Chestnut leaf miner moth blizzard

They will only go for Aesculus, I don't think it will kill them on its own. The latest research suggests that the leaves have long enough that the trees can photosynthesise before they are eaten, and are no more susceptible to bleeding canker as a result. Presumably that means they are no more prone to other ailments/attacks as well, which I find hard to believe. Surely if a tree is striped of leaves mid to late summer year after year it will have some effect on the trees ability to store energy?

 

That is the same question that Dalgea O'Callohan proposed at the AA P&D roadshow earlier this year. Well almost. Do you mean to produce energy?

 

If the leaf area is reduced and/or early leaf abscission occurs, I'd agree that the energy production for that year has to be reduced.

 

Have you a link to the research?
