Which stink bug is it?
By Tracey Baute OMAFRA
August 10, 2015 - There are predatory stink bugs and then there are plant feeding stink bugs. It is important to make sure you can ID the good ones from the bad ones. Most are brown with the exception of the green stink bug.
Green stink bugs are the easiest to ID. The adults are quite large and green. The nymphs are very colourful with black, orange and green-yellow markings and are easy to distinguish from others. There are a few brown coloured stink bugs which are a little more difficult to sort out.
There are a few brown coloured stink bugs which are a little more difficult to sort out. Tracey Baute from OMAFRA has put together a Brown Look-A-Like Stink Bug Guide to help with identifying the adults and eggs. Nymphs look similar to the adults but lack wings.
Rarely do we need to spray for stink bugs, though control may be warranted in IP food grade and seed soybeans if an average of one brown stink bug or green stink bug per 30 cm (1 ft) of row or 0.2 bugs per sweep is found during the R5 to early R6 stages.
