Abstract

The present study was carried out at the experimental farm of Sakha Agricultural Research Station, Kafr El-Sheikh Governorate during two successive seasons, 2011/12 and 2012/13 to evaluate the influence of some conventional (Malathion extra or Max Sped) and non-conventional insecticides on the main insect pests attacking faba bean plants.
The conventional insecticide Malathion-Extra exhibited a high efficiency against Aphis craccivora (Koch.) population with the highest average percentage of reduction (86.26 ±7.64 % and 94.34±2.85 %) followed by Capel 2 (72.13 ±6.20 % and 79.69±5.75 %) during the two seasons; 2011/12 and 2012/13, respectively.
The conventional insecticide Malathion-Extra exhibited a high efficiency against Empoasca spp. population with the highest average percentage of reduction (51.52±11.19 % and 58.83±5.45 %) followed by Capel 2 (40.88±10.14% and 54.09±7.50 %) during the two seasons, respectively.
The conventional insecticide Max Sped exhibited a high efficiency against Liriomyza trifolii (Burgess) larval population with the highest average percentage of reduction (75.97±10.52 % and 67.25±13.94 %) followed by Capel 2 in the first season (75.63± 4.19 %) and Bioguard in the second one (57.10±12.15%).
The statistical analysis revealed significant differences among average percentages of reduction of aforementioned insect pests and the used compounds during the two successive seasons.
