Took delivery of some 2 x 4 Spruce-Pine-Fir studs, building a small addition. Alot of this material has worm holes, or something that has been boring holes. Should I be concerned about strength or insects still being active ? Thanks.

If it what I think it is the best thing to do is to return the lumber and get some good material. If you do not your labor may end up as wood dust.
How much is alot?
What type of lumber has the holes in it?
What is the lumber going to be doing? Is it supporting a 25,000# load, or a 5# piece of vertical drywall.
It's easy to say return it, without giving the above questions any thought, but that might not be necessary. A few worm holes does not ruin a load of lumber.

If we can assume that the worms got to the wood when it was still in "tree" disguise, then it's probable that any that made it through the sawmill died in the kiln. So as long as the wood isn't structurally ruined, it shouldn't get any worse than it is now.

Have you ever visited a large sawmill?
Often the Kiln is simply a stop on the railroad tracks where wood is briefly heated up. They get to stamp KD on it once the wood reaches 19% moisture. depending on the time of year it is it may already be at 19% moisture or only take a few minutes to reach that (remember the tolerance is 2% so 21% moisture is still able to stamp KD)
In addition he didn't say it was KD not all wood sold is. Anotherwords there is a great chance that insect larva may still be present.. Now as to wiether that is critical is another matter.. If the wood quicky drops to 12% Moisture due to heating etc. insect larva wil die anyway.. they can't live without moisture present in the wood..
Each 8' stud has about 20 - 30 holes. The lumber is S-P-F and it is KD. Will be used for wall framing, one story addition. I think I am more concerned that the worms are still active. Termites are a problem here in southeast Virginia, I just don't want any type of insect chewing up my lumber.

Look and see if you have pine borers. They aree killing pines right and left in the south.

That is probably what I have. The holes are about 1/4" + in diameter, the tunnels run at all angles. I am sure that there is a grading rule for acceptance, maybe none are acceptable for #2 and better. Thanks for the link.

If you think worm holes are bad, just wait 'til the HVAC, plumbers, and electricians show up.
LOL
LOL, they got sum BEEG worms in their tool bag.
