Dedication This publication is dedicated to Cathy Heidenreich who was tragically killed in an automobile accident in December, 2014. Cathy put her heart and soul into her work, which included many hours on this guide. Funded in part by the New York State Department of Agriculture and Markets. The guidelines in this bulletin reflect the current authors’ best effort to interpret a complex body of scientific research, and to translate this into practical management options.

Ent. 54 (1 /2), 2005 New data on the sawfly fauna of Corsica with the description of a new species Pontania cyrnea sp. n. (Hymenoptera, Symphyta) A. D. LISTON & J. SPÄTH Abstract Records of 38 taxa of Symphyta collected recently by the authors in Corsica are presented. 15 identified species are additions to the known Corsican fauna. Pontania cyrnea sp. n. is described and compared with the morphologically similar P. joergcnseni ENSLIN. The family Xyelidae is recorded for the first time on the island. A total of 71 symphytan species are now known from Corsica. Introduction CHEVIN (1999) published a list of 56 species of sawflies and other Symphyta (woodwasps, orus- sids) from Corsica. His paper is based mainly on material made available to him by specialists in other insect groups who have collected there. He also included data on specimens from Corsica in the Muséum national d'Histoire naturelle (Paris), and mentioned a few taxa already recorded in papers by other symphytologists. The island had previously been visited by a single sawfly specialist, who examined only the leaf-mining species (BUHR 1941). In spring 2004 the junior author stated his intent to collect Symphyta in Corsica.

Introduction been assigned to them. The form on black raspberry is Orange rust is a disease of black berry and black caused by a fungus known as Arthuriomyces peckianus, raspberry. Purple raspberry may also become infected, while the form more common on blackberry is but red raspberry is resistant. This rust occurs in two known as Gymnoconia nitens. Orange rust is one of different forms with very similar symptoms. One the more serious diseases of susceptible brambles in form has a long cycle and affects mainly black the Northeast. It should not be confused with the late raspberry, and the other has a short cycle and affects leaf rust disease of red raspberries. mainly blackberry. Gymnoconia peckiana was the name originally given to the fungus that causes orange rust, but some morphological differences were eventually identified between the two forms, and now separate scientific names have Figure 2: Sporulation on lower leaf surface of black raspberry (June in New York) (provided by S. Jensen, Cornell University) Symptoms and Signs Lower leaf surfaces become covered with blister-like Figure 1: Symptoms on upper leaf surface of black raspberry masses of yellow-orange spores by late May or early (provided by S. Jensen, Cornell University) June. These spores serve to spread the disease to other plants. In addition, heavily infected leaves may die, and infected shoots will be weak, spindly and have very few, if any thorns.
