plus 0.25-percent dichlorvos. Crotoxyphos applied as a 1-percent, water-diluted spray 

 at 1 to 2 pints per animal once a week is also effective. In addition, a 1-percent di- 

 chlorvos (DDVP) or a 0.1 -percent pyrethrum spray applied at 1 to 2 ounces per animal 

 each day provides fair control. When spraying pay particular attention to the animals' 

 legs and undersides . All of the above insecticides provide good control of horn flies 

 and fair control of stable flies. 



For beef cattle, apply a water-base spray of 0.5-percent toxaphene at the rate of 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. An automatic spray- 

 er using crotoxyphos in oil will provide the best control. 



HOMEOWNER PROBLEMS 



Sod webworm moths are now present in numbers in lawns, and egg-laying has started. If 

 you notice many small moths flying over your lawn, you may want to apply diazinon or 

 carbaryl as a control for the larvae which will soon hatch from the eggs. Insecticide 

 applications should start in about a week. Water and cut the lawn before applying the 

 insecticide. A good fertility program may help overcome the webworm damage. 



Willow aphids are dark red or dark brown and can be found in clusters on the twigs of 

 weeping willow and other willow species. Malathion provides excellent control. 



Cabbage loopers are now present in numbers on all members of the cabbage family, such 

 as broccoli, brussel sprouts, cabbage, and cauliflower. Apply Dipel, Biotrol, or Thur- 

 icide. These biological control sprays have provided excellent "cabbage worm" control 

 this summer. 



MAILING INSTRUCTIONS FOR INSECT SPECIMENS 



When sending insect specimens to us for identification, place them in a small vial, 

 wrap the vial, and put it in another package. Insects on Scotch tape or loose in en- 

 velopes become so mutilated that identification is almost impossible. 



Do not put live insects in the mailing container; when the top is taken off, the in- 

 sect escapes. Flies are particularly difficult to catch once they are flying around 

 in our office and our fly swatter may mutilate them. Please confine the insect in an- 

 other container before putting it in a mailing tube.
