Nonmetric multidimensional scaling (NMDS) analysis of Z. cucurbitae antenna-active compounds to headspace volatiles from C. sativus, C. pepo and C. mixta at different developmental stages (flower, immature fruits, and mature fruits). Responses to flower and immature fruit stages are more similar to each other (closer in ordination space) compared to those from the mature fruit stage; the stress value for the analysis was 0.079.
