Abstract A description is provided for Guignardia aesculi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Aesculus glabra, A. hippocastanum (main host) (Hippocastanaceae). Several other species of Aesculus and subspecies including A. ambigua, A. arnoldiana, A. bushii, A. carnea, A. discolor, A. dupontii, A. hybrida, A. mississippiensis, A. mutabilis, A. neglecta, A. octandra, A. pavia, A. splendens, A. turbinata and A. woerlitzensis have been reported to be susceptible (Neely & Himelick, 1963; 50, 2509). DISEASE: Leaf blotch or black rot of Aesculus hippocastanum (horse chestnut) and other Aesculus species (5, 706; 28, 38; 64, 4521). GEOGRAPHICAL DISTRIBUTION: Europe (Austria, Belgium, France, Germany, Italy, Netherlands, Portugal, Romania, Switzerland, U.K., Yugoslavia); North America (Canada: Manitoba, New Brunswick, Nova Scotia, Ontario, Quebec; U.S.A. : Eastern U.S.A). TRANSMISSION: Presumably by water-borne conidia during wet conditions. Ascomata are produced on leaves left to over winter outside and both conidia and ascospores discharged from over wintered leaves have been reported to infect leaves of seedlings and produce blotch symptoms (Hudson, 1987).

AbstractThe number of predators inhabiting nests of Hyphantria cunea Drury was recorded annually for 13 years in four areas in New Brunswick and two areas on the coast of Nova Scotia. The most common groups were the pentatomids and spiders, which sometimes reproduced within the nests, but the mean number per nest was low in relation to the number of H. cunea larvae in the colonies. The rate of predation on fifth-instar larvae was low. Small or timid predators appeared to prey largely on moribund larvae or small saprophagans during the principal defoliating instars of H. cunea.No relationship could be detected between the number of larvae reaching the fifth instar and the number of predators in the colony; nor could any functional or numerical response of the predators to either the initial number of larvae per colony or the population density of colonies be found. It is concluded that the influence of the nest-inhabiting predators is small and relatively stable, and may be treated as a constant in the development of models to explain the population dynamics of H. cunea.H. cunea is a pest in parts of Europe and Asia, where it has been accidentally introduced from North America. The introduction to other continents of the North American predator, Podisus maculiventiis (Say), is discussed briefly.
