CONTRIBUTIONS TO THE KNOWLEDGE OF THE BEETLES FAUNA FROM BRASSICA NAPUS OLEIFERA L. CROPS IN THE REPUBLIC OF MOLDOVA Svetlana BACAL Institutul de Zoologie al Academiei de §tiinte a Moldovei, str. Academiei nr. 1, 2028 Chijinau, Republica Moldova, svetabacal@yahoo.com , Abstract: The purpose of this research was to identify the fauna of Coleoptera of rapeseed crop agroecosystems in Republica of Moldova. A total number of 33 species from 28 genera and 10 families were identified. The complex of Coleoptera typical for rapeseed crop including pest species were revealed. Keywords: Coleoptera, species diversity, culture of turnip rape. Introduction Beetles are an essential component of each biotope. Under the anthropogenic influence, an important part of natural ecosystems have been converted into agrocoenose, which led to changes in agrocoenose complexes structure and specific diversity of ground beetles. In Republic of Moldova, agricultural ecosystems constitutes 75.6% of the total surface. These include cereal, fruit, wine, vegetables, fodder and technical crops agro-fitocoenoses [2]. Technical crops are widely used in industry and food. One of the oilseed crops of great importance, cultivated in Republic of Moldova is culture of turnip rape. This is an early honey plant, which gives better yields on chernozemic soils, and is big consumer of nutrients from the soil [1]. The main purpose of this paper is to evidence the beetle fauna of the culture of turnip rape in various localities of the Republic of Moldova, of the potential pests of this crop. Financial support was provided by the program of bilateral cooperation between Republic of Moldova and Romania project No 10. 820. 04. 16/RoA. Materials and methods Faunistic material analyzed in this paper was collected from two lots of turnip rape in the center and south of the country (localities Bäcioi andTroita Nouä). For extraction of beetles were used soil traps type Barber (two draws of 10 traps in each group examined at an interval of 10 days) and entomological net (one sample of 50 in both groups of investigated lots). Collections were made in spring 2011. The material was determined according to external morphological characters [3]. Were analyzed 487 samples of beetles. MARI SI A, XXXI, p. 51-54
