Since 1945, the European red mite, Metatetranychus ulmi (Koch) [=Paratetranychus pilosus (C. & F.)], has been one of the major pests in apple orchards in southwestern Quebec. Though it had been noted by Petch on fruit trees at Ville LaSalle, Que., in 1930 and at Lac Mégantic, Que., in 1931 it was not reported as causing serious injury to apple trees before July of 1945, when Beaulieu (1948) reported that it was responsible for the first important damage in a few orchards at Rougemont, Que. By 1946, infestations were general in the apple growing areas of southwestern Quebec and occurred as far east as the Quebec City district.

A number of predacious mites of the PHYTOSEIINAE (family LAELAPTIDAE), found in south-eastern England, mostly in association with fruit trees, are listed. Certain measurements and other characters that are of value in separating species are given. The species found were: Typhlodromus tiliae Oudm., T. cucumeris Oudm., T. tiliarum Oudm., T. rhenanus (Oudm.), T. finlandicus (Oudm.), T. umbraticus Chant, T. massei Nesbitt, T. vitis Oudm., T. soleiger (Ribaga), Phytoseius macropilis (Banks) and two Amblyseius spp. Of these, T. tiliae, T. finlandicus and P. macropilis are normally abundant on apple trees, but only T. tiliae remains abundant on commercially-grown apple trees. For each species a list of plants on which it has been found is given.Details of the life-history of laboratory-reared mites are given and these, together with counts of field populations, show that three generations a year is normal.Predacious phytoseiine mites feed on several species of TETRANYCHIDAE, including Metatetranychus ulmi (Koch) and Tetranychus telarius (L.); when M. ulmi is supplied in adequate numbers, adults of T. tiliae consume 3 mites per day, the nymphs 2 mites per day, on an average. It is thought that they also feed on plant tissue, since individuals survived in the laboratory for a considerable length of time in the absence of phytophagous mites, though eggs were not laid.

Methods Of Control

Various species of Curculionidae are injurious to orchards in Ukraine, but Sciaphobus squalidus, Gyll. (fig. 1) is considered by fruit-growers to be the most harmful, as it attacks the buds of all fruit trees. Mr. Znamenskii was the first to make an adequate study of the life-history of this insect. The following notes give an account of my own observations and deal principally with methods of control.

The predaceous mirid Deraeocoris nebulosus (Uhler) is found on more than 50 species of ornamental trees and shrubs where it feeds on several important pest species (Wheeler et al. 1975). It is a common mite and aphid predator in commercial apple orchards in Virginia (Parrella et al. 1978). Wheeler et al. (1975) described the nymphal stages and biology, but made no mention of the egg or oviposition site. We describe the egg and oviposition site which we discovered while studying various predators of the European red mite, Panonychus ulmi (Koch), in Virginia apple orchards. Eggs and oviposition sites of other predaceous mirids associated with apple have been described (Kullenberg 1942; Collyer 1952, 1953; Sanford 1964; Horsburgh and Asquith 1968, 1970).

For several years experiments on codling moth control have been carried on in a large old pear orchard near Beamsville in the Niagara Peninsula, Ontario. This orchard comprises about nine acres of several varieties but predominantly Bartlett, and has been established for about 80 years. It is more or less isolated from other large pear or apple orchards.

Terminology, food plants, dispersion and economic importance of the European red mite, Paratetranychus pilosus C. & F., which affects deciduous fruit trees in America, are discussed. The mite, first observed in Nova Scotia in 1913, became of economic importance in 1925. The life history, obtained from an insectary and field study extending over a period of three years from 1930 to 1932, is recorded in detail. There are two complete generations and three partial generations in Nova Scotia. Fluctuations in temperature markedly affect mite development. Natural control of the winter eggs is important.

In 1889 I received from the late William Brown, of Charlottetown, P. E. I., some larvæ of a small case-bearer, which he had found in large numbers upon his plum trees, and which also occurred in his pear and apple orchards. Since that time this insect has made itself well-known by its injuries in apple orchards in various localities in the Maritime Provinces, and in the Provinces of Quebec and Ontario. A beautifully illustrated and carefully prepared bulletin has been issued by Mr. M. V. Slingerland, of Cornell University Agricultural Experiment Station, in which the life history of this most interesting but very serious enemy of the fruit grower is fully described. The above illustration, kindly lent by the editor of the Canadian Horticulturist, is copied from that bulletin.

Among the important predators of the European red mite, Metatetranychus ulmi (Koch), in Nova Scotia is a group of predacious mites belonging to the subfamily Phytoseiinae. There is little information in the literature on the biology of the species in this subfamily. Smith and Summers (1949) reported on the bionomics of “Hypoaspis” macropilis (Banks), and Herbert (1952) and Ballard (1953) on the life-history of Typhlodromus fallacis (Garm.).

Lord (1949) listed the predators of the European red mite, Metatetranychus ulmi (Koch.), in Nova Scotia and described the effects of a number of chemicals on them. Among the more important predators is the thrips Haplothrips faurei Hood. This thrips, however, does not confine its feeding to European red mite eggs but readily attacks the eggs of many other mites and insects. There is strong evidence that it is one of the most important biotic factors in the natural control of insect and mite pests in Nova Scotia apple orchards. It and another species, Leptothrips mali (Fitch), are the only thrips of economic significance, and H. faurei, because of its greater numbers, is the more important. A description of the life-history of L. mali was given by Bailey (1940), who also (1939) studied the biology of another thrips, Scolothrips sexmaculatus (Perg.), which is of minor importance in Nova Scotia. The only other predacious thrips found is a species bclieved to be Zygothrips minutus Uzel, which occurs only rarely and in small numbers. Haplothrips subtilissimus Hal. (later identified as H. faurei), was found by Putman (1942) in Ontario to be predacious on phytophagons mites and the eggs of oriental fruit moth, Grapholitha molesta Busck.
