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%).

Production Areas

Apple maggot (Rhagoletis pomonella) is an insect pest of apple (Malus domestica) that is currently limited in extent in the commercial production areas of Washington State thanks to a quarantine program. We estimate the costs to the Washington economy if this pest were to spread more widely. Apple maggot control costs are related to the pressure of codling moth (Cydia pomonella), the most prevalent insect pest in commercial apple production in Washington State. It was found that the losses for the Washington apple industry’s range from $510 million to $557 million, depending on the codling moth pressure. Our findings underscore the importance of an efficient quarantine program that minimized the risk of spreading the pest along with additional costs associated with quarantined areas.

AbstractWild codling moth, Cydia pomonella (L.), females were trapped from May through September in the upper (Yakima) and lower (White Swan) Yakima River Basin, WA, using 10 bait traps and 4 and 19 blacklight traps, respectively, for 2 and 5 years in abandoned apple orchards. The average spermatophore count per female at Yakima was 1.08; at White Swan it was 1.76. The spermatophore count was similar in both first (0.97 and 1.79) and second (1.00 and 1.70) generations at both locations. Regression analysis of field data and laboratory tests showed that cool temperatures reduced the number of spermatophores, which reflect reduced mating. There was a high correlation between the number of small spermatophores and females with multiple spermatophores. Usually females with a large spermatophore mated only once. Females usually mated on the 1st day following emergence. Once mated, even females with small spermatophores seldom mated again on subsequent days.

Monitoring of Codling Moth (Cydia Pomonella L.) in Apple Orchards Using Two MethodsThe present studies were conducted in 1999-2001 in three apple orchards differing from each other by the system of cultivation, the type of agricultural treatments and chemical control of pests. Their purpose was to monitor codling moth (Cydia pomonellaL.) in different types of apple orchards using pheromone traps, finding out the relation between the occurrence of moths and the sum of effective temperatures as well as determining the number of wintering caterpillars of this species with the use of bands of corrugated paper. The analysis of male flight of codling moth on the basis of pheromone traps makes it possible to state the occurrence of two generations in each studied year. The maximum population of the first generation was observed in the second or third ten days of June, while that of the second generation in the first ten days of August. The moths flight began when the sum of effective temperatures was 109.2-145.2°C, and the mean diurnal temperature was 12.3-17.2°C.

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
