apple aphid การใช้

• Apples are prey to unsightly cedar-apple rust, borers, woolly apple aphids and apple scab.
• The " MM " series was developed primarily to provide resistance to Woolly Apple Aphid ( Eriosomatinae ) infestation.
• The woolly apple aphid, " Eriosoma lanigerum " is a widespread pest of fruit trees, feeding principally on apple, but also, pears, hawthorn, ash, alders, elms and oaks.
• For example, the apple aphid ( " Aphis pomi " ), after producing many generations of wingless females on its typical food plant, gives rise to winged forms which fly away and settle on grass or corn stalks.
