Green lacewing for rose aphid
UC IPM names green lacewings among the natural enemies of rose aphid, but also says that releasing green lacewings against rose aphid has not been shown to give significant control in research trials. In most of California, UC IPM calls rose aphid a problem for only about six weeks in spring and early summer, until summer heat reduces the numbers. Hose colonies off, keep ants off the canes and let wild lacewings, hoverflies, lady beetles and parasitic wasps do the work.
