How it works

How it works

When the formulated products of HearNPV is applied to crops and ingested by pests, the virions are released and replicate massively in the pest's body, and then spread throughout the body while rapidly consuming body tissues. Helicoverpa spp that ingest the virus become lethargic during their sickness caused by the virus infection, and appear sublethal. Eventually, they will die with their internal organs and tissues liquefied. In addition, the virions will continue to spread like a plague between and through several generations of Helicoverpa spp through the fluid or feces of the dead Helicoverpa spp larvae, providing effective long-term control of the Helicoverpa spp population.
