Table 4.

Male mating competitiveness of HC males obtained from different larval rearing units

Male: Male	Fertility (%) (No. of eggs estimated)	Male mating competitiveness index (C)a
Fertile control	90.8 ± 0.7% (3074) (Hn)
Sterile control Wol-unit HC	0 (4550) (Hs)
Wol-unit HC: GUA	44.5 ± 2.1% (9905) (Ho)	1.05 ± 0.10 a
Sterile control IAEA-unit HC	0 (4164) (Hs)
IAEA-unit HC: GUA	46.0 ± 2.8% (10,907) (Ho)	0.99 ± 0.12 a

^aC: Male mating competitiveness index, calculated as: C = [(Hn – Ho)/(Ho – Hs)] × (N/S), where N and S were the numbers of fertile and sterile males

Note: Within each column, values followed by same lowercase letters were not statistically different using Mann-Whitney U-test analysis (P > 0.05). All the data in the table were presented as Mean or (Mean ± SE)

Abbreviations: Hn mean egg hatch rate of fertile control cages, Hs mean egg hatch rate of sterile control cages, Ho mean egg hatch rate of competitive mating cages
