We also estimated the number of WBP indirectly predated by
the bat: when consuming a pregnant WBP, the bat also prevents
future offspring from hatching. Based on the proportion of pregnant
(Weihua, 1990) and winged females, and the survival rate
of WBP eggs (Zhu et al., 2004), we could project the prevented
damage by indirect suppression of the next WBP generation.
