[CANUFNET] Scarabées japonais

[Robert Langlois via CANUFNET]

Hi Owen

Thanks for the info. We trapped a few hundreds of them in 2015 and a few thousands in 2016.  We already have done nematodes treatments at the end of july in the nursery last year . We will see if it works and if we will have less beetles next july  ...  A citizen near a parc have so much beetles since 2 years , (in a big public tilia cordata  ) then we will make an application of nematodes at the end of july to see if there will be less beetles en 2018 . Meanwhile, we probably will shoot his tree with safers soap and /or trounce when the beetles will be at their peak . We did it last year with more and less success .  It worked , but a few days later there was as much as before.

Please excuse my clerical errors , I berely never write in english. ( much easier to speak then talk )

Robert:

One would imagine that the application of nematodes in July, as done for control of Rihizotrogus majalis (European Chafer Beetle) would also work for Japanese Beetle, given their similarities.

Subject: [CANUFNET] Scarabées japonais

Bonjour

Le scarabée japonais a commencé à apparaitre et faire des dommages tangibles il y a trois ans dans notre ville , mais l' an dernier était pire que les autres . Plusieurs tilleuls , en particulier , mais aussi des chênes et autres plantes ornementales ont été défoliés . J' aimerais savoir si certaines villes ont développé au cours de dernières années ,une stratégie d' intervention concernant le scarabée japonais  ?

Merci

Hi .

Does anybody have problems with japanese beetles , and what was done to control or get rid of them . Does anybody developed a strategic approach toward this pest ?

Thanks
