Abstract

The present work was conducted during the successive growing seasons of 2022/2023 and 2023/2024 at the Experimental Farm of Shandweel Agricultural Research Station,in Sohag Governorate, Egypt to estimate the influence of foliar spray applications with salicylic acid(SA) and methyl salicylate(MS) on pea infestation Aphis.craccivora and Acyrthosiphon. pisum infesting three pea cultivars and their associated main predators (Coccinella undecimpunctata and Chrysoperla carnea). Data revealed that pea cultivars varied significantly in the infestation of pea plants by the aphid species, however, no significant differences were found in the case of insect predators. The pea infestation with the two aphid species was significantly reduced in SA and MS treatments compared to the control during the two growing seasons. Data revealed that MS showed a great effect on the two previous insect predators in both seasons, however, no effect was observed in the case of SA.
