We have shown that target site insensitivity in Australian Aphis gossypii via the R81T mutation is not the causal mechanism of neonicotinoid resistance despite overseas studies implicating such.

The frequency of neonicotinoid resistant Aphis gossypii Glover populations has markedly decreased from a high of 94% to a moderate 22% in a single season.

Day Degree update.Aphid management

Aphid management in particular looking at chemical options as there is industry concern over the high levels of neonicitinoid resistance in aphids (eg. Shield).

Aphis gossypii Glover (cotton or melon aphid) is an important pest of cotton due to its ability to reduce yield through feeding damage.
