The only known specimen to be found in Ontario so far has been in a home near Hamilton this spring. We are trapping and surveying but don't expect it to be at pest levels for a few more years yet. As for soybean aphids, yes they are increasing here too. Eastern Ontario in particular saw numbers climb to above threshold very quickly last week, though I suspect more fields in Central and Southern Ontario will also have this happen. I was just about to write a blog about it actually so good timing on the question. Hi Kevin

Still lovin' your Bug Blog. Any news on brown marmorated stink bugs? Also... Isolated fields in Iowa have had soybean aphid numbers jump to well over threshold. Most are holding at low levels. What are you seeing? Hi, Tracey! Still lovin’ your Bug Blog.

They protect them from their natural enemies (throw any predators walking on the leaves off the plant etc). In return the ants suck the sweet honeydew that the aphids are secreting from their "tailpipes". So no, ants are not a natural enemy but they do help you spot aphid infested plants in a field.

We have one variety in our plot (only one untreated) that is littered with Aphids. Seems as though ants are taking them and carrying them somewhere... The plants with Aphids have anywhere from 10-40 ants on them. Hello Tracey,

Correct insecticide timing is when the larvae have just hatched and are present on the whorl, tassel or leaves before they make it into the ear. Insecticides can't penetrate the ear and these larvae don't really feed on the outside of the ear again once they are safely inside feeding on the kernels. Hi Dan
