8. The South And Central African Species Of The Genus Synagris Latreille (Hymenoptera), Joseph Bequaert

Ba

This is the first of a series of articles in which I shall deal with the diplopterous wasps of South and Central Africa, south of 10° S. lat. The area under consideration includes the south-eastern portion of the Belgian Congo, or the Katanga district, which in its fauna and flora has many points in common with Northern Rhodesia, and differs considerably from the equatorial Congo belt. Since for lack of material the wasps of the Katanga could not be fully treated before, the present paper will supplement my Revision of Congo Vespidae (1918).

Enkele Beschouwingen Over Kleuren En Kleurgroepen Bij Plooivleugelige Wespen, (1), Joseph Bequaert

Ba

De kleur der levende wezens is wellicht onder alle eigenschappen deze die het spoedigst de aandacht vestigt. Inderdaad berust het schoonheids-genot dat wij bij het beschouwen van vele dieren en planten smaken, grootendeels op hunne harmonische kleurteekening. Desniettegenstaande is het opmerkelijk dat wij uit een wetenschappelijk oogpunt veel beter over den vorm dan over de kleuren der levende wezens zijn ingelicht. Dit is mijns inziens aan twee hoofdredenen te wijten. Eene eerste moeilijkheid ligt in den aard zelf van het onderwerp. Waarneming in de natuur en experiment in den proeftuin of in het laboratorium hebben al spoedig geleerd hoe de …

Bulletin No. 183 - Water-Holding Capacity Of Irrigated Soils, Orson W. Israelsen, Frank L. West

UAES Bulletins

All information that will 'enable the irrigator to use water economically is valuable to arid-climate agriculture. In many arid-climate regions, including the western part of the United States, excessive waste of water occurs in the irrigation of highland porous soil areas, as a result of lack of information concerning the capacity of the soil to hold water. Following the waste of water on the uplands by excessive percolation through open soils, vast lowland areas are rendered partially or wholly nonproductive by water-logging. To illustrate, a gravelly bench soil four feet deep, if underlain by a coarse open gravel to a …

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 …

Bulletin No. 178 - The Irrigation Of Barley, F. S. Harris, D. W. Pittman

UAES Bulletins

The proper use of irrigation water is one of the most important problems of every comnunity and of every farmer in an irrigated district. The irrigation farmer has largely under his control one of the most important factors in determining the yield and quality of his crops and one over which all other farmers have little control at all. On the other hand, in an arid district there is generally less available irrigation water than is needed to give the optimum amount to all the land, or if one region receives an excess there is generally an accumulation of alkali …

Circular No. 47 - Celery Culture For Utah, T. H. Abell

UAES Circulars

At one time practically all the celery consumed in Utah was shipped from California and eastern states. It was soon discovered, however, that celery could be raised in Utah, and as the population increased more and more acres were utilized in the production of this crop. Very little found its way to the outside markets, but what little did get out was well received because of its very high quality. Men who travel say that "Utah Celery" on the menu on trains and in hotels means the best there is in celery.

Within recent years several carloads have been shipped …

Bulletin No. 181 - Duty-Of-Water Investigations On Coal Creek, Utah, Arthur Fife

UAES Bulletins

Coal Creek flows from the west slope of the part of the Wasatch Mountain range which is located in the southeast part of Iron County, Utah. Its drainage area is almost 100 square miles.

Seasonal and daily stream-flow fluctuations are very pronounced. During the high water of spring the flow has reached more than 600 second-feet. At the time of high water, the daily fluctuations are the greatest. During the low water season in July and August, the flow has dropped as low as 12 second-feet since 1917, when accurate records were first kept; and, from the accounts of early …

Bulletin No. 182 - The Net Duty Of Water In Sevier Valley, Orson W. Israelsen, Luther M. Winsor

UAES Bulletins

The Sevier River is one of the most important sources of irrigation water in Utah. It rises in two main branches. The south fork rises in Kane County and flows almost due north to Junction in Piute County, where it joins the east fork, which rises partly in Garfield County and partly in Sevier County. The Garfield County branch of the east fork flows north, and the Sevier County Branch flows south to Coyote where the two tributaries join and flow westward into Junction. From Junction, the river flows northward past Marysvale, Sevier, Richfield, Salina, Gunnison, and Mills, where it …
