Melbourne, B.A., Gullan, P.J. and Su, Y.N., I 997. Interpreting data from pitfall-trap sur­ veys: crickets and slugs in exotic and native grasslands of the Australian Capital Territory. A-lemoirs of the Musrn111 of Victoria 56(2): 361-367. We use data from a pitfall-trap survey of 23 grassland sites to examine the effect of grass­ land type on the abundance of crickets and slugs and to demonstrate the problems associated with interpreting data obtained by pitfall-trapping. The data presented here arc for four species of native cricket (Insecta: Orthoptera: Gryllidae: Bobi/la victoriae Otte and Alexan­ der, Te/eogryl/us commodus (Walker), Buangina ane111ba Otte and Alexander, Pteronemo­ bius arima Otte and Alexander) and five species of introduced slug (Gastropoda: Pulmonata: Limacidae: Deroceras reticu/atum (Mtiller), Lehmannia (Lehmannia) nycte/ia (Bourguignat). Limax maximus Linnaeus; Milacidae: Mi/ax gagates (Draparnaud); Arion­ idae: Arion intermedius Normand). The survey included three types of native grassland (Themeda, Stipa, Danthonia), two types of exotic grassland (Pha/aris, Avena), and two seasons (summer, autumn). In addition to the survey, the effect of habitat structure on the efficiency of pitfall traps was examined in a well-replicated field experiment. The exper­ iment was carried out in Themeda grassland, which was manipulated to create three levels of habitat structure. Habitat structure was found to aff ect pitfall-trap efficiency for crickets but not for slugs. We show that it is necessary to use knowledge of the effect of habitat structure on pitfall-trap efficiency for different species to allow confident interpretation of data from field surveys. Grassland type had a significant effect on the abundance of both crickets and slugs. Bobi//a l'ictoriae and T. commodus were both found to have high abundances in Pha/­ aris, an improved pasture. Slugs appear to be highly invasive of native grasslands.
