Migration Prediction and Monitoring of Rice Planthoppers in Japan
This paper presents a new method of migration prediction for rice planthoppers. Using this new method, a three-dimensional backward trajectory analysis was conducted to find migration sources of rice planthoppers that immigrated into Japan. The results showed that the coastal regions of Fujian province in China and Taiwan were possible sources of the whitebacked planthopper (WBPH) that immigrat...
متن کاملMigration of rice planthoppers and their vectored re-emerging and novel rice viruses in East Asia
This review examines recent studies of the migration of three rice planthoppers, Laodelphax striatellus, Sogatella furcifera, and Nilaparvata lugens, in East Asia. Laodelphax striatellus has recently broken out in Jiangsu province, eastern China. The population density in the province started to increase in the early 2000s and peaked in 2004. In 2005, Rice stripe virus (RSV) viruliferous rate o...

Four species of planthoppers were collected using net traps and an aspirator on a weather ship above the Pacific Ocean, An entornegenous fungus, thynia delphacis (Entomophthorales), was isolated from a specimen of the whitebacked rice planthoppeT, Sogatetla jurcijlera. The fungal isolate was infectious to 3 species of planthoppers, Sogatella.fttrcijbra, Nitaparvata lugens, Laocteiphax striatelt...
متن کاملVirus altered rice attractiveness to planthoppers is mediated by volatiles and related to virus titre and expression of defence and volatile-biosynthesis genes
Viruses may induce changes in plant hosts and vectors to enhance their transmission. The white-backed planthopper (WBPH) and brown planthopper (BPH) are vectors of Southern rice black-streaked dwarf virus (SRBSDV) and Rice ragged stunt virus (RRSV), respectively, which cause serious rice diseases. We herein describe the effects of SRBSDV and RRSV infections on host-selection behaviour of vector...
متن کاملParasitism and predation of the planthopper Tagosodes orizicolus (Homoptera: Delphacidae) by a dryinid parasitoid in Costa Rica
We analyzed the effect of predation and parasitism by the native dryinid Haplogonatopus hernandezae as a natural enemy of the rice pest Tagosodes orizicolus under controlled conditions in an insectary in Costa Rica. We found no change in the proportion of T. orizicolus nymphs that were fed upon, parasitized, and that showed no apparent damage throughout the adult stage in H. hernandezae, which ...
