A study was conducted for three successive seasons (2014-17) to evaluate the effect of dibbling
time on population dynamics of onion thrips (Thrips tabaci) on garlic dibbled on ten different dates
starting from 1st September to 15th January at fortnight interval. The significant difference was observed
in thrips population load among the dibbling dates. The garlic dibbled on early-December had maximum
thrips load (41.8 thrips/plant) followed by both early and late-November sown crop (40 thrips/plant). The
least mean of thrips population recorded with early-September planted garlic. Irrespective of sowing
dates, highest thrips population peaks were recorded during 1st to 6th Standard Meteorological Week
(SMW ) of January and February. The maximum average of 59 thrips/plant were registered during early
February (5th SMW). The dry spell coupled with optimum temperature (Tmax= 29 to 33°C and Tmin= 9 to
14 °C) favoured thrips population build-up. The correlation analysis between thrips incidence and weather
parameters showed significant negative correlation between thrips population and temperature as well
as with precipitation.
