[(ACARI: TROMBICULIDAE) (THE INFESTATION OF SMALL MAMMALS IN SOUTH-EASTERN VIETNAM WITH HARVEST MITES (ACARI: TROMBICULIDAE))].

This investigation was conducted in three provinces of southern Vietnam in September-October 2011. A total of 257 small mammals of 11 species were caught; among them 120 rodents were infected with harvest mites of 8 species (Trom- biculidac). About 4000 mites of nearly 1200 identified species were collected from the small mammals.

[INFECTION OF BLOOD-SUCKING MOSQUITOES (DIPTERA: CULICIDAE) WITH DIROFILARIAE (SPIRURIDA, ONCHOCERCIDAE) IN THE TULA REGION].

Blood-sucking mosquitoes (n = 2277) collected in Tula and its Region in 2013-2014 were examined using a PCR assay for dirofilariae. A total of 12 species from 4 genera (Culiseta, Aedes, Ochlerotatus [foreign character] Culex) out of 18 found mosquito species were infected with Dirofilaria immitis and D. repens.

[BLOODSUCKING MOSQUITOES (DIPTERA: CULICIDAE) IN, THE TULA REGION ARE POTENTIAL VECTORS OF DIROFILARIAS].

Bloodsucking mosquitoes were collected in Tula and its Region in May to August 2013-2014. The fauna included 17 species from 5 genera in the subfamily Culicinae and Anopheles maculipennis complex in the subsystem Anophelinae. Ochlerotatus cantans was a dominant species in the collections.

[PEDICULOSIS: CURRENT ASPECTS OF THE OLD PROBLEM].

Analysis of data on the incidence of pediculosis worldwide has shown that this disease still remains one of the major health problems in many countries. The ways of transmitting lice and different (social and biological) factors influencing lice infestation are considered. The country's real morbidity rate, such as the ratio of the number of reported pediculosis cases to the amount of pediculicides sold at drugstores in both Russia as a whole and its individual federal districts in particular, has been investigated.
