Shifting Preference between Oviposition vs. Host-Feeding under Changing Host Densities in Two Aphelinid Parasitoids
Figure 1
Mean number of whitefly nymphs killed by parasitism or host-feeding by parasitoid in single-instar experiment.
A, B: killed by 1 d-old Eretmocerus hayati or Encarsia sophia in 24 h, respectively. An area of 3.5 cm2 of a leaf on a potted tomato plant was covered by a clip cage. Data points with different lowercase letters in each line indicate significant differences (HSD test; P<0.05) in number of hosts parasitized (continuous line) or fed (broken line). Vertical bars indicate ± one SE.
