Level of vitellogenin (at transcript and protein levels) in response to fenoxycarb administration. The profile of the vitellogenins [mean ± SD] of the P. tepidariorum females that were treated with acetone and 1, 10 and 100 ng of fenoxycarb per individual. Vg results in the midgut glands at transcript (a.1) and protein levels (a.2), the ovaries at transcript (b.1) and protein levels (b.2) and the hemolymph at the protein level (c). The dashed line box shows the physiological time of vitellogenesis. Lowercase letters indicate significant differences between experimental groups at the same time point (Tukey’s multiple comparisons test, p ≤ 0.05)
