Comparison of Energy Reserves in Prediapause and Diapausing Adult Sunn Pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae)
In this study, the energy reserves of prediapause and diapausing adult bugs were examined using colorimetric biochemical techniques to determine carbohydrates, lipids, glycogen, and protein content. To this end, 45-day-old bugs were obtained from three different sources: laboratory colony, cold-stored insects, or natural habitat. The results showed that prediapause males and females had significantly lower lipids than laboratory cultured bugs, those were collected in natural habitat, and cold-treated diapausing insects. In contrast to lipids, carbohydrate and glycogen contents were significantly higher in prediapause males and females than in diapausing insects. Glycogen content in laboratory-reared females and males were significantly higher than in their counterparts from natural habitat. In conclusion, Sunn pest energy reserves change from prediapause to diapause phases. Prediapause Sunn pest bugs accumulate lipids for their metabolic needs during diapause and for post-diapause functions that include dispersal and reproduction.
