Chile seeks to apply sterile insect technique in the control of Lobesia botrana

In the Lluta Valley, in the extreme north of Chile, the Agricultural and Livestock Service (SAG) inaugurated an experimental laboratory at the Center for the Production of Sterile Insects (CPIE), in order to evaluate this technique as a complementary control method. alternative to the Lobesia Botrana or grape cluster moth.

The SAG reported that although the importance of the pest is recognized worldwide, to date no country has used the Sterile Insect Technique (SIT) as a control tool. That is why the SAG of Arica y Parinacota, taking advantage of its experience with the fruit fly, built this pilot laboratory that went into operation in April.

The goal is to sterilize a large number of insects that are then released into the environment to compete with natural populations, seeking to reduce or lose their ability to reproduce. In this way, the success of its application depends on the number of sterilized insects, their quality as a product and their competitiveness with respect to wild insects.

The laboratory has 120 square meters where the experimental production of the vine moth will be allowed. Here it is intended to know more about its biology and characteristics, which make it a viable option in the framework of the TAR.

It also seeks to achieve the determination of efficient diets and the necessary procedures to control the process and quality of this moth, with the purpose that in the future it could be an alternative for field control through its mass production.

Originally from Europe, the Lobesia botrana was detected for the first time in Chile in the area of ​​Linderos, Metropolitan Region. The plague attacks the vineyards and its larva causes direct damage by feeding on the bunches, resulting in the production and dehydration of the berries, which decreases the yields of the vines.

It should be noted that the CPIE is known worldwide for its capacity and knowledge in TIE, being the only existing center in Chile. Two months after the start of the work, it has managed to maintain and amplify the production of Lobesia.

Another benefit that the CPIE presents is its irradiating equipment, which will allow carrying out the necessary tests to determine the times and doses that will be required for the sterilization of the vine moth before being used in the field.

"Worldwide there is no information available that can be transferred as the Agricultural and Livestock Service has allocated the necessary resources for the implementation of an Experimental Laboratory to initiate the aforementioned studies, and the results of the establishment of TIE for Lobesia in Chile will depend on its results.", Highlighted the SAG.
