A field study was conducted at the Agriculture Experimental Farm of EI- Nobaria Research Station, EI-Behaira Governorate, in seasons of 2005 and 2006. Two chemical compounds were evaluated for controlling the leaf miners and spider mites on cantaloupe plants, i.e, thiamethoxam (Actara ®, and pymetrozine (Chess ® , besides two plant natural products azadirachtin (Achook® and soybean oil (Natural oil ®) . In seasons 2005 and 2006, most of the evaluated compounds were found to have a comparative less toxic effect against the leaf miners. Azadirachtin was relatively the efficient against the treated insect -pest (73.67 % at the 7th day with an average rate of reduction comprised 56.54 %) followed by the other tested compounds: soybean (Natural oil ®') 10 pymetrozine (Chess® and the least effective one thiamethoxam (Actara). The less efficient compounds thiamethoxam (Actara® and soybean oil (Natural oil ®) gave the same rate of reduction (38.39 and 37.88 %), respectively. Also for both the inspected spider mites Tetranychus urticae (Koch) and Tetranychus cinabarinus (Boisd)in seasons 2005&2006, soybean oil ( Natural oil ® ) was found to be the most effective compound among aI/ the performed treatments followed by Azadirachtin ( Achook®) and the less efficient thiamethoxam (Actara®) and pymetrozine (Chess®).
