AbstractPterostichus melanarius Ill. was the predominant ground beetle recovered in pitfall traps in three blocks of apple trees at Jordan Station, Ont. In one block, C, the number of mature fifth-instar larvae of Cydia pomonella (L.) seeking overwintering sites was related significantly (r2 = 0.5476, P < 0.05) to the number of P. melanarius caught, but was not related significantly (r2 = 0.1181, P > 0.10) to the proportion of beetles that were serologically positive. The proportion of larvae pupating also was not related significantly (r2 = 0.2014, P > 0.10) to the number of P. melanarius. The total number of all predators caught was related significantly (r2 = 0.4490, P < 0.05) to the number of larvae present, but the proportion of larvae that pupated was not related significantly (r2 = 0.3606, P > 0.05) to the total number of predators.In block A, in 1983–1985, the number of mature larvae of C. pomonella seeking overwintering sites was not related significantly (r2 = 0.3763, 0.3619, and 0.5042, P > 0.05, respectively) to the number of P. melanarius taken in pitfall traps. In both blocks A and B, the number of serologically positive beetles was not related significantly (r2 = 0.3824 and 0.7921, P > 0.10, respectively) to the number of larvae seeking overwintering sites.Amara aenea DeG., Anisodactylus sanctaecrucis F., Bembidion quadrimaculatum oppositum Say, Clivinia impressifrons LeC., Diplochaeila impressicolis (Dej.), Harpalus aeneus F., and Pterostichus chalcites Say also gave positive serological reactions to the antiserum against C. pomonella.The occurrence of other species of Lepidoptera did not affect significantly the results obtained for C. pomonella.

A number of authors who have mentioned phytoseiid mites as predators of tetranychids reported that “Seius” or “Seiulus” spp. hibernated in the bark of trees, but until recently the taxonomy of the Phytoseiidae was so confused that the identity of the species concerned is uncertain. Herbert (1952), in Nova Scotia,was apparently the first to deal with species that can be definitely identified; she reported that a number of species of Typhlodromus, including most of those occurring on peach in Ontario, overwintered on apple trees under bark scales, in empty hibernacula of the eye-spotted bud moth, Spilonota ocellana (D. & S.), in empty oyster-shell scales, Lepidosaphes ulmi (L.), and in cocoons of the codling moth, Carpocapsa pomonella (L.). Chant (1958) found numbers of T. pyri Scheut. hibernating in burlap pads tied to apple trees in England.

Trials to determine the extent of fruit protection given by spraying spores of Bacillus cereus Frankland and Frankland on apple trees exposed to natural attack from the codling moth, Carpocapsa pomonella (L.), were carried out in the experimental apple orchard of the Entomology Laboratory at Summerland, British Columbia. Heavy injury was expected there on trees not receiving commercial insecticide applications. Ten test and ten check trees were chosen at random. Check trees received no treatment of any kind. Test trees were treated with six sprays between May 26 and June 29, 1954, and five between August 5 and September 8, 1954.

Predacious Species

It has been established that a complex of predacious arthropods on apple trees in Nova Scotia can control phytophagous mite populations (Lord, 1949). Some of the predators, when sufficiently numerous, may also be important in the control of other pests such as the eye-spotted bud-moth, Spilonota ocellana (D. & S.), and the codling moth, Carpocapsa pomonella (L.). When predation has reduced the mite population to small numbers, the insect predators almost disappear from the orchard. In most orchards in this province, the use of spray materials innocuous to predators has greatly reduced the phytophagous mite populations. The low mite population is an important gain but it is not known whether the attendant small numbers of predators is advantageous in the natural control of pests in general. This will be answered in time by the experience of the growers and, meanwhile, further research is needed on the interrelations of the phytophagous and predacious species and on how they are affected by orchard practices and other factors. This involves studies on the food preferences and behaviour of many species. In addition, means must be found to modify cultural practices to make conditions as favourable as possible for certain species of predators.

Several authors (Charmillot and Baggiolini 1975; Proverbs et al. 1975; Roelofs et al. 1976; MacLellan 1976) have stated that mass-trapping male codling moths with sex pheromones did not provide economic control of this pest. MacLellan (1976), however, reported suppression of codling moth populations in unsprayed orchards 2-3 ha in size and Madsen et al. (1976) obtained similar results in orchards in which sprays were not applied specifically for codling moth control. In 1975 and 1976 similar studies were undertaken in three 0.5–0.75 ha plots (A, B, C) of mature apple trees at Vineland (Hagley 1970). Plots A and B had not received insecticide sprays from 1969 to 1974 and had relatively high codling moth infestation levels (Table I). Plot C had been on a pest management program since 1971.
