South-West Medlfy Study Highlights Improved Control Strategies, Sonya Broughton, Francis De Lima
South-West Medlfy Study Highlights Improved Control Strategies, Sonya Broughton, Francis De Lima
Journal of the Department of Agriculture, Western Australia, Series 4
Mediterranean fruit fly has become an extremely important pest of commercial orchards in recent years, with there being numerous reports of control problems from fruit growing districts in the South-west of Western Australia. To assist in finding a solution to the problem of effective Medfly control, a study commenced in July 1995 to develop further understanding of Medfly ecology and to evaluate control strategies under varying climatic and management conditions in the South-west region. Sonya Broughton and Francis De Lima report on the outcomes of the three-year study.

Integrated Control Of Soil Insect Pests Of Potatoes, Stewart Learmonth, John Matthiesson
Integrated Control Of Soil Insect Pests Of Potatoes, Stewart Learmonth, John Matthiesson
Journal of the Department of Agriculture, Western Australia, Series 4
One of the more difficult aspects of growing potatoes in Western Australia is controlling soil insect pests. These pests have become more troublesome because the highly effective and persistent organochlorine insecticides previously used to control the main soil pests, African black beetle and whitefringed weevil, were deregistered for agricultural use in 1987. Entomologists from the Department of Agriculture and CSIRO in Western Australia are collaborating to develop new management strategies for these pests that rely less on the use of chemical insecticides

The Queensland Fruit Fly Eradication Campaign, G P. Ayling
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australia has started an extensive eradication campaign against the Queensland fruit fly, one of the worst horticultural pests in the world.
The programme, the largest of its kind in Australia, and one of the biggest in the world, involves the integration of three tequniques for fruit fly control: lure trapping, protien baiting and the release of sterile male flies.
Selecting New Kinds Of Dung Beetles For Better Bush Fly Control, T J. Ridsdill-Smith
Selecting New Kinds Of Dung Beetles For Better Bush Fly Control, T J. Ridsdill-Smith
Journal of the Department of Agriculture, Western Australia, Series 4
Native dung beetles are found in south-western Australia, but they are largely restricted to areas of natural vegetation where they feed on dung pellets of marsupials.
When European man cleared the land, planted pastures and introduced cattle, he created a new type of environment which did not suit most native beetles. Cattle dung accumulated, and the bush fly Musca vetustissima, found this a very favourable breeding site.
In an attempt to correct this inbalance, other types of dung beetles addapted to living in open pastures are being introduced by CSIRO. These introduced beetles can reduce fly numbers by increasing the …

New Control For Esperance Armyworms, G R. Strickland, G. D. Rimes
New Control For Esperance Armyworms, G R. Strickland, G. D. Rimes
Journal of the Department of Agriculture, Western Australia, Series 4
Armyworms are periodically responsible for serious cereal crop damage in Australia, often causing up to 80 per cent crop loss.
Amajor outbreak at Esperance in 1975 resulted in some 14,200 ha requiring treatment.
This was the first serious outbreak of armyworm for nine years in Western Australia.
A major new problem in the control of armyworm outbreaks is that use of DDT has been restricted by residue and withholding period problems, especially with a crop such as barley in which the grain is unprotected by glumes.
The trial results suggest that trichlorfon is a suitable material to eradicate armyworms and …

Control Of Insects In Cotton, D G. Shedley, D. L. Hardy, P. J. Michael
Control Of Insects In Cotton, D G. Shedley, D. L. Hardy, P. J. Michael
Journal of the Department of Agriculture, Western Australia, Series 4
Results of two experiments at the Ord Irrigation area in 1968 indicate that farmers may be spending more than necessary to obtain economic control of cotton pests in some seasons.
One experiment clearly demonstrated the relationship between low insect numbers and improved cotton yields—the second indicated that a moderate but well timed spray schedule, especially during the early part of the season, can result in more economic insect control than an intensive spray schedule.
Simple Treatment Will Protect Farm-Stored Grain, Department Of Agriculture, Western Australia
Simple Treatment Will Protect Farm-Stored Grain, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
WITH unusually large quantities of grain likely to be stored on farms this season, 1970 will be an important year for the control of pests in stored grain.
Infested grain from farms is responsible for almost all outbreaks of infestation in bulk storages, leading to costly treatment by the grain handling authority. Effective control on the farm would eliminate most of this.

Insect Pests Of Lawns., D G. Shedley
Insect Pests Of Lawns., D G. Shedley
Journal of the Department of Agriculture, Western Australia, Series 4
Lawns provide a home for many and varied insects. Although a large number do little or no damage there are some which, if left unchecked, will make it impossible to maintain the grass in good condition.
SPRAYING with insecticides is not always the best answer to pest problems. Manuring, cutting and watering must be maintained at proper levels. In fact, if this is not done the attacks of at least some pests will be more severe.

Insect Pests And Their Control, Clee Francis Howard Jenkins
Insect Pests And Their Control, Clee Francis Howard Jenkins
Journal of the Department of Agriculture, Western Australia, Series 4
METHODS of insect control are sometimes classified under the following four 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.
