Interrelations of the common hamster (Cricetus cricetus) and Norway rat (Rattus norvegicus) in laboratory tests


Feoktistova N. Yu. , D. Sci., Kropotkina M. V., PhD., Kuznetsova E. V., Surov A.V., corr.-member of RAS Severtsov A. N., Institute of Ecology and Evolution, Russian Academy of Sciences, Leninsky 33 Moscow, 119071 Russia


Last half of the XX century the abundance of the common hamster dramatically declined across the whole range while in urban environment it began to increase. Many cities, which are actively colonized by hamsters, are occupied by Norway rats as well. However respondents from different cities noted that rats and hamsters never co-occur. It may be an effect of direct or indirect competition. For the first time in experimental tests we have shown that hamster urine odor causes the rise of corticosterone (stress hormone) level in rats. In direct contacts on neutral area in most cases rats demonstrated passivedefensive behavior and sat still in the corner. At the same time hamsters actively investigated the area, sniffed rats but showed no aggression. Urine odor of rats does not cause the rise of cortizol level in hamsters. We suppose that revealed behavioral and physiological responses of rats to hamster’s odor and presence could be one of the mechanisms of competitive exception.

The article presents the results of a retrospective analysis of the incidence of malaria by official registration in the Republic of Tajikistan (RT) for the period 1990-2017. Currently, the incidence of malaria in RT is in the phase of elimination of the malaria program. The peak of malaria was registered in 1997, when 29794 cases were registered, i.e. sick and parasitic carriers, which corresponded to the level of 333 per 100 thousand population. In the future, in connection with the organization of effective antimalarial and anti-mosquito control measures, it was possible to reduce the number of patients to 112 in 2010, to 1 in 2016. and up to 2 patients in 2017. At the same time, it should be noted that, as before, the problem of imported malaria is urgent for the republic.

New larvicide based on methoprene against mosquitoes


Kostina M. N., Bidevkiva M. V., Vinogradova A. I.


As a larvicide for the destruction of mosquito larvae in water bodies of various types (natural, urban), the drug «LODI LAVRАЕ CAPS» is proposed on the basis of metoprene (5%) – the analogue of the juvenile hormone (AUG). A high target efficiency for larvae Ae aegypti and the duration of the residual effect for 61 days (observation period) was established. Toxicological studies have shown safety for humans, warm-blooded animals and environmental objects.


Keywords: methoprene, juvenile hormone analogue, insect development regulators (PPH), mosquito larvae, larvicide, residual action, safe regimens

The methodical approaches to the determination of the main insecticidal substances in microcapsulated agents based on natural (lipids) and synthetic (polymers) capsule formers are considered. A possible option based on the method of GC (flame ionization detection) using trivial equipment of domestic production and capillary analytical column is proposed. The analysis in the selected chromatographic conditions as model solutions of insecticides, and specific microencapsulated products containing permethrin, cypermethrin (isomers), deltamethrin, lambdacyhalothrin and chlorpyrifos. The proposed conditions of chromatography make it possible to carry out screening studies of working solutions of microcapsulated preparations up to concentrations of 0.01–0.005% for the active substance for pyrethroid insecticides. We should also mention the possibility of a joint definition of microencapsulated in the media all the insecticidal substances, including those close in polarity to cypermethrin and lambdacyhalothrin, previously determined by HPLC method in total.
