Efficacy of chemical, biological insecticides and plant extracts against red palm weevil Rhynchophorus ferrugineus (Curculionidae : Coleoptera)‎ under laboratory and field conditions

الملخص EN

The red palm weevil Rhynchophorus ferrugineus (Olivier) (Curculionidae : Coleoptera) is the most serious insect pest of cultivated palm trees in several date palm producing countries.

The laboratory study was carried out during year 2020 in Research Laboratory of Red Palm Weevil, Plant Protection Research Institute.

Field experiments were carried out at date palm farm of area 10 feddan planted with barhi date palm variety, at the Regional Research Station for Delta East, Qassasin, Ismailia Governorate, Egypt.

The aim of research work is to evaluate the efficiency of different group of insecticides; chemical (Profenomex 44% EC), biological (Bio- Magic 1.15 WP) and plant extracts (Palmotto 60% EC) to control this insect under Laboratory and field conditions.

Results indicated that the efficiency of tested insecticides varied considerably due to the chemical nature of testing insecticides and the concentrations used.

Profenomex 44% EC proved to be the most effective compound followed by palmotto 60% EC and bio-magic 1.15% WP , respectively.

Evaluation of the efficiency of certain insecticides to control this pest in field by injection palms, the results shown that profenomex 44% EC proved to be more effective against red palm weevil with low concentration compared with other pesticides.
