| variability and genetic basis for migratory behaviour in a spring population of the aphid, aphis gossypii glover in the yangtze river valley of china. | the population dynamics, development of gonads, takeoff and flight behaviour of aphis gossypii glover were investigated in order to test whether there was variation of migratory ability in the spring population. field surveys showed that not all the aphids overwintering on hibiscus migrated to the secondary host plants, and the host-alternating and host-specific life-cycle forms coexisted in nanjing, china. substantial variation in flight capacity of winged individuals, development of gonads and ... | 2008 | 18826665 |
