Insect Pest - Aphides, C F.H Jenkins Sep 1952

Insect Pest - Aphides, C F.H Jenkins

Journal of the Department of Agriculture, Western Australia, Series 3

The members of the aphis family are remarkable creatures both in structure and habits. They are practically world-wide in their distribution and despite their small size and apparent fragility they thrive under a wide variety of conditions and are among the most prolific breeders in the animal kingdom.

Insect Pest - The Red-Legged Earth Mite, C F.H Jenkins Jul 1952

Insect Pest - The Red-Legged Earth Mite, C F.H Jenkins

Journal of the Department of Agriculture, Western Australia, Series 3

The red-legged earth mite is not a true insect, but is included in this series because the injury caused by the mite is very similar to that done by many insects and because the study of ticks and mites and their control is usually the work of an entomologist.

The European Corn Borer Situation In South Dakota Spring 1952, Gerald B. Spawn Jun 1952

The European Corn Borer Situation In South Dakota Spring 1952, Gerald B. Spawn

Agricultural Experiment Station Entomology Pamphlets (1940-1952)

The European corn borer, which has now assumed the role of "perennial pest" in South Dakota, has been conspicuous by its inactivity during the past few months. However, it is still the major pest of corn in our state. Since last fall the larvae (worms) have been spending their time in the "deep freeze" sleep of their kind of hibernation, hidden away in the snow-blanketed stalks of last years corn fields. This is nature's way of taking care of them during the winter, and all too many of the larvae are now becoming active again.

Snails And Slugs, C F.H Jenkins May 1952

Snails And Slugs, C F.H Jenkins

Journal of the Department of Agriculture, Western Australia, Series 3

Before giving any details concerning these pests, it will be well to explain that slugs and snails are, of course, not insects. They have been included in this series of articles, however, because the damage they do resembles very much that done by various insects and because the lot of recommending control measures usually falls to an entomologist. The snail could more correctly be called a shellfish than an insect as it is a true mollusc, but one which has become adapted to a life on land instead of in the water.

The Webworm, C F.H Jenkins Mar 1952

The Webworm, C F.H Jenkins

Journal of the Department of Agriculture, Western Australia, Series 3

The popular name webworm has been applied to a small caterpillar whose depredations in ploughed-in wheat crops have concerned farmers in this State for many years. The first record of the insect as a pest was made by Newman (1927) under the scientific name of Sclerobia tritialis Wlk. and it has been referred to as such in all subsequent Departmental publications. Recent investigations, how-ever, suggest that either more than one species of insects is covered by the term webworm or that the true webworm is a Crambid moth known as Talis pedionoma Mayr.

Argentine Ants Mar 1952

Argentine Ants

Journal of the Department of Agriculture, Western Australia, Series 3

Specimens of ants submitted in February by the Rockingham Health Inspector were identified as Argentine ants, these being the first recorded from this area. Two areas of infestation are present in the Rockingham townsite—one adjacent to the hotel and the other near the Fisher Street jetty. Active steps were taken by the local authorities to bring the infestation under control.

A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller Jan 1952

A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller

Bulletin of the University of Nebraska State Museum

Until rather recently little has been known of the Drosophila species of Nebraska. Sturtevant (1921) lists Nebraska as one of seven states from which no Drosophila had been reported. Patterson and Wagner (1943) show that collections of Drosophila pseudoobscura had been made in the vicinities of Scottsbluff and Kearney, but no other Drosophila species are reported from Nebraska in their publication.

Insect Pest And Their Control, C. F. H. Jenkins Jan 1952

Insect Pest And Their Control, C. F. H. Jenkins

Journal of the Department of Agriculture, Western Australia, Series 3

Methods of insect control are sometimes classified under the four following headings—Quarantine, Cultural Methods, Biological Control and Chemical Treatments. Each method has its own particular part to play in preventing the spread and multiplication of insect pests and it is essential for maximum results that everyone—whether he be a commercial grower or a backyard gardener—has a general understanding of the principles involved.

Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma Jan 1952

Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma

Bulletin of the University of Nebraska State Museum

In 1948 the insect collections at the University of Nebraska State Museum were placed in the care of the author. Prior to that date curatorial duties were assumed or assigned to full time teaching or research staff members. As would be expected under the latter circumstances, the organization of study material and types was neglected in many families and genera. Since 1948 type material, because of its intrinsic value, has received considerable attention. All primary and representative secondary types have been assembled in three museum cases and one slide cabinet for curatorial and study convenience.
