Useful site for anything pest related, such as mosquitoes, ticks, spiders, etc. Any crop pest, or animal that stings, bites, transmits a disease, or is a pest is covered. In particular, the LRS search function is an amazing source of digitized books, documents, and journal articles. Their pest-related literature database is staggeringly complete, though it can be cumbersome to search through.

I just typed in the protozoan I work on and got 286 papers - can't wait to dig through and see what they have. Thanks for the link!!
