AbstractThis study deals with the larval morphology of the six commonest species of Chrysobothris that occur in eastern Canada. The morphology of the genus is presented as a guide to the terminology. For each species, a short diagnosis is given, followed by a detailed description, its geographical distribution and a list of its host-plant genera. A key to the larvae is provided.

Abstract A description is provided for Podosphaera clandestina. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Crataegus monogyna, C. pentagyna, C. punctata, Mespilus germanica, Cratoegomespilus grandiflora, C. dardari, Pyrus communis, Cydonia vulgaris, Pyrocydonia winkleri and P. danieli. DISEASE: Hawthorn mildew. Severe attacks cause defoliation and death of terminal buds on young seedlings and on soft shoots on hedges and trees. The disease has been recorded on hawthorn fruits. The host plant can be grown only from seeds. GEOGRAPHICAL DISTRIBUTION: Worldwide (Salmon, 1900; 45, 3081). Cleistothecia play no part in the disease in England. The overwintering mycelium, inside infected buds, survives until the following spring. These infected buds are the primary infections found each year. Secondary infection is by air-borne conidia.

Abstract A description is provided for Puccinia levis var. brachiariae comb. nov., which causes small lesions on young stems and leaf lamina of the host plant and, where present in quantity, could significantly reduce vigour. Some information on its dispersal and transmission and conservation status is given, along with details of its geographical distribution (Malawi, Uganda, Zambia and Brazil) and hosts (Brachiaria brizantha [Urochloa brizantha], B. decumbens [Urochloa decumbens], B. humidicola [Urochloa humidicola] and an unnamed Brachiaria sp.).

Recent exploration on the mountains of Northern Mindanao, Philippines resulted in the recollection of Etlingera pubimarginata, an enigmatic endemic species recollected after a lapse of over a century. An amended taxonomic description with colour photographs as well as comparative morphology to its allied species, geographical distribution, and conservation status are provided.

Documentation of the early immature stages (egg, larva, chrysalis) of the White Four-ring (Ypthima ceylonica Hewitson, 1865), including larval morphology and behaviour, is described for the first time from India.  A new host plant (Cynodon dactylon (L.) Pers.) is also reported for this butterfly.

Comparative analysis of Dendrocometes paradoxus Stein, 1852 cell morphology from various gammarid amphipod species in different regions of Ukraine, and those attached to several host body parts of Hyalella azteca collected in two Mexican lakes, was carried out in order to demonstrate the morphological variability, due to the hosts species or their geographical distribution. For hosts species and corporal distribution, no significant differences between the two populations were shown. As the result, it was found the suctorians common for amphipod crustaceans from Ukraine and Mexico all are conspecific and belong to D. paradoxus.

Abstract A description is provided for Ceratocystis ulmi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Ulmus spp., Zelkova serrara; U. glabra and U. americana are highly susceptible, U. procera is susceptible, while Asian elms, U. parvifolia, U. pumila and U. pumila pennato-ramosa, have marked resistance. Zelkova serrata is highly susceptible; the reactions of other species of Zelkova are not known. DISEASE: Dutch Elm Disease. GEOGRAPHICAL DISTRIBUTION: Europe (throughout, to a northern limit in central Scotland, central Norway, central Sweden. Absent from north Russia). N. America (eastern Canada, central and eastern USA) (CMI Map 36, ed. 4, 1970). TRANSMISSION: By the bark beetles Scolytus scolytus, S. multistriatus and (in N. America) by Hylurgopinus rufipes. The fungus fruits in the larval galleries and spores are carried internally and externally to young shoots where beetles emerge and migrate. Infection of the vessels, which leads to the disease, takes place during the period before breeding, when the beetles feed, cutting grooves and boring in the thin bark of twigs. Transmission by root grafts is known (15, 266) and direct infection by airborne spores is theoretically possible but does not take place under natural conditions.

Abstract A description is provided for Thecaphora lathyri, found in dead fruits of the host plant (Lathyrus pratensis), infecting and destroying the seeds, the spore mass granular, dark chestnut brown, ± completely filling the fruit cavity; host fruits somewhat swollen in external view, but otherwise not visibly affected. Some information on its associated organisms and substrata, dispersal and transmission, habitats and conservation status is given, along with details of its geographical distribution (North America (USA (Utah)), Asia (Kazakhstan (East Kazakhstan), Russia (Altai)), Europe (Finland, Germany, Italy, Switzerland, UK)).

Abstract A description is provided for Corollospora pseudopulchella. Information on the host plant (Thalassia testudinum), geographical distribution (Mexico, Japan, Thailand, Cuba, Dominican Republic, Puerto Rico and Denmark), and dispersal and transmission of the pathogen is presented.
