Chemical Control Agents Used Against the Gypsy Moth

Gypsy's moth, a chemical control agent for Lymantria dispar, is a highly destructive species that can play a unique role in many living creatures and fulfill it. These creatures include various deciduous trees and shrubs, wildlife species of the same environment, as well as humans. Gypsy's moth destroys the beauty of forests through the leaves, changes the habitat of ecosystems and wildlife, and destroys our own lives. Therefore, the United States is not surprising.

After the first introduction of Massachusetts from Europe and Asia in 1869, an attempt to eradicate Lymantria dispar began in the late nineteenth century. These do not prevent the gypsy moth from being established, the population continued to spread from the east to the west of North America. Between 1978 and 1998, gypsy moths were captured in 120 locations in British Columbia, Canada, and 20 eradication programs were initiated. In 1992 the biggest gypsy eradication program in British Columbia captured 17 Asian gypsy moths and sprays 3 times the microbial pesticide Btk to 20,000 hectares. The use of microbial pesticide Btk to spray gypsy moths in urban areas is often associated with strong civil protests and these eradication attempts are controversial. The cost of the program is estimated at $ 6 million

Gypsy's population is periodic. Generally, the population reaches the rate of epidemic within a few years and then drops to a low level in the next few years. The whole cycle may change from 3 to 10 years. At low density, gypsy moth is regulated by natural enemies like parasites and parasite vertebrates, especially small mammals, but it is not destroyed. As the population increases beyond the control of these natural enemies, gypsy moths are regulated by different causes of death, mainly diseases and starvation. Among these two factors, diseases caused by nuclear polyhedrosis virus (gmNPV) and ginseng moth (Entomophaga maimaiga) caused the collapse of the gypsy moth epidemic population. Generally, the outbreak is 2 to 5 years, and the actual outbreak may be 1 to 3 years. Factors regulating the epidemic in these areas and the collapse of the population of gypsy are unknown.
