Abstract The carnation tortrix moth, Cacoecimorpha pronubana (Hübner, [1799]) (Lepidoptera: Tortricidae), is one of the most economically important insect species affecting the horticultural industry in the UK. The larvae consume foliage, flowers or fruits, and/or rolls leaves together with silken threads, negatively affecting the growth and/or aesthetics of the crop. In order to understand the polyphagous behaviour of this species within an ornamental crop habitat, we hypothesized that different host plant species affect its life history traits differently. This study investigated the effects of the host plant species on larval and pupal durations and sizes, and fecundity (the number of eggs and the number and size of egg clutches). At 20°C, 60% RH and a 16L:8D photoperiod larvae developed 10, 14, 20 and 36 days faster when reared on Christmas berry, Photinia (Rosaceae), than on cherry laurel, Prunus laurocerasus (Rosaceae), New Zealand broadleaf, Griselinia littoralis (Griseliniaceae), Mexican orange, Choisya ternata (Rutaceae), and firethorn, Pyracantha angustifolia (Rosaceae), respectively. Female pupae were 23.8 mg heavier than male pupae, and pupal weight was significantly correlated with the duration of larval development. The lowest and the highest mean numbers of eggs were produced by females reared on Pyracantha (41) and Photinia (202), respectively. Clutch size differed significantly among moths reared on different host plants, although the total number of eggs did not differ. This study showed that different ornamental host plants affect the development of C. pronubana differently. Improved understanding of the influence of host plant on the moth's life history parameters measured here will help in determining the economic impact that this species may have within the ornamental plant production environment, and may be used in developing more accurate crop protection methodologies within integrated pest management of this insect.

The Elachista regificella complex (Elachistidae) is revised and considered to consist of three closely related species: E. regificella Sircom, presently only recorded from Great Britain, E. geminatella (Herrich-Schäffer), stat. rev. (= E. nieukerkeni Traugott-Olsen, syn. nov.) and E. tengstromi nom. nov. (= E. magnificella Tengström, 1848, nec Duponchel, 1843). The latter two species are widely distributed e.g. in Central Europe, the range of E. tengstromi extending to Japan. The species are diagnosed and illustrated. Life history records indicate that the species have, at least to some extent, different host plant preferences: Luzula sylvatica is recorded as the host plant of E. regificella and E. geminatella, of which the latter probably exploits other host plants as well. L. pilosa is the only known host plant of E. tengstromi in Europe, with further host plants recorded in Japan. Neotypes are designated for Elachista regificella Sircom and Poeciloptilia geminatella Herrich-Schäffer.

This article presents data on the rooting of green cuttings of the studied species of ornamental trees and shrubs in a greenhouse with a misting system. We accounted the number of days from planting to the root formation and the number of rooted cuttings for each replication during our performance. We studied the influence of root formation stimulants on the rooting rate of various types of ornamental deciduous, flowering and coniferous plants. The effect of application of root formation stimulants is confirmed by the formation of a high-quality root system that is superior in length to those that were vegetated without “Kornevin”. However, the use of root formation stimulants is not advisable on shrubby cinquefoil, common privet and common lilac “Mademoiselle Casimir Perier”, because there is practically no increase in the rooting rate of cuttings in these plant species, compared to the control plants.

Host Plant Relationships

Two lace bug genera, Baeochila Drake & Poor, 1937 and Idiocysta China, 1930 (Hemiptera: Heteroptera: Tingidae) are recorded from Japan for the first time, and two new species, B. horvathi sp. nov. and I. takarai sp. nov., are described. The former was collected from the vines of Hedera rhombea (Miq.) Bean (Araliaceae) and the bark of Trachycarpus fortunei (Hook.) H.Wendl. (Arecaceae) in suburbanized areas of Honshu, Shikoku and Kyushu, and the latter was collected from the leaves of Freycinetia formosana Hemsl. (Pandanaceae) in the laurilignosa ecosystem of the Ryukyu Islands. The distribution ranges and host plant relationships of the two new species are discussed. Keys to all species of the two genera and photographs of living individuals for the new species are also presented.
