    Got lily leaf beetles? UConn needs your help

    Researchers at UConn are conducting a lily leaf beetle biological control project this summer and are seeking gardens in which to conduct research. Gardens must include a minimum of 12 plants in the lily family with lily leaf beetles feeding on them. As part of the project, the research team would like to collect lily leaf beetle larvae from May through August and introduce two species of beneficial parasitic wasps in June. The parasitoid wasps attack lily leaf beetle larvae, and over time these natural enemies will disperse from release sites and begin to spread through the state to reduce populations of lily leaf beetles. The wasps were introduced in Connecticut in 2012 and have been released in Maine, Massachusetts, New Hampshire and Rhode Island, where they are establishing and starting to impact lily leaf beetle populations. To participate, contact Gail Reynolds, Middlesex County master gardener coordinator, at gail.reynolds@uconn.edu or (860) 345-5234.
