Sound production in Scolytidae: Attraction and stridulation of Scolytus mali (Col., Scolytidae)
Zeitschrift für Angewandte Entomologie, 1978AbstractScolytus maliwas found to have brief maturation feeding on living but weakened apple trees. After five‐day feeding, the oocytes matured and most of the beetles left and aggregated for breeding in response to a female‐produced pheromone. Although mating was observed only at the maturation feeding site, males were present in the breeding ...

BARK BEETLE (SCOLYTIDAE) IN CROATIAN ORCHARDS
Acta Horticulturae, 2000According to data in the literature, the bark beetle appears mainly on weakened fruit trees of different scion varieties. Thus, stronger populations may be found on trees damaged by low temperatures, drought, rodents, or diseases of the roots or crown. Only in exceptional circumstances, with the appearance of a strong bark beetle population, were they ...

The Scolytidae and Platypodidae (Coleoptera) of Thailand
Oriental Insects, 1975Abstract A checklist is given of 70 speciese of Scolytidae and 26 species of Platypodidae from Thailand. The distribution of each species is given, and notes on its biology where possible. The species are classified into six faunal elements: Palearctic (4 species), Indian (18 species), Malaysian (23 species), Indo-malaysian (22 species), Circumtropical

THE IMMATURE STAGES OF SCOLYTIDAE: THE GENUS CONOPHTHORUS (COLEOPTERA: SCOLYTIDAE)
The Canadian Entomologist, 1971AbstractAn anatomical description of the larval and pupal stages of the genus Conophthorus Hopkins is given and illustrated. The description is based on larvae of nine species and pupae of eight, but the strong similarity in all anatomical details suggests that the description will probably cover the remaining species.

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.

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.
