Tulip Poplar Aphids

Tulip poplar aphids are becoming active. These populations tend to grow for a couple weeks then crash as natural enemy abundance increases.  They are heavily parasitized and consumed by lady beetles. Note orange lady beetle eggs in the picture.  Thus treatment is typically not necessary though in some cases natural enemy populations may be insufficient due to urbanization or other stresses. Aphid management is described here.

I am broadly interested in the ecology and management of arthropod pests. Herbivorous arthropods cause extraordinary damage to plants in agricultural, urban, and natural ecosystems. Understanding interactions between pests and their environment, plant hosts, and natural enemies can improve management practices and reduce pesticide applications.
