Efficacy of insecticides' applications against the cereal leafminer Syringopais temperatella Led. (Lep., Scythrididae) on barley under field conditions in Karak – Jordan
Dirasat, Agricultural Sciences 39: 65-74.
The cereal leafminer, Syringopais temperatella Led. (Lep., Scythrididae) is considered one of the major insect pests of wheat and barley, and causing significant damage in Jordan. Nevertheless, this study aimed at investigating the effect of insecticide type, time and number of applications against S. temperatella on barley under field conditions in Karak-Jordan. Six different insecticides were used to find their effect on this destructive pest. Results in early spray indicated that diazinon caused significantly the highest mortality to S. temperatella, while the lowest mortality was recorded for imidacloprid. In twice sprays, diazinon, chlorpyrifos and fenitrothion caused mortality of 100%. In conclusion, the current study indicated that organophosphate insecticides are more toxic to the pest than the other insecticides. In addition, the pest mortality was higher and infestation was lower when the plants were sprayed twice rather than once.
