| Abstract | ||
| Population fluctuation of the green peach aphid were conducted at Assiut area. Results showed that the activity of the green peach aphid was first recorded on 22 December 2016 and 2017 (3.24 and 6.20 aphids / plant) and reached its peaks during the first week of February and last week of January (33.62 and 48.76 aphids / plant) toward bud and flowering stages. Population model using the meteorological data indicated that plant age and parasitoids were important biotic factors in the population development of M. persicae, followed by minimum air temperature and maximum relative humidity. | ||
