Methods. Trials were conducted in farms of the Steppe (Zaporizhia, Dnipro, Kherson, Mykolaiv regions) and the Forest-Steppe zone of Ukraine (Chernivtsi, Vinnytsia, Cherkasy, Poltava, Kyiv regions). Detailed examinations of trees (spring, summer and autumn period) were carried out to determine the pests species presence, it number, infestation area, and in particular apple blister mite. The Laboratory studies of pest biology were carried out under the conditions of educational production department of Uman National University of Horticulture. For that purposes were used an entomological gardens, where were located cups with water and apple shoots, Hani Crisp variety. It shoots were cut in the industrial garden in the phase of «End of leaf bud swelling» (BBCH 03). A field method, in the commercial apple orchards. A type of apple variety trees was Hani Crisp. Planting scheme — 4.0 × 3.0 m. Year of planting — 1992. Crown shape — sparsely (improved) — tiered. Rootstock — MM-106. Phases of plant development at application timing — «More leaves unfolded, not yet at full size» (BBCH 15) — «Pink bud stage» (BBCH 57) and «Flowers fading «(BBCH 69). Soil — shallow, low — humus dusty — loamy podzolic leached black soils: humus content — 1.3—2.5%; pH 4.8 — 5.2; mobile compounds Р2О5 — 130—180 mg/kg and К2О — 8.9—9.2 mg/kg (by Chirikov method). The measures for care of the experimental site — loosening a soil in the stem strips during the growing period, an application of organic and mineral fertilizers, a pruning, a splaying of grass between the rows (row spacing),a protection from pests and diseases. The technical effectiveness of applications was determined in different rates against Apple blister mite and it impact on yields in commercial apple orchards. Calculations were made according to generally accepted methods in in horticulture, plant protection and entomology. Results. It was established that the apple blister mite, which overwinters behind the scales of buds, begins it migration in spring at a midday air temperature above 10°C, massively infesting young leaves of trees in phases at application timing — «More leaves unfolded, not yet at full size «(BBCH 15) — «Pink bud stage» (BBCH 57), where it feeds up to 15 days, and afterthat in the formed gales during 18—23 days. It develops in two generations during the growing season The application of insecticides Sivanto Prime 200 SL (flupiradifuran, 200 g/l), Danadim Stable, EC (dimethoat, 400 g/l), Oberon Rapid 240 SC, (spiromezifen, 228,6 g/l + abemektin, 11.4 g/l), Fufanon 570, EC (malathion, 570 g/l) and Aktofit, EC (aversektin С, 0.2%) on a reduction of this species number of 72.9—93.3%. It allowed to obtain a high — grade apple product with a yield of 1.1—1.2 times higher comparing to control. The outcome of non-standard products did not exceed 11.7% compare to 18.3% in the control (water treatment). An application of these insecticides allowed to increase the effectiveness of main biometric indicators of trees, namely: the average length of annual shoots, shoot thickness, leaf surface area by 2.2—20.0%, 2.4—16.7% 1.02 times and 4.6—45.9%, accordingly, which is important for settlement of potential fruit buds and future yields. An analyze outcome of fruits biochemical analysis indicates about the feasibility of using these insecticides: versus to the control variant (water treatment) there is a higher percentage of solids content 0.8—2.3%, sugar — by 0.7—2.9%, tittric acids — by 1.8—3.5%, pectin substances — by 12.5%, and ascorbic acid — by 0.8—1.6%. Conclusions. Apple blister mite overwinters behind the scales of buds and begins it migration in spring at a midday air temperature above 10°C, massively infesting young leaves of trees in phases at application timing — «More leaves unfolded, not yet at full size «(BBCH 15), «Pink bud stage» (BBCH 57), where it feeds up to 15 days, and afterthat in the formed gales during 18—23 days.

Goal. To clarify the biological features of pearleaf blister mite (Eriophyes pyri Pgst.) and investigate the effectiveness of such preparations as: Sivanto Prime 200 SL, PK (flupyradifurone, 200 g/l), Danadim stable, KE (dimethoate, 400 g/l), Oberon Rapid 240 SC, KS (spiromesifen, 228.6 g/l + abamectin, 11.4 g/l), Fufanon 570, KE (malathion, 570 g/l) and Aktofit, KE (aversectin C, 0.2%), reduce the number and harmfulness of this phytophagan, its impact on the productivity of pears in industrial plantations. Methods. To determine the colonization of pear plantations by mites in horticultural farms of Ukraine, route surveys were carried out in the industrial pear plantations of Yablunivska variety. The planting scheme was 0.8 × 3.5 m. The planting year was 2014. The crown shape was thinned (improved) and story. The rootstock was a quince tree A. Stages of plant development at the time of treatment were «bursting buds (green cone)» (BBCH 10), «white buds» (BBCH 55), «end of flowering» (BBCH 69) and «fruit development» BBCH 75). The technical effectiveness of pesticides at different application rates was determined. The accounts were performed according to generally accepted methods in horticulture, plant protection and entomology. Results. Female pear leaf blister mite overwinter under the upper scales of the buds. In spring, at an average daily temperature above 10°C, they begin to feed with the juice of young leaves, covering them with galls, and lay eggs («bud bursting (green cone)» — «white bud») stages. The development of the first generation ends at the end of «flowering». Females of the second generation appear in late June, the third generation — in the first half of July. After rebirth, they leave galls and populate the buds for wintering (mid-late June to late Julyearly August). During the growing season the phytophagan develops in three generations. The use of Danadim stable, KE, Fufanon 570, KE, Sivanto Prime 200 SL, PK, Oberon Rapid 240 SC and Aktofit, KE provided a reduction in the number of this species by 75.3—93.9%, allowed to increase the effectiveness of basic biometric and biochemical indices of plantations, to obtain high-quality products with a yield of 1.1—1.5 times higher comparing with the control. Conclusions. During the growing season, the pear gall mite develops in three generations. Taking into account the peculiarities of the biology of pears and mites in the spring, the peculiarities of the mechanism of action of drugs against this species and other phytophages (leafeating, stem, sucking, including against the brown-marble bug) are most advisable to apply: in the phase of «bud break (green cone)» — Danadim stable, EC (2.0 l/ ha); in the «white bud» phase — Fufanon 570, EC (2.0 l/ha); after the «end of flowering» — Danadim stable, EC (2.0 l/ha). In summer (against the second and third generations of the pest), Sivanto Prime 200 SL, RK (0.75—1.0 l/ha), Oberon Rapid 240 SC, KS (0.6—0.8 l/ha), Aktofit, EC (6.0 l/ha) taking into account the duration of their action.
