Lightbrown apple moth		Greenheaded leafrollers		Brownheaded leafrollers
	Leafroller monitoring in IFP : Other factors

(1) Pheromone traps catch male moths which emerge ahead of females, mating, egg laying and caterpillar damage. This time lag allows control actions to be taken in the following one to two weeks.
(2) The time to start trapping is just before the application of the first highly-recommended leafroller spray in each region. This is petal fall or early November from Nelson northwards but is delayed to late November or early December in the south.
(3) While trapping only for lightbrown apple moth is acceptable in many localities, the greenheaded and brownheaded leafrollers can be locally important in some orchards of Otago, Canterbury, and Hawkes Bay. It is important to trap for these species at these locations and add trap catches together when determining if the spray threshold has been reached.
(4) Insecticide sprays should never be applied less than three weeks apart. The timing of spraying for leafrollers must be integrated with the control of other insects. When the spray threshold for leafrollers is exceeded, there is sufficient response time for timing sprays in relation to this and other pests. For integration with codling moth control, Mimic®, Alsystin® or Match® are the recommended sprays in IFP.
(5) Where mating disruption is being used for resistance management of a particular leafroller species, pheromone traps for that species can be used to check that mating disruption is working (i.e. no trap catches). This is because the high concentration of pheromone in the orchard should be preventing males for locating both calling female moths and the pheromone traps.
