Zoology
Zaharia NECULISEANU under stones and logs, under back, on and in the soil and sandy. Immature stages of some species were collected from the field, while their eggs were obtained in the laboratory from field collected adults. Some species taken at light. In order to study their behavior, life cycle and type of reproduction many species, were grown in the laboratory (pair beetles). The adults and immature stages (larvae, pupae) collected in the field has been maintained in the containers and glasses with different diameter and deep with the soil from their habitats. The reproduction and life cycle for many species of some family were studied at temperature 25±3°C under laboratory condition. Collected material were preserved in 70% alcohol for further identification. Classification of the beetles are made after Lawrence and Newton (1995) and American Beetles (Arnett Jr. & Thomas (2000), and Arnett et al. (2002). The scientific works of Erwin (1974), Liebherr (1986), Noonan (1991), Bousquet, (2010) and Nomina Insecta Nearctica were used as the primary key to identify the majority of species. The following abbreviations are used in the text of this work: JBWR (Jamaica Bay Wildlife Refuge), LI (first instar), L2 (second instar), L3 (third instar). The Microscope MBS-9 (LOMO) was used for identification of species and separation by sex. Results and discussions In this study we identified the diversity and natural history of the beetles Pterostichini (Coleoptera, Carabidae) of the Jamaica Bay Wildlife Refuge. In the research periods in JBWR were collected 14 species of the tribe Pterostichini, which belong to 3 genera: Poecilus, Stereocerus and Pterostichus. Captured beetles of the genus Pterostichus were the most abundant, with a total of 11 species: Pterostichus castor Goul. and Bousq., Pt. caudicalis Say, Pt. commutabilis Motsch., Pt. corvinus Dej., Pt. ebeninus Dej., Pt. femoralis Kirby, Pt. melanarius 111. Pt. mutus Say, Pt. patruelis Dej., Pt. tenuis Cas., Pt. trinarius Cas. Genus Poecilus include 2 species: Poecilus chalcites 3 68 2 1 4
