Table 1. Infection status of wild-caught M. desjardinsi females and the sex ratio of their offspring.

Infection status	Number of broods
	All-female	Female-biaseda	Normalb	Total
S+R+	15	2	2	19
S+R−	6	−	−	6
S−R+	−	1	5	6
S−R−	−	−	3	3

S⁺R⁺: doubly infected with Spiroplasma and Rickettsia.

S⁺R⁻: singly infected with Spiroplasma.

S⁻R⁺: singly infected with Rickettsia.

S⁻R⁻: non-infected.

^a Contain males but sex ratio significantly deviated from 1:1 (P < 0.05 by chi-squared test).

^b Sex ratio not significantly deviated from 1:1 (P > 0.05 by chi-squared test).
