Development of a viral biopesticide for the control of the Guatemala potato tuber moth Tecia solanivora.

The Guatemala potato tuber moth Tecia solanivora (Povolny) (Lep. Gelechiidae) is an invasive species from Mesoamerica that has considerably extended its distribution area in recent decades. While this species is considered to be a major potato pest in Venezuela, Colombia, and Ecuador, currently no specific control methods are available for farmers.

An isometric virus of the potato tuber moth Tecia solanivora (Povolny) (Lepidoptera: Gelechiidae) has a tri-segmented RNA genome.

A small isometric virus has been isolated from larvae of the Guatemala potato tuber moth, Tecia solanivora (Povolny), collected in Ecuador. It was designated the Anchilibi virus (AnchV). The non-enveloped viral particles have an estimated diameter of 32+/-2 nm.
