Abstract

HERMS, D.A. 1986. Pest-free honeylocust is a thing of the past. Am. Nurseryman 163(10):73-78.

Once considered pest-free, honeylocust has been touted as a replacement for the diseased-ridden American elm. Now it is one of the most common components of the urban forest. But, with popularity, honeylocust has also acquired problems with pests. It gained wide acceptance during the past 35 years, following the development of thornless and fruitless cultivars. Claims that honeylocust transplants easily and is tolerant of a wide range of environmental conditions, including salt contamination and drought have undoubtedly contributed to its popularity. Despite its reputaion of being pest-free, honeylocust developed problems with several serious native and introduced pests as it became common in the landscape. They include honeylocust plant bug (Diaphnocoris chlorlnonis), mimosa webworm (Homadula anisocentra), honeylocust spider mite (Eotetranychus multidigitull), honeylocust pod gall midge (Daslneura gleditschiae), and honeylocust borer (Agrllus difflcilis).
