Improving of monitoring of dynamics of quantity and structure of pea aphid (Acyrthosiphon pisum narris) population
Pea aphid population structure is an important parameter characterizing its state and stage of the dynamics development in the current season. In a year of depression females and preimago stage larvae are more than 45% that indicates suppression of female reproductive func-tion and a significant death of small instar larvae; in a year of mass pest development larvae prevail in the population, 1-instar larvae are more than 40% among them. Based on the results of 2000—2002 researches a method of the entomological net cutting does not fully depict a structure of the pea aphid population. In biological researches it is preferable to use a modified method of aphid number record — aphid shaking on cartoon plane-table with subsequent plant examination. Main factors influenced onto the dynamics of quantity and structure of pea aphid (Acyrthosiphon pisum harris) population are an air tem-perature and rainfall.

Radiological estimation of agrochemical practices of improvement of meadows contaminated by 137Cs and 90Sr as a result of the accident at Chernobyl NPP
At development of strategy of rehabilitation of basic types of the Belarus Polesye meadows contaminated as a result of the accident at Chernobyl NPP and at substantiation of application of the most effective practices of their improvement (protective counter-measures) it is necessary to use not only parameters of radio-ecological estimation (multiple of 137Cs and 90Sr concentration reduction in forages after intro-duction of counter-measures) but also it is necessary to take into account parameters of radiological estimation (value of the prevented collec-tive doze — man. Sv/year) and economic-radiological estimation (cost of decrease of unit of the prevented collective doze — thousand US $ per 1 man Sv in a year) as a result of application of protective actions. It has been established that application of agrotechnical and agrote-chemical protective actions at low-lying (waterlogged) meadows being peatbog soils during remote period after the accident at Chernobyl NPP (2000—2010) is more effective (cost of prevented collective doze < 5000$/man Sv) in comparison with water-meadows (12000—20000 $/man Sv) and waterless meadows at mineral soils (about 20000$/man Sv).

Medium for diluting of sperms of bulls
Lactose-yolk-glycerin medium is used for diluting of sperms of bulls in Government center for artificial insemination. It has developed for freezing of sperm in granules. Two-fractional environments are more effective at packing of sperm into culms. We have developed a medium on a base of citrate buffer and lactose. Sperm diluted with citrate-lactose-yolk-glycerin buffer and cooled in granules or culms had reduced percent-age of spermatozoids having damages in the micro- and macro-structure. Use of the sperm for insemination of cows promoted accumulation of greater quantity of spermatozoids in the top layers of horns of uterus and their survival. High level of fertilization has been obtained at insemina-tion of cows and heifers in farms.
