Nupserha bicolor Thoms., subsp. Postbrunnea Breun.: a New Pest on Jute (Corchorus olitorius Linn.)


DAS1 recently compiled a list of insect and mite pests of the two cultivated species of jute, namely, Corchorus capsularis and Corchorus olitorius. A pest, hitherto unrecorded in India, was detected in olitorius jute during 1949 on the farm of the Jute Agricultural Research Institute, and was identified by the Commonwealth Institute of Entomology, London, as Nupserha bicolor Thoms., subsp. postbrunnea Breun. The pest has since been found to be an important one for all the varieties of C. olitorius, while the capsularis varieties show resistance to it.
