Gypsy moth update January 2016
Production of in vivo virus
From the pathogen complex of the gypsy moth (Lymantria dispar) the insect pathogenic virus LdMNPV from the Baculoviridae family shows the greatest potential to be used as biological control agent (BCA) to reduce gypsy moth populations. In the BIOCOMES project we are working on a LdMNPV-based formulation with high efficiency in the reduction of gypsy moth populations in deciduous trees.
To produce LdMNPV an insect rearing has been set up at the BIOCOMES partner Andermatt Biocontrol. At this moment a stable and continuous rearing of L. dispar has been realised. The production of the virus is running and several LdMNPV isolates have been propagated and tested in bioassays. The isolates are being held in a virus bank. This virus bank will be used to select the most appropriate isolate for the biological control agent to control gypsy moth.
Our next steps are to further improve and automate the rearing and to test the efficacy of the different isolates in laboratory experiments and field trials and to initiate molecular and biological characterization of the isolates. The most promising LdMNPV isolate will be used to formulate the final product.
