Temperature-dependent development and emergence pattern of Hypothenemus hampei (Coleoptera: Curculionidae: Scolytinae) from coffee berries
Journal of Economic Entomology 103 (4), 1159-1165
Abstract: The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), is the most important constrain for coffee production throughout the world. Knowledge on the emergence pattern of H. hampei females to infest new berries is crucial to effectively plan control measures. In this laboratory study, we assessed the development of immature stages and the emergence pattern of H. hampei females from the berries by exposing them to temperatures that are typical for high-altitude plantations (>1,700 m above sea level [masl]) or when coffee is grown under shade trees (20-22°C), and optimum altitude plantations (1,200-1,600 masl) or nonshaded coffee (25-30°C). Fecundity and emergence pattern of H. hampei females from coffee berries varied with temperature. Temperature played a crucial role determining the rate of H. hampei development and therefore the emergence of the females to start a new infestation cycle. The emergence and colonization phases of new colonizing females in coffee plantations with mean temperatures of 20, 25, or 30°C would take place at different moments in the development of the coffee berries, and in some cases more than once. The implications of our findings for an improved, site-specific timing of control interventions against H. hampei are discussed.
