This can be a complicated answer. Of course the least toxic method is to use some form of IPM, or Integrated Pest Management strategy. Here is a reprint from a training class from the University:

Here is a publication that discusses pollinators and the agricultural chemicals we use to protect our plants. At the end of the article is a list of various chemicals and their toxicity threat to insects:
