Those are important questions. I'm pleased to hear about and in fact have been following the integrated pest management approaches, which I think are very important. There certainly is a more holistic sense these days than there was in the era in which DDT was used indiscriminately. As one of your members pointed out, it's still circulating and causing problems.
It's also very important to investigate bio-control measures. For example, going back to the lily beetle, which I mentioned in my presentation, there's some phenomenal work being done in the United States in introducing a European species of parasite that is phenomenally effective at bringing down population levels and increasing the mortality of the lily leaf beetle. We really need to explore such things here in Canada as well.
