Toxicity of Same Plant-Based Essential Oils Against American Cockroaches (Periplaneta americana L.) Adults

Influence of sanitary conditions on the field performance of chlorpyrifos-based baits against American cockroaches, Periplaneta americana (L.) (Dictyoptera: Blattidae).

The role of sanitation in performance of insecticidal bait stations containing 0.5% chlorpyrifos against the American cockroach, Periplaneta americana (L.), was investigated in residential premises.
