AbstractApple orchard tests in 1974, 1975, and 1976 showed that applications of granulosis virus reduced deep-entry damage by larvae of the codling moth, Laspeyresia pomonella (L.), to apple fruit at harvest by 55 to 96% compared with damage to fruit on nontreated check trees. Sting or shallow-entry injury was usually higher on virus-sprayed trees than on check trees presumably because larvae were killed by the virus soon after entry into the apple.

AbstractCodling moth, Laspeyresia pomonella (L.), injury in a 14-ha apple orchard gradually increased in 1973 and 1974 despite the presence of 480 sex pheromone traps (1 mg trans-8, trans-10, dodecadien-1-ol per trap). Percentage injured fruit at harvest was 0.00075, 0.0062, and 0,033 in 1972, 1973, and 1974, respectively. Numbers of wild male moths trapped increased from 3e in 1973 to 64 in 1974.

AbstractBecause laboratory and field cage experiments had shown that partially sterile (25 krad dose) male codling moths were sexually more competitive than sterile (40 krad) ones, a study was made in a British Columbia orchard in 1970 to determine whether release of 25 krad moths of mixed sexes would suppress this pest more effectively than release of 40 krad moths. Approximately 75,000 moths/ha were released from 24 April to 25 September for each dose level. In the 25 krad moth release plot, the percentage of apple fruits damaged by this pest at harvest was reduced from 0.21 in 1969 to 0.08 in 1970, whereas in the 40 krad plot damage was reduced from 0.04 in 1969 to 0.02 in 1970.Release of 25 krad moths was also compared with insecticide sprays for codling moth suppression in two small areas at Cawston and Olalla, B.C. At Cawston, the percentage of apples damaged at harvest was reduced from 1.0 in 1969, after three sprays of phosalone, to 0.1 in 1970 after release of irradiated insects. In contrast, per cent damage in a nearby apple orchard, sprayed twice with azinphos-methyl in 1969 and 1970, increased from 2.0 in 1969 to 8.1 in 1970. At Olalla, per cent damage was about the same (0.5) in 1969, after three phosalone sprays, as in 1970 (0.6) after release of irradiated insects. In a neighboring apple orchard, sprayed twice with phosalone in 1969 and 1970, per cent damage was about the same (1.0–1.2) each year.

AbstractAll codling moth larvae, Laspeyresia pomonella (L.), in 100,000 infested apples were killed by fumigation with 32 g/m3 methyl bromide for 2 h at about 17 °C followed by 31–35 days of storage at −0.5 °C. The apples were harvested into bins, fumigated, and placed in a standard cold storage room of a grower’s packinghouse as would be done under commercial conditions. Standard cold storage killed all first and second, and some third, instar larvae in nonfumigated fruit. Cursory sampling indicated that fumigation alone, without subsequent cold storage, could kill all stages. The fumigation and storage treatment did not injure Red Delicious, Golden Delicious, Spartan, Jonathan, or Newtown apples.

Successive Generations

SummaryThe codling moth, Cydia pomonella L., achieved four successive generations in Egyptian pear orchards in 1974. Indices of infested fruits showed four peaks of infestation; the first at the end of April, the second during the first week of June, the third during the first week of July and the last at the end of July.
