茶多酚对亚洲玉米螟生长发育和生殖的影响
Effect of Tea Polyphenols on the Growth and Development of Ostrinia furnacalis
摘要
Abstract
[Purpose] In order to clarify the effect of tea polyphenols on the growth and development of Ostrinia furnacalis.[Method] The effect of tea polyphenols on the growth and development of O.furnacalis was studied by virulence feeding in indoor.[Results] The results showed that LC50 of tea polyphenols on O.furnacalis larvae was 2.185 0 mg/g.The relative growth rate,food utilization rate,food conversion rate and the approximate digestibility had no significant difference on O.furnacalis larvae.And the age of 4th instar larvae extended by tea polyphenols,there was significant difference among instar when tea polyphenols concentration was 1.6 mg/g,the difference in overall 5th instar age were not big.When tea polyphenols concentration was 2.4 mg/g,the pupal weight was significantly different but pupal duration was not.Tea polyphenols had no obvious effect on longevity of O.furnacalis adult.Tea polyphenols reduced the average fecundity per female,high tea polyphenols concentration (4.0 mg/g) group spawning amount was only 43.64％.In the low concentration group,the net reproduction of tea polyphenols group 0.8 mg/g was significantly difference compared with the control group (P ＜ 0.05),and the intrinsic rate of increase and the finite rate of increase were decreased.[Conclusion] Feeding tea polyphenols to 3rd instar larvae of O.furnacalis can effectively reduce the population of the offspring,which is beneficial to control it.关键词
