This study presents data from samples collected along the Tormes river basin (western Spain) during the years 1988, 1989 and 1996 and then stored at the University of Salamanca. As a result of a research stay, a total of 19 species belonging to 3 genera (Prosimulium, Metacnephia and Simulium) and 5 Simulium subgenera (Boophthora, Eusimulium, Nevermannia, Simulium and Wilhelmia) were identified after examining 64% of the stored material, representing 35% of the species known from Spain. In addition, 14 species are reported for the first time in 3 provinces in the study area. Further sampling of blackflies is foreseen in the near future in order to check if the blackfly fauna composition determined in samples collected during the last two decades of the 20th century has change...

Active ingredients, Fipronil and Imidacloprid, act through ingestion and contact as neurotoxics. Fipronil, a phenilpyrazole, has shown satisfactory results for control neurotoxic resistant insect strains. By the other side for Imidacloprid, a neonicotinoid molecule, has been reported effectivity against pest insects as Blattella germanica. The present paper shows an efficacy test comparison between Fipronil, Goliath gel ® (0.05%) and Imidacloprid, Max Force Prime® (2,15%). Tests were conducted with wild strains of Periplaneta americana collected in sewers, reared in laboratory, and being the effects of products conducted over nymphs and adults of both sexes. We measured feeding response with fresh bait, dry bait, and with food choice experiments. Results were statistically treated with JMP® and SPSS®.

The environmental conditions of our country, especially in eastern and southern regions, let the populations of this insect develop to enormous numbers with the risk to become a sanitary problem. Common treatments for control American Cockroaches in sewage systems involve the use of sprays over the inner walls of manholes, applying generously products with great residual properties. In recent past, treatments with organophospates like Diazinon and Chlorpyriphos provided good control under good control practices. Nowadays, under the regulation of the Biocide Directive 98/8/CE which affect all European countries, the number of active substances available is very restricted, and the most which are available, mainly pyrethroids, have low efficacy applied as sprays into sewers. New strategies must be develop, and baiting can get a preferencial place. This is based in properties like, nice e...

Several signincant characters are described and illustrated. Differences in the presence or absence of constrictions dividing the reservoir into a number of distinct regions, the number and position of the insertions of the venom gland ducts on the reservoir, the branching pattern of the venom glands, and in the evennes and distribution of the spiral thickenings of the reservoir and duct intima are discussed.

The results showed specific habitat requirements for pupation in Simulium (Boophthora) erythrocephalum (De Geer, 1776) and Simulium (Wilhelmia) equinum (Linnaeus, 1758), two of the six species studied regarding elevation and temperature. While the rest of the species showed a certain degree of ecological overlap, co‐occurrence was in general low, which suggested that antagonistic biotic factors may be important in structuring blackfly assemblages. In effect, biotic predictors explained a high proportion (50%–70%) of the variability in the abundance of the pupae of the most generalist blackfly species, although further studies are needed to disentangle the sign of interspecific interactions. At the landscape level, S. (W.) equinum and S. (W.) pseudequinum Séguy, 1921 breeding habitats were associated with the presence of pig farms, and S. (Simulium) reptans (Linnaeus, 1758) and S. (B.) erythrocephalum with the presence of cattle.

The malariogenic potential of a formerly endemic area of Spain was analyzed in present manuscript according to the epidemiological parameters of receptivity, infectivity and vulnerability. During a five years period (2005-2009) comprehensive larval surveys of anophelines and continuous analysis of imported malaria cases were conducted in a study region of about 23 260 km². The next seven potential malaria vectors were collected: Anopheles algeriensis, Anopheles atroparvus, Anopheles claviger, Anopheles maculipennis, Anopheles marteri, Anopheles petragnani and Anopheles plumbeus. The entomological results conclude that malaria receptivity is still high in different rural and hinterland regions where it is possible to find high densities of An. atroparvus. Moreover An. algeriensis was also com...

This study shows the interactions between Liriomyza and their hosts-plants found in three natural parks from the Community of Valencia for 6 of the 13 Liriomyza species (Diptera: Agromyzidae) cited from Spain as potential pests for agriculture: L. bryoniae (Kaltenbach, 1858), L. cicerina (Rondani, 1875), L. congesta (Becker, 1903), L. strigato (Meigen, 1830), L. brassicae (Riley, 1884), and L. trifolii (Burgess in Comstock, 1880). Three new interactions for science to L. brassicae and L. trifolii are recorded. The importance of these interactions lies in the potential of being able to act as plant reservoirs for development of pest species alternative to crops. Distribution of Lirfomyza species by botanical families and species, including the study of beta diversity for the studied biotopes, are showed.

A total of 2796 specimens belonging to 18 species were collected, nevertheless the 72.5 % of these finds includes only three of them (Cx. hortensis hortensis, Cx. pipiens and Cs. longiareolata). The adaptation capacity to a varied typology of water bodies together with the marked multivoltinism that characterizes their biotic cycles are postulated as two of the principal reasons that explain their abundances. The altitudinal distribution as well as some information about the bioecology of all the species captured are also exposed.
