The effects of peach leaf extracts (1%) from different varieties of peach trees in killing mosquito larvae are basically the same, and can kill more than 95% of mosquito larvae within 24 hours; low concentration (0.25-0.5%) extracts have no significant effect; fresh leaves and dried leaves have similar therapeutic effects, and are effective against mosquitoes and butterflies such as Culex pipiens, Anopheles sinensis, and Armigera infestans. Experiments have shown that peach leaves can replace chloroform or other anesthetics to kill Anopheles mosquitoes; young leaves are better than old leaves, fresh leaves are better than stale leaves, and crushed leaves are better than soaked. Because peach leaves contain glycosides, they can release hydrogen cyanide through the action of enzymes when crushed.
