Hey Ruralguy.
So, I've setup the database so there's a set list of survey types (in "Survey types" table) to choose from to populate the Survey Type field of the "Protocols" table. See screenshot of protocols table. When we add a new pest record (via my Data Entry form, or by me going into the backend and just populating the tables), we'll already have researched the species and know what types of surveys are available. As you can see in the screenshot, there are usually only 1-4 survey types applicable to the species (from the ~10 possible types). I'm not sure if this answers your question.
One more thing: perhaps this is obvious, but a particular survey type (e.g., pheromone) for a particular pest (e.g., blackheaded budworm) is not the same as that same survey type for a different pest (e.g., pheromone for spruce budworm). The "Overview" (description) will be specific to each case.
