Does anyone know of any natural predators to the jb? I've got jb's in my garden and have been researching organic ways to control them for a month now to little avail...

[edit] Beetle bag

Do you think it appropriate to add a picture of a standard japanese beetle trap and information on the pheromone bait?

Courtland 20:54, July 12, 2005 (UTC)

Yes, I was wondering where the bag picture was myself. --Descendall 04:46, 14 November 2006 (UTC)

[edit] Beetle bags

There's a lot on controversy about those bags, actually... most entomologists now say they end up attracting beetles from a large area, and they tend to feed on what's nearby before going for the pheromone bait.

Actually, the USDA Animal and Plant Health Inspection Service 'Managing the Japanese Beetle' reference doesn't say that the beetle bags don't work, but that they shouldn't be too close to the plants to be protected. The instructions on the bag I bought said the same thing...keep it 10 ft away, on the upwind side. And the USDA ref says 'Traps are most effective when many of them are spread over an entire community', which is certainly true. It is _very_ satisfying to have the traps 'eat' the beetles instead of the beetles eating my newly planted linden tree. Should cut down on lawn damage later too. PBarak 23:33, 17 July 2006 (UTC)

[edit] horrible english?

does this line make sense to anyone:

"These are spiney, and thus intended to ward off predators, but create an impression."

I can understand what they mean but surley it should read something like - "Their spines are intended to ward off predators." I am not sure about the create a impression part - perhaps it could mention that they are impressive looking or somehthing? - That is still subjective.

The map of the range of the infestation is outdated. I lived in NW Arkansas last summer and they were everywhere. [128.187.0.164, 14:19, 31 Aug 2006 --added manually by wikipedian below. Please sign entries with 4 tildes.]

The USDA map is undated, but I did locate a 2005 distribution map showing an infestation in NW Arkansas. See: http://ceris.purdue.edu/napis/pests/jb/imap/jb2005.html . The source of data for the map is NAPIS, which is public domain, but the map itself is probably not. I have contacted the Center for Environmental and Regulatory Information Systems for permission to use image in wikipedia. PBarak 12:48, 1 September 2006 (UTC)
