Ecological Characteristics of Aphidophagous Menochilus Sexmaculatus Fabricius and its Performance Against Aphis Gossypii Glover

The chilli aphid, Aphis gossypii Glover (Homoptera: Aphididae) (here after abbreviated as AG), is vector of the chilli veinal mottle virus (CVMV) and is a main pest of chilli in Malaysia. The aphidophagous Menochilus sexmaculatus Fabricius (Coleoptera: Coccinellidae) (here after abbreviated as MS...
