Abstract

BactoSpeine DF (54% Bacillus thuringiensis subsp. kurstaki), Mospilan 20 SG (20% acetamiprid), Konflic (50% Quassia amara extract + 50% potassium salts of fatty acids), and Laser 240 SC (240 g/1 spinosad). The experiment took place over 32 days, during which the average temperature in the test site was 24.1°C, relative humidity 81.6%, and maximum light of 250 lux, 15:9 (L: Attack intensity ranged from 8.0 ± 1.9 galleries/ST (mean ± standard deviation) (in spinosad) to 18.7 ± 1.1 galleries/ST (in control), and significant differences were recorded still only between acetamiprid and spinosad on the one hand, and the other variants, on the other hand. Because some females died or left the galleries after entering the wood, the number of females with offspring per ST (FDST) was slightly lower than the intensity of the infestation. BactoSpeine DF (Valent BioSciences LLC, USA; lot nr. 305055PG30, data fabricaţiei 09.2019) este un produs biologic pe bază de Bacillus thuringiensis subspecia kurstaki (Btk), cu acţiune prin ingestie.
