Table 4 Mating competitiveness values for An. arabiensis GAMA males irradiated at 70 Gy competing with fertile An. arabiensis AMAL males for AMAL females under laboratory conditions in 30 cm × 30 cm × 30 cm bug-dorm cages

From: Mating competitiveness of sterile genetic sexing strain males (GAMA) under laboratory and semi-field conditions: Steps towards the use of the Sterile Insect Technique to control the major malaria vector Anopheles arabiensis in South Africa

Treatment S/N Observed Hatch Rate ± SD (%) Expected Hatch Rate (%) Induced Sterility (%) Competitiveness value
Fertile Control   89 ± 16.2    
Sterile Control   3 ± 2.5    
1:1:1 1 77 ± 17.9 46 13.5 0.16
5:1:1 5 63 ± 21.6 17 29.2 0.08
10:1:1 10 44 ± 24.1 11 50.6 0.11
Average CI = 0.12
  1. S/N refers to the ratio of sterile to fertile males in each treatment cage
