[The activity of cyfluthrin and cypermethrin-based preparations against the vector of the causative agent of tick-borne relapsing fever].

Laboratory tests have established a high activity and long-term persistence of some cipermethrin isomers (fendone, fastac) and cifluthrin (zolfac) against the tick Ornithodoros papillipes, a carrier of tick-borne relapsing fever. These indices are considerably superior to those of an isomer mixture of cipermethrin (cimbush, ripkord). This can be applied to deltamethrin and cigalothrin.

[The insecticidal activity of thermal aerosols of permethrin].

The aerosols derived from the designed 2% permethrine-containing pyrotechnical formulations (tablets and briquets) were tested for their effects in laboratory and field conditions. When tested in the chamber, its LC50 and LC99 were 0.056 and 0.

[The acaricidal activity of pyrethroids against Ixodes persulcatus P. Sch. nymphs].

The efficiency of 9 drugs based on cipermethrin, deltamethrin, permethrin, lambdacigalothrin, ciphenothrin, phenothrin against hungry I. persulcatus nymphs was studied in the laboratory setting. The values LD50 and LD99 (in g of an active ingredient per m2) were found when the nymphs got into contacts with the treated filter paper for 10 sec and 1 min.

[The insecticidal activity of the preparation K-othrin in relation to different species of arthropods].

A high insecticidal activity of K-otrin (flow), a preparation containing 2.5% of deltametrin, towards various arthropods, was revealed in laboratory experiments and in field trials. The effective doses were determined: 0.

[The efficacy of the biological insecticide BLP with regard to the larvae of blood-sucking mosquitoes in Uzbekistan].

The efficacy of a biologic larvicidal preparation BLP was under study; the insecticide was prepared on the basis of a new strain of B. thuringiensis var. israilensis H-14, isolated from natural material, and its activity to Ae.

[The efficacy of a new insecticide ethofenprox (Trebon) for controlling different types of insects].

The insecticidal action of the new compound ethofenprox (trebon) in the form of 10 and 30% flow concentrate against house flies, cockroaches, bed bugs, rat fleas, mosquito imagines and larvae of Aedes and Culex genera was studied in the laboratory and in the field. The effective doses and the methods of spraying were established. 10% flow trebon is allowed by the USSR Ministry of Health to be useful in medical disinfection.

[The fauna and ecological traits of the dominant species of blood-sucking mosquitoes on the area of irrigated lands in Uzbekistan].

Blood-sucking mosquito fauna, season and circadian activity of predominant species, dynamics of hatching place formation in the villages and on the territories surrounding the Golodnaya and Dzhizakskaya steppes have been studied for many years and the materials have been presented. The data obtained serve as the basis for planning, prophylactic and eliminating measures.

[Trials of the insecticides Icon and Ficam against mosquitoes in the southern USSR].

Two residual insecticides (Icon 10% WP, ICI and Ficam W 80% WP, CAMCO) were in 1989 tested in field trials in Tajikistan, Azerbaijan and Uzbekistan against Anopheles superpictus, An. sacharovi, An. pulcherrimus, An.

[Features of the intima of veins of the human vertebral canal].

The veins of the human vertebral canal have a complex internal structure that is stipulated with presence of a large amount of variable in form, size and position formations--plates, trabecules, complex and combined forms, parietal reticularity, cristae and valves. The data on peculiarities of macro-microconstruction of these structures, amount and their localization in various veins and parts of the vertebral canal are presented. Having analysed the data obtained, it is possible to divide the vertebral canal veins into three morphofunctional segments--superior (for the space of C1-C6), middle (C7-Th5) and inferior (Th6 and lower), possessing various hemodynamic characteristics Department of Human Anatomy, Medical Institute, Blagoveshchensk.
