[IBC] beetle on my juniper
I noticed today that 2 pads of foilage on my Shimpaku juniper were brown.
Two days ago, these pads were perfectly fine, a healthy green, no signs of weakness. As I was looking at what may have been the cause, I saw some sort of bug on the trunk. I do not know what kind of bug it was, but it is about 1 inch long, brown, has 6 legs, a small head and it looks like it had wings. It looks like some kind of beetle? My concern is whether or not the bug is what caused this immediate proble, or if I should be worried that there is something still wrong. THanks for all the help. - Colin Horn, SF Bay Area, CA ************************************************** ****************************** ++++Sponsored, in part, by Boon Manakitivipart++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?

THanks for all the help. - Colin Horn, SF Bay Area, CA T'warn't the "beetle." Beetles are chewing insects; they eat things; they don't turn them brown. Spider mites or other sucking insects (most of them small and hard to see, with ONE unlikely exception, see next) might turn juniper needles brown (but not at this time of year -- ASSUMING your juniper is outside). The exception _might_ be one of the true bugs (stink bugs, etc.) but I don't know any that think junipers are tasty. They'd fit your description -- kinda. If your tree is an "indoor tree" (and their ain't no such animal, really) you could have any or all of the sucking bugs (scale, aphids, mealybugs, etc.), and I'd look closely at your tree's branches with a hand lens. Other causes of browned needles include bad roots from over/under watering. Spraying with something that should not have been sprayed on a juniper (read the label!) and broken branches. It could also just have been that branch's time. It IS winter, though 2 days is a bit sudden, especially since juniper needles usually take weeks to turn brown. How do other branches look? A little history of this tree -- water, fertilizer, where kept, how long you've had it, etc. -- might help. A parting thought: HOW brown? Juniper needles often turn a _bit_ rusty looking in winter, then go back to being green in spring.

I keep the juniper outside on my porch. Ive never had problems with insects before except for scale last year, but nothing serious. The tree gets sun in the daytime, and I keep it watered, but I try to lean towards the dry side since its a juniper. I know that overwatering definitely was not the problem, and I seriously doubt that underwatering would be a problem. I've had it for 1 year, ive been training it the whole time and its been healthy ever since. With the two pathces of foilage that have turned brown, these patches are amongst other patches coming form diferent sources, but none of the other patches have changed- still green and healthy. The damaged patches have turned a light medium brown, but i can see with a couple "needles" on these pathes that the tips on some are gren, while close to their branch is brown. They are still soft to the touch, not dry or crusty. If beetles dont do this kind of damage, what can do it in such a fast span of time? I dont think any changes in environment could do something like this in a matter of 2 days. Im open for any sugestions. Thanks again,- Colin Horn, SF Bay Area, CA Well, my best guess would be aphids, scale, or spider mites. Use that hand lens and examine the tree closely. Spider mites are tiny and (often) reddish. Aphids are bigger and reddish, white/clear or black and soft looking. Scale looks like white or gray lumps on the limbs. A hard spray of water into the branches (repeated every day for a few days) will get rid of either of the first two. At this time of year, a dormant oil spray will get rid of any of these critters. It's really impossible to diagnose from 3000 miles and sight unseen, though. Good luck.

Although not as likely as males to "spray," I have had even neutered females do it as a territorial thing. The effect is as you describe. Now, spider mites, etc., might be as or more likely but in searching for answers we should consider all possibilities. When my plants have been sprayed they have come back.
