Weevil Management In Orchards And Vineyards Looks Promising, Stewart Learmonth

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

Research and monitoring undertaken by Agriculture Western Australia is showing that the management of weevils in Western Australia's orchard crops and vineyards is improving. A number of alternative management strategies are being implemented, and future research will assess the effectiveness of non-chemical approaches to weevil management.

Tomato Spotted Wilt Virus And Its Management, Lindrea Latham, Roger Jones

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

In 1993, western flower thrips, an important pest of horticultural crops, was found in Western Australia. Since then there has been an upsurge in damsging virus disease epidemics caused by tomato spotter wilt virus in horticultural crops. This has occurred because western flower thrips is a more effective vector of tomato spotted wilt virus than other thrips species. Lindrea Latham and Roger Jones outline the symptoms, spread and management of this serious virus disease in vegetables and ornamentals.

The European Wasp : A New Threat To W.A, Department Of Agriculture, Western Australia

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

The European wasp was detected in Western australia for the first time in January and February 1977 in the metropolitan suburbs of Mosman Park, Cottesloe and Attadale.

So far it has only been found within an area of 8 km radius from Fremantle but the outer boundries of the infestation are still uncertain.

It is Department of agriculture policy to eradicate the European wasp, if possible, and to destroy all nests detected.

W.A. Alert For Aphid On Lucerne, Department Of Agriculture, Western Australia

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

The spotted alfalfa aphid which is devastating lucerne crops in the Eastern States, could be introduced to Western Australia on lucerne hay which is fed en route to imported livestock. The Department of Agriculture has therefore alerted all inspection points about the possible danger.

The Department of Agricultureis maintaining traps specifically for the aphid, and has found no evidence of it yet.

Virus Diseases In Agriculture, George Mclean

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

Viruses are extremely small particles which can only be seen with an electron microscope. A virus is present in a diseased plant as huge numbers of tiny particles within the cells of the plant. Viruses which are infectious can cause disease, and reproduce only inside the cells of a living plant.

Many insects transmit plant virus diseases—aphids, leafhoppers, mealy bugs, thrips and beetles. Generally a virus is spread by only one of these groups of insects.

The Western Australian Department of Agriculture is expanding the diagnostic service for the identification of plant viruses.

Warning : Another Dangerous Webworm Season Possible, Department Of Agriculture, Western Australia

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

Heavy webworm moth flights in most wheat-growing areas during April, and favourable conditions early in the season, have made this year a potentially hazardous one for webworm infestations in cereal crops.

Thrips Damage Of Grapes, A N. Sproul

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

IN mid-December, a few bunches of Semillon grapes were submitted for examination from a Caversham Vineyard.

Damage to grape berries by thrips has not been recorded before in Western Australia.

Successful Commercial Beekeeping, R S. Coleman

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

THE eye of the master fattens the cattle. One of the oldest farming proverbs this is as true of bee-keeping as any other branch of farming.

Careful husbandry is the basis of all successful bee-keeping; anything else is secondary.

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.
