During my work at the Agricultural Research Station.Taliparamba in 1933.I observed the presence of Pempheres affinis adults on almost all hibiscus esculentus plants found on the Farm. By keeping the stems.adult insects were also reared out.With a view to ascertain whether the insect was attacking cotton.or was only a casual visitor to the Hibiscus esculentus plants a minute examination of all the varieties of cotton-Uganda.Buganda,Durango,Zululand Hybrid.and Karunganni--was made.Itwas an agreeble surprise to find that all the cotton varieties showed complete immunity from Pempheres infestation.
