Fausse fantaisie dans l’hexagonale confusion .....

lundi 25 juillet 2016 - Rédaction SNP


 Cet article du 22 juillet d’un site anglais marchand Global Food Book’s pourrait apparaître anecdotique - l’aspect culinaire du charançon rouge - est en réalité  bien documenté (voir références). Outre les qualités de toute nature de ces larves de CRP qu’il nous faut bien détruire, il réaffirme tout l’intérêt du piégeage SNP préconise à fond mais également une piste nouvelle celle du Moringa oleifera plante indienne ancestrale miracle associée à la moderne technologie des nanoparticules titanioum de dioxde à une concentration de 75 mg / L TiO2NPS.

Qui se soucie en France et Europe de ses recherches. On préfère continuer à faire un sort aux derniers insecticides de notre pharmacopée ( fin programmée du Confidor) et à essayer de comprendre le désordre tarifaire autour de la technologie de l’endothérapie sur palmier qui semble échapper à toute logique économique...... pas très rassurant quand on sait toute la rigueur que devraient avoir les plans de lutte intégrée (IPM). Antimicrobial Activities

Mazza et al., (2011) investigated the antimicrobial activity of the cuticular surface of the adults, larvae and eggs. They tested this activity against the Gram-positive bacteria Bacillus subtilis (Ehrenberg) Cohn and Bacillus thuringiensis Berliner, the Gram-negative bacterium Escherichia coli Escherich, and the entomopathogenic fungi Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metchnikoff) Sorokin. They also conducted a similar analysis with the hemolymph of R. ferrugineus larvae infected by Pseudomonas aeruginosa (Schroter) Migula, Staphylococcus aureus Rosenbach and E. coli. The study revealed that there are polar substances present on the body of both adults and larvae of the red palm weevil. Thus they offer a protective barrier against microorganisms due to their antimicrobial properties. Pharmaceutical Purposes
According to Elemo et al., (2011), the essential fatty acid and linoleic acid (3.51% of total lipid) found in red palm weevil larva oil make it very suitable for pharmaceutical use.
Serve as Animal Feeds
Being rich in essential nutrients, the red palm weevil grubs can serve as animal feeds. They can also be used as bait for catching fish. Aid Easy Digestion
Due to the high dietary fibre found in the red palm grubs, they can serve as a great source of dietary roughage. As a result, they aid easy digestion of food and helps to prevent constipation and flatulence. Economic Benefits
Sago worms offer economic opportunities to some people especially in the underdeveloped and developing parts of the world. The worms are sold for income generation.
How to Control Red Palm Weevil (rhynchophorus ferrugineus) The major control method of this pest is by applying insecticide through a funnel above the infested part of the tree trunk. The weevils can also be trapped using pitfall traps or pheromone luring bucket. Al-Barty and Hamza (2015), suggested an alternative method for controlling this pest. They investigated the larvicidal activity of titanium dioxide nanoparticles (TiO2NPS) synthesised from the aqueous extract of Moringa oleifera against the Rhynchophorus ferrugineus. The motive behind their study was to ascertain the effects of Moringa oleifera on the glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) activities in tissue homogenates of Rhynchophorus ferrugineus larvae. Their findings showed that there is high mortality in the larval stage when this natural extract solution with titanioum dioxde nanoparticles at concentration 75 mg/L was applied. They concluded that TiO2NPS is suitable to be used alongside with Moringa oleifera extract against red palm weevil larvae.
