1. Biological species problems in some Tetramesa (Hymenoptera, Eurytomidae)

Author:

Ammophila arenaria; Calamagrostis epigejos; Elymus repens; Tetramesa; adults; biological speciation; gel electrophoresis; host preferences; larvae; pupae; starch
Abstract:
... Using horizontal starch gel electrophoresis, ten enzyme systems were surveyed in ten populations of Tetramesa reared from eight species of grass collected from different sites in Britain. Eight species of Tetramesa were recognized on the basis of the number and relative mobilities of electromorph bands for larvae, pupae and adults. No differences were found between populations of T. hyalipennis (W ...

Abstract:
... We examined the occurrence of vertically via host seeds transmitted endophyte infections of 14 grass species in natural populations in Finland and totally 97 agricultural cultivars of 13 grass species. Although endophyte infections were widespread in native grass species, overall endophyte occurrence and frequencies were lower than published reports have suggested. In natural populations, 10 out o ...

Abstract:
... Interest in organic farming is growing rapidly in Europe. The resulting expansion of the organic farming area has been expected to enhance the biodiversity of agricultural habitats. Organic cropping practices can be hypothesized to support a higher number of weed species than conventional cropping and also to favor herbicide-susceptible and less-nitrophilous species. The diversity and species comp ...

In the British Isles, there are 37 recorded species, all of which feed on grasses as larvae and are largely host specific. Some form galls on their hosts; others do not. We used a range of enzyme and random amplified ...

Abstract:
... Elymus repens (L.) Gould (2n = 6x = 42, StStStStHH) is a hexaploid perennial wheatgrass species from the tribe Triticeae, distantly related to bread wheat Triticum aestivum L. (2n = 6x = 42, AABBDD). As a potential source of resistance to Fusarium head blight (FHB), E. repens was crossed to common wheat to transfer resistance genes. The progeny were advanced to homozygosity by single seed descent. ...

Abstract:
... Direct drilling is one of the methods to reduce tillage costs. Low labor intensity of this system also makes it possible to grow crops in locations where it is a problem to maintain optimal sowing time. However, the use of no-tillage can cause increased weed infestation of crop plants and as a consequence a decline in crop yields. The present study investigated the effect of two tillage systems, p ...

However, benefits can also be substantial if the plant can attain resources from a large area. Thus, both the growth ...
