To record the presence and damage caused by the borer moth larvae in the avocado fruit Stenoma catenifer Walsingham (Lepidoptera: Elachistidae) in Panama. We collected 560 fruits of Persea Americana, of the Antillana varieties, from 12 avocado trees. We performed six visits to the plantation in the community of Altos del Maria in Sorá, District of Capira, province of West Panama. The site locates at 8º 38’ 32.1 “Latitude N, 80º 02’ 03.4” Length W, at an altitude between 487.68 and 1005.8 meters. We kept the collected samples in 28 breeding chambers at a temperature of 25 ± 2 ° C; 58 ± 10% relative humidity and photoperiod 9 hours of light. The 12 trees showed severe attacks by the borer moth of the S. catenifer avocado. We did not observe any defoliation in the leaves by S. catenifer larvae. The damage caused by the insect was notorious by the presence of exudations and reddish colorations at the inlet of the galleries in the fruits and seeds. Attacks to the fruit generally occurred in cracks or grooves, in shaded areas where the fruits were distributed along the branches. In the evaluations, we identified natural enemies. 12 individuals of the predator known as Euborellia annulipes (Lucas 1847) Dermaptera: Anisolabididaeinside were inside 10 avocado seeds in the soil. The incidence of avocado fruit borer larvae; S. catenifer was 40% for each avocado tree. The presence of the pest in avocado crops at the sampling site was high. In addition, the scope of local distribution of the borer moth of the S. catenifer avocado fruit extends to the center of the country, but it is still reported for elevations above 500 meters above sea level.
