Abundance And Diversity

We summarize the effects of major weather events such as ice storms, wind storms, and flooding on the abundance and diversity of terrestrial forest insects and their allies. This synthesis indicates that weather events influence both spatial and temporal patterns of forests and insect communities in North American landscapes. The Atlantic and Pacific oceanic sides of the continent are relatively more susceptible to ice and wind storms, respectively. There have been more studies and reports on the responses of forest insects to wind storms, and on economically important subcortical insects than on gall-forming, foliage-feeding, fungal-feeding, litter-dwelling, pollinating, parasitizing, predaceous, root-feeding, and sap-feeding insects. Weather events positively affect populations of subcortical insect species, and impact their colonization patterns and dynamics. Species belonging to genera such as Dendroctonus (Scolytidae) and Monochamus (Cerambycidae) may sometimes cause economic damage by colonizing residual live tree, and dead trees, rendering the wood unsalvageable. Subsequent outbreaks of spruce beetle, Dendroctonus rufipennis (Kirby) and Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, have been frequently documented in western North American forests following wind events. Wind disturbances have also been observed to accelerate the life-cycles of D. rufipennis and Semanotus litigiosus (Casey) (Cerambycidae), and in rare instances, have caused Monochamus spp. to become primary colonizers. Populations of other important subcortical species have not always increased dramatically following weather events. Foliage- and pollen-feeding insects may experience mortality directly from a weather event or indirectly through habitat alteration. In some cases, forest insects may use storms to migrate to new habitats. Populations of open-habitat and forest specialist litter-dwelling species have increased and decreased, respectively, subsequent to weather events. Forest specialist species generally rebound within a short period of time, suggesting that they are adapted to these periodic weather events. Little is known about the combined effects of post-weather-disturbance management practices such as salvage-logging and prescribed-burning on insects in North American forests.

The Family

The first part of the work consists of an annotated list of the insects affecting the trees. The host trees are mentioned by their scientific names in alpahabetical order, and the insects are listed under each species of tree. Directly under the name of each tree, the family to which it belongs is cited, followed by notes on distribution, uses or economic importance and common names of the tree species. Then the insects are listed or recorded, following more or less this sequence: insects affecting the flowers, fruits or seeds, twigs, branches, trunk and roots. Often, species attacking the decayed wood or resting on the tree will be mentioned at the end of each 565 tree discussed. Only the insects affecting the trees are recorded, that is, such records as "on the leaves", or "collected on the fruit", "on the trunk", etc., are not taken in consideration in this work. The parasitic forms are only mentioned when the specific host is known, otherwise parasites and predators just resting on leaves or other parts of the trees are not listed. This Survey is based on the insect population studies on 245 tree species, belonging to 169 genera. In the annotated list some trees only show two or three insects records while others might show thirty, forty or more records.

One New Species

AbstractOnly one species of Anoetidae was previously recorded associated with North American Scolytidae. Five new species of Anoetus and one new species of Bonomoia associated with North American bark beetles are described. Two nomen novum (due to homonymy) in the genus Anoetus are proposed. Anoetus varia is distinguished from A. gordius, a European species restricted to Ips laricis. Anoetus varia is recorded from 17 scolytids infesting 10 conifer species from 14 states and provinces. An annotated list, with new nomenclatorial combinations in many cases, of the 13 anoetids recorded associated with scolytids in the old world is given. Histiostoma is synonymized under Anoetus.

Red Wood Ant

AbstractThe important species of predacious ants in Europe and North America belonging to the Formica rufa L. group, and their association with forest insects, is discussed. The absence of desirable species in Quebec is stated, and a brief description of an aggressive western North American species (F. obscuripes Forel) is given. The method used in collecting large colonies of this species in Manitoba, of transportation to Quebec, and of the eventual release and establishment is described. It is concluded that F. obscuripes is increasing in number in Quebec, and should be considered as permanently established.
