Abstract
Field and poly house experiments were conducted to evaluate the new insecticides for the management of
mite, Polyphagotarsonemus latus Banks on capsicum. Among the seven insecticides, mean of two seasons under
field conditions reveal that, post count population was lower with spiromesifen (0.62 mites leaf-1) followed by
diafenthiuron (4.08 mites leaf-1), triazophos (5.73 mites leaf-1) and thiamethoxam (9.43 mites leaf-1) which were
superior over rest of the treatments and untreated check (17.60 mites leaf-1). Under poly house condition, population
was less with spiromesifen (0.06 mites leaf-1) followed by diafenthiuron (2.21 mites leaf-1), triazophos (3.68 mites leaf-
1) and thiamethoxam (5.30 mites leaf-1) which were superior over untreated check (11.33).Comparision of efficacy of
insecticides, there was significant difference in percent reduction of population over untreated check after each spray.
The percent reduction and mortality in mite population were high in poly house (spiromesifen, flubendiamide and
spinosad) compared to open field.
