Effects of prey species and honeydew feeding on development and reproduction of the mirid bug, cyrtorhinus lividipennis REUTER (heteroptera: miridae)

摘要

The mirid bug, Cyrtorhinus lividipennis REUTER, showed no significant difference in either nymphal developmental time, preoviposition period, adult longevity, or total fecundity between bugs reared on the eggs of two planthoppers, the whitebacked planthopper (Sogatella furcifera HORVATH) and the brown planthopper (BPH, Nilaparvata lugens STAL). The mean number of eggs (248.1 eggs) laid by C. lividipennis females fed on BPH eggs with one pair of BPH adults was significantly higher than that of females (66.1 eggs) fed on BPH eggs without one pair of BPH adults. This suggests that higher reproductivity in C. lividipennis is achieved when sufficient eggs are available. The nymphal developmental time and preoviposition period of C. lividipennis fed on BPH eggs with honeydew produced by BPH males were significantly shorter than those of individuals fed only BPH eggs. Honeydew feeding also prolonged adult longevity and increased total fecundity. These findings indicate that honeydew has a positive effect on the development and reproduction of C. lividipennis.
