A New Species Of Mnioes (Hymenoptera: Ichneumonidae) From The United States, Patrick C. Kennedy Apr 2017

A New Species Of Mnioes (Hymenoptera: Ichneumonidae) From The United States, Patrick C. Kennedy

The Great Lakes Entomologist

This is the first record of the genus Mnioes in the United States. Previously described species are all Neotropic. Townes described the genus in 1946, placing Lampronota? jircunda Cresson, 1874, and Meniscus ? orbitalis Cresson, 1874, in it. The new species described here has been collected from several areas in the United States. This study was made while the author was a graduate student at The University of Michigan, Ann Arbor, Michigan.


Relationships Between The Mandibles, Feeding Behavior, And Damage Inflicted On Plants By The Feeding Of Certain Acridids (Orthoptera), S. K. Gangwere Apr 2017

Relationships Between The Mandibles, Feeding Behavior, And Damage Inflicted On Plants By The Feeding Of Certain Acridids (Orthoptera), S. K. Gangwere

The Great Lakes Entomologist

[excerpt] In 1960 the author described three fundamental patterns of feed- ing in Orthoptera and their allies and emphasized the close correlation that exists between the insects' mouthpart structure, food, and feeding pattern. An article by Anderson (1964) made reference to these described patterns and discussed possible modifications of them. To the author's knowledge these are the only reports available that make other than casual mention of the characteristic damage by Orthoptera to food plants. Numerous other papers include figures that depict orthopteran damage, and still others verbally describe the damage inflicted by various economically important species. In all these …


Interference Of The Snail Physa Sayii With Equilibrium In Tropisternus Glaber (Coleoptera: Hydrophilidae), Ronald B. Willson Apr 2017

Interference Of The Snail Physa Sayii With Equilibrium In Tropisternus Glaber (Coleoptera: Hydrophilidae), Ronald B. Willson

The Great Lakes Entomologist

[excerpt] On January 9, 1964, a larva of the hydrophilid beetle Tropister- nus,glaber (Herbst) was removed from an aquarium and placed in a fin- ger bowl of water along with a sprig of coontail (Ceratop7tyllum demer- sum Linnaeus). The plant provided support for the larva to reach the water's surface. By accident rather than design it harbored the snail Physa sayii (Tappan), individuals of which were clinging to its leaves


The Invention Of "Sugaring" For Moths In Ninetheeth-Century England, Ronald Sterne Wilkinson Apr 2017

The Invention Of "Sugaring" For Moths In Ninetheeth-Century England, Ronald Sterne Wilkinson

The Great Lakes Entomologist

[excerpt] Those who find enjoyment in the books of P. B.M. Allan have had at least an introduction to the history of our familiar method of using artificial bait to attract nocturnal Lepidoptera (Allan, 1937, 1943, 1947). While the present paper was in manuscript, D. E. Allen's welcome contribution on the origin of the method came to hand (Allen, 1965); several historians of science have since added their comments (Allan, 1965; Wilkinson, 1965). The discovery of additional material in the publications of the early nineteenth century has made desirable a summary of what we now know about the development of …
