Aphids on trees and shrubs

This week I found clusters of aphids on my Knockout roses. This time of year lots of plants start getting aphid infestations. Most are short-lived though. Natural enemies accumulate quickly on aphid infested plants. I found a Japanese maple with a few small black aphids but there were already lady beetle eggs all over the bark and leaves.

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.
