Sterile Male

AbstractSterile male codling moths, exposed as pupae to 40 krad of gamma radiation and released in an abandoned 20-tree apple orchard for 3 years, reduced the percentage of fruits injured by mature or almost mature second-brood larvae from 4.94 to 0.05. Numbers of sterile males released, ratios of sterile to fertile males during peak emergence of first-brood moths, and numbers of overwintering larvae were: 1961 (3 DDT sprays applied) — 0, 0:1, 400; 1962 — 21,300, 8:1, 957; 1963 — 67,500, 21:1, 43; 1964 — 89,200, 715:1, 6.

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.

Dominant Lethality

Chemicals must be used to control the codling moth, Carpocapsa pomonella (L.), in most apple and pear growing areas throughout the world. Unfortunately, this practice has caused or contributed to greatly increased mite populations, decimation of many beneficial insects, insecticide resistance, soil poisoning, and other problems. Successful use of the sterile male technique against the codling moth would eliminate or alleviate a number of these problems. This technique consists essentially in the sustained over-flooding of the native population with sexually sterile males. The main prerequisites for its use include: (1) a method of inducing sterility or dominant lethality in the sperm without affecting normal behaviour or longevity of the male, (2) the released insects themselves must not be injurious or noxious, ( 3 ) the method of release should permit intimate mingling of the sterile males with the native population, and (4) the availability of an economical method of mass culturing the insect. Photographs illustrate how these prerequisites were investigated for the codling moth.

AbstractAn artificial diet for rearing the codling moth is described. It is a modification of a casein–wheat germ diet that was initially developed for the cabbage looper. Agar was replaced by a mixture of wood sawdust, wheat flour, and wood pulp. Growth of microorganisms was controlled by sorbic acid and aureomycin, and by lowering the pH of the diet to 3.5 with citric acid. Production cost for dietary ingredients was about $1/1000 moths. The moths were slightly smaller than those reared on apple. When confined in cages, the sterilized diet-reared moths were somewhat less competitive than the apple-reared insects. However, sterilized diet-reared male moths released in an apple orchard dispersed more rapidly than sterilized apple-reared males.

In this paper is reported the evaluation of biological efficacy of two minor components that was added to the basic sex pheromone component Cydia pomonella L., E8, E10-C12-OH. The use of minor component- C.M.-1 of increasing concentrations in binary mixture compositions with the basic sex phe-romone component of codling moth on pheromone-impregnated rubber septa in delta pheromone traps has shown an increased effectiveness by 56-62% in field trials on apple orchard. At the same time, the number of males caught in delta pheromone traps where were used minor component - C.M.-2 in binary mixture compositions increased by 29-35%. Auxiliary research is still needed.

Dominant Lethality

Exposure of the mature pupa or the newly emerged adult of the codling moth, Carpocapsa pomonella (L.), to 40,000 rads of gamma radiation induced dominant lethality in at least 98% of the sperm without affecting adult emergence, mating behavior, or adult longevity. Higher dosages decreased the frequency of mating. Irradiation of eggs, mature larvae, or young pupae induced dominant lethality in a high percentage of the sperm, but caused prohibitively high mortality and frequently reduced mating. The female was more radiosensitive than the male. In general, sensitivity decreased as development progressed from the egg to the adult stage.

And Control

Reproduction and olfactory behavioral responses of codling moth, Cydia pomonella (L.), females to synthetic α-farnesene were observed in the laboratory as well as their reproduction behaviors in an apple orchard. Calling levels were lifted and ovipositional peaks were advanced in codling moth females at presence of 1μg and 0.1 μg of α-farnesene, respectively. Mated females of codling moth more actively responded to 0.01 μg α-farnesene with walking and wing-fanning while walking than to other doses (0.001, 0.1, 1, 10 μg ) and control. The results show that α-farnesene plays important roles in the behaviors of codling moth females. However, the differences between responses to α-farnesene and those to apple volatiles by codling moth females indicate that components other than α-farnesene in apple volatiles also have biological activities

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.

Mating Ability

This is the first of a series of papers dealing with investigations that were commenced in 1956 at Summerland, British Columbia, to determine if the codling moth, Carpocapsa pomonella (L.), could be eradicated in the interior of British Columbia by the release of sexually sterile male moths.One of the most important prerequisites for the success of this method is the development of a technique that will sterilize the male without seriously affecting its behaviour, particularly mating ability and longevity. Complete or almost complete sterility has been induced in one or both sexes of certain species of insects by feeding them chemicals (LaBrecque et al., 1960), or by exposing them to X- or gamma rays (Bushland and Hopkins, 1953), or by subjecting them to abnormally high temperatures (Riordan, 1957).
