( 1 377) tested compounds attractive to house flies and found that 

 tr imethylamine and indole were the main house fly attractants. Baits 

 consisting of tr imethyl ami ne , indole, NhK CI , and linoleic acid were 

 significantly superior to commercial preparations containing (Z)-9 _ 

 tr icosene. 



Location of bait stations in and around poultry houses was found 

 to influence the size and sex ratio of the catches. Baits located in 

 the sunlight-shade border areas collected the greatest number of flies 

 (Will son and Muila, 1973). In bait stations near the center aisles, 

 females outnumbered males, but a one-to-one ratio was approached in 

 catches from the perimeters of poultry houses (Will son and Mulla, 1975). 

 Bait stations dominated by one sex had catches significantly lower than 

 those of stations conducive to both sexes. 

 Space sprays 



This brief review is limited to use of synthetic pyrethroids as 

 space sprays. in a study by Willis and Thomas (1975), pyrethroids gave 

 better results than the ronnel standard, and resmethrin gave better 

 results than alletnrin. In another study, ronnel was more effective 

 than resmethrin (Wilson et al., 1975). Other trials have shown that 

 resmethrin is effective as a space spray against house flies (Mathis 

 et al., 1972) and mosquitoes (Haskins et al., 197*0. Permethrin was 

 shown to have a knockdown 8 to 16 times faster than that of alletnrin, 

 and an LDj- n three and four times higher than those of mesrethrin and 

 synergized mesrethrin respectively (Lhoste and Rauch, 1976). 



Kissam and Query (1976) tested an automatic p i ped-aerosol system 

 that used a 0.7°o synergized pyrethrin solution for fly control in
