Abstrakt: Background: Anisopteromalus calandrae (Howard) is a solitary ectoparasitoid with wide-ranging potential applications as a natural biological control agent against various coleopterous pests in food warehouses. Implementing an effective cold storage program is crucial for extending the shelf life of biological control agents and ensuring their stable and abundant supply. Herein, we attempted to determine the optimal cold storage conditions for Anisopteromalus calandrae by investigating the effect of cold storage at three different temperatures (7, 13, and 19 °C) for 7, 21, and 35 days on four developmental stages (late-instar larvae, early-stage pupae, mid-stage pupae, and 2-day-old adults). Additionally, we explored the maximum cold storage potential by observing early-stage pupae stored at 13 °C for various durations (30, 60, 90, 120, and 150 days).
Results: The most suitable cold storage temperature for the early-stage pupae of Anisopteromalus calandrae was 13 °C, and the highest adult emergence rate (98.3%) was after 90 days of storage at 13 °C. Furthermore, we did not find any significant effect on longevity (female: 44.3 days; male: 38.1 days) or fecundity (121.7 wasps). The female ratio ranged from 43.5% to 50.8%. More importantly, cold storage did not adversely affect the developmental duration or fecundity of the offspring.
Conclusion: This study offers crucial insights for managing Anisopteromalus calandrae populations under laboratory conditions and lays the foundation for potential industrial production and development. © 2023 Society of Chemical Industry.
