New Moth Threatens Ladakh's Fragile Economy
8 May
Summary
- A non-native moth, Phalera cf. bucephala, has invaded Ladakh.
- Larvae can strip willow trees bare, impacting local resources.
- Climate change is creating a hospitable environment for invasive species.
The fragile landscapes of Ladakh are now contending with an invasive species: the buff-tip moth (Phalera cf. bucephala). Scientists have documented its presence in the Suru Valley of Kargil district, a region traditionally known as a cold desert but experiencing gradual warming. This climate shift is fostering a more hospitable environment for invaders.
The larvae of this moth are voracious feeders and can decimate host plants, particularly the white willow (Salix alba), locally known as Kralboo. This tree is crucial for roofing material and livestock fodder. The study indicates that complete defoliation can occur within 30 days, posing a severe threat to vegetation.
Researchers observed the moth's presence spanning the valley from Minjee to Parkachik. They warn that without timely control measures, the invasive pest could spread to fruit-growing areas. The study links this outbreak to a broader ecological trend of increased insect pest invasions in the region, with at least six other invasive species recorded previously.
