Anton,

To me, there's no difference between a "tomato fruit borer" and a "perforador del fruto del tomate" except the language. As a representative of CABI, you undoubtedly have access to those excellent but relatively expensive data bases. I suggest you consider demonstrating the value of subscribing to the rest of us (I myself am familiar with them), by posting one or two citations related to Neoleucinodes elegantalis as an example.
