroponic solution, only elevated levels of Mn and Na were proportionally transferred to both the rice plants and N. lugens. Therefore, those particular elements could be used as markers to match N. lugens individuals to the rice plants on which they have fed. Our findings have potential applications for determining the provenance of N. lugens migratory populations by examining the levels of chemical elements in N. lugens immigrants, which would lead to a better understanding of the migration sources and routes of this insect.
