The efficacy of Distance Plus Ant Bait, containing the insect growth regulator pyriproxyfen, was tested in the field against two invasive ant species in northern Australia: African big-headed ant (Pheidole megacephala (F.)) and yellow crazy ant (Anoplolepis gracilipes (Fr. Smith)). Results were also gained for a third pest species, Singapore ant (Monomorium(More)
The residual efficacy of pyriproxyfen against Aedes aegypti (L.) was examined by treating 2-liter buckets with a range of rates of Sumilarv 0.5G (100, 10, 1, and 0.1 mg product/liter or nominal dose of 500, 50, 5, and 0.5 ppb active ingredient) under semifield conditions. Approximately every 2 wk, pupal emergence inhibition (EI) was measured by using Cairns(More)
The karyotypes of a female and of a male Presbytis cristatus are analysed. In the latter, there is a complex Y-autosome rearrangement. The phyletic position of this species, in relation to genus Colobus, previously studied, is proposed, considering the sequence of chromosomal rearrangements which occurred during their evolution. These rearrangements, in(More)
Some significant correlations are observed between the CNS activities of a series of 59 benzodiazepines and some calculated electronic indices. The parameters concerned are the net charge on the carbonyl oxygen atom of the lactam ring and the total molecular dipole moment, correlations with the latter index being superior. The utility of the observed(More)
The selection of ofloxacin-resistant mutants from susceptible wild-type bacterial populations was investigated by three methods. Resistant mutants selected from populations of Escherichia coli (NCTC 10418) and Staphylococcus aureus (NCTC 6571) by single-step passage at either four or eight times the MIC occurred at a frequency of less than 1 x 10(-10).(More)
Bistrifluron, a benzoylphenyl urea compound, was evaluated for efficacy against Coptotermes lacteus (Froggatt), a mound-building species in southern Australia. Bistrifluron bait (tradename Xterm) was delivered as containerized pellets inserted into plastic in-ground feeding stations implanted in the sides of mounds. Termites actively tunneled in the gaps(More)
