Effects Of Crude Extracts Of Birbira (millettia Ferruginea) Seed Powder In Solvents Of Different Polarity Against Pea Aphid Acyrthosiphon Pisum

This study was conducted in order to test for the contact toxicity and settling deterrence ofrncrude extracts of birbira, Millettia ferruginea, seeds powder in solvents of differenagainst pea aphid (A. pisum).
