Catch-and-Release Trap * le Piège stérilisateur

French Abstract

Encore une nouvelle idée développée par le chercheur et Egypto- italien Nabawy Metwaly de Green World S.r.l., Roma 00040, Italy (1). Ici il s’agit de pieger les charançons et de stériliser les mâles,  de les infecter ( essentiellement avec  bactérie Bacillus thuringiensis l’insecticide le  plus utilisé au monde en agriculture biologique ), puis de leur permettre de repartir pour rejoindre des couronnes de palmes pour ré-infecter  d’autres CRP avant de mourir. … Tout de même !

L’inventeur à  l’air content de lui ,  il faut maintenant poursuivre le recueil d’informations.

An Advanced Catch-and-Release Trap for Controlling the Red Palm Weevil

 The aim of the research was to develop a catch-and-release trap for monitoring and controlling RPW (Rhynchophorus ferrugineus, red palm weevil). The RPW insects were attracted through the use of an aggregation pheromone located into a dispenser inside the trap. The RPW adults entered through an entrance door into a sterilization room where they were sprayed with a solution containing the chemical sterilizer product “lufenuron”. The adults were then forced to move into a contamination room where it was present a wet media containing spores and hyphae of Metarhizium anisopliae and spores and crystalline insecticidal proteins of Bacillus thuringensis. The sterilized and infected RPW adults were counted and released into the environment where they reached new palms and join natural populations of RPW. Preliminary experiments showed that the catch-and-release trap was able to reduce the fertility of RPW adults and to increase their mortality after contamination with entomopathogens. Moreover, the infected RPW adults were able to infect untreated RPW larvae leading to a larvae mortality of 93% within 30 days. In conclusion, the advanced catch-and-release trap represents a safe and effective tool to monitor and control the population of RPW pest without environmental pollution and risks for human health.
