In this series are our most destructive species and those most difficult to deal with. Some of these scales are oviparous, laying eggs which winter under the protection of the scale; others are viviparous, wintering in the partly grown condi- tion. The "San Jose Scale" is an example of a viviparous form, and this may be reached in winter when the plants are dormant by caustics, like the lime and sulphur washes, or by penetrants, like the oil emulsions or soluble oils. The oviparous forms, like the "oyster shell scale" and "scurfy scale," cannot be satisfactorily reached in winter, but must be dealt with when the young larvas are moving in spring.
