Lightbrown apple moth		Greenheaded leafrollers		Brownheaded leafrollers

All the pest leafroller species have many host plants. A valuable measure which can greatly assist with control is the destruction, mowing or grazing of host plants of leafrollers outside or within the orchard. Annual weeds and ground covers (dock, plantains, clovers) in the orchard are especially important for overwintering by the leafroller caterpillars. Mowing in summer and grazing in winter and early spring can substantially reduce leafroller populations on the ground cover plants. Similar benefits can be obtained by topping shelter trees which host leafrollers (e.g. willow, poplar, alder) to a manageable height; caterpillars may descend from these shelter trees onto the crop prior to harvest. Gorse and broom close to orchards may be a major source for immigrants of lightbrown apple moth; destruction of these plants can reduce the frequency of spraying required for control.

The short-stemmed (e.g. Cox's Orange Pippin, Sturmer Pippin) and late season apple varieties have the greatest risk of infestation by leafrollers. Short stems and large fruit bunches create well protected feeding niches for leafroller caterpillars. Careful pruning and thinning can help to achieve good spray penetration of the trees and the fruit clusters, as well as reducing the number of feeding niches, particularly on the short-stemmed varieties. Mummified fruits are used by leafrollers for overwintering and their removal can help to reduce overwintering populations.
