    Hi, I am doing a project at college on breeding fruit flies.
    As far as any research I have been able to find, fruit flies usually breed within 6 days.
    So far other people's projects have sprouted some maggots and larva but it has been 2 weeks and 4 of my 9 original flies are dead with no offspring.
    I thought it may have something to do with the food I've been feeding them, they have been given the same growth mediem other projects were given, however I have added some bananna to mine which could possibily have some kind of pesticide that affects them breeding.

    As far as I can tell, I have at least 2 females and the rest are males, so no problem there and they came from the same batch as everyone elses flies.
    Are there any other reasons they may not breed?
    Temperature, light or dark etc.

    Help would be greatly apprecieted.

    I think your fly mortality rate is unusual these seem to be hardy creatures, and whenever I want to bring some fruit in my dorm to ripen (usually bananas and nectarines) some will be buzzing around. Have a look at this web site which I found by entering "fruit flies and raising" into Google.

    Good luck
