Bulletin No. 110 - The Alfalfa Leaf-Weevil, E. G. Titus

UAES Bulletins

The alfalfa leaf-weevil (Phytonomus murinus Fab.) which has during the last three years been doing considerable damage in the central part of this State, is a European insect which by some means unknown has been introduced in to Utah. The species appears to be not uncommon throughout Europe and parts of Asia and Africa. It belongs to the large order of hard-shelled insects called beetles (Coleoptera) and in a group generally called snout-beetles (Family Curculionidae). To this same group belong many of our most serious pests, such as the plum curculio, cotton boll-weevil and strawberry weevil.

Bulletin No. 108 - The Effect Of Formalin On The Vitality Of Seed Grain, Robert Stewart, John Stephens

UAES Bulletins

The Utah Experiment Station for a number of years has recommended the formalin treatment for the prevention of smut in wheat, oats and barley. Since the publication of Bulletin No. 84 by Prof. L. A. Merrill on the Subject, a number of complaints regarding the treatment have been received. We learned, also, by traveling over the state, that these complaints were quite general. The work reported in this bulletin was undertaken for the purpose of throwing light on these questions, and it is hoped that the results obtained will be of value to the farmers of the state.

Beitrag Zur Kenntnis Der Mit Tetralonia Verwandten Bienen Aus Sudamerika., A. W. Bertoni, C. Schrottky

Ba

Unter dem Sammelnamen TetraZonia sind in den letzten Jahren eine Menge neuer Arten aus Südamerika beschrieben worden, ohne daß deren Verwandtschaft angegeben wäre, oder aber, wo die neuen Arten auf verschiedene Gattungen verteilt wurden, ist dies einzig auf die Zahl der Palpenglieder hin erfolgt, ein Verfahren, das niemals gebilligt werden kann, weil eine auf nur ein Organ begründete Einteilung notwendigerweise mangelhaft sein muß. Es ist daher wohl zu entschuldigen , wenn mehrere Bearbeiter den in dieser Gruppe aufgestellten neuen Gattungen überhaupt keine Beachtung schenkten. Indessen sind die Schwierigkeiten, sich in der wachsenden Zahl der „Tetralonia"-Arten zurechtzufinden, immer größer geworden, so …
