Flowers emit volatiles to attract pollinators, but these volatiles can also attract pest insects. Our study builds on earlier findings that showed that cucumber beetle attraction to squash flowers is mediated by volatile release and cucurbitacin accumulation (Theis, 2014, DOI: 10.3732/ajb.1400171). Of the three main domesticated squash species, only a few varieties of Cucurbita maxima had large quantities of floral volatiles and cucurbitacin (Andersen and Metcalf, 1987, doi: 10.1007/BF01020152); however, these studies were limited in the number of varieties that were examined. Here, we increased the number of C. maxima varieties examined, to identify patterns in floral volatile production, with …
