Macrosipum albifrons is a species having rapid development
Colonies of M. albifrons develop rapidly on all the organs: inflorescences, pods and roots.
The damage caused on young flowers is serious because these aphids induce flowers to abort.
If the attack is a strong one, the plants die.
M. albifrons can transmit the bean yellow mosaic virus (BYMV).
Populations of M. albifrons are strongly regulated by entomophthoral mycoses.
