Objective Background:Filth flies such as housefly (Musca domestica Linnaeus),the Australian sheep blowfly (Lucilia cuprina Wiedmann),the common green bottle fly (Lucilia sericata Meigen),and the oriental latrine fly (Chrysomya megacephala Fabricius) commonly found in China have plagued man since prehistory times.Insecticidal application for fly control in this region has led to some problems.There are abundant literatures which revealed that calcium cyanamide (calcium cyanamide) had bioactive efficacy to many organisms.In this study,we used calcium cyanamide to test its efficacy to housefly.Methods Maggots together with their larval rearing medium were prepared to place into a 100ml beaker and mixed gently and evenly using glass rod.10g complex was fetched from 100ml beaker and introduced into a 25ml beaker.Rongbao? dust were added to the mixed larval rearing medium and gently mixed again.The 25ml beaker was covered by a gauze fastened tightly using a rubber band.Dead maggots in the complex were singled out,counted and recorded every day until 72 hours of deadline that we previously defined.Results Our laboratory bioassays showed that calcium cyanamide (at dosage of approximately 2% (W/W)) resulted in average mortality rate of 37.67% on day 1 and 100% on day 2,compared with average mortality rate of 34.51% on day 1,89.80% on day 2 and 100% on day 3 at dosage of approximately 1% (W/W).Conclusion This outcome demonstrates that the application of calcium cyanamide can be used as part of filth flies integrated management.
