The arthropod complex associated with Ips typographus (L.) (Coleoptera, Scolytidae): species composition, phenology, and impact on bark beetle productivity. Abstract In spring 1986, arthropods were allowed access to Ips typographus-infested bolts of Picea abies in forest in Uppsala, Sweden, for 0, 1, 4 or 8 weeks. The bolts were then removed from the forested area and placed in screen cages.

Scolytidae definition is - a large family of bark-boring or wood-boring rhynchophorous beetles having a very short beak and clubbed antennae and being small but very destructive to forest trees and fruit trees.

This publication is the second supplement to the 1992 catalogue and updates information from 1995 to the end of 1999. Approximately 7000 species of Scolytidae and 1500 species of Platypodidae occur throughout the world. For workers in forestry and agriculture, the sheer volume of names and literature references represents a formidable obstacle to research.

Beetle eggs generally have smooth surfaces and are soft, though the Cupedidae have hard eggs. Eggs vary widely between species: the eggs tend to be small in species with many instars (larval stages), and in those that lay large numbers of eggs. A female may lay from several dozen to several thousand eggs during her lifetime, depending on the.

A taxonomic revision of the genera of Scolytidae (Coleoptera) in the world fauna is presented. Included are 215 valid genera and 273 invalid generic and subgeneric names. The type-species for each genus-group name was examined, including the type-specimen of the type-species in those taxa where a holotype, lectotype, or neotype has been designated—with the exception of four contemporary.

Hylurgops porosus and H. rugipennis were common to all three sites (), and emerged earlier at Cranbrook and Parson than at Elkford.In general, Dendroctonus species and the Hylurgops species had the earliest mean emergence dates with the exception of the Elkford site where the mean emergence date for the two Hylurgops species was the latest. The difference between the earliest mean emergence.

Subject browse uses CABICODES which are CABI’s own classification codes for broad subjects that would be difficult to describe with keywords alone. Each database record is assigned with at least one CABICODE which describes the relevant area of science. Click on a subject area to search for all records coded with that CABICODE.

All around the second-growth vegetation, the fallen trees and branches rot and crumble offering hiding places and food to a vast array of basidiomycete fungi, slime molds, ponerine ants, scolytid beetles, bark lice, earwigs, embiopteran web spinners, zorapterans, entomobryomorph springtails, japygid diplurans, schizomid arachnids, pseudoscorpions, real scorpions, and other forms that live.

A checklist is given of 109 species of Scolytidae and 25 species of Platypodidae from the island of Penang. The distribution of each species is given, and notes on its biology where possible.
