Influence Of Logging On Douglas Fir Beetle Populations, R R. Lejeune, L H. Mcmullen, M D. Atkins

The Bark Beetles, Fuels, and Fire Bibliography

All species of bark beetles of economic importance prefer to attack freshly-killed host material. Logging slash, wind-throw, and fire-killed timber provide ideal breeding grounds for bark beetles. A few species, mostly in the Dendroctonus group, are able to kill living trees. When beetles in the group, raised in preferred host material, cannot find any or enough freshly-killed trees, logs, or slash to enter, they may attack living trees. In the interior of British Columbia, infestations of the Douglas fir beetle can often be traced to logging disturbance.

Winter Pests In The Pasture, P N. Forte

Journal of the Department of Agriculture, Western Australia, Series 4

ALTHOUGH the pests concerned in attacking winter pastures are known to most farmers a discussion of their control and relative importance will not be out of place.

The principal pests concerned fall into two groups. Firstly the red-legged earth mite and lucerne flea whose attacks are most noticeable soon after germination and secondly a group of caterpillars which appear about the same time and whose attack is not noticed until a large amount of damage has been done.

National Parks Of Western Australia, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

NATIONAL PARKS," says the Encyclopaedia Britannica, "are spacious land areas, essentially of primitive or wilderness character, that contain scenery and natural wonder so outstanding in quality that their preservation intact for the benefit, enjoyment and inspiration of the people, is a national concern."

New Recommendations For Fruit Fly Control, D G. Shedley

Journal of the Department of Agriculture, Western Australia, Series 4

THE MEDITERRANEAN FRUIT FLY (Ceratitis capitata Wied) is one of the most serious horticultural pests in Western Australia.

For more than 50 years growers of stone fruit and pears have not been able to relax their activities against this pest.

Despite all their action however, there have been many occasions when fruit losses have been very severe.

Letter From Lawrence W. Quate To Dr. Jane C. Dirks-Edmunds, Lawrence W. Quate

Jane Claire Dirks-Edmunds Documents

This letter from Dr. Lawrence W. Quate is one of many such letters received by Dr. Jane Claire Dirks-Edmunds. Dirks-Edmunds consulted a number of experts to help identify the specimens she collected while conducting fieldwork. Quate was an expert on midges, also known as psychodids. Many of the colleagues with whom Dirks-Edmunds corresponded resided far afield from her research site on Saddleback Mountain in Oregon.

Dirks-Edmunds, a 1937 graduate of Linfield College, graduated from the University of Illinois in 1941; she returned to teach in the Biology department at Linfield from 1941-1974.

Observations On The Hibernation Of Culex Tarsalis Coquillett In Utah Valley, Utah, Dennis W. Trent

Theses and Dissertations

Culex tarsalis Coquillett is a common evening pest mosquito throughout the summer in most of temperate Western North America. Present evidence indicates this mosquito as the principal naturally infected vector of western equine encephalomyeltic (WEE) viruses. Certain interrelationships of WEE epidemiology and tarsalis bionomics are basically understood; however, in areas where winters are severe little is know of tarsalis hibernation, and the survival mechanism for WEE viruses in unknown. The purpose of this study, conducted from 1 September 1959 to 20 May 1960, was to gather ecological information on the hibernation of Culex tarsalis in Utah Valley, and secondly to …

Fluctuations Of The Clover Seed Chalcid, Bruchophagus Gibbus (Boh.), And Other Alfalfa Insect Populations In Cache Valley, Utah During The Summer Of 1958, Keith C. Tilley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The clover seed chalcid Bruchophagus gibbus (Boham) as it is presently classified, was originally described by Howard, in 1879 as Eurytoma funebris Howard (Comstock 1880). Kolobova (1950) reported different races of chalcid on clover and alfalfa in Russia. Studies are presently being conducted in the United States to see if these are applicable to our fauna, Burks (1960).

Insect Pollinators Of Carrots In Utah, George E. Bohart, William P. Nye

All PIRU Publications

IN THE course of observation at Logan, Utah, on the occurrence and pollinating activities of insects on carrots grown for seed, 334 species representing 71 families, were collected. Most numerous in species were the hymenopterous families and superfamilies Sphecidae, Apoidea, Psammocharidae, Vespidae, and Ichneumonidae, and the dipterous families Syrphidae, Tachinidae, Bombyliidae, Stratiomyidae, and Sarcophagidae. Most numerous in individuals were the dipterous families Syrphidae, Ceratopogonidae, Chloropidae, and Piophilidae and the coleopterous family Coccinellidae. Families and superfamilies represented by the most efficient pollinators were Apoidea, Sphecidae, Syrphidae, and Stratiomyidae. Abundance times efficiency was used as a pollination index for each species. On …

Distance From The Apiary As A Factor In Alfalfa Pollination, M. D. Levin, George E. Bohart, William P. Nye

All PIRU Publications

Experiments conducted in northern Utah indicated that the distribution of honey bees (Apis mellifera L.) on an alfalfa field is modified by various influences besides distance from the colonies. Because of these other factors, generalizations concerning the effect of distance from colonies on the distribution of foraging honey bees cannot be made on the basis of experiments herein reported. A slight negative relationship between bee populations and distance from colonies in alfalfa fields was found in some of the experiments reported. In two fields where the distance was less than 600 feet, horizontal stratification of the field population …

Descriptions, Biology, And Notes On The Identification Of Some Trogoderma Larvae, R. S. Beal Jr.

