| Abstract: | b
Nymphs of Myzus persicae inoculated with Zoophthora phalloides were killed at each temperature tested in the range 10–22°C. Mortality was around 50% at 12, 15 and 18°C, but was considerably reduced outside this range. Deaths occurred soonest at 18°C (LT50—6.8 days). The low temperature requirement of this fungus limits its potential as a biocontrol agent for aphids in Australia. |
