Field test. The baits described above plus Golden Malrin without 

 Muscamone were tested in the field with and without the addition of 

 Lure'em II attractant supplied by Farnam. Golden Malrin with Muscamone 

 was used as a standard. When baits were tested alone, 5 g were used. 

 When tested with the attractant, 5 g of bait and 3 g of the attractant 

 were used together. The Lure'em II attractant was never used in the 

 same bait station with Golden Malrin with Muscamone. 



Resul ts. Treatment means by treatment are shown in Table kj> and 

 Figure 37- Treatment means by sex are shown in Table kk and Figure 38. 

 Raw data is in Appendix 3. Kill'em Fly Killer II plus Lure'em II 

 attractant killed a significantly greater number of flies than the 

 other treatments including the Golden Malrin with Muscamone standard 

 (Table A3, Figure 37). Treatment means for Kill'em Fly Killer II plus 

 Lure'em II attractant and Kill'em Fly Bait plus Lure'em II attractant 

 were 158.25 and 116.13 flies per bait station respectively. All other 

 means were less than 30.0 flies per bait station (Table 43). 



Lure'em II attractant improved the kills of all baits except SX-70 

 Fly Bait. Golden Malrin without Muscamone plus Lure'em II attractant 

 killed a significantly greater number of flies than the Golden Malrin 

 with Muscamone standard. Kills produced by the standard bait were 

 numerically lower than all other kills except those of Kill'em Fly 

 Killer (Table k3) . 



Kill'em Fly Killer killed males and females of M. domesti-ca in 

 equal numbers (Table kk, Figure 38), but all other baits killed more 

 females than males. Three baits killed significantly greater numbers 

 of females than males. Lure'em II attractant increased the catches of 

 females for all baits except SX-70 Fly Bait. Golden Malrin without
