Abstract

Conotelus sp. (Coleoptera: Nitidulidae) is documented in passion fruit plantations in the state of Rondônia, Brazil, where producers have reported losses of approximately 80%. Damage is higher than that caused by traditional passion fruit insect pests, and there are no effective control methods. Flowering phenology is a key factor in insect attraction and recurrence. The beetles attack flowers, and a larval preference for pollen was shown. This insect can complete its life cycle in flowers on the ground. Damage characteristics, the distribution of the insect, changes in population size, and possible causes of outbreaks are reported.

 

Sumario

Conotelus sp. (Coleoptera: Nitudilidae) está documentado en las plantaciones de maracuyá en el Estado de Rondonia, Brasil, donde los productores han reportado pérdidas de aproximadamente del 80%. El daño es mayor que la causada por las plagas tradicionales de plagas de maracuyá y no existen métodos eficaces de control. La floración fenología es un factor clave en la atracción y la recurrencia de insectos. Los escarabajos atacan las flores y las larvas demuestran una preferencia para el polen. Este insecto puede completar su ciclo de vida en las flores sobre el suelo. Se reportan las características de daño, la distribución del insecto, el cambio del tamaño de la población y las posibles causas de los brotes de infestación.
