N2  - Experiments were conducted at Cashew Research Station, Madakkathara 
and the Departments of Entomology and Pathology, College of Horticulture, 
Vellanikkara with the objectives of identifying high yielding cashew variety 
possessing resistance or tolerance to the Tea Mosquito Bug - Colletotrichum 
gloeosporioides complx and also to develop an effective and safer management 
strategy using pesticides. 
Screening of selected cashew grafts against tea mosquito bug (TMB) and 
Colletotrichum complex revealed that plants infected with TMB alone cause slight 
damage and may regain their growth after a period of time, but when the plants were 
	. 	\ 
inoculated with Colletotrichum and infected by TMB, the plants cannot regain their 
growth, once the die-back symptoms were incited. 
The variety 11-1600 was observed to be better as it IS comparatively 
tolerant to both TMB and TMB-Colletotrichum complex. The varieties Madakkathara- 
2, H-1610 and Kanaka also recorded lesser TMB damage. 
Inoculation with AMF resulted in greater germination percentage and 
enhanced growth attributes like height, number of leaves, number of roots, fresh 
weight and dry weight of plants. Among ,the insecticides, quinalphos and carbaryl 
were effective in reducing the TMB infestation. Combination sprays of carbendaziml 
copper oxychloride with quinalphos also proved effective against TMB- 
Colletotrichum pest complex. 
The scope of rationalising TMB management has been discussed in the 
light of the relative tolerance of the varieties and the need for judicious application of 
selected insecticides to contain TMB and of selected fungicides in conjunction to 
control the subsequent invasion by Colletotrichum gloeosporioides that may aggravate 
the die- back symptoms highlighted.
