The limitations of biological control and culture practices explained above have led to a strong dependence of farmers on insecticides as the main way of controlling CPB outbreaks. As an alternative, integrated pest management (IPM) approaches have been implemented in potato cultivation (VanderZaag2010; Alyokhin et al. 2015). IPM includes the combination of biological control, crop management practices, and chemical control. However, despite much talk about its benefits, IPM is still far from being universally adopted by commercial potato growers(Alyokhin 2009). There are no commercial cultivars on the market that show a strong level of resistance towards the CPB, although some level of avoidance is seen on the cultivar Dakota Diamond (Thompson et al.2008). It may be that also in other cultivars a low level
of CPB resistance is present. However, it is likely that
it remained unnoticed, as farmers will not tolerate the
presence of any beetle in their potato field. Incorporation
of host plant resistance into potato varieties may
be an effective tool in the management of CPB
