Properties and stability Malathion has good contact, stomach toxicity and certain fumigation, and has no internal absorption. After entering the insect body, it is oxidized to Malaxic phosphorus, which can play a more toxic role, but when entering warm-blood animals, it is hydrolyzed by Carbolesterase, which is not found in insects, so it loses its toxicity. Malathion has low toxicity and short residual period, and is effective for both prickly mouthpiece and masticatory mouthpiece pests.
