LOCUST LEAF MINER (Xenochalepus dorsalis) caused browning of leaves of black locust in Knox and Greene Counties, INDIANA, and was reported abundant in the southeastern part of the State during the season. IMPORTED WILLOW LEAF BEETLE (Plagiodera versicolora) was troublesome in RHODE ISLAND, especially on weeping willow in the Providence area of Providence County during late May; and was severe on many weeping willows in all sections of MARYLAND during late June and July. Local, heavy infestations of a COTTONWOOD LEAF BEETLE (Chrysomela scripta complex) caused much defoliation in the Fort Valley area of Peach County, GEORGIA, and was extremely abundant on balsam poplar (Populus balsamifera) in the northern part of IDAHO during early June, with greatest infestations being encountered in the Spirit Lake area of Kootenai County. Defoliation by this pest was often severe. Anomoea laticlavia, which defoliated many honeylocusts in KANSAS during 1959 and 1960, particularly in nursery plantings, was reported only as scattered individuals during the 1961 season in that State; but adults of this species were abundant on honeylocust in a few spots in ILLINOIS during the year. SMALLER EUROPEAN ELM BARK BEETLE (Scolytus multistriatus) infestations that received treatments during the 1961 season in CALIFORNIA were very light.
