Living in the Southeast US, one of the tragedies of organic gardening is that growing zucchini is very difficult. This year’s zucchini wars have been very successful – we have gotten some squash! We started squashing adult Anasa tristis, the squash bug, in late May. Finding A. tristis egg masses has been a very common thing in our garden, but it is very rare to find nymphs.
Our garden has had many Coleomegilla maculata adults and larvae – perhaps they are eating the A. tristis eggs?
Kelly found a wasp (Sphecidae?) eating Ceresa festina (same family, Hemiptera, as A. tristis) in the garden – perhaps this wasp has been cleaning up the A. tristis nymphs? Or perhaps the two predators are synergistic? Possibly there may be fungus that is taking out the A. tristis?
All I know for sure is I had zucchini for dinner and the garden is working right this year!
