Under laboratory conditions, the psyllid Aphalara itadori has demonstrated its potential to be a Climate change successful biocontrol agent for F. japonica. However, this potential has not materialised in the field where long- Fallopia japonica term establishment of A. itadori has been unsuccessful and faces the added challenge of climate change. Intraspecific variation Intraspecific variation (variation among individuals of a species) has been shown to support establishment in Invasive species alien species and improve resilience to changing environmental conditions. Here we propose it could improve Japanese psyllid Saturation Deficiency Index the performance of biocontrols. To test this possibility we compared the performance and impact on F. japonica of three strains of A. itadori with different genetic backgrounds, including a newly created hybrid. Wehy- pothesize that genetic variability would be increased in hybrids resulting in greater biocontrol effectiveness (greater impact on plant growth). We also explored the potential influence of changing climate on performance, testing all strains under two humidity conditions (with the same temperature). -
Weed of Interest: Japanese Knotweed
Weed of Interest: Japanese Knotweed Andy Senesac, Weed Science Specialist, Cornell Cooperative Extension of Suffolk County Japanese knotweed is a vigorous, herbaceous peren- nial weed . Having a deciduous habit, it dies back to the ground every fall and regenerates new shoots every spring from a robust system of underground stems (rhizomes) and crowns . Japanese knotweed com- monly invades disturbed areas with high light, such as roadsides and stream banks . New infestations oc- cur mostly vegetatively (rhizomes and stem pieces) but some viable seed dispersal also occurs . The stem is hollow with nodes surrounded by papery sheaths (ochrea) . These nodes are always enlarged and notice- able . The original genus name of Polygonum is a Greek word meaning ‘many knees’ – referring to the nodes which resemble knees . The leaves are alternate, wide and broadly ovate . Flowering occurs in late summer, when small, white flowers showily develop in the axils of the leaves . Knotweeds are dioecious and have male and female flowers on separate plants. The original in- festing plant brought from England in the 1800s was a female plant and many of the current infestations in the northeast are thought to be clonal offshoots of this Japanese knotweed cutaway view of hollow stem original plant . northeast US and Canada .
