Highlights
Background & ObjectivesThe Sterile Insect Technique (SIT) is non – intrusive to the environment which entails the release of sterile male flies obtained by mass rearing and this depends on the availability of a suitable blood diet for the flies
A significantly higher mean fecundity was recorded among flies fed five times a week compared with flies fed three times a week
The overall commutative Pupae Per Initial Female (PPIF) and standard deviation of flies subjected to different feeding regime of five and three times per week were found to be 3.05±0.47, and 2.21±0.4 respectively both starting from their first lariviposition date which was 16 days later respectively (Figure 1 and table 1). (Figure 1) G. pallidipes cumulative average Pupae Per Initial Female (PPIF) based on both feeding frequency test groups Flies feed five times per week were produced significantly more pupae than those fed three times per week Tukey HSD, P
Summary
Background & ObjectivesThe Sterile Insect Technique (SIT) is non – intrusive to the environment which entails the release of sterile male flies obtained by mass rearing and this depends on the availability of a suitable blood diet for the flies. The influence of tsetse on African agriculture through the transmission of trypanosomosis continues to be a major constraint to the development of national economies and their achievement of selfsufficiency in basic food production. Others are entomological and intend to disrupt the transmission cycle by reducing the number of tsetse flies These include Sequential Aerosol Technique (SAT) and the Sterile Insect Technique (SIT). The establishment and expansion of G. pallidipes colonies for mass production of sterile male flies proved to be difficult and they collapsed several times due to the deleterious effect of lack of quality blood and good feeding management, high infection rates with the salivary gland hypertrophy virus, unsuitable environmental factors even if it requires the mass production of males for sustainable sequential release until major population reductions are achieved [9,10,11,12,13]
