Insect Pest - Aphides, C F.H Jenkins
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
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.
White Cabbage Butterfly
Journal of the Department of Agriculture, Western Australia, Series 3
During January a consignment of small wasp which parasite the white Cabbage Butterfly were received in this State from the C.S.I.R.O., Canberra, and were released on cabbages in the Coogee area.

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
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
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.
