All these processes function synergetically, and enable aphids to feed on high-sucrose-concentration plant sap, as well as to adapt to varying sucrose concentrations. [ 38 ] Plant sap is an unbalanced diet for aphids, as it lacks essential amino acids , which aphids, like all animals, cannot synthesise, and possesses a high osmotic pressure due ...

The presence of the aphids weakens the tree by decreasing growth rates and making it more susceptible to attack by other pests such as the spruce beetle (Dendroctonus rufipennis). Serious defoliation can kill the ...
