Re: submission
One thing about Japanese and Asiatic beetle populations is that they are
somewhat related to the soil moisture of the previous year when the eggs are
laid. If the soil is dry there is a very low survival rate. I've just
noticed a few JB's up in the Catskills but not in great numbers. The
populations also seem to be regional as far as outbreaks go. I suspect that in
wet years like this there are also pathogens that affect the grubs during the
spring but not sure about that.

Betty Mackey's observation that there are few Japanese beetles this
year was most interesting, because I'd noted the same thing
recently. Practically no JBs or rose chafers this year in NW
Connecticut. I contacted CT Coop Ext. about this but haven't gotten
an answer yet. If anyone comes across any Coop Ext. bulletins or
other factual information about the effect of meteorological
phenomena on insect populations this year, or any other proposed
reasons for the dearth of beetles/moths this year, please post a link
to it. Thanks for the confirmation of my own observations--I'd
started to wonder if it was just me!
