CONCLUSIONS 

 Major conclusions formulated as a result of this research are as 

 fol lows : 



1. Rototilling was found to be a satisfactory method for drying 

 wet manure although more time and effort are involved than when a tiller 

 is used in a routine manure management program. 



2. When a tiller is properly incorporated into a routine manure 

 management program, benefits include fewer manure clean-outs per year, 

 the increased value of tilled manure as a fertilizer, and reduced costs 

 for fly control when compared to the use of pesticides. 



3. A tiller is not necessary in order to have dry manure on a 

 poultry farm. Likewise, owning a tiller will not compensate for over- 

 all poor management practices. 



4. Liquid manure cannot be tilled to a drier state unless a 

 stabilizer is added. Wood chips aid in the drying process by creating 

 increased surface area and adding consistency. Builders' sand makes 

 manure heavy and difficult to work with. 



5. Larvae of Ophyra aenesaens are predaceous on house fly larvae 

 and can kill more than 20 first-instar larvae per day. Large popula- 

 tions of Ophyva adults are pes t i ferous and would be an unwanted 

 nuisance on a poultry farm. 



6. Larvae of Hevmetia illucens and Ifo-isoa dormstiea can coexist in 

 larval media in the laboratory and in the field by developing at dif- 

 ferent depths i n the media. Drying manure would eliminate both of these 



flies.
