Relationship Of

With the question of conformity or unconformity between the Lower Tertiary and Upper Cretaceous, there is associated a problem of great economic importance to New Zealand. The subject involves something more than a mere academic discussion. If conformity exists, then we have only one coal-bearing formation; but if unconformity, then we have two. I believe that both the stratigraphical and palæontological evidence is overwhelmingly in favour of the latter.

A New Species

Longicorn beetles of the New Zealand genus Coptomma Newman are associated with a wide range of both native and exotic tree genera and are of some economic importance in forestry and horticulture because they kill leading shoots and degrade sawn timber. In this paper, the genus is revised and its scope is redefined. The genus Navomorpha White is synonymised with Coptomma. Two species, N. textorium and N. philpotti, are synonymised with Coptomma lineatum (Fabricius). A new species, C. marrisi, is described for Coptomma. All known species are redescribed. As a result of this revision, the present number of species in Coptomma has increased to five: C.�variegatum, C. lineatum, C. sulcatum, C. sticticum and C. marrisi. A key to species is given. Terminalia of both sexes are illustrated and described. The phylogeny of species is analysed cladistically and the monophyly of the genus is confirmed. Coptomma is widely distributed on the North Island, South Island, Stewart Island and Three Kings Islands of New Zealand. Known biology is noted for each species. The distribution of each species is mapped and discussed.

Helminth Infections

Helminth parasites are of considerable medical and economic importance. Studies of the immune response against helminths are of great interest in understanding interactions between the host immune system and parasites. Effector immune mechanisms against tissue-dwelling helminths and helminths localized in the lumen of organs, and their regulation, are reviewed. Helminth infections are characterized by an association of Th2-like and Treg responses. Worms are able to persist in the host and are mainly responsible for chronic infection despite a strong immune response developed by the parasitized host. Two types of protection against the parasite, namely, premune and partial immunities, have been described. Immune responses against helminths can also participate in pathogenesis. Th2/Treg-like immunomodulation allows the survival of both host and parasite by controlling immunopathologic disorders and parasite persistence. Consequences of the modified Th2-like responses on co-infection, vaccination, and inflammatory diseases are discussed.

There is no need to point out to a meeting of this Association the great economic importance, particularly to New Zealand, of pasture grass, nor to refer to the advances that have been made in the management of grasses in their utilisation as food for domestic stock.

The three native frog species of New Zealand were examined for gastrointestinal helminth parasites. Leiopelma hamiltoni was uninfected. Leiopelma hochstetteri was parasitized by the nematodes Aplectana novaezelandiae n.sp. and Cosmocerca australis n.sp. (both Cosmocercidae: Cosmocercinae), and the digenean Dolichosaccus (Lecithopyge) novaezealandiae Prudhoe, 1972 (Telorchiidae: Opisthoglyphinae). Leiopelma archeyi was infected with Cosmocerca archeyi n.sp. The three new cosmocercid species are differentiated readily from congenerics in other parts of the world by caudal features of the males and the shape of the female tail. Cosmocerca archeyi differs from C. australis in the shape of the tail in both males and females, the lack of rosette caudal papillae in males, and the possession of an unusually robust ventral somatic musculature in females. Since the native frogs from New Zealand are believed to have been isolated since the Mesozoic, the presence in them of cosmocercids that fall readily into well-established genera confirms the antiquity of the subfamily Cosmocercinae.

Phoma Betae

Phoma betae is an economically important pathogen of red beet causing preemergence seedling damping, leaf spot and root rot. However, the pathogenicity of P. betae is unknown in New Zealand despite the economic importance of this pathogen. Twenty-five isolates were collected from a survey of red beet seed farms in Canterbury, New Zealand during 2016/2017 and three of these PB101 (from seeds), PB103 (from roots) and PB106 (from leaves) were used for pathogenicity testing of two red-beet cultivars. Isolate PB106 was further used to investigate its effects on spinach and fodder beet as well as red beet under greenhouse conditions. All three P. betae isolates were pathogenic on both red-beet cultivars tested, causing leaf-spot symptoms. Isolates PB101 and PB106 produced significantly larger leaf-spot lesions (P<0.001) compared with PB103. Phoma betae isolate PB106 was pathogenic to both red-beet cultivars, spinach and fodder beet but fodder beet was less susceptible than the other species tested. Regardless of cultivar, <i>P. betae </i>is an important pathogen of beets and is capable of causing leaf spots.
