The insecticide susceptibility of Helopeltis theivora Waterhouse (Hemiptera: Miridae) is being evaluated using shoot and glass-vial assay as described by IRAC. However, the reliability depends on feeding preference contact toxicity. Hence, cocoa pod was used a substrate to test H. in comparison with existing methods. experimental results revealed that LC50 value all insecticides relatively lower bioassay than other two methods exhibited maximum mortality within 6 hr post-exposure. Among insecticides, fipronil most effective molecule followed lambda-cyhalothrin. theivora, which prefers feed due more tissue turgidity, thus facilitated adequate sap ingestion; whereas, these were limited bioassays. Therefore, it could be methodology determine against wide range molecules.
