Before we got to venture into the habitat models in the Learning Center, we got to learn about pest control from a Dr. David Morgan. He had a British accent I believe? Any who it made the mini-lecture more enjoyable, at least for me seeing as how I love accents especially British ones.
Here are some notes from the lecture:
- find a predator or pathogen that kills the insect/pest.
- has to reproduce more rapidly than the pest to control it
- the solution predator must be tested in the new climate to which it has been relocated to make sure that it will survive where the problem prey is habituating
- has to be tested to make sure it only preys on the pest
- lots of tests done in quarantine
- have to apply for a permit to bring in the new predator, requires 75 pages of research: geographic range, etc.
- have to do follow up studies after pathogen/predator released
- Permit goes through. find a way of producing/storing/releasing the good pathogen/predator.
- hard to control pests in urban areas, most insecticides not allowed in urban areas
- birth of bio-control @ University California Riverside
- Santa Ana Sucker-threatened fish, so impacted by pollution, human development
- the district propagates the fish and releases(populations separated genetically because of adaptations to certain habitats)
- Brown Headed Cowbird-Invasive species. parasite nests of other birds
- double door system to avoid infestation
- overpopulation? species within a habitat will naturally downsize (talking about the fish)
- Agriculture can't succeed without good soil and access to water
- And the craziest thing my guide said that I don't know if it's true but it certainly got my attention and sorry for the run on sentence was "There are more organisms in a handful of soil than people on Earth."
Here are some shots I took at the Learning Center:
