ABSTRACT

Natural infestation of Lac insect was observed for the first time in litchi while monitoring insect’s pest at the Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan in 1987/88. The newly established (< 5 years old) litchi orchard was free from any infection while nearly 50% of the trees in the old orchard (nearly 15 year old) were infested with this insect. Some of the trees showed heavy infestation covering most of the branches which revals that this insect can be considered as a serious problem in litchi fruit cultivation in the Chitwan valley. The good incrustation of lac provided that suitable host explored and studies carried out for its adaptation and development in this region.
