Insect Pests Of Stored Grains And Their Control, M. H. Swenk Dec 1922

Insect Pests Of Stored Grains And Their Control, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Circulars

In Nebraska there are about 20 species of insects that injure stored grain more or less. Some are beetles and their larvae, others are the caterpillars of small moths. To the farmer all are "weevil," although that name is really properly applied only to two beetle species-the granary weevil and the rice weevil. The following paragraphs and illustrations will describe the several more important stored grain pests to be found in this State, so that the farmer may recognize the particular pest or pests that are doing the injury to his grain, and may then apply the proper remedy.

Iii. The Predaceous Enemies Of Ants, Joseph Bequaert

Ba

The various means by which Nature prevents an excessive increase of the species not only forms in itself an interesting chapter of ecology, but its study is also of great importance in an understanding of the true meaning of Natural Selection. In the case of ants it has been contended that they are better defended than other insects against the attacks of predatory animals. Poulton evidently takes this for granted when he considers that ants, together with wasps, are among the favorite models for "mimicking" insects and other arthropods. These ant-like arthropods, having acquired by Natural Selection their resemblance "to …

A Synopsis Of The Scarabaeidae Of Nebraska (Coleoptera), R. W. Dawson Jul 1922

A Synopsis Of The Scarabaeidae Of Nebraska (Coleoptera), R. W. Dawson

Papers from the University Studies series (University of Nebraska)

Several years ago the writer undertook a study of the "June-bug" family (Scarabaeidae) for the state of Nebraska. The object of the study was two fold: First to determine the number and status of our species in this large and economically important family, and second to present a taxonomic review which would enable the beginning student, or interested amateur, to readily name with reasonable certainty any species which he might encounter in the state.

In the following pages 40 genera and 162 species are tabulated, and notes given on the abundance, seasonal and geographical distribution of the species within the …


A Synopsis Of The Syrphidae Of Nebraska With Descriptions Of New Species From Nebraska And Colorado, Everett E. Wehr Jul 1922

A Synopsis Of The Syrphidae Of Nebraska With Descriptions Of New Species From Nebraska And Colorado, Everett E. Wehr

Papers from the University Studies series (University of Nebraska)

In June, 1907, Mr. Paul R. Jones published in the Journal of the New York Entomological Society "A Preliminary List of Nebraska Syrphidae with Descriptions of New Species.'" At that time there was available only a comparatively small collection of Syrphid flies, but apparently it contained a fairly good representation of the species found in the state. Subsequent collectors have contributed a considerable amount of new material from the state in which there are twelve additional species, two of which are· new. With these additions, the Nebraska list is increased to ninety species.

At the present time the classification of …

Von Herrn Prof. R Ebner in Wien erhielt ich eine Sammlung von Bienen zur Bearbeitung, die der genannte Forscher als Entomologe der zoologischen Expedition Prof. Dr. F. Werners von Februar bis April 1914 in Agypten und im agyptischen Sudan groBltenteils selbst sammelte. Da die Sammlung eine Reihe neuer und wenig bekannter Arten und sogar eine neue Gattung enthalt, und da ein Teil der Arten von Orten stammt, wo das palaearktische und athiopische Faunengebiet zusammenstoBen, durfte eine Veroffentlichung der Sammelergebnisse angebracht sein. In der Anordnung der Gattungen und Familien folge ich dem von meinem Freunde C. Borner in seiner Arbeit »Stammesgeschichte …
