“…The research showed that this biocontrol agent is efficient in controlling leaf blister mites in orchards. Moreover, T. pyri is able to survive and reproduce on the alternative food sources like fungi, pollen or plant juices, so the treatment with this mite is not necessary to be so often repeated [13].…”

Orchards constitute a place to live for different pests. Leaf blister mites belong to the family of eriophyoid mites and they can have significant economic meaning in fruit production. These are not free-living organisms and the majority of life they spend sheltered in blisters or under the bud scales, where they overwinter. In spring overwintered females leave the swelling buds and start to feed. In result of their feeding appear small blistered galls inside which females lay eggs. When the trees are numerously infested by leaf blister mites both efficiency of photosyntesis and vigor are significantly reduced, what directly influences on the yield of fruit. These pests can be effectively controlled only in such moments when they appear on the surface on plants, so it is particulary necessary to follow the deadlines in case of control leaf blister mites.

“…The predatory mite Typhlodromus pyri Scheuten, 1857 represents one of the most important biocontrol agents of phytophagous mites occurring in orchards and vineyards in many countries of Europe and North America (Helle & Sabelis 1985;Zacharda 1989;Mc-Murtry 1992;Schausberger 1999;Sengonca et al 2003;Duso 1989;Duso et al 2003;Sekrecka & Niemczyk 2006;Praslička et al 2011). Van de Vrie (1964) found that the populations of T. pyri in their growing season are wide-spread during the whole summer.…”

The adoption of the European Green Deal will limit acaricide use in high value crops like raspberry, to be replaced by biological control and other alternative strategies. More basic knowledge on mites in such crops is then necessary, like species, density, and their role as vectors of plant diseases. This study had four aims, focusing on raspberry leaves at northern altitude: (1) identify mite species; (2) study mite population densities; (3) investigate mite intra-plant distribution; (4) investigate co-occurrence of phytophagous mites, raspberry leaf blotch disorder and raspberry leaf blotch virus (RLBV). Four sites in south-eastern Norway were sampled five times. Floricanes from different parts of the sites were collected, taking one leaf from each of the upper, middle, and bottom zones of the cane. Mites were extracted with a washing technique and processed for species identification and RLBV detection. Mites and leaves were tested for RLBV by reverse transcription polymerase chain reaction (RT-PCR) with virus-specific primers. Phytophagous mites, Phyllocoptes gracilis, Tetranychus urticae, and Neotetranychus rubi, and predatory mites, Anystis baccarum and Typhlodromus (Typhlodromus) pyri were identified. All phytophagous mites in cultivated raspberry preferred the upper zone of floricanes, while in non-cultivated raspberry, they preferred the middle zone. The presence of phytophagous mites did not lead to raspberry leaf blotch disorder during this study. RLBV was detected in 1.3% of the sampled plants, none of them with leaf blotch symptoms, and in 4.3% of P. gracilis samples, and in some spider mite samples, implying that Tetranychids could also be vectors of RLBV.

Abstract: The intensity of symptoms on infested leaves was also different depending on treatments and years. The average biological activity was 82.4% in plots receiving releases of T. pyri and 58.8% in plots treated with Polysulphide-Ca.
