Sterile Insect Release

AbstractCodling moth, Cydia pomonella (L.), control by sterile insect release (SIR) was assessed in 320–526 ha of apples and pears in the Similkameen Valley, B.C., from 1976 to 1978. In preparation for SIR, the moth population was first reduced to low numbers by removal of neglected trees in 1972 and by chemical sprays in 1975. Sterile (35 krad) male and female moths were released in each orchard 2 or 3 times weekly from 1 May until early September. A total of 23,600 sterile moths/ha was released in 1976, 36,500 in 1977, and 31,800 in 1978. Populations of sterile (marked) and wild moths were monitored by sex pheromone traps, and damage was assessed by fruit examination at harvest. Control was very good except for a few orchards in which overwintered populations were too high to achieve adequate overflooding with sterile moths. Damage exceeded the economic threshold (0.5%) in only 1 of 86 treated orchards in 1976, in 6 of 193 orchards in 1977, and in 0 of 157 orchards in 1978. Results in 32 orchards showed that when wild populations are brought close to extinction all codling moth control measures can be omitted for 2 or more years depending on degree of orchard isolation. Omission of codling moth sprays from 1976 to 1978 did not result in any important change in population levels of other apple pests. Cost of control by SIR was ca. $225/ha per year vs. ca. $95 for chemical control.

Abstract The codling moth, Cydia pomonella (L.), is the key pest of apple production worldwide. In Morocco, there is a sustainable presence of codling moth causing considerable damage in apple orchards despite frequent applications of broad spectrum insecticides. For 12 years, sexual trapping and chemical control were performed and the development of the codling moth population was analysed in an orchard which was in the region of Azrou. The efficacy of some insecticides (azinphos-methyl, chlorpyriphos-ethyl, diflubenzuron, thiacloprid, methoxyfenozide, spinosad, and deltamethrin) was also evaluated on neonate larvae and compared with a laboratory sensitive strain. This procedure was done to assess an eventual resistance in Moroccan populations. The action threshold was usually exceeded, leading to an intensive chemical control, with an average frequency of 9 to 13 days. The chemical control was done according to the action persistence time of the insecticides and the trap captures. However, those two parameters are compromised in Moroccan conditions because of the high summer temperatures which disrupt the action of insecticides and exacerbate populations. The pheromone traps may become ineffective and useless. Neonate larvae were resistant to five insecticides out of seven. Such results suggest the presence of a cross resistance in local strains. Overall, the insect resistance, the functioning of the sexual traps, and some insecticides properties (persistence action, pre-harvest interval) are the key factors that could explain the failure to control these moths under Moroccan conditions.

AbstractThe intensive use of sex pheromone traps in an insecticide-free apple orchard from 1972 to 1974 reduced the codling moth population and level of fruit damage. The sex ratio of bait-trapped adults indicated that the male population was being reduced by the pheromone traps. In commercial orchards pheromone trapping of males suppressed codling moth damage to fruit but the amount of damage was above acceptable economic levels.

SummaryA prototype for pest development stages forecasting is developed in Kazakhstan exploiting data from the geoinformation technologies and using codling moth as a model pest in apples. The basic methodology involved operational thermal map retrieving based on MODIS land surface temperature products and weather stations data, their recalculation into accumulated degree days maps and then into maps of the phases of the codling moth population dynamics. The validation of the predicted dates of the development stages according to the in-situ data gathered in the apple orchards showed a good predictivity of the forecast maps. Predictivity of the prototype can be improved by using daily satellite sensor datasets and their calibration with data received from a network of weather stations installed in the orchards.

AbstractCodling moth populations on natural apple fruit trees scattered throughout Nova Scotia are compared with those in commercial orchards. In natural fruit, failure of crop, crop size, degree of isolation, amount of crowding by native trees, and natural enemies determine the level of codling moth numbers. Young commercial orchards require artificial control measures within a few years of first bearing fruit to prevent severe crop losses. In older commercial orchards natural controls require an occasional assist by chemical treatment to contain the codling moth below economically tolerable levels. Such treatment is applied to interfere as little as possible with known natural controls.

Codling moth although rare on New Zealand export pipfruit is a quarantine actionable pest that limits access to countries where it is not present and requires specific control measures during production Fumigation with phosphine gas is a disinfestation technology that has recently been extended to fresh produce Apples infested with codling moth fifth instar larvae and eggs were fumigated for two durations at concentrations from 500 to 3500 ppm phosphine at two temperatures Larval mortality assessed 3 days post fumigation at 05C increased with increasing dose with little difference between 48 and 72h treatments In contrast mortality after fumigation of larvae at 12C did not increase with dose and resulted in overall higher mortality than 05C Codling moth eggs were more susceptible to fumigation at 05C than at 12C; fumigation at 12C had minimal effect at all doses The implications for improved market access using phosphine fumigation are discussed

The codling moth, Cydia pomonella L., is a serious insect pest in pome fruit production worldwide with a preference for apple. The pest is known for having developed resistance to several chemical groups of insecticides, making its control difficult. The control and management of the codling moth is often hindered by a lack of understanding about its biology and ecology, including aspects of its population genetics. This review summarizes the information about the origin and biology of the codling moth, describes the mechanisms of resistance in this pest, and provides an overview of current research of resistant pest populations and genetic research both in Europe and globally. The main focus of this review is on non-pesticide control measures and anti-resistance strategies which help to reduce the number of chemical pesticides used and their residues on food and the local environment. Regular monitoring for insecticide resistance is essential for proactive management to mitigate potential insecticide resistance. Here we describe techniques for the detection of resistant variants and possibilities for monitoring resistance populations. Also, we present our present work on developing new methods to maintain effective control using appropriate integrated resistance management (IRM) strategies for this economically important perennial pest.

Abstract The series of experiments on codling moth (Cydia pomonella L.) control using mating disruption method were conducted in three experimental orchards during 2006-2010 growing seasons. The efficacy of two commercial pheromone preparations: Ecodian CP and Isomate CTT, in comparison to pesticides Calypso 480 SC and Appeal 04 PA, was evaluated on the base of percentage of damaged fruits, number of caterpillars collected during their migration for overwintering in bands of corrugated cardboard placed on tree trunk and number of moths caught in pheromone traps. Two thousands dispensers of Ecodian CP were used twice a season (at 6-week interval) on the area of 1 ha of the orchard. Five hundred of Isomate CTT dispensers were applied once a season on 1 ha of the orchard. In all the experiments, application of mating disruption method significantly reduced the level of apple damage; the control efficacy (calculated according to Abbott’s formula) ranged from 54.2% to 95.8%. The efficacy of chemical control ranged from 58.5% to 93.0%. The lower efficacy of mating disruption method was noticed in orchards with high codling moth population. The treatments also affected the number of caterpillars caught in bands of corrugated cardboard placed on tree trunk. In experiments where the codling moth was not controlled, the number of caterpillars per a band varied from 0.2 to 11.9 whereas in these where the pest was controlled chemically or by mating disruption method, their number varied from 1.4 to 2.8 specimens.
