Tests for insecticidal activity
Eggs of Bombyx mori were kindly provided by employees of the National Scientific Center ”Institute of Experimental and Clinical Veterinary Medicine” (Kharkiv, Ukraine). Spore-forming samples obtained from fecal samples were tested for insecticidal activity againstBombyx mori andAedes mosquitoes. The Aedes larvae were withdrawn from the population maintained in the laboratory. The testing was conducted using the previously described methodology (Ahmed et al., 2017).
