Early applications, when the aphids are fully exposed and before they curl the leaves, are most effective. Systemic pesticides are required once leaf curling has occurred. Systemic insecticides will control the spread of this aphid in the tree and also protect against other leaf feeding pests. The table on this page indicates the dates and sites of the 1998 training seminars to certify apple pest scouts to conduct the trapping program required by the Brazilian government for exporting apples to Brazil. All apple pest scouts who will be conducting apple maggot trapping in orchards in which the fruit is intended to be shipped to Brazil, will be required to obtain certification to set, check, and record these site-specific traps.
Attendance is mandatory for all scouts and optional for exporters, packers, and growers.
Each meeting is planned to be completed within two hours. After one to two weeks under the influence of cool, relatively dry Canadian air masses with easterly flow across the state, major changes are in store for the Great Lakes region and much of the Midwest. Look for an area of scattered showers and imbedded thundershowers along a warm frontal boundary to move northward and eastward across the state during the day on Wednesday, May 13. Best chances for precipitation will be across northern sections of the state, although even there, area coverage will likely remain scattered. By late Wednesday, winds will shift to the south and transport warmer, more humid air into the state.
