Don't play host to cotton aphids this winter

摘要

Aphids, once considered only a secondary pest in cotton, are now emerging as a major problem in some growing regions. But growers should not wait until they have cotton in the ground to start thinking about aphid control. The time to start getting ontop of next season's aphid problem is now -- before you have one. Pest aphids in Australian cotton regions don't have a special overwintering form like the heliothis (Helicouerpa armigero) pupa. So where do cotton aphids go during the winter when the weather gets cooler and there are no cotton crops?
