EVALUATION OF SOME INSECTICIDES ON INFESTATION OF RED PALM WEEVIL Rhynchophorus ferrugineus (OLIVIER) (COLEOPTERA: CURCULIONIDAE)

Abstract

The present work was carried out at El-Katta village to evaluate the efficiency of six synthetic insecticides (Pyriban ® , keiton ® , Egycron, Fenthion ® , Fury ® , and Regent ® ) and two bio-insecticide (Biovar ® (Beauveria bassiana) and Avermectin ® (emamectin benzoate)). Insecticide solutions were injected into three holes against the immature stages of Red Palm Weevil (RPW), Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae). Three concentrations of each tested insecticides (0.3%, 0.6 and 0.9%) were used. The insecticides were applied at rate of one liter per tree. The numbers of recovery palm trees were investigated every week and recorded after forty five days from treatment. The obtained results showed that the most effective insecticide was Pyriban ® and Keiton ® (62.5%), followed by Egycron ® (58.3%), Fenthion ® (37.5%), Fury ® (29%), and Reagent ® (25%). The bioagents were less effective than synthetic insecticides; Biovar ® (12.5%) and Avermectin ® (4.1%) at 0.3% concentration.

Biochemical and Histological Responses of Red Palm Weevil, Rhynchophorus ferrugineus Exposed to Sub-lethal Levels of Different Insecticide Classes

“…But RPW developed resistance against used insecticides and phosphine fumigants which is considered a serious concern (Wakil et al, 2018). So lately, biologically based synthetic insecticides are applied as a curative insecticide against R. ferrugineus in date palm (Abdel-Salam et al, 2014;Mashal and Obeidat, 2019). The spinosad (spinosyns) is a natural and active insecticide derived from the rare soil-dwelling actinomycete bacterium called Saccharopolyspora spinosad (Mertz and Yao, 1990).…”

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

“…As for the average % recovery from infestation after treatment against the red palm weevil, it was 72.9 ± 19.3 for the Ekhlas variety, higher than for the Samani variety, where the average % recovery amounted to about 66.7 ± 25. 6 Injection the mixture of used car oil with a solution of inorganic salts, as well as the mixture of used car oil with Acetamiprid, led to100% recovery of the treated varieties (Samani and Ikhlas) from insect infestation, whereas, injection of used car oil mixture of Profenofos into the infested trunk of palms (Samani and Ekhlas cultivars) resulted in 75% recovery of treated palm trees.…”

“…), and it turns out that the most effective against the insect were Pyriban ® and Keiton ® (62.5%), followed by Egycron ® (58.3%), Fentthion ® (37.5%), Fury ® (29%) and Reagent ® (25%). While the biocomplexes were less effective than synthetic insecticides, Biovar ® (12.5%) and Avermectin ® (4.1%) at a concentration of 0.3% [6]. Several researchers have contributed to suppressing the severity of the red palm weevil using biochemicals [7].…”
