“…Common in both generations on Lamium album (1, 33,34,39) and other labiates that are cultivated as herbs or medicinal plants, such as Nepeta spp. (1, 22,33,38), Melissa officinalis (1,8,31,47) and Salvia officinalis (1,22,27,31,47). High densities in the second generation on potatoes (Solanum tuberosum) (1,14,(18)(19)(20)23,26,27,33,39,48), where it is frequently accompanied by E. aurata, and sugar beet (Beta spp.)…”

“…Primary host plant is Urtica dioica, to which it is usually confined in the first generation (1, 21,23,[25][26][27][41][42][43]45,48), although large overwintering populations occasionally recorded on Eupatorium cannabinum (1,38). Largest populations on U. dioica found at open sites (1, 10,44).…”

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.

Alternative approaches suggested for modeling multiseries of water resources systems are reviewed and compared. Most approaches fall within the general framework of multivariate ARMA models. Formal modeling procedures suggest a three‐stage iterative process, namely: model identification, parameter estimation and diagnostic checks. Although a number of statistical tools are already available to follow such modeling process, in general, it is not an easy task, especially if high order vector ARMA models are used. However, simpler ARMA models such as the contemporaneous and the transfer‐function models may be sufficient for most applications in water resources. Two examples of modeling bivariate and trivariate streamflow series are included. Alternative modeling procedures are used and compared by using data generation techniques. The results obtained suggest that low order models, as well as contemporaneous ARMA models, reproduce quite well the main statistical characteristics of the time series analyzed. It is assumed that the same conclusions apply for most water resources time series.
