Musaa domestica adults emerged in approximately the same numbers from 

 all jars and it was concluded that no antagonistic relationship existed 

 (Fletcher et al . , 1956) . 



Kilpatrick and Schoof (1959) noted thai larvae pf M. domestica were 

 absent from privies where excretia was semi liquid and infestations of 

 H. illucens were heavy. Attempts to dry the excretia with sawdust or by 

 water manipulation caused excretia to crust over and resulted in an in- 

 crease of house fly breeding and a decrease i r. soldier fly breeding. 



Relationship with Musaa domestica (L.) in poultry manure . The 

 presence of larvae of M. domestica and H. illucens in poultry manure is 

 also well documented in the literature (Cunningham et al., 1955; Tingle 

 et al., 1975). The latter authors found them in Florida and claimed 

 that the house fly population at one farm was being controlled by the 

 soldier fly population. Few details were given to support that claim. 



The hypothesis that larvae of H. illucens and M. domestica are 

 antagonistic was again tested in the lab for Furman et al. (1959)- This 

 time, larval house fly populations did not develop in culture medium 

 containing soldier fly larvae. Neither this experiment nor the previous 

 one (Fletcher et al., 1956) haa treatment repetitions and discrepancies 

 do exi s t . 



In the field, it was shown that H. illucens larvae will replace 

 M. domestica larvae in poultry manure if the manure is moistened (Furman 

 et al., 1959). It was also demonstrated that larval populations of H. 

 iVLuoens will develop successfully when the larvae are introduced under- 

 neath the crust of dry manure.
