A survey was conducted during June 1997-December 1998 in and around Shillong, Meghalaya, India, to assess the incidence of the litchi trunk borer Aristobia testudo in guava orchards. Damage by A. testudo ranged from 8.1 to 76% in different orchards. Among the 1068 plants surveyed, 431 were killed due to A. testudo incidence. Among the cultivars, Lucknow-49 recorded a mean infestation of 76% in 10-year-old plants and 22.72% in 8-year-old plants. Young plants were killed within one-year of infestation and trees less than 10 years old were severely damaged. This is claimed to be the first record of A. testudo on guava.
