Leafrollers are important pests of apples and infested fruit can result in rejection of export consignments Leafroller mating disruption using a pheromone blend with activity against three species was examined in 12 Hawkes Bay orchards over two seasons (200910 and 201011) Pheromone dispensers (600/ha) and a single insecticide were applied to trees in early November and subsequent insecticide use was based on leafroller pheromone trapping and thresholds The pheromone blend substantially suppressed mating of virgin female lightbrown apple moth in treated orchards and reduced male catch in pheromone traps by up to 98 compared with the season prior to implementation Insecticide use for leafroller control decreased accordingly from 2127 insecticides per block in 2008/09 to 1018 in 2010/11 Leafroller control using mating disruption was acceptable fruit damage varied from 03 to 016 and no leafroller larvae were found on fruit in both field assessments and phytosanitary inspections of packed cartons

Natural Dispersal

To assist the natural distribution of the leafroller parasitoid Trigonospila brevifacies to horticultural areas in the Nelson region 181 T brevifacies pupae and 329 adults were released in 1999 at four sites adjacent to apple orchards near Motueka Release material was supplied from fieldcollected parasitoids in Hawkes Bay and a laboratory colony held at the Mt Albert Research Centre in Auckland Successful establishment of the parasitoid was recorded at all four sites and at a nearby nonrelease site in 2000 In 2000 319 of fourth instar and older larvae were parasitised by T brevifacies while in 2001 parasitism was 1166 Important pest tortricid species including Epiphyas postvittana (Walker) (lightbrown apple moth) were among the hosts The successful establishment of T brevifacies in Nelson and its further natural dispersal will increase the potential for the reduction of economically important leafroller species by biocontrol agents

Leafroller larvae and pupae were collected during timed searches in January and April 2013 from host plants at six scrub vegetation sites in two Nelson horticultural districts approximately 40 km apart The numbers of leafrollers and parasitoid species recovered were similar in both districts Most of the leafroller larvae collected were Epiphyas postvittana (Walker) (lightbrown apple moth LBAM) and most of these were found on gorse and broom In total 293 larvae and 11 pupae were reared successfully with 39 parasitism A wide diversity of parasitoids was recovered comprising 10 species from five families with Dolichogenidea tasmanica (Braconidae) the most common (80) The diversity of parasitoids and parasitism of leafrollers in unmanaged environments outside orchards may help to reduce leafroller pressure and the risk of fruit infestation in surrounding commercial orchards
