Observations On Two Stem-Boring Coleoptera Of Prickly-Ash (Zanthoxylum Americanum) In Michigan: Micracis Suturalis (Curculionidae: Scolytinae) And Sternidius Alpha (Cerambycidae), Robert A. Haack
The Great Lakes Entomologist
The xylophagous scolytine Micracis suturalis LeConte and the cerambycid beetle Sternidius alpha (Say) were reared or collected from trunk sections of prickly-ash, Zanthoxylum americanum Mill., in Ingham County, Michigan during 1986 to 1988. Most M. suturalis gallery systems were initiated by August in host material cut in late May 1987. Micracis suturalis gallery-system density data are presented. No M. suturalis were reared from caged host material one-year after cutting. Sternidius alpha was univoltine, with adults emerging from mid-May to mid-July from host material cut the previous spring. From 1 to 8 S. alpha larvae originated from individual oviposition sites, averaging …
Bark- And Wood-Infesting Insects (Coleoptera And Hymenoptera) And Associated Parasitoids Reared From Yellow Birch (Betula Alleghaniensis) In Ingham County, Michigan, Robert A. Haack
The Great Lakes Entomologist
Four species of bark- and wood-infesting borers (two Coleoptera and two Hymenoptera) and six parasitoid species (Hymenoptera) were reared from yellow birch (Betula alleghaniensis Britton) one year after the trees were cut and left standing in a woodlot in Ingham County, Michigan in 1986–87. The borers were species of Cerambycidae (Coleoptera) and Xiphydriidae (Hymenoptera), and hymenopteran parasitoid species of Aulacidae, Braconidae, Chalcididae, and Pteromalidae. Xiphydriophagus meyerinckii (Ratzeburg) (Pteromalidae) is a new Michigan state record. For the borers, yellow birch is a new host record for the cerambycid Sternidius alpha (Say) and the xiphydriid Xiphydria tibialis Say. Seasonal emergence data …
Bark- And Wood-Infesting Coleoptera And Associated Parasitoids Reared From Shagbark Hickory (Carya Ovata) And Slippery Elm (Ulmus Rubra) In Ingham County, Michigan, Robert A. Haack
The Great Lakes Entomologist
Ten species of bark- and wood-infesting Coleoptera (borers) and five parasitoid species (Hymenoptera) were reared from shagbark hickory (Carya ovata) branches 1-2 years after tree death, and similarly, seven borers and eight parasitoids were reared from slippery elm (Ulmus rubra) branches one year after tree death in Ingham County, Michigan, in 1986-87. The borers were species of bostrichids, buprestids, cerambycids, and curculionids (including Scolytinae). The parasitoids were braconids, chalcidids, eurytomids, ichneumonids, and pteromalids. One new larval host record was recorded: the cerambycid Urgleptes querci (Fitch), being reared from U. rubra. This paper presents new Michigan …
