Paperback. Condizione: New. Print on Demand. This book explores the results of multiple experiments conducted by the author to study the effectiveness of nicotine sulphate on the eggs and larvae of four different insect species: codling moths, silkworms, potato beetles, and tussock moths. The author discovered that the tested solutions containing nicotine sulphate were effective against the codling moth larvae and the fresh eggs of the silkworm moth, but not against the eggs of the other insects. The author also studied the exhalation of leaves sprayed with solutions of nicotine sulphate, and found that this exhalation was also harmful to the newly hatched insects. The book highlights the importance of understanding the effects of insecticides on different insect species, and provides valuable insights for farmers and researchers working in pest control and agriculture.
