We have had a large infestation of Mexican Bean Beetle on this year’s ‘Rattlesnake’ green bean crop. We decided to try to parasitic wasp that preys on the beetle’s larvae. So far, they seem to be doing their job well. We’ve seen plenty of brown parasitized beetle larvae since the release. We ordered them from Biocontrol Network- http://www.biconet.com/
And that’s preying- not praying!
