of clear water as .1 syringe is one of the most effective control measures. 

 An infestation of red spider mite in the advanced stages will be well 

 covered with webbing, but even this webbing can be syringed off with 

 little difficulty. Syringing the plant with a iet of water helps in ridding 

 the plant oi both eggs and adults. Red spider mites are quite trouble- 

 some on morning glories and vines which are not easily washed. This is 

 a good argument for not growing them in the home.

Cyclamen mites are also troublesome on some house plants, especial- 

 lv African violet, geranium, and some of the begonias. The signs of 

 their presence are usually curled leaves, extreme hairiness on the young- 

 er leaves of the African violet, and deformed younger leaves and shoots 

 on begonia and geranium. Commercially, cyclamen mite may be con- 

 trolled by fumigants. but under house conditions our best bet is to pre- 

 vent spread from infested to healthy plants. This spread is accomplished 

 by handling or by contact of the two plants. 



As plants seldom outgrow the iniury or damage from cyclamen mite, 

 it is best to discard any plants that become infested and start over with
