Panicle Rice Mite (PRM) is the most destructive mite pest attacking rice Oryza sativa (L.) in the Caribbean, Asia and Central America. Schoenoplectus articulates (L.), and the wild rice, Oryza latifolia Desv., were recorded as alternate hosts of PRM in some countries. A survey was conducted to identify alternate hosts of PRM in Sri Lanka and the observations were confirmed by transmission test. Of the 675 weed plants, consisting of 475 grasses and 200 sedges, observed for PRM, Sacciolepis interrupta, Echinocloa crus-galli and Leptochloa chinensis were determined as alternate hosts of PRM. The transmission tests conducted with common rice associated weeds namely, Cyperus rotundus (L.), C. kyllingia Endl., C. iria (L.), Leptochloa chinensis (L.), Echinocloa crus-galli (L.), Paspalum scrobiculatum (L.), Imperata cylindrica (L.), Sacciolepis interrupta (Willd.) and 5 wild rice species (Oryza nivara, O. echinigery, O. rufipogon, O. granulata and O. rizomatis) revealed that, O. nivara, S. interrupta, E. crus-galli and L. chinensis facilitate the survival and oviposition of PRM. In addition, O. nivara, S. interrupta found to be highly susceptible to PRM than E. crus-galli and L. chinensis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
