Abstract

The cultivation of sugarcane is one of the most economically important agro-industrial crops in Panama, and it is affected by primary and secondary insect pests.  The objective of this study was to evaluate three techniques for the capture and population fluctuation of the sugarcane beettle Oediopalpa guerini Baly associated with sugarcane cultivation in Natá, Coclé.  The study area was established within a plot of sugarcane of the E07-06 variety in Natá. Collections were made over 12 months.  Ten sampling points were established consisting of sugarcane areas of 16m² each. Sampling was conducted using three types of sampling techniques (manual collection with plastic bags and capture using two models of recycled PET plastic traps).  The entomological materials collected from the O. guerini species were brought to laboratory conditions.  The population fluctuation of the insects was determined by associating it with precipitation (mm), monthly.  The results indicate that there were statistically significant differences between the treatments (P < 0.05), where manual capture was superior (average capture of 0.225 specimens per sample).  The highest specimen captures occurred during the months of July (6), August (9), and November (10) of 2023, all primarily due to manual captures.  There is a moderate correlation coefficient of 0.6055 indicating a moderate relationship between the presence of the beetle specimens and total monthly precipitation. The conclusions indicate that the most effective technique for capturing adult beetles was manual collection compared to captures with the two types of traps used during the study.  There is a relationship between the presence of beetle populations and the increase in rainfall during the rainy season in a specific area.  This information is key for forecasting potential attacks by this pest on sugarcane.
