I noticed some of my cucumbers were yellowing. I was unsure what was causing this and then upon further inspection I noticed tiny holes in the cucumbers.
After doing research I learned these holes were caused by pickleworms, making them inedible. 🙁 Below is a picture of the pickleworm once I broke the cucumber apart. Glad I didn’t eat that.
There are several natural enemies of the pickleworm including various beetles and imported fire ants. At this point I figure I must not have these becuase so many of my cucumbers are infested. At first, I thought my only choice was to use a chemical insecticide. But then I read in my “Rodale’s Chemical-Free Yard and Garden” book that BTK, Bacillus thuringiensis var. kurstaki, should kill the pickleworm. If you nee more info, The University of Florida has a great page on pickleworms.
