Aphids are presently abundant on some hawthome trees. These insects are small, 

 green, soft-bodied, sucking insects that congregate on developing buds and leaves. 

 If the insects are numerous and control appears necessary, spray the foliage with 

 malathion (2 teaspoons of 50- to 57-percent emulsion concentrate per gallon of water) 

 or diazinon (2 teaspoons of 25-percent emulsion concentrate per gallon of water) . 

 This treatment will also control mealbugs if present.
