Early season pests present a great challenge for pest decisions makers, as any disruption

to beneficials early in the season is likely to result in the flaring of pests and increase the

necessity for further sprays later in the season. Aphids have the potential to reduce yield,

create sticky cotton and are vectors for Cotton Bunchy Top Disease (CBT). The high levels

of resistance to a number of chemical groups in aphids mean that adherence to the Insect

Resistance Management Strategy (IRMS) and an effective whole farm Integrated Pest

Management (IPM) strategy for the management of aphids is critical.
