Pay particular attention to the animal's legs and undersides when spraying. For dry stock 

 and young stock on pasture, use a 1-percent Ciodrin, water-diluted spray. Apply 1 to 2 

 pints per animal, as often as once per week if needed. Ciodrin is the most-effective 

 insecticide for face-fly control. All of the above insecticides provide good control of 

 horn flies and fair control of stable flies. 



For control on beef cattle, apply a water-base spray of 0.5-percent toxaphene, using 1 to 

 2 quarts per animal every three weeks. Toxaphene provides excellent control of horn flies, 

 fair control of stable flies, and poor control of face flies. 



If face flies become serious, use Ciodrin as suggested for dairy cattle. A canvas or 

 burlap head-oiler or back-oiler, saturated with 5-percent toxaphene in oil, will provide 

 some relief against face flies. Do not apply toxaphene to beef cattle within 28 days of 

 slaughter. 



HOMEOWNER INSECT PROBLEMS 



Mimosa webworm larvae can be found feeding on honey locust and mimosa in the southern 

 sections of the state. Within the next week or two, they should become apparent in the 

 central and northern sections. They are small, gray -to -brown, striped, active cater- 

 pillars that use a silken thread to tie a bunch of leaflets together. They skeletonize 

 these leaflets and then form a new nest. The old nest turns brown, and the leaflets 

 die. Several generations will follow this first one. Treatments made now in the southern 

 sections and during the next week or two in the central section will help prevent more- 

 severe damage by this insect later in the summer. However, an additional treatment in 

 late July and August may still be needed. 



\ spray of either carbaryl (Sevin) using 2 pounds of 50 -percent wettable powder per 100 

 gallons of water or malathion using 1 quart of the 50- to 5 7 -percent liquid concentrate 

 per 100 gallons of water is effective. 



First-generation elm leaf beetles are skeletonizing the leaves of Chinese and other elms 

 in the central and northern sections. The damage by first -generation worms is about over 

 in the southern part of the state. These small, dirty-yellow to black worms feed on the 

 undersides of leaves and congregate in large numbers next to the trunk at ground level 

 vhen they are ready to pupate. A spray of carbaryl (Sevin) or malathion is effective. 

 Spray treatment may be needed again in late July in southern sections to control second- 

 generation worms . 



•latching and feeding by cottony maple scale is beginning on the leaves of soft maple and 

 3ther trees and shrubs. A sign of infestation is the appearance of white cottony masses 

 (like popcorn) on small twigs and branches . The female scale has laid hundreds of eggs in 

 -hese cottony masses. Apply control measures within the next week or two. The young 

 scales must be killed before they develop a protective covering. A malathion spray is 

 effective . 



Bagworm hatch is now complete in northern sections, and the larvae are feeding on ever- 

 greens and other trees and shrubs. Sprays should be applied immediately for best results. 

 Jse carbaryl, malathion, or diazinon. Follow the directions on the label. In central 

 uid southern sections, it is still not too late to spray shrubs for protection against 

 pagworms.
