Biological Control Of Paterson's Curse, John Dodd, Bill Woods

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

The long- delayed biological control programme for the weed Paterson's curse (Echium plantagineum) has begun with the release of the leaf mining moth (Dialectica scalariella)' an insect slightly bigger than a mosquito. Yhe caterpillar stage of the moth feeds inside the leaves, producing tunnels and chambers which damage the leaf.

The leaf mining moth has already become established in suitable areas. Although the familiar purple haze of Paterson's curse will continue to be seen for years to come, we expect that the leaf mining moth - and other agents yet to be released - will make it a more manageable …

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.

Hexagenia Mayflies: Biological Monitors Of Water Quality In The Upper Mississippi River, Calvin R. Fremling

Journal of the Minnesota Academy of Science

ABSTRACT-Analysis of Hexageniamayfiy distribution patterns has proven to be a simple, inexpensive method of monitoring water quality in the Upper Mississippi River. Burrowing Hexagenia nymphs live at the mudwater interface intimately associated with organically enriched sediments that have a strong affinity for contaminants. By their presence or absence in silted habitats, they assess the synergistic effects of hypoxia, toxins, and other stresses throughout the year. Adults are large and easily collected, providing inexpensive water quality monitoring on a river so large that comprehensive chemical, physical, and biological analyses are not logistically feasible or affordable. Pollution abatement in metropolitan Minneapolis-St. Paul …
