Field Exploration of the Efficacy of Some Friendly Products in Combination with Some Pesticides against the Red Palm Weevil <i>Rhynchophorus ferrugineus</i> (Olivier) (Coleoptera: Curculionidae) and Its Effect on Total Carbohydrates and Micronutrients in the Resulting Date Fruits

Experiments were carried out against the red palm weevil, Rhynchophorus ferrugineus (Oliv.) (RPW in a private orchard containing varieties of Samani (domestic) and Ikhlas (imported) infested with weevil (RPW) El-Marg area, Cairo Governorate, Egypt, using Petroleum oil, Jojoba Inorganic salts, singly mixed each insecticides (Acetamiprid, Profenofos, Dimethoate) by injection spraying trunks, as well pouring these substances into pits around roots affected trees. The data showed that Acetamiprid was most effective RPW. mixtures R. Jujuba oil Acetamiprid, also used car inorganic which resulted 100% recovery treated palm. Continuing treatment palms for 6 consecutive months injecting saline solution both date cultivars. Spraying on trunks had no effect Pouring tested solutions least Injection pesticides increased concentrations carbohydrates total micronutrients (Fe+, Mn+, Zn+, Cu+) produced fruits more than those obtained mineral oils salt, compared to control group. There is significant difference between treatments.
