Pieris rapae granulosis virus (PrGV) In Wuhan
The cabbage butterfly is beautiful. However, its larvae cabbage caterpillar can eat the cabbage seriously.
The farmers were very distressed, which caught the attention of Academician Gao Shangyin from Wuhan University. Under his call, scientific and technological personnel from all over the country sent the collected naturally dead cabbage caterpillar to Wuhan University. After screening through tens of thousands of dead insects, they finally found its natural enemy, pieris rapae granulosis virus (PrGV). PrGV also has a certain infectivity to the plutella xylostella, which can solve two important pests that appear simultaneously on cabbage. It has also been awarded the title of National Key New Product.
The birth of a baby by the butterfly is very special. It takes a lot of space to meet the needs of giving birth to a baby once, which is difficult for the teachers. However, Teacher Yin came up with a good solution and used an attractant to gather all the butterflies together, so that they could give birth to a baby. After using the pesticide PrGV, the butterfly dared not come again.
To make good use of the PrGV seed as a capable assistant, one must first see if there is a butterfly dancing, and secondly use the specialized attractant for the diamondback moth plus yellow board. Once adult is trapped, use PrGV within a week.
