| background frequency of bacillus species at the canberra airport: a 12 month study. | anthrax, caused by bacillus anthracis, is a naturally occurring disease in australia. whilst mainly limited to livestock in grazing regions of victoria and new south wales, movement of people, stock and vehicles means b. anthracis could be present outside this region. of particular interest is the "background" prevalence of b. anthracis at transport hubs including airports. the aim of this study was to determine the background frequency of b. anthracis and the commonly used hoax agent bacillus t ... | 2015 | 26298416 |
| towards management of mosquitoes at homebush bay, sydney, australia. i. seasonal activity and relative abundance of adults of aedes vigilax, culex sitiens, and other salt-marsh species, 1993-94 through 1997-98. | the mosquitoes associated with 2 saline wetlands at homebush bay, sydney, australia, were investigated over 5 consecutive seasons. twenty-one species were collected in adult traps at the 2 sites but the saline wetlands supported larvae of only 4 species: aedes alternans, aedes camptorhynchus, aedes vigilax, and culex sitiens. of these, ae. vigilax and cx. sitiens were the most common, and their peak abundances generally occurred during february and april, respectively. both wetlands were influen ... | 1999 | 10412120 |
| trichogramma (hymenoptera: trichogrammatidae) ecology in a tropical bt transgenic cotton cropping system: sampling to improve seasonal pest impact estimates in the ord river irrigation area, australia. | trichogramma westwood (hymenoptera: trichogrammatidae) cause high mortality rates in the potentially resistant pest species, helicoverpa armigera (hübner) (lepidoptera: noctuidae), and are considered integral to the resistance management plan for bacillus thuringiensis transgenic cotton, gossypium hirsutum l., production in the ord river irrigation area (oria), western australia. measured as percentage of parasitism, trichogramma activity seems highly variable over time; yet, it contributes sign ... | 2009 | 19610415 |
