Cinara Cupressivora W Atson & Voegtlin, 1999 Other Scientific Names: Order and Family: Hemiptera: Aphididae Common Names: Giant Cypress Aphid; Cypress Aphid
O R E ST E ST PE C IE S R O FIL E F P S P November 2007 Cinara cupressivora W atson & Voegtlin, 1999 Other scientific names: Order and Family: Hemiptera: Aphididae Common names: giant cypress aphid; cypress aphid Cinara cupressivora is a significant pest of Cupressaceae species and has caused serious damage to naturally regenerating and planted forests in Africa, Europe, Latin America and the Caribbean and the Near East. It is believed to have originated on Cupressus sempervirens from eastern Greece to just south of the Caspian Sea (Watson et al., 1999). This pest has been recognized as a separate species for only a short time (Watson et al., 1999) and much of the information on its biology and ecology has been reported under the name Cinara cupressi. Cypress aphids (Photos: Bugwood.org – W .M . Ciesla, Forest Health M anagement International (left, centre); J.D.

Their bodies are sometimes covered with a powdery wax. They typically occur in colonies of 20-80 adults and nymphs on the branches of host trees (Ciesla, 1991). -

Contributions to the Life-History of Tetraclinis Articu- Lata, Masters, with Some Notes on the Phylogeny of the Cupressoideae and Callitroideae
Contributions to the Life-history of Tetraclinis articu- lata, Masters, with some Notes on the Phylogeny of the Cupressoideae and Callitroideae. BY W. T. SAXTON, M.A., F.L.S., Professor of Botany at the Ahmedabad Institute of Science, India. With Plates XLIV-XLVI and nine Figures in the Text. INTRODUCTION. HE Gum Sandarach tree of Morocco and Algeria has been well known T to botanists from very early times. Some account of it is given by Hooker and Ball (20), who speak of the beauty and durability of the wood, and state that they consider the tree to be probably correctly identified with the Bvlov of the Odyssey (v. 60),1 and with the Ovlov and Ovia of Theo- phrastus (' Hist. PI.' v. 3, 7)/ as well as, undoubtedly, with the Citrus wood of the Romans. The largest trees met with by them, growing in an un- cultivated state, were about 30 feet high. The resin, known as sandarach, is stated to be collected by the Moors and exported to Europe, where it is used as a varnish. They quote Shaw (49 a and b) as having described and figured the tree under the name of Thuja articulata, in his ' Travels in Barbary'; this statement, however, is not accurate. In both editions of the work cited the plant is figured and described as ' Cupressus fructu quadri- valvi, foliis Equiseti instar articulatis '. Some interesting particulars of the use of the timber are given by Hansen (19), who also implies that the embryo has from three to six cotyledons. Both Hooker and Ball, and Hansen, followed by almost all others who have studied the plant, speak of it as Callitris qtiadrivalvis. -

Highlights • The employment of ISSR molecular markers has shown moderate genetic diversity and high genetic differentiation in Tetraclinis articulata. • Genetic structure of populations seems to be influenced by the anthropogenic use of this species since historical times, or alternatively, by the complex palaeogeographic history of the Mediterranean basin. • Results could be used to propose management policies for conservation of populations. Abstract Tetraclinis articulata (Vahl) Masters is a tree distributed throughout the western Mediterranean basin. It is included in the IUCN (International Union for Conservation of Nature) red list, and protected by law in several of the countries where it grows. In this study we examined the genetic diversity and genetic structure of 14 populations of T. articulata in its whole geographic range using ISSR (inter simple sequence repeat) markers. T. articulata showed moderate genetic diversity at intrapopulation level and high genetic differentiation. The distribution of genetic diversity among populations did not exhibit a linear pattern related to geographic distances, since all analyses (principal coordinate analysis, Unweighted pair group method with arithmetic mean dendrogram and Bayesian structure analysis) revealed that spanish population grouped with Malta and Tunisia populations. -

Proposal To list the species Widdringtonia whytei in CITES Appendix II without annotation specifying the types of specimens to be included, in order to include all readily recognizable parts and derivatives in accordance with Resolution Conf. 11.21 (Rev. CoP17). On the basis of available trade data and information it is known that the regulation of trade in the species is absolutely necessary to avoid this critically endangered species, with major replantation efforts underway, becoming eligible for inclusion in Appendix I in the very near future.

Overview Widdringtonia whytei or Mulanje cedar, the national tree of Malawi, is a conifer in the cypress family endemic to the upper altitude reaches of the Mount Mulanje massif (1500-2200 a.s.l.). This highly valued, decay- and termite-resistant species is considered to be “critically endangered” by the International Union for Conservation of Nature (IUCN) Red List of Threatened Species after years of overexploitation from unsustainable and illegal logging combined with human-induced changes to the fire regime, invasive competing tree species, aphid infestation, and low rates of 1 This document has been submitted by Malawi. -

A study was conducted for the first time under controlled conditions in order to assess the effects of temperature and light on germination and viability of W. whytei seeds. Seeds incubated at a constant temperature of 20 °C attained the highest cumulative germination percentage (100%) followed by 87% germination under fluctuating temperatures of 15 °C night/25 °C day. No seed germination occurred at temperatures below 15 °C. Seeds that failed to germinate at temperatures below 15 °C showed the highest (N90%) viability compared to the seeds incubated at 25 °C (60%). Across temperature regimes, germination was significantly higher under light (44.7%) than dark (35.6%) conditions. It is concluded that temperature is one of the critical factors for germination of W. -
