Fig 2 - The effects of egg separation on hatching patterns of Locusta migratoria eggs. The frequency distribution of hatching times for eggs kept in the pods (A) or in masses of 20 eggs (C) and those kept as separated eggs (B, D) when the mean hatching time was assumed to be 0 h. The relative times of hatching for the eggs kept in the pods (E) or in masses of 20 eggs (F) and those kept as separated eggs when the mean value for the former eggs was designated as 0 h. The number of hatched eggs followed by the number of tested pods in parentheses is given in each panel. Asterisks indicate a significant difference between the two treatments (p < 0.05; t-test).

Fig 7 - The effect of the time of separation of Locusta migratoria eggs on the hatching time. The differences in mean hatching times between eggs separated and those kept in contact with each other (controls) are plotted against the time of egg separation gauged based on the mean hatching time for the control eggs (A).

Open and closed circles indicate eggs separated and those kept in masses, respectively. Each datum point is based on 16–20 eggs.

Fig 14 - The effects of pairing of Locusta migratoria eggs at different ages on hatching time. A. The mean hatching intervals between the first and second hatching eggs of the mixed pairs are plotted against the differences in mean hatching time between the younger and older controls in which two eggs were kept singly. B. The differences in hatching time between the first hatching eggs of the mixed pairs and older control eggs (from early-produced pods) are plotted against the difference in hatching time between the two control eggs. C. The differences in hatching time between the second hatching eggs of the mixed pairs and younger control eggs (from late-produced pods) are plotted against the difference in hatching time between the two controls. The diagrams on the top show combinations of eggs from older eggs (gray) and younger eggs (white). A total of 38 pairs of pods were used. Closed circles in (B) and (C) indicate the means significantly different from the controls (p < 0.05; Tukey's multiple test).
