13- Although northern fowl mites do not significantly affect egg 

 production, nonsignificant decreases in production due to mites may 

 result in significant reductions in farm profits. 



}h. Application of acaricides can cause temporary nonsignificant 

 drops in egg production that result in monetary losses. Hens in the 

 latter part of the laying cycle may not be able to regain a rate-of-lay 

 high enough to recover these losses. More research is needed in this 

 area . 



15. Mite populations do not affect the immediate production level 

 of hens. However, the affects of present mite populations may be re- 

 flected by nonsignificant changes in egg production 6 to 8 weeks in the 

 future .
