Abstract
Survey insect pests associated with maize plants at Beni-Suef and Al Qalubia Governorates during the growing season of 2022. Results revealed the occurrence of twelve insect pest species belonging to four orders and seven families. The fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) is a new invasive destructive insect pest. It was first recorded at Beni-Suef and Al Qalubia Governorates in this study on maize fields in 2022. The population density of S. frugiperda fluctuated with four distinct peaks (the highest peak was in December) in the two Governorates. The combined effect of max., min. temperatures and relative humidity were highly significant for this pest in the two Governorates. Using bio-pesticide (Bacillus thuringiensis) resulting in decreasing the infestation of S. frugiperda by 64.8 % and 75.3% in the field in the two Governorates, respectively. This information and prediction could be helpful to proper integrated control management.
