Abstract:
Effect of integrated management approach was studied for combating angoumois grain moth. Sitotroga
cerealella (Olivier) at different generation in terms of adult emergence, adult longevity and population
ratio during the period from March 2011 to September. 2011 in the Department of Entomology. Sher-eBangia
Agricultural University. Dhaka. Bangladesh. The treatments of the studies were: Cleanliness of
the storage including the container and premises (sanitation) + Use of dried neem kamel powder @ 10
gmJkg (T,); Cleanliness of the storage including the container and premises (sanitation) + Use of dried
tobacco leaves powder @ 5.0 gmJkg (T2); Sanitation + use of insecticide in the empty bins as preventative
measure + Use of dried neem kamel powder @ 10 gmJkg (T); Sanitation + use of insecticide in the
empty bins as preventative measure + Use of dried tobacco leaves powder @ 5.0 gmlkg (T,); Sanitation
+ Release of Trichogramma evanescense after 30 days interval (number of Trichogramma = lOO/plastic
container or replication (Ts): Sanitation + Application of fumigant practice with phosphine gas with doses
depending on the temperature and humidity and the pest population (To) and Untreated control (T,). The
study was laid out in a Completely Randomized Design (CRD) with four replications. In I" generation no
adults emerged in To treatment which was followed by T, (9.67) whereas the highest (38.00) adult was
recorded in T, (untreated control) treatment. Similar trend of adult emergence was observed in 2""
generation and 3'd generation of the pest. In I" generation no adult longevity was recorded in To treatment
whereas the highest (10.00 days) adult longevity was recorded in T, treatment. Statistically significant
variation was recorded for number of female. male and their ratio for I st. 2"" and 3'd generation of
angoumois grain moth in stored rice grain due to integrated management approaches.
