Biology and fertility life table of strawberry sap beetle reared on artificial diet

Abstract

The objective of this work was to determine the biological parameters and fertility life table of the strawberry sap beetle (Lobiopa insularis) reared on artificial diet in laboratory conditions. The duration and the average viability of the embryonic, larval, pupal, and egg‑to‑adult periods were: 4.1±1.5 days and 80.6%; 22.2±5.0 days and 60%; 10.8±2.3 days and 90%; and 37.1±8.8 days and 43.5%, respectively. The pre‑oviposition, oviposition, and post‑oviposition periods were 96±18.9, 133±27.5, and 77±16.3 days. The longevity of males (271±20.7 days) was lower than that of females (318±14.9 days). There is potential for using artificial diet based on strawberries for the multiplication of the strawberry sap beetle in laboratory.
