Abstract:
The investigation was conducted to study the biologyof Sitotroga cerealellaOlivieron stored wheat, Triticum aestivum L. in the laboratory of the Department of Entomology, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, India, during 2021-22at 30.25 ± 0.25 ºC temperature and 75.00 ± 5.06% relative humidity. The mean oviposition, incubation and larval-pupal period of S. cerealella were 3.5 ± 0.61, 4.2 ± 1.01 and 26.7 ± 1.38 days, respectively. The male and female longevity were 10.25 ± 0.97 and 7.60 ± 0.75 days, respectively. The average length and breadth of eggs were 0.61 ± 0.05 and 0.31 ± 0.02 mm, respectively. The average length and breadth (across the wings expanded) of male were 3.82 ± 0.26 and 7.70 ± 0.31 mm, respectively, whereas, the female moth measured on an average 4.25 ± 0.26 mm in length and 9.61 ± 0.46 mm in breadth. The mean total life cycle of male and female of S. cerealella was 38.5 ± 1.79 and 41.15 ± 1.87 days, respectively.
