ẢNH HƯỞNG THỜI VỤ NHÂN NUÔI ĐẾN KHẢ NĂNG SINH TRƯỞNG CỦA RUỒI LÍNH ĐEN (HERMETIA ILLUCENS) TRÊN ĐỊA BÀN TỈNH THANH HÓA

Abstract

The growth and development of the black soldier fly (Hermetia illucens) are significantly influenced by temperature and humidity conditions throughout the year. The size of larvae, pupae, adult flies, and the number of eggs laid by a female fly are highest when rearing black soldier fly from April to March, as the ideal temperature ranges between 25°C to 35°C and humidity levels range from 60% to 70%. From February to June, the size of larvae, pupae, adult flies, and egg yield is dramatically reduced due to high temperatures and low humidity, which negatively impact the growth of black soldier fly. Additionally, when the average temperature is lower than the optimal temperature for black soldier fly, their growth lasts longer. The black soldier fly life cycle is shortest from May to September, lasting from 40.1 to 40.8 days. However, the life cycle spans 42 to 44 days when rearing black soldier fly from March to June. The longest black soldier fly life cycle recorded was 54.8 days in February when the average temperature was at its lowest.
