Compounds
Conditions
Ageratum houstonianum demonstrates significant biological activity by acting as an effective treatment against the mosquito Culex pipiens and the storage pest Tribolium castaneum. The plant extracts function as a potent antifeedant, discouraging insect consumption through various phytochemical properties. In the larvae of Culex pipiens, the plant specifically causes a measurable decrease in carboxylesterase activity. Furthermore, the extracts lead to a significant decrease in cytochrome P-450 monooxygenase activity. These diverse biochemical and behavioral effects highlight the plant's broad potential as a natural insecticidal agent.
Preparations
Ageratum houstonianum is prepared as crude leaf extracts to study its ability to deter the oviposition of various mosquito species. Researchers have also utilized Ageratum houstonianum prepared as methanol crude leaf extracts to demonstrate effective deterrent activity against vectors like Aedes aegypti. Specifically, the plant is prepared as a methanol extract to achieve high deterrence rates in both laboratory and field trials using ovitraps. Furthermore, Ageratum houstonianum is prepared as oils to test its insecticidal and repellent capacities against storage pests such as Tribolium castaneum. Finally, the species is prepared as a plant extract to evaluate its antioxidant and cytotoxic activities based on altitudinal variations.
