Popis: Bacillus thuringiensis var israelensis (BTI), when ingested by mosquito larvae, is highly toxic to them. Many other aquatic invertebrates feed on bacteria but, in general, BTI is not toxic to them. We tested in the laboratory the hypothesis that certain crustaceans indirectly benefit mosquito larvae by reducing mortality caused by BTI. We presumed the mechanism to be ingestion of the bacteria by the crustaceans resulting in a lower concentration available to the mosquito larvae.
