龙爪槐花对异色瓢虫成虫寿命的影响
Effects of Sophora japonica f.pendula Flowers on the Longevity of Harmonia axyridis Adults
摘要
Abstract
In this paper,we tested the effect of Chinese pagoda tree Sophorajaponica f.pendula flowers and their main sugars on longevity ofHarmonia axyridis adults.Adults provided with S.japonica flowers had longer average longevity (female:10.96 d,male:10.83 d) than those only with leaves (female:3.98 d,male:3.65 d) under laboratory conditions.Similarly,adults longevity was significantly longer on inflorescences (female:14.72 d,male:15.46 d) than on branches (female:3.90 d,male:3.82 d) under field conditions.When the adults were provided with each of the four sugars (glucose,fructose,sucrose and maltose) as nutrient supplement,their longevity prolonged significantly.The results indicate that the pollen and nectar from S.japonica flower rich in sugars are suitable food sources for H.axyridis adults,and may play a key role in sustaining populations of the predatory ladybeetle when aphid prey is absent.关键词
