Table 4. Differences in mating rate between the intra- and inter-strain crosses of the SEW and SEM strains of S. exigua.

Mating conduction	Mating rate (%)*	Mating times per female‡
♀SEW×♂SEM	93.80 a	2.40 ± 1.30 a
♀SEM×♂SEW	87.50 a	2.43 ± 1.22 a
♀SEM×♂SEM	84.81 a	1.97 ± 1.01 ab
♀SEW×♂SEW	74.68 a	1.44 ± 0.62 b

^*Data with the same letters are not significant (Fisher’s exact test P < 0.05).

^‡Mating times per female = the total number of mating times per group/the total number of females having spermatophores per group. Data with different letters are significant (Tukey HSD multiple comparison, P < 0.05).
