Abstract

The results revealed a reduction of 23.74 and 33.45 per cent in adult emergence of braconid parasitoid of T. theae when highest dose of profenofos @ 1000 g a.i. ha−1 was applied in the two field experiments, respectively. Profenofos at recommended dose (500 g a.i. ha−1) caused a mean reduction of 16.36 and 19.46 per cent in parasitoid emergence with respect to control in first and second field trials, respectively.
