Table 5 Mating competitiveness values for An. arabiensis GAMA males irradiated at 75Gy competing with fertile An. arabiensis AMAL males for AMAL females under natural conditions in semi-field 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 ± 7.9    
Sterile control   1.3 ± 0.6    
1:1:1 1 66 ± 17.3 47.3 25.8 0.36
5:1:1 5 36.7 ± 5 16.8 58.4 0.29
10:1:1 10 23.7 ± 14.6 9.8 73 0.29
Average CI = 0.31
  1. S/N refers to the ratio of sterile to fertile males in each treatment cage
