Abstract
The studies were conducted at Chhindawara Forest circle to find out the relationship of weather parameters on the activity and infestation of Hyblaea puera Cramer on teak seedlings. During 1999-2000 mean percent incidence and population of teak defoliator, H. puera, ranged respectively, between 3.69% to 19.20% and 2.35 larvae per quadrate to 13.07 larvae per quadrate. Infestation started from 23rd SMW to 35th SMW. It was at maximum in 26th SMW. It disappeared after 35th SMW. In 2000-2001, H. puera infestation ranged from 3.28% to 20.93%. It initiated from 23rd SMW, gained its maximum in 26th SMW and continued till 35th SMW. The incidence and population of the larvae showed trends related to the meteorological parameters, but the correlation coefficient of incidence and population of H. puera Cramer, vs maximum, minimum temperature and relative humidity of the corresponding period was found statistically non-significant during both the years.
