The native resident fauna of these islands consists of 42 species of which 21 (50%) are endemic, in 27 genera, of which 3 (11%) are endemic, in 12 families. The endemic fauna is characterised by brachyptery (66%), body size under 10 mm (72%) and concealed, or strictly ground- dwelling larval life. All species can be related to mainland forms; there is a distinctive pre-Pleistocene element as well as some instances of possible Pleistocene introductions, as suggested by the presence of pairs of species, one member of which is endemic but fully winged. A graph and tables are given showing the composition of the fauna, its distribution, habits, and presumed derivations. Host plants or host niches are discussed. An additional 7 species are considered to be non-resident waifs. The taxonomic part includes keys to families (applicable only to the subantarctic fauna), and to genera and species.

The pear-slug, or cherry-slug, is a dark, almost black, slimy slug, about 2-5 of an inch long when full grown, which feeds on cherry, pear and plum leaves. 2. These slugs feed on the upper sides of the leaves, eating out all the tissue except the veins and the lower surface. The injured leaves become dry and brown and fall from the trees, which are sometimes left entirely bare of foliage in midsummer. 3. Trees are often killed as a result of repeated defoliation. A short crop of fruit follows a severe attack by this insect, on ac­ count of the weakened condition of the tree.

  • Backyard Pest Management: Pests of Small Fruit

    Backyard Pest Management: Pests of Small Fruit

    Pests of Small Fruits – 1 – Introduction Managing common insects, weeds, plant diseases and certain animal pests found in the backyard can be a challenge. However, there are a number of ways to approach the problem. Information in this publication will help identify and manage pest problems. Pest management methods will vary among individuals according to their tolerance of the pest, the damage and a basic philosophy about handling pest problems. It may not be necessary to control pests if numbers are low and damage is not significant.At other times, simply spraying a tree with water, pruning a branch or digging up a weed will reduce or eliminate the problem. Natural predators may also control the pest problem. Backyard Pest Management is designed to help focus on the key areas of pest management. The first section provides basic approaches to pest management and looks at ways to prevent problems and handle them as they arise. Further sections focus focus on the insects and the types of plants they damage. There are many ways to deal with backyard pest problems. When using pesticides to control a problem, there is the potential for damage and the possibility of legal issues. Use pesticides with caution and always according to label directions. Approaches to Pest Management Integrated Pest Management (IPM) is an environmentally responsible approach to pest management. IPM focuses on prevention, and if problems occur, the method provides a variety of control strategies. Prevention Prevention is the foundation of an IPM program, and one way to do prevent problems is to choose the right plant for a specific location and provide the best growing conditions.
  • The Current Currant “Worm”

    The Current Currant “Worm”

    The Current Currant “Worm” By Virgene Link-New July 3, 2020 Damaging predators take advantage of warmer weather We are eager in spring to see buds opening and flowers blooming after a dark, mostly rainy winter. Sometimes in spring when we venture out on a nicer day we are met with the surprise of our currant leaves being reduced to veins, a mere skeleton of themselves. The imported currantworm (Nematus ribesii) is a sawfly larva that feeds on and skeletonizes currant and gooseberry leaves. It is neither a “saw” nor a “fly,” but a member of the order Hymenoptera (ants, bees and wasps). The adult wasp has a thick, broadly joined waist and looks very much like a fly, but with two pair of wings. Flies (Diptera) have one pair of wings. The female has a saw-like ovipositor (a tubular organ through which a female insect deposits eggs), hence the name “sawfly.” She uses this to insert eggs into plant tissue, usually along the veins beneath the leaf. It does NOT have a stinger. We rarely notice the adult of this species as it is small, about one-third inch in length and is black and yellow. Adults are usually found on flowers. The larvae look like a butterfly or moth caterpillars with a recognizable “head” and soft body, but there are noticeable differences to the specialist. The larvae emerge from the newly opened currant leaves. They grow rapidly and can completely defoliate the plant almost overnight if action is not taken. Larvae are whitish at first and then become green with black spots as they mature to about one-half inch.
