I tracked down the work in Russian by Anna Zinovievna Brandorf, et al. 

Анна Зиновьевна Брандорф, Алексей Борисович Сохликов. ТРОПИЛЕЛАПСОЗ ПЧЕЛ – НОВАЯ УГРОЗА РОССИЙСКОМУ ПЧЕЛОВОДСТВУ. Российский журнал «Проблемы ветеринарной санитарии, гигиены и экологии» № 2 (46), 2023. ISSN 2075-1818

Anna Zinovievna Brandorf , Alexey Borisovich Sokhlikov. TROPILELAPSOSIS OF BEES – A NEW THREAT TO RUSSIAN BEEKEEPING. Russian journal “Problems of veterinary sanitation, hygiene and ecology” No. 2(46), 2023. ISSN 2075-1818

Detection and spread of bee tropilelapsosis in the territory of the Russian Federation causes concern for the beekeeping community. Previously, it was believed that a long broodless period in winter provides reliable protection against the spread of this mite. But now the situation is changing, the climate is warming. Many beekeepers keep bees of different breeds, some of them, for example Buckfast, begin raising brood very early and finish it late, which reduces the gap of brood in the nests of bees. In the southern regions, bee colonies do not have a broodless period; bee nests always contain brood of different ages. 

Regular, uncontrolled import of bee packages from countries where tropilelapsosis occurs will also cause damage to apiaries of the Russian Federation during the summer import period; during the broodless winter period, the mites may die, but if affected bees are imported the next year, tropilelapsosis will again appear throughout the summer period, which will lead to weakening of colonies, a decrease in their productivity and even death. The danger of invasion also lies in the fact that veterinary specialists and beekeepers have not encountered this disease before, have never seen the Tropilaelaps spp. mite, and cannot identify it.

It should be noted that during the entire period of research not a single Tropilaelaps mite was found on adult bees. In the autumn at 95% damage to the brood by Tropilaelaps, not a single mite was found on living worker bees.
