This research was designed to study and describe the biological cycle and behavior of the naranjilla borer, (Neoleucinodes elegantalis) in fields. The new information will address efficient Integrated Pest Management (IPM) strategies to control the insect.
1. Evaluate the effectiveness of light traps to capture the adults of Neoleucinodes elegantalis 2. To determine the efficacy of virgin-females to trap males of Neoleucinodes elegantalis 3. To describe different aspects of the Neoleucinodes elegantalis biology and behavior.
Researchers determined that larvae must not be kept in the rearing medium for more than 7 days. Longer periods of times produced rotten fruits and killed the insects. Use of sand allowed us to obtain more adults than the other media (soil and dry foliage). We recommend collecting dropped fruits from the field every four days to control the insect. If the fruit is left for longer than four days the larva will abandon the fruit and move to the soil to complete its life cycle.
