Abstract :
The current study was conducted to investigate strength and durability of the effect of three widely used insecticides against mango leafhopper (MLH), Idioscopus clypealis (Lethierry) (Hemiptera: Cicadellidae) in two different methods (foliar spray and trunk injection) in Roodan district (Hormozgan province). The study was performed as factorial arranged in a Randomized Complete Block design (RCB). In all sampling sessions (3, 7, 15 and 30 d post applications), the number of nymphs decreased significantly on the inflorescence, indicating insecticides used in both methods were able to suppress MLH, relatively. Although the insecticides showed no significant difference in foliar application, they were significantly different when injected through the trunk (F=8.85; df=2; P
