Insects will use a host plant especially in a monoculture. They usually use a plant that is unhealthy.

If the way a plant looks to an insect can be determined.

I believe there is two areas of plant health that can be opened up.

One being to understand where the introduction of any given insect appears and then to stop insect presents before them turning into an insect plague.

It also can determine other health issues with a plant to the why it makes a plant look attractive to the insects to start with.

The starting point of this science has been happening for 1,000's of years and that is to look for a weak plants or a plant being attacked by insects in the daylight environment.

Many plant growers have used known insect host plants, as plant to protect their plants of real interest.

For all I know someone has already made some head way in this area but I find it a fascinating area of plant health. Being through the eyes of an insect or a eye of a person.
