The Scolytidae and Platypodidae (Coleoptera) of Penang, Malaysia
Oriental Insects, 1978Abstract 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. Numerous new host records are included. The species are classified into six faunal elements : Eastern Palaearctic (1 species), Indian (3 species ...

Some oriental Scolytidae and Platypodidae (Coleoptera)
Oriental Insects, 1972The following notes and descriptions of previously unknown species are based on several collections that have recently come to me for identification. Some of the records from Thailand are of particular interest, illustrating the wide range of the Scolytid fauna that exists in this country; they include elements of the Malaysian, the Himalayan and the ...

Research on Parasitoids and Predators of Scolytidae – A Review
2007Scolytidae are major forest pests in Europe. For example, Ips typographus (L.) is considered the main pest problem in forestry in many central and northern European countries. Consequently, there is a long tradition of forest entomology studying various aspects of bark beetle ecology, including their natural enemy complexes, with a view to developing ...

Environmental Entomology, 1983
From 1979 to 1981, the number of ponderosa pines attacked by Dendroctonus valens LeConte was monitored in conjunction with a series of experiments on Dendroctonus brevicomis LeConte. During these experiments, over 100 trees were baited with D. brevicomis pheromone.

Elm bark beetles are widely spread in oak stands of Kharkiv region, where they colonize weakened and drying trees. They form dense populations in logs and wood debris, which brings to their accumulation in the stands. Scolytus multistriatus Marsh., S. pygmaeus F., S. pygmaeus F. and Pteleobius vittatus F. are the dominants.

Biology of Dendroctonus punctatus (Coleoptera: Scolytidae)
Annals of the Entomological Society of America, 1995The biology of Dendroctonus punctatus LeConte was studied in white spruce, Picea glauca (Moench) Voss, forests of boreal western North America and in the laboratory. Engelmann spruce, P. engelmannii (Parry) Engelmann, was not found to be infested in nature but was used successfully for rearing in the laboratory.

The Immature Stages of Scolytidae: The Tribe Xyloterini
The Canadian Entomologist, 1960Larval anatomy as an aid to understanding taxonomic and phylogenetic relationships of Scolytidae has been discussed in an earlier paper (Thomas, 1957). Before an appreciation of relationships can be gained, however, comparative descriptions of many species must be compiled.

THREE NEW SPECIES OF SCOLYTIDAE (COLEOPTERA)
The Canadian Entomologist, 1934Length 2.5 mm., width 1.1 mm. Pronotum and elytra equal in width, sides straight and parallel, elytra arcuately narrowed on the caudal third, very broadly obtuse behind; dark reddish brown; pubescence sparse, erect and yellow, more evident about the apex of the pronotum and on the elytral declivity.The head has the frons broadly, feebly convex, the ...

A NEW SPECIES OF IPS (COLEOPTERA, SCOLYTIDAE)
The Canadian Entomologist, 1939The small group of the genus Ips placed at the end of Dr. Swaine's key seems to have a character not found elsewhere in the genus. The epistomal region, in the males, is elevated and often has a dense brush of hairs which make the elevation look greater than it really is. However, this brush is often rubbed until it has entirely disappeared.
