“…Rice planthoppers are long-distance migratory species. BPH and WBPH cannot overwinter in northeastern Asian countries, including Japan, Korea and Northern China, and annually migrate there from lower latitude regions in May, June and July (Kisimoto 1976;Hirao and Ito 1980). WBPHs stylopized by E. japonicus were captured in the East China Sea (Noda 1986;Kifune and Maeta 1986), which indicates that Elenchus also migrates for long distances with the host planthopper every year.…”

The twisted-wing parasite Elenchus japonicus is a major parasitoid of rice planthoppers (Hemiptera: Delphacidae), including the brown planthopper Nilaparvata lugens, the white-backed planthopper Sogatella furcifera, and the small brown planthopper Laodelphax striatellus. Another Elenchus species, E. yasumatsui, which is considered to be synonymous with E. japonicus, has also been described in southern Asia. However, limited biological and molecular data on this important parasitoid of rice planthoppers are available. In this study, E. japonicasstylopized planthoppers were obtained from various regions in Asia and Japan. Sequences of the nuclear 18S ribosomal RNA gene and the mitochondrial cytochrome oxidase I gene of the strepsipterans were analyzed from 40 samples of E. japonicus: 14 from N. lugens, 6 from S. furcifera and 20 from L. striatellus. Sequence analysis of these samples revealed three genotypes of E. japonicus. Of the three types of E. japonicus, one was isolated only from L. striatellus from northern Japan. The other two types were found in all three rice planthopper species collected from a wide area in Asia. These results suggest that the three different genotypes of Elenchus can be associated with a particular geographical region and/or planthopper species. The relationship between two previously described Elenchus species and the present three genotypes needs to be elucidated.

Rice planthoppers are major pest for rice plants in Asian countries. They immigrates from overseas to Kyushu in Japan in the Baiu season every year. To predict the long distance migration of rice planthoppers to northern Kyushu, a migration model was developed with a hypothesis that rice planthoppers were transported by low-level jet stream at 1,000-2,000 m heights. The weather conditions for the migration period (June to July) were analyzed with the 850 mb chart at 21 h in 1980-1985 and at 09 h and 21 h in 1986, and possible migration days were decided. On the other hand, actual migration flight waves were decided with the number of catches by two nets. The possible migration flights decided by the weather chart agreed approximately with the actual flights. The accuracy of this prediction method was improved by using the 850 mb chart at 09 h additionaly. Finally, the prediction procedure was described.

“…Males of S. furcifera, however, are exclusively macropterous. Neither of these species is able to overwinter successfully in Japan and colonisation occurs annually following long-distance migration from southern China (Kisimoto, 1976). Although the two species occur simultaneously in paddy fields following colonisation by macropterous immigrants, their population growth patterns differ.…”

Abstract. 1. A series of laboratory experiments was conducted to explore the effects of inter-specific interactions, both direct interactive effects and those induced through previous feeding, on the dispersal capability (proportion of macropterous adults) and performance (development time and survival) of two wing-dimorphic planthoppers, the whitebacked planthopper Sogatella furcifera and the brown planthopper Nilaparvata lugens, two pests of rice throughout Asia.2. An asymmetric effect of inter-specific crowding on dispersal capability was detected between the two planthoppers. With density controlled, the proportion of macropterous adults in N. lugens was higher when raised in mixed populations with S. furcifera than in pure cultures comprised of conspecifics, suggesting that interspecific effects on dispersal capability are stronger than intraspecific effects. In contrast, interspecific effects on macroptery (%) were weaker than intraspecific impacts for S. furcifera.3. This trend was parallelled by adverse competitive effects on survival, with interspecific effects stronger than intraspecific impacts for N. lugens and intraspecific effects stronger for S. furcifera.4. Crowding also affected the incidence of macroptery indirectly through feedinginduced changes in plant physiology. Rearing N. lugens on plants fed on previously by heterospecifics resulted in a higher incidence of macroptery in females and protracted development than for N. lugens raised on plants fed on previously by conspecifics. By contrast, the intraspecific effect of previous feeding was stronger than the interspecific effect in S. furcifera, with higher macropter production and prolonged development occurring on plants exposed previously to conspecifics.5. The results suggest that interspecific interactions between herbivorous insects, both direct and via feeding-induced changes in plant physiology, can have negative consequences for performance and survival and promote the production of flight-capable adults that can disperse.

Abstract: out of thirty-eight originating in the central part of the Chinese continent, caused immigrations. Yearly fluctuations of planthopper infestations in Japan were shown to depend on the yearly fluctuations of the route of depressions associated with the migration of the planthoppers.
