[IBC] Pine Pests on tips of new growth
 

Help! Today I discovered a cluster of ants on an Eastern White Pine,
and looking closer, noticed several green caterpillars with brown heads
covering the tip of branches nestled among the new growth. They were
about one-half inch in length. I pulled off all that I saw. Should I
be spraying or has the damage been done? The tree appears healthy
otherwise.

Any suggestions appreciated.

With thanks,

Probably the pine sawfly (but could be a webworm). The sawfly is
an exotic pest. There are biological controls, and any pyrethrin
or BT pesticide will control both. They eat the needles, and if
you have removed all the critters that's all you need to do.
Keep an eye out for any critters that come in (you may have a
pine in the neighborhood that's infested) and pick them off.

Your bonsai will recover, so don't worry.

Carol: Army worms. The best cure is to put on a pair of latex gloves, fill
a jar with a few inches of rubbing alcohol, and drop them in, one by one.
Put a cover on the jar
and, in an hour or less, voila!
Best regards,
Marty

Or, save the alcohol.

Drip them on the ground and SMUSH them. ;-)

It all depends upon how masochistic you feel at the time.

I found eggs 2 years ago small black dots by houndreds layd in the groove
behind the needles of a black pine and this is a problem ..
I used some winter oil mixed with a product against larvae and eggs

It was the first time iit happened but it seems that a conony of these pests when
a dult can eat out a whole tree( bonsai) within hours like locusts..
so better prevent in case..

Thanks to all for your quick responses on the problem of caterpillars on the
tips of new growth on a pine. The consensus was to remove the caterpillars,
regardless of whether caused by armyworms, sawflies, webworms... which I have
done using the "SMUSH" method suggested by Jim Lewis. (The caterpillars are
small so that simply picking them off the needles probably killed them).
Anyway, I have inspected the pine tips each day since the initial infestation
which yielded about 30 pests, and found only three additional very small
caterpillars each time. Some pine needles have already been damaged and if I
can't keep the caterpillars under control, I will use the BT dust. Thanks
again.
