An epidemic outbreak of lac insect Kerria lacca on sandal and its host trees at Gottipura and Nallal in Hoskote range (Karnataka) is reported. It is found that 24.5% of the trees were heavily affected (9.3% of which are dead), 25.5% had medium attack and 50% were completely free. To control the lac infestation, the affected branches were lopped off, burnt and an insecticide viz., Ekalux 20AF 0.5% mixed with 0.05% sticker was sprayed on the tree. The treated trees were watered. This has completely controlled the lac infestation on sandal. A second spray with any insecticides, like Rogor 30 EC, Fenvalerate, Cypermethrin or Dimethoate, may be sprayed after formation of new flush of leaves, to check further secondary infection.- A New Record of the Insect Defoliator, Pteroma plagiophleps Hamp.

During the current entomolgical investigations on the spike disease of sandal, Nephotettix Virescens (Distant) was incriminated as an insect vector transmitting the spike disease of sandal in nature in some of the areas. Earlier two species of leaf-hoppers namely Coelidin indica Walker (=Jassus indicus Walker) and Moonia albimaculata Walker (Homoptera : Cicadellidae) were reported to have been incriminated as insect vectors of spike disease of sandal. Experimental transmission of spike disease of sandal through the insect vector, Nephotettix Virescens Distant (Homoptera : Cicadellidae) commonly known as "Rice Green leaf-hopper" is presented in this paper. At least sixty leaf-hoppers were required for disease transmission in the transmission cages. The insect transmission of disease was confirmed by biometrical ratios, stain test and retransmission by grafting.- Occurrence of Lantana Lace Bug.
