  1. Only experiments where at least 10 mosquitoes were dissected for salivary gland infections were used for correlating sporozoite infection rate with parasitaemia and gametocytaemia. Based on this criterion, experiments 1, 13, 14, 15, 17, 29 and 30 were not included for analysis
  2. ND not done, NA not applicable
