Notes Biologiques Sur Les Mylabres, Auguste Cros

Co

Il y a moins d'un demi-siècle, l'on ignorait encore complètement l'histoire du développement des Mylabres, et leurs formes larvaires étaient totalement inconnues. C'est seulement en 1876 que Valéry MAYET (Sur les triongulins des Mylabres, Ann. Soc. ent. Fr. [1876], Bull., p. 196) donna les premières indications sur ce sujet et décrivit sommairement la larve primaire d'un de ces insectes, le Zonabris quadripunctata L., mais sa découverte passa à peu près inaperçue.

A Synopsis Of The Sphecoidea Of Nebraska (Hymenoptera), Clarence E. Mickel Oct 1917

A Synopsis Of The Sphecoidea Of Nebraska (Hymenoptera), Clarence E. Mickel

University Studies (University of Nebraska) (1888–1984)

The following paper is the result of three years more or less intermittent study and collecting of the entomophilous wasps of the superfamily Sphecoidea. In 1908, Mr. H. S. Smith published a list of Nebraska Sphecoidea together with synoptic tables, descriptions of new species and notes. The University of N ebraska collection of this group has more than doubled in size since 1908, the collection of Nebraska specimens now numbering about 7,000, while the entire collection of Sphecoidea includes between 8,000 and 9,000 specimens. This wealth of material has naturally increased the number of species known to occur within the …

The Production Of Alfalfa Seed In Southern Idaho, L. C. Aicher Jul 1917

The Production Of Alfalfa Seed In Southern Idaho, L. C. Aicher

A

The acreage given over to the production of alfalfa seed is rapidly increasing in Idaho because of the widespread interest throughout the east in growing alfalfa as a forage crop, the growing demand of eastern farmers for high-grade seed, and the higher prices obtainable since the beginning of the world war. In growing alfalfa farmers have discovered thru experience and heavy losses at times that it is more profitable to plant high-grade than inferior seed. In response to the demands of their customers and because of stringent weed laws of some states, seedsman are becoming more and more particular in …

Color And Color-Pattern Mechanism Of Tiger Beetles, Victor E. Shelford Jun 1917

Color And Color-Pattern Mechanism Of Tiger Beetles, Victor E. Shelford

University of Nebraska State Museum: Entomology Papers

In 1903 the writer undertook a study of variation of the tiger beetles. The work here presented is the outgrowth of this beginning, and indeed includes some small portions regarding color patterns that were written in that year. The work has been prolonged for many reasons, but chief of these was the very large number of species in the group and the fact that an adequate understanding of the material could not be attained without consulting many large collections. Further, the experimental results obtained in 1906 demanded a firsthand study of the variations of the species concerned and their natural …

The more important questions which were considered during the three years covered by the present report were as follows: 1. How many summer sprays are required and when should they be applied? 2. What is the difference in efficiency between various brands of arsenate of lead? 3. What are the relative values of lime sulphur and Bordeaux as fungicides for spraying apples? 4. Is it possible to lessen or prevent Bordeaux injury and at the same time control fungous diseases? 5. Is it possible to interchange Bordeaux and lime sulphur in a spray schedule in such a manner as to …
