Ambrosia beetles

[ktrain]

Here is another item that is supposed to help with ambrosia beetles/ borers.
It doesn't seem 100%, and I believe you have to reapply after rains.
If they do happen to get your tree...I used this in full concentration with a syringe to shoot into the holes.
It did seem to work.

@"ktrain"#2 took a look at this insecticide for borers and Ambrosia beetles. As you suggested it's a great solution for a nasty problem in your home Orchard. 7.9% Bifenthrin. Is a pretty strong pyrethroid that I have seen used in some 90 day Orchard pesticide Solutions that are rated 90 days. I guess if it rains you have to reapply another great suggestion Kevin well this one is not organic it is fundamentally a pyrethroid and should be safe to use on fruit trees. I definitely would use this product.

If found early you can treat. If not burn.

Nice beer selection from the oldest brewery in the US.

Nope. It was a new almost seedless blood orange. 30 years in the making.
Good beer. That is helping with burning the old tree.

Ouch - tough loss.

It is all part of it. But yeah bad day. Still burning.

We took heavy losses from ambrosia beetles here a few years ago. I found in the end that they're attracted to wounds and dying wood. I created the problem myself because I top-notch a lot to induce branching on lazy buds. I'd been attracting them and giving them an easy entry point. Since figuring it out I now seal all my open wounds in the first half of the season while they're active. Since I started doing this I haven't seen any trace of them.

The nasty thing about these borers is that by the time you know you have a problem, it's way too late. Best you can do is cut down to the lowest entry point... which is most often near to the ground.

 

[ktrain]

Yep...I'm going to start preparing for them real soon.
Since the in ground trees appear to have survived the winter...not is the time.

 

[GoodFriendMike]

The two citrus had some winter die back.
Seems that is what attracted the beetles.

is there a spray to try an prevent them from attacking?

I think something like Spinosad is on the safe side and effective. I haven't used it for Ambrosia specifically but it's listed as one of the bugs it works on

Puts a whole new meaning to Hank Williams song “There’s a tear in my beer”.
