El cultivo de frutos rojos supone un motor económico y social en el suroeste de España. Concretamente, en la provincia de Huelva se producen más del 80% de este tipo de frutos a nivel nacional. Sin embargo, en la Península Ibérica, no existen precedentes que estudien el estado de la biodiversidad y los factores que la afectan en este tipo de cultiv...

Con la introducción de la bacteria fitopatógena Xylella fastidiosa Wells en Europa, los sistemas productivos leñosos están amenazados, pudiendo ocasionar grandes pérdidas económicas y medioambientales. Los insectos que se alimentan del xilema de las plantas son los vectores potenciales de la bacteria. En Europa, se han detectado a Philaenus spumari...

Drosophila suzukii (Matsumura, 1931) is an invasive pest from South-East Asia that can damage a wide range of soft-skinned fruit crops (especially berries) resulting in serious fi nancial losses. At present, control of D. suzukii is still mainly based on adult-oriented chemical pesticides that is likely to result in resistance and environmental poll...

Over the last decades, expansion and intensification of agriculture have prompted a loss of biodiversity and ecosystem services in agrosecoystems. In order to mitigate these effects, organic farming is one of the main agri-environment schemes proposed for biodiversity conservation and sustainability. In the present work, richness and abundance of s...
Article
Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) was detected in 2008 in southern Europe and North America and it has spread rapidly throughout the two continents mainly affecting thin-skinned berries and stone fruits which constitute an important, economic and social driver in these regions. This study analyzes the potential control ability...

Larvae were collected in two areas of dehesa named “Viñuela Alta” and “La Rozuela”, located in Córdoba, southern Spain, from March to May (during defoliating Lepidoptera attacks) by beating holm oak branches with a two-and-a-half metre rod. Results obtained since the year 2000 showed that defoliation in Quercus ilex was caused by a wide diversity o...

Drosophila suzukii (Matsumura, 1931) is an invasive pest from South East Asia that was detected for the first time in Southern Europe in 2008. This species can damage a wide range of soft-skinned fruits crops affecting ripening fruits and causing important economic losses. Since the exclusive use of chemical insecticides for controlling D. suzukii...

Japanese plum Prunus salicina Lindl offers good expectations for their crop in organic management in the Valley of the Guadalquivir because of its rusticity and low chilling requirements. Control of pests and diseases represents, together with nutrient requirements, one of the challenges most relevant to this production system, which is more limite...

Intraguild predation (IGP) among predatory arthropods can impair pest control efforts and endanger the joint-action compatibility of groups of natural enemies. The present study used plant microcosms to examine IGP of Cheiracanthium pelasgicum (C. L. Koch) (Araneae: Miturgidae) on minute pirate bugs Orius laevigatus (Fieber) (Hemiptera: Anthocorida...
Article
Chemical and other selective insecticides are annually used as foliar treatments against defoliating Lepidoptera in the southern Spanish open woodland (known as dehesa), one of the largest forest ecosystems in the Mediterranean basin. In order to analyse the negative impact of these treatments on beneficial arthropods, the toxic effect of the three...
Article
Antagonist interactions such as intraguild predation (IGP) or cannibalism among predatory arthropods can reduce the impact of these invertebrates on pest limitation in agroecosystems. Here, the effects of intraguild predation between two major natural enemies of cotton pests, the cursorial spider Cheiracanthium pelasgicum (C.L. Koch) and the common...
Article
The relative feeding rates and preferences of a hunting-spider assemblage inhabiting southern Spanish cotton fields for two major cotton pests, Helicoverpa armigera (Hübner) and Spodoptera littoralis (Boisdubal) (Lepidoptera: Noctuidae), were analyzed under laboratory conditions. First, a no-choice feeding test was used to determine relative feedin...

The toxicity of nine Bacillus thuringiensis Cry proteins against neonate Earias insulana larvae was tested using a mixture of crystals and spores. The mean lethal concentration (LC50) of Cry1Ac was 1.99 μg/ml. Cry1Fa, Cry1Ca, Cry1Ja and Cry2Aa were more active than Cry1Ac, with LC50 values of 0.22, 0.24, 0.29, 0.43 μg/ml, respectively. Cry1Da and C...

Local species abundance is related to range size, habitat characteristics, distribution type, body size, and life-history variables. In general, habitat generalists and polyphagous species are more abundant in broad geographical areas. Underlying this, local abundance may be explained from the interactions between life-history traits, chorological...

The activity of six Bacillus thuringiensis (Berliner) Cry proteins against third-instar Prays oleae (Bernard) larvae was examined. Five of the toxins tested (Cry1Aa, Cry1Ab, Cry1Da, Cry1Ja and Cry2Aa) proved active against P. oleae, the highest larval percentage mortality being obtained with by Cry2Aa and Cry1Ja. LC50 values were 0.12, 1.2 and 6.17...

Most studies on the family Noctuidae focus on very few species that cause damage to crops; however, there is little information on the biology and ecology of the remaining species of noctuid moths. This work examines the relationship of the larvae of Cucullia calendulae with their main food plant Calendula arvensis. The results showed that the larv...

The microlepidopteran Prays oleae is one of the main insect pests causing significant crop losses in the Mediterranean olive groves. Bacillus thuringiensis based insecticides are being successfully used to minimize the impact of the second and third generations of this pest. However, because of its very small size and difficulty of rearing, very fe...

Under a general context dominated by quick and frequent changes (e.g. in agriculture intensification, climate, land uses), knowing how different drivers of change affect the performance of productive systems is prevailing. It is then basic to analyse how these changes influence biodiversity and their ecosystem services. Vineyards are one of the oldest agricultural systems in the Mediterranean region. This systems are linked to a narrow and old relationship between human management and natural surrounding environments, with a high social, economic and environmental interests. BACO wants, from an innovative and multidisciplinary perspective, to evaluate the role of climate, landscape and management on biodiversity and ecosystem services linked to vineyards. Within this framework, it proposes the following objectives: i) characterize the landscape, environment, climate and type of management of the main vineyards in the region; ii) evaluate the influence of landscape, environment and management on the biodiversity linked to vineyards and iii) estimate the ecosystem services that this biodiversity provides, together with their economic value.
