Abstract:
... Ants frequently prevent herbivores from damaging plants. In agroecosystems they may provide pest control services, although their contributions are not always appreciated. Here we compared the ability of eight ant species to prevent the coffee berry borer from colonizing coffee berries with a field exclusion experiment. We removed ants from one branch (exclusion) and left ants to forage on a secon ...

Abstract:
... Adult hoverflies feed on pollen, nectar and honeydews. Thus, the implementation of floristically diverse resources in agroecosystems can enhance biological control of pests by increasing populations of these natural enemies. The objective of this work was to study the effect of seven species of Asteraceae (Andryala integrifolia L., Anthemis arvensis L., Calendula arvensis L., Carduus tenuiflorus C ...

Abstract:
... The effects of an artificial diet on growth, development, reproduction and digestive physiology of Chrysopa septempunctata Wesmael were determined. The results showed that the reproduction was highly correlated with weights of females and activities of trypsin-like and chymotrypsin-like enzymes of C. septempunctata. The influences of diet on the digestive physiology such as digestive enzyme activi ...

Abstract:
... In nature, most species of Lepidoptera are attacked by parasitoids, and some species may be hosts for several parasitoid species. When hosts are parasitized by more than one female of the same species (=superparasitism) or females of different species (=multiparasitism), then intrinsic competition occurs for control of host resources. To reduce competition, some parasitoids are able to recognize t ...

Abstract:
... Corynebacterium striatum is often dismissed as a contaminant when cultivated from blood samples; indeed, it is a skin saprophyte that may therefore be introduced into the clinical specimen accidentally. Nevertheless, the organism can be responsible for true bacteraemias, and multidrug resistance spread among nosocomial strains is of increasing concern. Specific criteria for testing have not been d ...

Although the absence of intervening sequences (IVSs) within the 23S rRNA genes in Campylobacter lari isolates has been described, there are apparently no reports regarding correlations between the nucleotide sequences of 23S rRNA genes and erythromycin (Ery) susceptibility in C. lari isolates. Here, we determined the minimum inhibitory concentrations of 35 C. lari isolates [n = 19 for urease-posit ...
