  Abstract  
  In the context of an integrated control strategy for house fly, Musca domestica, development within an urban solid waste treatment plant, tests were conducted to evaluate the sterilisation of M. domestica adultsby feeding them with Insect growth regulator (IGR) products commonly used for larvae control. Products containing triflumuron, buprofezin, hexaflumuron, and diflubenzuron were evaluated in the laboratory using insects collected in a waste treatment plant. Each test was conducted on pairs of house fly adults aged 1, 2, 3, 4, and 7 days. Environmental conditions were recorded during the tests; the temperature was 24C + 1C and the RH was 65% + 10%. Each treatment was replicated three times and consisted of exposing ten pairs of house flies to contact with discs of filter paper treated with 0.1% or 0.75% of each active ingredient diluted in a water solution containing 40% sugar as an attractant. The pairs of house flies were exposed to the treated discs for 3 to 6 days in a cage of 4.67 l. The results show that some IGRs (diflubenzuron, hexaflumuron, and triflumuron) sterilise 100% of eggs laid by couples ofMusca domestica adults aged 1 day. The sterilisation effect is similar in adults that come into contact with these IGRs for up to one week after their emergence.
