- Abstract
Due to the increment of damages in papaya (Carica papaya L.) plantations caused by the incident of Davara caricae Dyar (Lepidoptera: Pyralidae) in different regions in the country, a study was carried out to determine bio-ecological aspects of Davara caricae in Cuba. Experiments were conducted at the Reproduction Center of Entomophagous and Entomopathogens from the Agricultural Enterprise, Santo Domingo, from March to December, 2010. Results showed that the insect cycle from march to April with an average temperature of 22,4 °C was 28,76 days, while in the period from July to August with an average temperatura of 27.1 °C increased to 23,91 days. In relation to adult longevity, insects emerging in May with an average temperature of 26.7 °C showed a longer longevity (14.50 days for females and 13.60 days for males) than insects emerging in December with 23.3°C, (11.25 and 10.30 days, respectively). Besides, results also showed a longer longevity for females. Aspects related to oviposition were influenced by temperature.
