N2 - Laboratory experiments have shown that the fitness of micro-organisms can depend on cooperation between cells. While this insight has revolutionized our understanding of microbial life, results from artificial microcosms have not been validated in complex natural populations. Here, we investigate the sociality of essential virulence factors (crystal toxins) in the pathogen Bacillus thuringiensis using diamondback moth larvae (Plutella xylostella) as hosts.
