Evidence Of Lilac Borer (Lepidoptera: Sesiidae) Population On Mackinac Island, Mi, David Max Lowenstein

The Great Lakes Entomologist

Mackinac Island, Michigan, is a major tourism destination with its lilacs an important part of the local culture. Recently, the health of some lilacs has declined. It is uncertain if this is due to the lilac’s age, attack by lilac borer, Podosesia syringae (Harris) (Lepidoptera: Sesiidae), or a combination of environmental and biotic factors. The lilac borer is a clearwing moth whose larvae bore within ash and lilac, and there are minimal local records of the insect in Northern Michigan and none on Mackinac Island. This study deployed pheromone traps to identify the flight period of lilac borer, potential damage …

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 …

Buprestidae, Cerambycidae, And Siricidae Collected In Baited Funnel Traps On Drummond Island, Chippewa County, Michigan, Robert Haack

The Great Lakes Entomologist

Trapping of bark- and wood-infesting insects in 2015 and 2016 at multiple locations on Drummond Island in northern Lake Huron, using baited multi-funnel traps, yielded 4 species of Buprestidae, 24 Cerambycidae, and 4 Siricidae. In 2015, all funnel traps were baited with the plant volatiles α-pinene, ethanol, and cis-3-hexenol, and were either black or green in color, and placed either at heights similar to the lower canopy of nearby trees (4-5 m) or at 1-2 m above groundline. In 2016, all traps were green, hung at 1-2 m above groundline, and baited with the cerambycid pheromones fuscumol acetate, monochamol, and …

G94-1210 Borers Of Shade Trees And Ornamental Plants, Frederick P. Baxendale, David L. Keith, J. Ackland Jones

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes the important shade tree and ornamental borers in Nebraska and discusses their management.

Nearly all shade trees are subject to borer attack. If damage is severe, young trees are likely to decline or die.

Marketing Of Aspen, Zigmond A. Zasada

Aspen Bibliography

The Lake States timber industry did a creditable job of producing and using considerable volumes of aspen during the war years. At that time it was shown that aspen could fill a variety of uses satisfactorily. However, improved marketing techniques are needed if present aspen stands are to be fully and profitably utilized. The aim of this paper is to call the attention of owners and producers of aspen to some of the points to be considered to improve marketing.

Spraying Tree Fruits, C. C. Wiggans, E. H. Hoppert

Nebraska Agricultural Experiment Station: Historical Circulars

The production of sound, clean fruit is unquestionably one of the major problems facing the modern fruit grower. Culture may be neglected and pruning delayed for a time but the omission of sprays for even a single season demonstrates their absolute necessity. This applies equally to the commercial grower and to the farmer or gardener who has only a few trees.

Ec28-36 Spraying Tree Fruits (Revised March 1932), C.C. Wiggans, E.H. Hoppert

University of Nebraska-Lincoln Extension: Historical Materials

The production of sound, clean fruit is unquestionably one of the major problems facing the modern fruit grower. Culture may be neglected and pruning delayed for a time but the omission of sprays for even a single season demonstrates their absolute necessity. This applies equally to the commercial grower and to the farmer or gardener who has only a few trees.

Spray materials, equipment, management, schedules, insect pests and orchard diseases are discussed in this 1928 extension circular.
