| description | Seed production of cabbage in recent years is achieved via primarily by nonstop technology. However, the production of cabbage seeds in the Southern regions is associated with certain problems, in particular, the malicious activity of phytophages, are able in the years of outbreaks completely destroy the crop. One of the most dangerous species of today are baridi. Development a strategy for the protection of cabbage seed shoots is important the knowledge of species composition and bioecological peculiarities of development of the pathogen. Complex biology (the focus of unwanted phases in the underground part of the stump), the lack of registered insecticides and distribution of certain phenological phases of development of seed cabbage (flowering) makes it almost impossible to limit its population. For localisation of the pest in the adult stage requires knowledge of species composition and phenology of development in a particular ecological zone. Long-term studies were conducted on the species identification of the community of Baris in Dagestan. Identified 22 species, among which the most popular were bared turnip: Baris coerulescens Scop. (71.6% of the total population), subdominant - timida V. Rossi (6.1%), all other types were found in approximately equal quantities. On the basis of the drawings and the corresponding biometric measurements were supplemented with the morphological description of the most common type of Baris coerulescens Scop. By measuring the head capsule width was determined to be 4 larval age. The dependence of mass outbreaks of Baris coerulescens Scop of the figure hydrothermal coefficient. The implementation of the mass distribution of the phytophage takes place 2 years after seasons at hydrothermal coefficient = 0.5. When a relative measure of hydrothermal coefficient was ≥ 1,the density of the pest does not exceed a threshold. |
