Biochemical Effects of Some Chitin Synthesis Inhibitors Against Red Palm Weevil, Rhynchophorus ferrugineus Insect

Abstract

The journal of Toxicology and pest control is one of the series issued twice by the Egyptian Academic Journal of Biological Sciences, and is devoted to publication of original papers related to the interaction between insects and their environment. The goal of the journal is to advance the scientific understanding of mechanisms of toxicity. Emphasis will be placed on toxic effects observed at relevant exposures, which have direct impact on safety evaluation and risk assessment. The journal therefore welcomes papers on biology ranging from molecular and cell biology, biochemistry and physiology to ecology and environment, also systematics, microbiology, toxicology, hydrobiology, radiobiology and biotechnology. www.eajbs.eg.net

A Review on Digestive System of Rhynchophorus ferrugineus as Potential Target to Develop Control Strategies

“…As mentioned before, one of the transcripts found and suggested to be targeted is the chitin synthase (CHS2) gene, as it is involved in developing chitin in the gut lining of RPW. Chitin also builds up the well-developed mouthparts of adult and larvae RPW, which are strongly chitinized, enabling the pest to destroy the rough components of the palm vascular system [ 14 ]. It has been proven that chitin synthesis inhibitors such as chlorfluazuron, hexaflumuron and lufenuron showed efficiency against RPW larvae.…”

“…The current strategies reported for the prevention and control of RPW are based on a natural enemy as a biocontrol agent, food-baited pheromone traps and insecticides [ 6 ]. Out of the various choices, broad-spectrum insecticides are currently the main strategy for RPW control [ 13 , 14 , 15 , 16 ]. However, the usage of commercial broad-spectrum insecticides, such as phosphine [ 17 ] and ethion [ 18 ], has been proven ineffective, as RPW develops a resistance towards them [ 16 ].…”

However, the usage of commercial broad RPW has been reported to be most destructive in its larval stage [11].…”
