Gelatine Grub on Tea in Nyasaland

Abstract

Gelatine grub appeared in vast numbers on two estates in one tea-growing area of Nyasaland in 1938 and again in 1939, resulting in almost complete defoliation of the bushes. It is known to be present in all the tea estates in the country as isolated individuals. Both local (China) and Indian jats are attacked, and it can be found on tea both under shade andwithout shade; the two infected estates, however, being without shade. Tea in any situation, on high ridges or in wet hollows, is equally infested.
