Control of Liriomyza spp in broad bean crop in Garbia Governorate, Egypt

Abstract: Recently, the yield of the broad bean, Vicia fabe, L was greatly reduced owing to the control of the leafminers Liriomyza spp (Diptera, Agromyzidae). Most species of leafminer flies have developed resistant to products that were originally effective. The use of more selective materials such as Protecto, Bactospein (a Bacillus thuringiensis compounds) and Spinosad as microbial control agents are recommended as it allow survival of the leafminer parasitoids. Also, the chemical insecticide Malathion and the mineral oil Capl 1 were evaluated against this insect pest. As the insect was affecting the bean foliage through puncture the leaves for feeding and oviposition, defoliating its compound leaves and the petioles dry out reducing its photosynthetic activity, alternatively reducing average weight and number of green pods. The highest number of compound leaves and petioles, thereby the highest average number with the highest weight of green bean pods were recorded for the Malathion treatment, followed by Spinosad, Capl 1, the Bt compounds and lately the control. Malafhion and Spinosad treatments recorded minimum infestation thereby the highest yield (8.13 and 7.9) ardab/faddan and the yield increased by (39.93 and 35.97516) respectively, followed by Capl 1 where the yield recorded (7.16) ardab with a percentage 23.24 of yield increased. The yield of both Bactospein and Protecto treatments were relatively low (6.47 and 6.61) with an increase in yield of (16 and 13.77Yo) respectively. The control recorded the highest infestation and the lowest yield (5.81) ardab/faddan. So, the leafminers could be successfully controlled using either of Malathion, Spinosad or the mineral oil. The bean yield increased significantly through applying the different control measures.
