Guava (Psidium guajava) is ever green fruit, belongs to Myrtacae family. It grows in tropical and sub-tropical area of the world and it is important source of vitamin C. The survey was conducted to identify the insect pest of guava in four villages of sub-zoba Hamelmalo viz. Fredarb, Genfelom, Wazntet, and Hamelmalo. The main objective of the study was to identify the major insect-pests of guava. The surveys were carried out by providing questioner to the farmers and observations on fruits. Guava fruit fly (Bactrocera sp.) is found to be the major insect-pest. Fruit fly infestation was observed in 89 per cent number of trees. Out of the four villages, the infestation of fruit fly was highest in Hamelmalo and Wazntet (94%) and the lowest was in Fredard (78%). Estimation of the fruit dropping due to fruit fly was made and it was found that average fruit dropping in different villages by fruit fly was maximum in Wazntet 100 per cent during summer and 22 per cent during winter season. Minimum average fruit dropping during summer season was 85 per cent in Genfelom and during winter season it was 14 per cent in Fredard.
