Biological pest control The different ecosystems at the Biodôme are also home to insect pests and mites that prey on plants. How do we control them? affPhoto("aphids on a spruce", "112puceronEpinette.jpg", "", "208", "136"); ?> affPhoto("tropical cochineals", "112cochenilleTropicale.jpg", "", "208", "136"); ?> affPhoto("cochineals", "112cochenilleFarineuse.jpg", "", "208", "136"); ?> affPhoto("acarids on a spruce", "112acarienEpinette.jpg", "", "208", "136"); ?> affPhoto("entomologist", "112SusanJohnson.jpg", "", "218", "150"); ?> With biological pest control, that is by intentionally introducing natural enemies (predators) of these pests into the ecosystems. affPhoto("ladybird larva", "112larvecoccinelle.jpg", "", "254", "196"); ?> This allows us to control the pests without eliminating them completely.
