A new specie causes concern and it is a non-native gypsy moth. A Warning was issued by Washington (USA) after the appearance of specimens of the giant Asian hornet (Vespa mandarinia). The government, in fact, decreed a state of agricultural emergency.
As reported by Washington Governor Jay Inslee, Asian species (Lymantria umbrosa) have appeared in recent days, as well as European species (Lymantria dispar L.), pointing out that they are imminent danger of infestation.
In the statement, the authority notes that insects put the state’s agricultural and horticultural industries at serious risk and seriously threaten the economic well-being and quality of life of residents.
In parallel, Inslee notes that “according to the Animal and Plant Health Inspection Service of the United States Department of Agriculture, large infestations can completely defoliate trees.”
Following this, he concludes that “this defoliation can severely weaken trees and shrubs, making them more susceptible to disease. Repeated defoliation can lead to the death of large sections of forests, orchards, and gardens.”
