ABSTRACT
Exploring the impact of low-temperature storage on the fitness of natural enemy insects is crucial for practical field applications because this parameter directly influences their potential for population growth and effective pest control. Eocanthecona furcellata (Wolff) (Hemiptera Pentatomidae) is widely used in biological pest control. This study aimed to identify optimal storage stages, temperatures, and durations for E. furcellata to produce high-quality individuals for practical use. The quality of E. furcellata after storage was evaluated by assessing parameters such as predatory capacity and fecundity, along with age-stage, two-sex life table. The findings revealed that the adult stage was the optimal storage form for E. furcellata, and the most favorable temperature for storage was 12â
°C. Adult females had the highest predatory ability after 15â
days of storage at 12â
°C. Although survival rates declined with prolonged storage, they remained above 50% after 30â
days, and longevity, fecundity, and predatory capacity of surviving individuals remained comparable to those of individuals in the control group (rearing at a constant temperature of 26â
°C without low-temperature storage). The effects of low-temperature storage extended to the F1 generation of E. furcellata, which exhibited maximum mean longevity, fecundity, net reproductive rate, and mean generation time as well as fastest population growth after 30â
days of storage at 12â
°C. These results can be used to achieve optimal low-temperature storage conditions for E. furcellata production, particularly for extending its shelf life.
