I agree with you completely.

I have protected the trees on my property.  Doesn't help the trees in local parks or those planted on the streets.

They are all at risk.

I think it's just as easy to spray BT and DDT over a large area.

I have some doubts, myself about the damage created by DDT.

There are many other much safer ways to control pests.

I use many here without resorting to dangerous chemicals.

There's a new one on the market based on a peptide found in an Australian spider venom.

Most people lack the knowledge or interest in looking for safer methods.

It's always easier to take the most available option.

They seem to have wide likes here in NE NJ.

I've found them on pears, apples, plums,grapes Raspberries and most of the street trees around these parts.

I suspect they will have a large impact on native trees.

Based on my casual observations it eats just about everything.

Has some favorites like Ailanthus altissima and Evodias.

Found on grapes, maples, apples, raspberries.

Looks like the eggs fall to the ground in spring and the nymphs climb trees to feed on softer plants structures like tender shoots and stems.
Everything in moderation, including moderation
The last instar prior  to becoming the moth is brightly colored red and black.

Couple of better photos with a macro lens. This is the first instar soon  after hatching .  The nymphs rushing up into the catch jar where a pheromone lure is placed.

They are highly reproductive in our environment.

Luckily only one generation per season

They were scaleld down photos.  I'll get one in the morning a bit larger.
We have a new pest in town.  An introduced one form China purportedly  via a load of stones from China.

This one attacks most plants we grow.  Favorite is the weedy Tree of Heaven, Ailanthus altissima

Images attached of the egg cases, first instar pest and newly developed trap that uses a pheromone lure to attract them into a container for disposal. I've seen them on Peonies, Grapes, apples, Pears and  Quince.

Images of a trap recently developed using a pheromone lure based on Methyl salicylate, wintergreen.

A bit of background on insect pests.
Most are blind or have limited vision.
They generally find mates and food via scent using the antennae atop their heads.

The lures work by tricking them into thinking their approaching food or a mate.
It so happens that the chemical lure ( pheromone) for this particular pest is a common substance many folks may have in the bathroom medicine cabinet.
Methyl salicylate, or better known as wintergreen.
 If you do purchase the lure you will smell wintergreen.
 I purchased the pheromone lures from

Traps came from

There's two different ones.  One has a removable jar to empty and replace. 
 The other is a plastic bag that doesn't allow for emptying and replacing.

Your plants look more like a mineral deficiency than a virus.

Have a look at some examples of iron deficiency on the web.
