Yes, insects are also vastly reduced. In my region, there’s an increase in ticks (and tick-borne disease) because there are less insects, leading to less birds, leading to thriving ticks. So, an annoying side effect of reduced insect count is that we have lots of ticks in our gardens.
BTW we have non-organic agricultural fields in 50m distance of our house, so that _might_ be a factor for the dying insects.
Oh, and organic agriculture also uses pesticides. They just use different („natural“) ones.
You'd think there'd also be an uptick (ha!) in animals that eat ticks, but maybe that takes a lot longer to correct itself. If it wasn't for the prevalence of pesticides, insect populations would restore due to a shift in balance - that is, less insects = less predators eating them, less predators = more insects, etc.
