A field study of a population of coffee berry borer, Hypothenemus hampei (Coleoptera; Scolytidae), in Chiapas, Mexico
A coffee berry borer population was sampled regulary over a 16-month period a plot of arabica trees in Chiapas, Mexico. Berries were classified according to whether they contained pre-reproductive, reproducing, or post-reproductive females; there were marked seasonal differences in relative abundance of these categories. Immature stages were present throughout the year and large numbers of females accumulated in berries in the dry season, particularly in fallen berries. These females emerged with the onset of the rainy season. In a mixed plot of robusta and arabica trees, egg laying began in robusta berries towards the end of the arabica harvest. Practical advice on the correct timing of crop sanitation, spraying, and parasitoid release is given, stressing the importance of monitoring the phenology of both borers and coffee berries.