Ba

For several years members of the dermestid beetle genus Trogoderma have attracted widespread attention, particularly since T. granariurn Everts, the khapra beetle, became established as an introduced pest in Arizona, California, Mexico, and New Mexico. This species has been the object of a control program to remove it as a hazard to stored grain and to prevent its spread to parts of the country where it is not known to occur. Species of Trogoderma other than the khapra beetle may also build up to damaging numbers in stored products. Information has been obtained on these species, as well as on …

Insect Pests : Aphides, Clee Francis Howard Jenkins

Safflower : An Oil Crop For The Kimberleys, D F. Beech

Journal of the Department of Agriculture, Western Australia, Series 4

EXPERIMENTS with irrigated safflower carried out at the Kimberley Research Station have shown that the crop is well adapted to the local conditions.

In recent years yields of 2,000 to 3,000 lb. per acre have been generally obtained. Oil content of the main variety under trial varied between 33 and 35 per cent.

Locally produced safflower oil could help to make the Australian paint industry largely independent of imports.

Safflower meal is a protein-rich concentrate and could have considerable impact on the Kimberley cattle industry.

Safflower is likely to play an important part in the early development of irrigation agriculture …

Fruit Fly, D G. Shedley

Journal of the Department of Agriculture, Western Australia, Series 4

FRUIT fly control is compulsory! To obtain effective control of fruit fly it is necessary to combine strict orchard hygiene with bait spraying.

In addition, cover spraying with DIPTEREX will give extra protection to stone fruit and pears.

When the breeding powers of the fruit fly are considered it is easy to understand why home growers and orchardists need to fight a continual battle against this pest.

Insect Pests : Snails And Slugs, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

WHILE snails and slugs are not insects, they have been included in this series of articles, because the damage they cause is very similar to that caused by insect pests—and furthermore, the task of testing and recommending control measures is usually left to the entomologists.

Dried Fruit And Meal Insects, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

DRIED and preserved foodstuffs such as raisins, currants, oatmeal, nuts, and flour are often found to be "weevily" after long storage.

Strictly speaking, the term "weevily" should be applied only to material attacked by certain types of beetles, but the expression is now popularly used in connection with practically any insect infestation of stored products.

Fruit Fly Control With Rogor 40 And Lebaycid : Progress Report, D G. Shedley

Journal of the Department of Agriculture, Western Australia, Series 4

THE Mediterranean fruit fly has been present in Western Australia for over 60 years and during that time many types of insecticides have been tested against the pest.

Traps and lures were amongst the earliest control measures adopted, but these gave way to sugar solutions poisoned with such materials as arsenic and sodium fluosilicate.

Insects And Mites Found Attacking Cereal Crops In Western Australia, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

ONE of the most important factors influencing Western Australian agriculture in the last 20 years has been the development of permanent pastures together with the associated practice of ley farming.

Although the increased use of pasture plants, and particularly subterranean clover, has increased the general fertility of many areas it has also accentuated various problems, including those relating to insect control.

Summer fallow was a strong deterrent to such pests as the red-legged earth mite, the lucerne flea, and webworm and these and several other creatures have shown a tendency to increase under new farming methods.

Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

INTEREST in the agricultural potential of the Kimberley region in Western Australia dates from its early exploration and settlement in the last century.

Several farming development schemes were considered for the area, but were never implemented.

This could be mainly attributable to lack of knowledge of agricultural potentialities, limitations of the local environment and ways of exploiting the local environment.

Up to the present the economy of the region is almost entirely based upon the extensive production of beef and to a lesser extent, wool.

Termites Or White Ants, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

TERMITES are commonly but erroneously called "white ants."

Actually they are more nearly related to cockroaches than to ants, but their general appearance and subterranean habits have given strong support to the popular designation.

They may be divided into two major groups from an economic point of view, viz., wood-dwelling and earth-dwelling termites.

Grasshoppers And Locusts In Western Australia, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

GRASSHOPPERS and locusts are among the most ancient enemies of the farmer, for they figured prominently in Biblical times, and periodically throughout the ages have devastated crops in all parts of the world.
