SAG performs unprecedented release of biological controller against Lobesia botrana in Chillán

The use of 20 thousand copies of Campoplex capitator in Chillán adds to the more than 276 thousand transmitters of sexual confusion installed in 13 communes to control the plague in urban areas of the Ñuble Region.

In an unprecedented effort in the country to control the Lobesia botrana plague in urban areas, the Agricultural and Livestock Service initiated the release of the Campoplex capitator microwasp in home vines in Chillán, a measure that adds to the more than 276 thousand emitters of sexual confusion installed in 13 communes in the Ñuble Region.

These are two tools that are friendly to the environment and harmless for people and animals, aimed at eliminating the grapevine cluster moth in home vines and reducing the pressure of the pest on vineyards and blueberry orchards.

"Our goal is to eradicate the grapevine cluster moth from urban areas of the Ñuble Region, reinforcing the protection of vineyards and orchards that may be affected by this pest," explained SAG Regional Director Eduardo Jeria .

A total of 20 thousand specimens of Campoplex capitator will be used in urban control in the city of Chillán, starting with the installation of 8 thousand wintering pupae during September and the release of 12 thousand adult specimens between October and December.

The microwasp Campoplex capitator is a very small insect that only affects Lobesia botrana, parasitizing its larvae and eliminating them. It is considered the main natural enemy of the plague in Europe. The first specimens brought to Chile were collected in Italy in 2015 and raised in the Lo Aguirre laboratory of the SAG, making the first release in 2018.
