Laboratory experiments showed that the mixture of inorganic salts with mineral oil is effective against 4th larval instar of the red palm weevil, Rhynchophorus ferrugineus (RPW). Light trap data showed that insects which help in the spread of R.Ferrugineus in palm groves, they appear during the months of February and March. Its peak recorded from May until September. The neglected palm orchards are more susceptible to insect infestation with RPW than those that receive agricultural and pest control services. Field experiments in Nubariya and EL-Marg regions showed that injecting palms with a triple mixture consisting of motor oil—jojoba oil and a solution of inorganic salts at a rate of 1 liter of each substance (which are the components of the natural composition) to treat both two varieties Samani and Ikhlas, as well as the two varieties (Barhi and Zaghloul) of the infected palms) by injecting the natural composition for 6 consecutive months at a rate of 100 cm/infected palm, the treated palm trees recovered by 100% from infection with RPW.
