Several authors (Zvereva & Zhemchuzhina, 1985;
Hogsette & Washington, 1995; Ward et al., 1999) report
that female flies can be very choosy about where they
oviposit with marked preferences for particular substrates.
The oviposition sites selected are frequently those that are
most favourable for larval development (Ward et al.,
1999). Availability of suitable oviposition sites can in
turn affect the fecundity of the flies. Female house flies
presented with oviposition substrates that lack important
taste or olfactory stimuli lay very few eggs (Zvereva &
Zhemchuzhina, 1988). House flies and other insects need
a balanced diet consisting of both sugar and protein in
order to successfully mature their reproductive system
