Lezersvraag: Ik zoek een middel tegen de rode palmkever

Nee, dat is er niet. Het beestje is een groot probleem en levert enorme schade op.
Zelfs intensieve bestrijding/preventie met alle mogelijke middelen levert weinig resultaat op:

Intensive chemical treatments have been used to protect the Phoenix palms and to try to cure affected trees. Despite the difficulty in operating in the public gardens environment, foliage spraying has been conducted with various insecticides: Fenitrotion, Clorpirifos, Diazinon or Metidation. Preventive treatment of all the palms, even healthy ones, has been repeated once a month outside the tourist season.

Insecticides such as carbaril and imidacloprid have been injected several times and in various places all around the stems of palms. Simultaneously, a programme of mass trapping using aggregation pheromone and semi-synthetic kairomone has been initiated (Esteban-Durán et al. 1998). But despite all these efforts, more than one thousand Phoenix have been killed. In an area that extends from Motril to Nerja, in the Mediterranean coast of Granada and Málaga, the weevil is still present and has spread to villages close to the initial points of infection.

Zeer vervelend insect!
