Drosophila Information Service Number 101 December 2018 Prepared at the Department of Biology University of Oklahoma Norman, OK 73019 U.S.A. ii Dros. Inf. Serv. 101 (2018) Preface Drosophila Information Service (often called “DIS” by those in the field), was first printed in limited copies in March, 1934. For those first issues, material contributed by Drosophila workers was arranged by C.B. Bridges and M. Demerec. As noted in its preface, which is reprinted in Dros. Inf. Serv. 75 (1994), Drosophila Information Service was undertaken because, “An appreciable share of credit for the fine accomplishments in Drosophila genetics is due to the broadmindedness of the original Drosophila workers who established the policy of a free exchange of material and information among all actively interested in Drosophila research. This policy has proved to be a great stimulus for the use of Drosophila material in genetic research and is directly responsible for many important contributions.” Since that first issue, DIS has continued to promote open communication. The production of this volume of DIS could not have been completed without the generous efforts of many people. Except for the special issues that contained mutant and stock information now provided in detail by FlyBase and similar material in the early annual volumes, all issues are now freely-accessible from our web site: www.ou.edu/journals/dis. For early issues that only exist as aging typed or mimeographed copies, some notes and announcements have not yet been fully brought on line. But we intend to fill in those gaps for historical purposes in the future. Individual requests for specific entries may be available from Jim Thompson, DIS Editor. We continue to encourage all researchers to consider submitting articles that use Drosophila for teaching as well as articles that report new techniques, research results, and interesting new mutations. In the interests of honoring the long-standing philosophy of open exchange of ideas, we sometimes accept articles that have unusual or limited perspectives. We thank the many contributors from around the world who sent material for this issue, and we invite your submissions for future annual issues as well as any suggestions you have for maintaining this as a useful Drosophila research community resource.

Genètica, Microbiologia i Estadística, Universitat de Barcelona, Barcelona (Spain). *Corresponding author: [email protected] A sample of drosophilids was obtained from the Font Groga site (Barcelona) on 8th May 2018. This site is on a hill (400 m above sea level) located at the edge of Barcelona city. The vegetation of the trapping place is mainly composed of pines (Pinus pinea) and ilexes (Quercus ilex) with Mediterranean brushwood (Arbutus, Ruscus, Erica, Hedera, Smilax, and others) (Araúz et al., 2009). Flies were collected from 17:15 to 17:45 pm using 12 baits containing fermenting bananas placed along a trail. The measures for several climatic parameters were obtained from a close meteorological station (Observatori Fabra). For this day, the recorded values were: Maximum temperature: 23ºC, Minimum temperature: 14ºC, and Rainfall: negligible. It was a cloudy and humid afternoon. Next day in the laboratory, collected individuals were classified according to species and sex (Table 1). Table 1. Classification of flies according to trapping time, species and sex (Font Groga site, Barcelona).

This result could be explained by the fact that spring is the season when this species presents its peak of expansion (Krimbas, 1993; Argemí et al., 2003).
