Rice stem nematode Ditylenchus angustus development and survival

摘要

The plant parasitic nematode Ditylenchus angustus is an important pest of both deepwater and lowland rice, A research program, funded by the Levelhulme Trust, has been undertaken to investigate the population dynamics, development, and survival of D,angustus under controlled experimental conditions. Infectivity studies demonstrated that third (J3) and fourth (J4)- stage juveniles and adults were able to infect IR36 rice seedlings in pot cultures kept under lowland growing conditions. Second-stage juveniles (J2) molt rapidly to J3. It may only be J3, J4, and adults that invade.
