Maximum Titers of Vitellogenin and Total Hemolymph Protein Occur during the Canalized Phase of Grasshopper Egg Production

Abstract: Many organisms exhibit developmental plasticity only in sensitive phases and cannot respond to environmental perturbations at other times. However, we know little about the physiological events that define plastic and canalized phases. During egg production in insects, vitellogenin (Vg) accumulates first in the hemolymph and then in the eggs. In addition, storage proteins may be important resources for egg production. Therefore, we tested hypotheses on the relationships of Vg and TP (total hemolymph protein mi… Show more

“…Sampling age strongly affected the hemolymph protein levels ( Fig. 5; Pillai's Trace; F 6,21 = 39.1; P < 0.0001), as has been shown previously (e.g., Hatle et al 2001). There was also a significant interaction of diet and sampling age (F 18,69 = 1.96; P = 0.031), suggesting that the diets responded differently to the passage of time.…”

“…Results for the 60% diet were similar. More severe food limitation in this grasshopper (30 -40% of ad libitum) reduced hemolymph protein levels by 40%, without halting reproduction; this result was highly statistically significant and was repeatable across two experiments (Hatle et al 2001;. That life-extending CR did not alter protein storage is particularly surprising for a phytophagous insect, because they are protein limited during major life history transitions (e.g., Hatle et al 2003a;Hatle et al 2006).…”
