Biology of Neoleucinodes elegantalis (Guenée 1854) (Lepidoptera: Crambidae): pest of economic importance of naranjilla, an Amazonian fruit of Ecuador

Abstract:

The fruit borer, Neoleucinodes elegantalis (Guenée 1854) is the main pest infesting naranjilla crop (Solanum quitoense) in Ecuador, causing up to 70% loss of production. This research describes the biology of this insect in a laboratory environment simulating the subtropical environment of the Amazonian Andes (average temperature of 24 ± 1 °C and relative humidity of 85%). Adult insects were sexed, a population created with a ratio of two males for each female and larvae were reared in unripe naranjilla fruits. Eggs were placed on the fruit in masses of 3 to 15 units. Five larval instars were confirmed according to width of the cephalic capsules with a total larval duration of 20.4 ± 0.13 days. The pupal stage lasted 13.02 ± 0.35 days. Male adults had longevity of 10.06 ± 1.75 days and females 10.86 ± 1.30 days. Finally, pre-oviposition period lasted 2.67 ± 0.72 days, oviposition 4.33 ± 1.90 days and post-oviposition 3.87 ± 1.13 days.
