Pitfall trapping was used to assess the effect of a low-spray mating disruption program targeted against the codling moth and leafrollers on carabid communities (potential predators of codling moth, Cydia pomonella [L.], leafrollers [Lepidoptera: Tortricidae] and apple maggot, Rhagoletis pomonella [Walsh]) in the orchard ground cover. Abundance and species richness of carabids were generally higher in mating disruption blocks relative to conventionally-managed blocks. Over 2 yrs, 3,173 carabids representing 62 species in 27 genera were collected. The most common carabids (more than 5% of the total carabid population) were Harpalus pensylvanicus (DeGeer) (38.2%), Harpalus erythropus Dejean (11.4%), Poecilus lucublandus (Say) (10.1%), Dicaelus elongatus Bonelli (6.2%) and Harpalus longicollis LeConte (5.9%).

Insecticide Sprays

New Zealand apple growers need to produce crops that satisfy conflicting export market requirements Some markets want pestfree fruit while others demand residuefree fruit Pheromone mating disruption combined with the judicious use of insecticides enables crops to meet both demands This study in 14 Hawkes Bay apple orchards showed that seasonal pheromone trap catch was reduced by 70 from 401 codling moths/trap in the season before mating disruption was introduced to 117 moths/trap over the subsequent five seasons In the same period insecticide use reduced from 59 applications/season in 2006 07 to 23 in 200708 and 37 since 200809 The incidence of larvae in fruit where mating disruption operated averaged 001 which was lower than in orchards using insecticides only Damage increased from 200809 with greater reliance on codling moth granulosis virus over residual insecticides Nevertheless mating disruption with 34 insecticide sprays controlled codling moth to the high standard needed

Measures Of Effectiveness

Codling moth (Cydia pomonella) and leafrollers principally lightbrown apple moth (Epiphyas postvittana) are key pests of apples Pheromone mating disruption has until now required separate dispensers to be deployed for each pest group With 6001000 dispensers per ha for each species application costs are a significant factor limiting the wider adoption of multispecies mating disruption in New Zealand apple orchards The aim was to integrate the two disruption systems into a single dispenser and evaluate its performance against that of separate dispensers in paired block comparisons on four apple orchards The three measures of effectiveness pheromone trap catch suppression of moth mating and fruit damage at harvest all showed no statistical differences between the two treatments The performance of the new combination pheromone dispenser was equivalent to that when the two dispensers were deployed separately

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
