Crossing tests among two populations in the absence or presence of antibiotic treatment in B. longissima. Lp. B. longissima collected in Lospalos, East Timor (Pacific clade); Di, B. longissima collected in Dili, East Timor (Asian clade); −, antibiotic-treated insects; +, antibiotic-untreated insects. Error bars indicate SEM. Means with the same letters do not differ significantly (Tukey–Kramer test, P > 0.05). Gray parts indicate percentage of females in each cross. In pairs, n = 9 for Di⁺ Lp⁺ (female × male, the same in the following), Di⁻ Lp⁺, and n = 8 for Lp⁺ Lp⁻, Di⁺ Lp⁻, and n = 6 for Di⁺ Di⁻, Lp⁻ Lp⁺, Lp⁻ Di⁺, n = 5 for Lp⁻ Di⁻, and n = 7 for the rest of the crosses. In the number of eggs, n = 165, 93, 75, 181, 131, 84, 57, 151, 131, 97, 76, 175, 132, 64, 89, and 161 for Di⁺ Di⁺, Lp⁺ Lp⁺, Lp⁺ Di⁺, Di⁺ Lp⁺, Di⁻ Di⁻, Lp⁻ Lp⁻, Lp⁻ Di⁻, Di⁻ Lp⁻, Di⁺ Di⁻, Lp⁺ Lp⁻, Lp⁺ Di⁻, Di⁺ Lp⁻, Di⁻ Di⁺, Lp⁻ Lp⁺, Lp⁻ Di⁺, and Di⁻ Lp⁺, respectively.
