Figure 7. Inhibition of egg-laying by noxious mechanical stimuli.
Number of eggs-laid in the first half hour following transfer with a wire pick divided by average number of eggs laid by the same strain per half an hour, in N2, −T, −P, −TP, and −TPF, n=29-33 each. Significant differences relative to N2 are indicated by a double asterisk (P<0.01). −TPF is also different from −T, (p<0.01).
