Genetic correlations between life-history traits for northern (above the diagonal) and southern (below the diagonal) populations of Sitobion avenae.

Note: DT1-DT4, the developmental time of 1st to 4th instar nymphs; DT5, the total developmental time of nymphs; FEC, lifetime fecundity; POS, post-reproductive time; SPA, adult lifespan; RET, reproductive time; statistical significance of genetic correlations evaluated using likelihood-ratio tests;*, P **, P ***, P Genetic correlations between life-history traits for northern (above the diagonal) and southern (below the diagonal) populations of Sitobion avenae.
