September 1998 Die Weinzygaene Theresimima ampellophaga (BAYLE-BARELLE 1808) (Lepidoptera, Zygaenidae, Procridinae) Kehrt ein verschwundener Weinschädling zurück?* Gerhard M. TARMANN Abstract: The Vine Bud Moth or European Grapeleaf Skeletonizer Theresimima ampellophaga (BAYLE-BARELLE 1808) - reappearence of a vine pest? The Vine Bud Moth or European Grapleaf Skeletonizer Theresimima ampellophaga (BAYLE- BARELLE 1808) was thought to be under control for many years. The last harmful infestations are recorded from Hungary in 1954 (ISSEKUTZ 1957a, 1957b). Only a few records are known from later years. A possible reason for the decline of populations may be found in more effective use of pesticide and insecticide. In 1990 Th. ampellophaga was rediscovered on Crimea (Ukraine) after almost 50 years of absence (EFETOV 1990b). For the first time the larvae were found on decorative vines (Parthenocissus). Between 1990 and 1997 the Vine Bud Moth spread all over southern Crimea and has developed very strong populations. This fact leads to the conclusion that neighbouring countries might be in immediate danger. The present paper gives an overview about historical and recent observations of Th. ampellophaga with special emphasis to the situation on Crimea. Pheromone recognition and pest control methods are mentioned. The systematic position and the historical and recent geographical distributions are discussed.

PART I SPHINGES AND BOMB WITH EIGHT PLAJOES 0;cfor5 AT THE CLARENDON PRESS 1892 PRINTED AT THE CLARENDON PRKSS EY HORACE HART, PRINT .!< TO THE UNIVERSITY PREFACE At the request of Professor Westwood, and under the orders and sanction of the Delegates of the Press, this work is being produced as a students' handbook to all the Eastern Moths in the Oxford University Museum, including chiefly the Walkerian types of the moths collected by Wal- lace in the Malay Archipelago, which for many years have been lost sight of and forgotten for want of a catalogue of reference. The Oxford University Museum collection of moths is very largely a collection of the types of Hope, Saunders, Walker, and Moore, many of the type specimens being unique and of great scientific value. All Walker's types mentioned in his Catalogue of Hetero- cerous Lepidoptera in the British Museum as ' in coll. Saun- ders ' should be in the Oxford Museum, as also the types of all the species therein mentioned by him as described in Trans. Ent. Soc, Lond., 3rd sen vol. i. The types of all the species mentioned in Walker's cata- logue which have a given locality preceding the lettered localties showing that they are in the British Museum should also be in the Oxford Museum. In so far as this work has proceeded this has been proved to be the case by the correct- vi PREFACE.

PRINTERS. 1917. 4/. «/e^^i-^<^ "^ t^X^h^^ kf^i^^ ? TRANSVAAL MUSEUM ^'^ CHECK- LIST — OF — The South African LEPIDOPTERA HETEROCERA By A. J. T. JANSE. The first attempt to catalogue the iSouth African moths was made by Sir George F. Hampson in the Annals of the South African Museum, but unfortunately this work was not completed and is now about fifteen years old. Since then many additions have been made to the fami- lies treated in the above mentioned work ; most species have been described in the various journals, annals and periodicals and in the " Catalogue of the Lepidoptera Phalaena in the British Museum." It was therefore thought that a list of our moths would be welcome to the workers on South African Heterocera, especially for help in the arranging of collections and as a reference to the principal literature on the subject. Only the original descriptions have been cjuoted, as fuller information would have extended the work far beyond the limits of a check-list. For the same reason only such species have been included as have been actually recorded from South Africa or have been found by myself to belong to this fauna. My observation on the localities was not only based on my own extensive collection, but I had free access to the collections of several South African Museums and to those of many private collectors. The South African Heterocerous fauna is not sharply defined, and I have no doubt that many Central African species will be recorded from South Africa when the Wes- tern and Northern parts of our sub-continent have been bet fer explored.

A-1 Introduction A majority of the organisms present in natural areas are insects. Despite their numerical dominance, insects have been almost totally ignored by conservationists and natural area managers in the Midwest. This is especially unfortunate since insects, as annual species, are considerably more susceptible to the deleterious effects of natural and anthropogenic stresses than are organisms such as long-lived plants. Years of fire suppression, grazing, and general abuse have resulted in a degraded and somewhat depauperate flora in many sections of Savanna Army Depot (SAD) (see Bowles 1992).
