Abstract. The purpose of this study is the ascertainment of to the physiological responses to exogenous exposure to aqueous solutions of the drug “Violet-K” (C24H28N3 Cl) in the phase of wintering eggs of the local and introduced silkworm species. Methods. The research was carried out according to the methodology developed by us for the content, selection and processing of material [9], [10]. Statistical analysis was performed according to G. F. Lakin [11]. Results. It was found that in the absence of sharp fluctuations of the temperature and air humidity, the effect of exposure to water and 0.01 % and 0.001 % aqueous solutions of the “Violet-K” preparation on hibernating eggs causes a response of caterpillars at younger ages during molting, by the fifth age this effect diminishes. A strong response to the impact in terms of weight of caterpillars was revealed for the introduced silkworm species: against the background of minor fluctuations in the “Oragase” variant for caterpillars “Sverico-sari” the difference with the control by age is 16.4 % (III), 143.3 % (IV) and 27.3 % (V). The introduced species “Oragase” often differs from the “Sverico-sari” and the local breed “Veten” by the presence of negative responses: the weight of caterpillars after exposure compared to the control corresponds to + 43.7 % (III), + 65.0 % (IV), –36.2 % (V). It was found that the content of wintering grains in water and aqueous solutions of the “Violet-K” preparation leads to the weight increase of the silk shell: by 54.4–80.5 % (p < 0.05 and 0.001) in the local species, as well as by 11.4–16.1 % (0.001 %) and 2.7 % (0.01 % solution “Violet K”) p < 0.05 and 0.001. The species “Oragase” differs in this effect compared with the control, particularly, in the comparison with control, the impact promotes to a significant decrease in the weight of the silk shell by 33 % (–78.5 mg) and 22.5 % (–49.0 mg), p < 0.001. The impact is reflected in the date of departure of butterflies and the number of laid eggs, and only in introduced species: the positive effect compared to the control, on average on 1 female was 3.6–4.8 times higher (“Sverico-sari”) and 1.1 times (“Oragase”).
Keywords: the local breed “Veten”, introduced silkworm breeds “Sverico-sari”, “Oragase”, the physiological reaction, water, “Violet-K” (C24H28N3 Cl).
