Figure 8. Emergence of the adult parasitoid Lebia grandis, and host beetles, when reared individually on three species of Leptinotarsa. Difference is highly significant for proportions on Leptinotarsa juncta compared to the two other species (p < 10−6, χ2 test; n = 55, 114, and 107 respectively). Crosshatched portion of “neither” denotes added host mortality attributed to parasitoid effect without parasitoid emergence (see text for explanation).
