Abstract

Water-logged soil could be a major factor affecting populations of the ragwort biological control
agent, Longitarsus flavicornis , in Australia. Survival of L. flavicornis larvae in potted ragwort
plants after inundation with water for up to 264 h (11 days) was compared to larval survival in
control plants not exposed to inundation. Probit analysis indicated that 35.6% mortality of the
larval population occurred after 24 h inundation and 50.4% after 72 h. As high mortality was
recorded at periods of inundation known to occur in the field, it is concluded that winter
flooding is likely to be detrimental to populations of L. flavicornis.
