1. Here is 10 sweeps' worth of lygus bugs captured this week around Fairview, Alberta. Do you think the count is over threshold?

2. A CCC agronomy specialist found these two green diamondback moth larvae in a sweep net. Are diamondback thresholds based on sweep net counts?

3. Sweep netting can show the biodiversity of insects in the flowering canopy of a canola field. The bottom arrow points to a lygus nymph with developing wings. You include these in your threshold counts along with adults. The top arrow points to a beneficial insect looking like its about to eat a diamondback moth larva (middle arrow). What is that beneficial insect?

4. Grasshoppers might show up in your sweep net, but grasshopper thresholds are not sweep-net based. They are based on counts per square metre. The nominal threshold for grasshoppers in canola is ______ per square metre. (Fill in the blank.)
