Description
Alfalfa or Lucerne, Medicago sativa L. recognised as the oldest among the forage crops, also called as Queen of forages is considered as a superior feed for dairy, horses etc because it is quickly digested, relatively high in protein, low in NDF, excellent source of Ca, Mg, P, vit D and carotene. As a legume it is also known to improve soil structure because it is effective source of biological nitrogen. It mainly suffers both qualitatively and quantitatively from the spotted alfalfa aphid, Therioaphis maculata and pea aphid, Acyrthosiphon pisum. Green fodder yield losses were reported to be 33% in alfalfa due to aphid in new Mexico. Since insecticide usage is discouraged in fodder crops, it was intended to manage the spotted alfalfa aphid with few of the available biopesticides.
