Abstract

Aim to study: The development of animals such as Lucilia sericata (Diptera: Calliphoridae), which are unable to regulate their body temperature metabolically and instead maintain a constant temperature by absorbing heat from their surroundings (i.e. poikilotherms), has been extensively described using the temperature collection model. This study aimed to investigate oviposition tendency and oviposition development times and ideal temperature and humidity values for mass rearing of the green bottle fly L. sericata, which was studied in the laboratory at three different constant temperatures (25 °C, 30 °C, and 35 °C) and three different constant humidities (35% relative humidity (R.H.), 50% R.H., and 65% R.H.).
Material and methods: The humidity was fixed at each experimental temperature to determine the maximum egg- laying and development time at different temperatures, and the number of days and degrees required to complete each stage was determined. The temperature was fixed in the different “””””” “humidity experiments, and the insectarium was examined under controlled conditions in a 12:12 (L:D) photoperiod cycle.
Results: A significant difference was obtained between the number of L. sericata eggs laying at different temperature values (χ2=21.143, p<0.05). A significant difference was found between the number of L. sericata eggs laying at different humidity values (χ2=17.913, p<0.05).
Conclusion: A temperature of 35°C and 50% humidity were identified as the optimal breeding conditions for the oviposition tendency of L. sericata flies in a specific insect house under laboratory conditions.
