Patterns of host-plant utilization by leafhoppers in the genusEupteryx(Hemiptera: Cicadellidae) in Britain

Abstract

Known host-plant associations are listed for the 16 species of Eupteryx occurring in Britain. A total of 77 species in 17 plant families are exploited. The most frequently represented plant family is the Labiatae. Degrees of specificity range from strict monophagy (four spp.) to broad polyphagy (five spp.). In general, host-plant overlap between species is low. The detailed relationships between three Eupteryx species and three members of the Urticaceae were explored using field populations and laboratory feeding experiments, survival tests and examination of patterns of oviposition. Eupteryx urticae, E. cyclops and E. aurata all utilized Urtica dioica as their primary host plant. However, the only regularly recorded association with other members of the Urticaceae was the host range expansion of E. urticae onto Parietaria judaica in the second generation. These findings were supported by the laboratory experiments. The spatial distributions of E. urticae oviposition sites and levels of attack by mymarid parasitoids were similar in populations on the two plant species. The implications of these results are discussed.

Ligurian leafhopper Eupteryx decemnotata (Rey) (Insecta: Hemiptera: Cicadellidae: Typhlocybinae)

“…Members of the Typhlocybinae, the subfamily of leafhoppers to which the Ligurian leafhopper belongs, feed by piercing the leaves of their host plants with specialized, tube-like mouthparts (Stewart 1988). Multiple adults may be present on a single plant, which implies that some level of competition for feeding sites is tolerated among members of the same species.…”

Effects of Sage Leafhopper Feeding Damage on Herbage Colour, Essential Oil Content and Compositions of Turkish and Greek Oregano

“…The known host range of Eupteryx species was sweet balm ( Melissa officinalis L.), peppermint ( Mentha x piperita L.), catmint ( Nepeta cataria L.), Nepeta spp., basil ( Ocimum basilicum L.), marjoram ( Origanum majorana L.), oregano ( Origanum vulgare L.), rosemary ( Rosmarinus officinalis L.), sage ( Salvia officinalis L.), thyme ( Thymus vulgaris L) and Thymus spp. all in the family Labiatae (Maczey and Wilson, 2004; Nickel and Holzinger, 2006; Stewart, 1988; Wightman and Whitford, 1984).…”

“…Both nymph and adult feedings on green leaf parts cause economic damage. As far as is known, the sage leafhopper is exclusively associated with herbaceous plants, many of which are aromatic and cultivated for their culinary or medicinal properties (Le Quesne and Payne, 1981; Payne, 1981; Stewart, 1988; Wightman and Whitford, 1984). Sage leafhopper feeding adversely affects oregano growth and development and induces changes that affect market quality of the oregano.…”
