Bug obliterating my squash
July 20, 2009
I recently noticed some of my squash browning on the leaves and yellowing on the stems. Upon further investigation I found these bugs I have never seen before and they are ravishing my zucchini. Can you please help identify them so I can remove them?

These are nymphs of a Squash Bug in the genus Anasa, which can be verified by this photo on BugGuide. The most likely member of the genus is Anasa tristis, and BugGuide has this to say about this injurious species: “This is the most injurious species of coreid in Florida (3) Injects a toxic saliva into plants, causing wilting and blackening of leaves. Can also act as vector of cucurbit yellow vine disease, which kills plants.”
