The percentage of insecticide varies in emul- 

 sifiable concentrates and wettable powders. 

 The accompanying chart shows how to prepare a 

 0.5-percent spray. To make a 1-percent spray, 

 double the amounts. To make a 2.5-percent 

 spray, multiply the amounts by 5. 



NORTHERN FOWL MITE 



Northern fowl mites, which look like chicken 

 mites, stay on the fowls. They congregate near 

 the vent, tail, and neck, and suck blood. Feath- 

 ers become soiled. Scabs often form on the skin 

 of infested fowls. 



Control 



Use malathion as a dust in litter for chickens 

 only. Apply 1 pound of 4-percent dust per 40 

 square feet of litter surface. Apply dust uni- 

 formly with a hand-operated plunger or rotary 

 duster or with a shaker jar. Repeat as neces- 

 sary. 



Apply a 1-percent malathion spray or a 4- 

 percent malathion dust directly to individual 

 birds or to flocks. Use 1 gallon of spray or 1 

 pound of dust per 100 birds. 



Nicotine sulfate (40-percent nicotine) or 3- 

 percent malathion emulsion may be used as a 

 roost paint. Apply 1 pint per 150 feet of roost 

 one-half hour before roosting time. Repeat as 

 necessary. 



SCALY-LEG MITE 



Scaly-leg mites burrow under the scales of 

 the fowls' feet and lower legs. The burrowing 

 causes itching and irritation. The scales are 

 pushed up from the legs, scabs or crusts form 

 around them, and they are easily detached. 



If untreated, the legs and feet become dis- 

 torted and some of the terminal joints of the feet 

 may be lost. 



Control 



Soak the fowl's feet in warm soapy water until 

 scales are loosened. Then grease lower legs 

 with lard containing 15 percent of sulfur (325 

 mesh) . 



Or — Dip or paint the feet and lower legs with 

 crude oil or with water emulsion containing 0.1 

 percent of lindane. (Kerosene is less effective 

 than crude oil.) Do not get oil on the upper 

 legs. One treatment is usually enough, but if 

 distorted scales are not shed within a month, 

 repeat the treatment. 



DEPLUMING MITE 



Depluming mites burrow into the skin and 

 cause an irritation at the base of the feathers. 

 In trying to relieve the irritation, fowls pull out 

 their feathers until they are almost naked.
