US Vineyards Battle Invasive Spotted Lanternflies Threatening Wine Industry
Vineyards across the United States are grappling with the spread of spotted lanternflies, an invasive insect species that poses a significant threat to grape production. First detected in Pennsylvania in 2014, these insects have now spread to 19 states, primarily affecting the northeastern region. The lanternflies feed on the sap of grapevines and other plants, secreting a sugary liquid that promotes the growth of sooty mold, which can damage crops and reduce yields. This has led to substantial economic concerns for the wine industry, with some vineyards reporting a 50% reduction in grape production. Efforts to control the population include physical removal of the insects and their egg masses, as well as the use of insecticides, although options are limited close to harvest time.
