Abstract

Faba bean Vicia faba L. is one of a major grain legume consumed worldwide for its edible seeds and pods. Faba bean is not important cash crop only, but also is considered as a promising crop, which adapts to climate change hence feed future generation due to its high protein content. Aphis craccivora ( Homoptera : Aphididae ) is perennial pest of leguminous crops. The important pest in faba bean is aphid, Aphis craccivora in Egypt, which are found to suck sap cells by sucking and piericing mouth parts as well as transmit serious viruses causing great damages. The field experiment was carried out to determine the occurrence of A. craccivora attack faba bean, Vicia faba L. plants during 2021 &2022 seasons. All treatments were arranged in randomized complete design. The present study was carried out in the field to evaluate the toxic effects of Faba bean seed treatments by camphor, mint, basil oils and Gaucho (Imidacloprid) on A.craccivora,  followed by the same treatment after four weeks , as well as on the foliage characters of the plants . Date indicted that the highest reduction percentage in seeds treatments was recorded with Imidacloprid 84.17,78.54 and 72.75 % followed by mint oil with 81.27,77.35 and 69.57 % 2.3 and 4 weeks of planting date, respectively in 2021 and with 89.53,83.99 and 80.85 % in Imidacloprid followed by 83.52,80.09 and 75.59 % in mint oil, respectively in 2022 season. Regarding to the effect of foliar treatments, of Camphor oil, basil oil, mint oil and Imidacloprid on mean numbers of Aphid, it recorded 17.25, 19.95, 17.60 and 12.13 aphids/ 10 leaves, respectively comparing with 222.90 aphids/ 10 leaves in control in 2021 season, and 13.05, 14.43, 13.85 and 10.05, respectively comparing with 192.95 aphids/ 10 leaves in control in 2022 season. Data indicated that both of insecticide and the botanical oils reduced aphid numbers in the field. It could be reported that the tested essential oils can used as a natural insecticides for the control of the aphid to protect our environment from bad effects of chemical pesticides.
