Abstract
These experiments were conducted under field conditions on Pea, Pisum sativum L. plants along two seasons (2019 - 2020) and (2020 - 2021) to investigate the effect of climatic factors, potassium silicate as a fertilizer and sowing dates on aphid numbers. Pea seeds were sown at El-Qanater Research Station Farm in Qalubiya Governorate, Egypt. The obtained results revealed that Pea aphid, Acyrthosiphon pisum Harris is the major insect pest of Pisum sativum L., the highest numbers were recorded in mid-September followed by 1 October and 1 November. Aphid populations peaked at different times during the two years of the study. The highest populations occurred during the mid-September planting date in the two seasons recording 155, and 220 individuals per plant, respectively. Pea aphid population dynamics were affected by weather conditions. The number of aphids significantly and positively correlated with maximum temperature, but were significantly and negatively correlated with relative humidity. The effect of minimum temperatures on pea aphids was non-significant where the correlation was negative. Pea aphid infestation resulted in losses of total seed weight for pea plants. Using Potassium silicate as a foliar spray decreased A. pisum population, as well as enhanced the crop resistance to biotic and abiotic stresses. Spraying potassium silicate on pea plants reduced the target pest population by 45 to 64 % along the two seasons of study. Potassium silicate could be listed in the integrated pest management program of pea plants to keep the aphid population under control. The planting date of October as well as potassium silicate spraying gave the highest yield of pea pods in both growing seasons.
