Tree species effect on natural control of H. albipunctella de Joannis in a millet agroforestry system in Senegal

Association of several tree species in and around a plot can have a positive impact on ecosystem services. Thus, traditional agroforestry systems, characterized by a high plant diversity, constitute an ideal model of study to test if the natural tree vegetation provides both shelter and food resources for insects that could potentially improve biocontrol services. The main objective of this study was to test if tree species presence and diversity could enhance the natural regulation of the millet head miner Heliocheilus albipunctella (MHM) in agroforestry systems of the Senegalese Peanut Basin. To address our objective, we realized an inventory of tree species in a total of 30 millet fields surveyed in Bambey area, during 2013 and 2014 (Fig.1). These data were used to calculate indices related to the abundance and diversity of tree species. The natural regulation was estimated using the biocontrol service index (BSI) for each millet field. In addition, data on MHM egg and larval predation and parasitism rates were also collected to estimate biocontrol services. Statistical analysis of the effect of tree presence and diversity on natural regulation variables were tested using a linear regression. Surprisingly, we found that BSI decreased with tree diversity and that it increased with the presence of the tree species Faidherbia albida. Morever, the presence of Anogeissus leiocarpus enhanced MHM egg parasitism and the presence of Azadirachta indica favored MHM egg predation

Checklist of marine Crustacea Decapoda (excluded Brachyura) from Iberian Peninsula

An actualized and annotated checklist of marine Crustacea Decapoda (excluded Brachyura) from Iberian Peninsula and by sectors (Northern Spain (Gulf of Biscay to Galicia) - West Portugal - Gulf of Cádiz (S Portugal- SW Spain: Cape San Vicente to Gibraltar Strait) - Alborán Sea - Eastern Mediterranean Spain (Baleares-Levante)) is provided. Systematic changes and synonymies, new records, introduced species by anthropogenic activities and characterization of the spatial distribution of species are commented. In total 292 decapods species (not including Brachyura), belonging to 134 genera and 42 families, are cited along Iberian waters. Of these, 114 were not found by Zariquiey Álvarez (1968). The richest families are Paguridae, Hippolytidae and Palemonidae (with 28, 21 and 17 species respectively). By sectors, the Gulf of Cadiz shows the highest richness (178 species), consequence of the confluence of Atlantic and Mediterranean waters and of a greater depth range in this area (when comparing with the adjacent Alborán Sea sector). The total marine decapod species along Iberian waters (including crabs, Marco-Herrera et al., 2015) is, at least, 431. Also, other 13 freshwaters species have been cited in Iberian Peninsula.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Strategic Approach to Farming Success

This paper is an abstract of a new book for farmers launched on April 8, 2005 (Nell & Napier, 2005). The two authors, Wim Nell of South Africa and Rob Napier of Australia, have respectively 28 and 37 years national and international experience in strategic agricultural management. The book is written for farmers across the world and is dedicated to all farmers. The book takes the reader on a strategic journey to farming success, which consists of 11 stages. At the end of each stage the reader has the opportunity to answer some questions that will guide the process of compiling a strategic plan for a specific farming business. The book opens new horizons for the modern farmer to manage the farming business more successfully.Farming success, strategic approach, strategic farming, scenarios, holistic management., Farm Management,
