Do you know the story of beet armyworm and insect virus？
The beet armyworm is a widely distributed global pest that can migrate over long distances at an ambient temperature of 24 degrees Celsius. It can be seen that beet armyworms prefer hot to cold. Adults can fly continuously for 120 hours, and when they occur in large numbers, larvae also have the habit of migrating in groups. Scientists have isolated the spodoptera exigua nuclear polyhedrosis virus (SeNPV) from the naturally dead body of the beet armyworm, marking the beginning of their love and killing relationship.
To obtain the SeNPV, the first step is to raise the beet armyworm. In the fields, many chemical agents cannot kill them, but once indoors, they become delicate and sickly, making industrialization difficult for scientists.
Under the careful care of insect breeders in Wuhan Unioasis, it is possible to raise a large number of beet armyworms indoors, which has given rise to the possibility of the SeNPV saving human. Under the continuous field experiments of green pest control engineers, a targeted pest control system was formed.
In Hubei, it is necessary to hang beet armyworm attractants and traps in early May to monitor the occurrence time of its first generation. As long as its adult is caught, the SeNPV can be used within a week to truly maximize its effectiveness. It will be too late to use the SeNPV after you have seen the beet armyworm.
