4.4.2. Dynamics of activity imago gadflies of sort Gasterophilus depending on summer weather conditions

For two years (2000-2001гг.) observations over summer imago gastric gadflies, it is close free vypasajushchihsja horses of various age and fatness, we collect the data confirming dependence of intensity of summer of gadflies from an ambient temperature and a solar insolation.

The data obtained by us are displayed in table 18.

The analysis of data of table 18 shows, that at srednednevnoj to temperature from 18 ° With to 20 ° With for two years of observations we register 22 days of high activity of females of gastric gadflies (at the account of five and more females near to a control horse for 30 minutes of observations), at temperature from 21 ° With to 25 With - 18 days, from 25 Si above - 4 days, at 92 days of summer imago gadflies on the average for a season.

On dropping of activity of summer imago gastric gadflies essential influence are rendered by weather conditions: dropping of temperature of air and light exposure, fogs and deposits.

By our observations it is noticed, that years imago gadflies of sort Gaslerophilus it was observed in a temperature regimen of air from 15 ° With to 30 ° With at a solar insolation from 25 thousand lk. To 100 thousand lux.

At reduction or augmentation of the given parametres of years stopped. Such indicators, as rate of a wind, relative humidity in attention not

Undertook. Therefore dynamics of activity of summer of gastric gadflies (fig. 4 and 5) graphically represents a curve having to 8-9 peaks of high activity during a season. The beginning of high activity imago gadflies during a season 2000г. It is noted since June, 31st, during a season 2001г. - since July, 10th. Recession of high activity of summer imago was registered these years since August, 25th and 23 accordingly.

Thus in the first case it was observed 9 and in the second - 8 peaks of high activity of summer imago gastric gadflies and their quantitative augmentation it is necessary for July and for the first decade аніуста, as defines calendar terms of planning and carrying out of preventive and medical actions.

It is necessary to notice, that is immediate in territory Novi chih iiskogo district of Altay territory duration of a season of summer imago gadflies of sort Gaslerophilus fell I - to II decades of June up to II - III decades of September.

4.4.2.1. Duration of time parazitirovanija and localisations of larvas of gastric gadflies to an organism of the owner

Knowledge of places of localisation of larvas and their time of a finding in an organism of the owner important for planning and carrying out of actions for struggle with gasterofilezom horses. The account of localisation and terms parazitirovanija larvas was conducted at parasitologic openings killed on meat-packing plants and openings of the fallen animals.

In references data about terms parazitirovanija larvas in an organism of the owner the various. So, M.A.Sultanov (1953) and N.A.Chereshnev (1954) hold the opinion, that the larva lives in an organism of the owner of 10-11 months, and on N.H.Enileevoj (1970) and A.A.Israilovu (1991) larvas of gastric gadflies of horses are registered within a year. At parasitologic openings of a gastroenteric tract at 146 horses we collect 46508 larvas II and SH age. The location of larvas, concrete date was thus considered and the specific accessory was defined. Data are presented in table 19. According to data of our researches (tab. 19) of a horse to the extremity of July in territory of Altay territory
