Diploid Male Production of Two Amazonian Melipona Bees (Hymenoptera: Apidae)

Table 2

Variation of the sex ratio in colonies of Melipona seminigra merrillae. Queens that produced diploid males (a 1 : 1 sex ratio in the first brood comb) did not maintain this ratio in the second and third brood combs.

Colony	♂	♀	Sex ratio	G-test
20/D1	53	54	0.49	NS
20/D2	28	15	0.65	S
20/D3	19	99	0.16	S
27/D1	39	54	0.42	NS
27/D2	44	36	0.55	NS
27/D3	17	41	0.29	S
29/D1	26	32	0.45	NS
29/D2	33	65	0.34	S
29/D3	03	75	0.04	S

*Null hypothesis, in a 1 : 1 sex ratio; G-test, critical values (G = 3.841; DF = 1; 𝑃=0.95 and α = 0.05); S: significant; NS: nonsignificant; D1, first brood comb; D2, second brood comb; D3, third brood comb.
