The influence of topical juvenile hormone (JH-III) treatment on ovarian development in queenright workers.

		JH-III	DMF	Control	Kruskal Wallis test
Trial 1	Length of marginal cell (mm)	2.72 ± 0.15 (5)	2.68 ± 0.16 (6)	2.68 ± 0.11(4)	0.83
	Length of terminal oocyte (mm)	1.90 ± 0.41(5)	1.27 ± 0.23 (5)	0.93 ± 0.09 (4)	0.14
Trial 2	Length of marginal cell (mm)	2.74 ± 0.06 (8)	2.74 ± 0.06 (8)	2.89 ± 0.08 (7)	0.1

One-day-old workers were topically treated with 70 μg juvenile hormone (JH-III) dissolved in 5 μl DMF, 5 μl DMF vehicle (DMF), or were similarly handled but not treated (Control). We measured the length of the marginal cells and of terminal oocytes of these bees on day 7. The table shows mean values ± standard error of the mean, sample size in parentheses (n). The P-values of the Kruskal Wallis tests are shown. DMF = Dimethylformamide.
