Japanese Beetles Prefer Barbera Vines

by Brian Gilp » Wed Jun 27, 2007 12:19 pm

Found this odd and maybe there are other reasons related to the size of the vines or their locations within the vineyard but there seems to be fairly noticeable preferences among my Japanese beetle invaders. Far and away their favorite vines are the Barbera. This could be because they are second year vines and thus bigger than all the other vines which are first year. However, preferences among other vines are not as easily explained. The preference for the Aglianico may be because it is planted next to the Barbera. However in other cases the beetles will park on one two rows (Petit Verdot) largely skip two rows (Cab Franc) and then munch down on the next two row (Cab Sauv). It is actually quite interesting. Not sure if there is any real study on the issue or not. Just from my observations the preference in my vineyard would follow something like this.

1. Barbera
2. Aglianico
3. Cab Sauv
4. Petit Verdot
5. Sangio (Clone 12)
6. Sangio (Clone 7)

Note actually a big difference here between the clones and the break between those that are seeing significant attack (clone 12) and those that are not (clone 7).

7. Cab Franc
8. Syrah
9. Tannat

Seems the critters have a preference for my Norton vines. I've also notice some nibbles on my Concord and Catawba. They don't seem to like the Vidal, Chambourcin, or Traminette. The JBs here in the east must have a developed a taste for 100% American grapes.

The vineyard is a small and on my property. 225 vines total (25 vines per variety). I am located in Maryland about 40 miles south of DC and half way between the Bay and the Potomac. Hot and humid with 3700 degree days and 40 inches of rain on average. No real viticultural history in these parts hence the wide variety of vines. trying to see what will work.

The Tannat was planted based upon the relative success that Dennis Horton had with it and recommendations of others in VA.

Aglianico is just a shot in the dark. Believe I have the only vines in the state. The heat should not be a problem. Not sure if I keep it from rotting.

All the grapes are for my own home production.

Thanks for the details on what you're doing, Brian. Sounds a bit like a passion run amok to me.

Funny, my Japanese Beetles seem to prefer Chambourcin to Norton/Foch/Seyval/Vignoles. 'Course they're West Virginia Japanese Beetles.

Hmmmm, must be a regional thing, me being in No. Bama.
