Sustainable Pest Management

Japanese maple scale (JMS), (Lopholeucaspis japonica Cockerell) (Hemiptera: Diaspididae), is a prolific pest of major concern to nursery crop producers and landscape managers in MD and the eastern United States. JMS is difficult to monitor and manage due to its small size, extended crawler emergence periods, and wide host plant range. The purpose of this fact sheet is to provide practitioners with host plant information that will help to improve and focus their monitoring efforts. All plants listed in this fact sheet are verified as hosts of Japanese maple scale from published literature or direct observations by the authors. This list should not be considered all inclusive. Due to the generalist feeding habits of JMS there are likely more hosts we have yet to identify including additional cultivars/hybrids. Authors: Paula M. Shrewsbury, Nancy M. Harding, Marie S. Rojas, and Stanton Gill; Title: Japanese Maple Scale Woody Ornamental Host Plants (EB-1)

Vibrio bacteria naturally inhabit coastal waters and are frequently isolated from a variety of raw seafood, particularly oysters. Detection of Vibrio species in seafood and growing water has traditionally been problematic because of the limitations of conventional techniques based on plate culture methods. Moreover, no culture method is able to discriminate pathogenic populations. In order to provide education and training to individuals involved in seafood testing, a hands-on training course has been developed and offered through cooperative efforts of University of Maryland Extension (UME) and University of Maryland’s Joint Institute of Food Safety and Applied Nutrition (JIFSAN). The methods described in this manual are designed for detection and enumeration V. parahaemolyticus, V. vulnificus, and V. cholerae in oysters. The analytical methods are combination of procedures from the Food and Drug Administration (FDA) Bacteriological Analytical Manual (BAM) and other sources, and have been used as training protocols for the hands-on training course on Vibrio Detection.
