Identification
Biological Activities
Psiadia penninervia has demonstrated significant insecticide activity during laboratory evaluations targeting the bean aphid, Aphis craccivora. Among the five medicinal plant extracts tested, this species exhibited the lowest lethal concentration (LC50) value against the aphids, indicating high potency. However, the study also revealed that the extract possesses a relatively low LC50 value for the predator Chrysoperla carnea, suggesting higher toxicity to beneficial insects compared to other tested plants. While the plant contains substantial flavonoid components, its impact on predatory species must be carefully considered in practical applications. Consequently, while it shows strong insecticidal potential, other species like Ochradenus baccatus may offer a safer profile for integrated pest management programs.
Compounds
Psiadia penninervia is a notable botanical species that contains significant amounts of flavonoids. Through HPLC analysis, researchers determined that this plant possesses a total flavonoid content of 869.4 mg/kg. These chemical components contribute to the plant's potential as a biological insecticide against pests like the bean aphid. While the extract is effective, its specific chemical makeup plays a crucial role in its overall toxicity and environmental impact. Understanding these flavonoid concentrations is essential for developing safer, plant-based alternatives to synthetic chemicals.
Conditions
Psiadia penninervia serves as an effective botanical insecticide against the bean aphid, Aphis craccivora. In laboratory evaluations, the methanolic extract of this plant demonstrated a high level of toxicity toward the pest. Specifically, it achieved the lowest lethal concentration (LC50) value of 128.546 µg/mL among all the tested plant species. This low concentration indicates that Psiadia penninervia is highly potent in treating Aphis craccivora infestations. Consequently, the plant's extract shows significant potential for managing these aphid populations.
Preparations
Psiadia penninervia is prepared as methanolic extracts to evaluate its potential as a botanical insecticide. These specific methanolic extracts were analyzed using HPLC to detect various flavonoid components within the plant. The study determined that the total flavonoid content in the Psiadia penninervia extract was 869.4 mg/kg. This preparation proved highly effective against aphids, yielding the lowest lethal concentration value among the tested species. However, the methanolic extract also showed a significant impact on the predator Chrysoperla carnea.
