摘要

Studies were conducted to investigate the seasonal activities of larval parasitoid C. plutellae on the larvae of P. xylostella in cabbage crop. The activities of C. plutellae were on the peak during 11th and 10th standard meteorological weeks in 2000-01 and 2001-02 with 47.2 and 47.3 per cent larval parasitisation, respectively. The larval parasitoid showed a positive correlation with the host larval population in both the years.
