南京地区稻田福寿螺的发生动态及习性调查与分析
Investigation and analysis of the occurrence dynamics and behavioral characteristics of Pomacea canaliculata in paddy fields of Nanjing region
摘要
Abstract
As a notorious invasive species,Pomacea canaliculata has posed a significant threat to rice production in Nanjing area.From 2022 to 2023,we investigated the occurrence dynamics,oviposition preferences in field conditions,and analyzed the damage to rice seedlings caused by P.canaliculata in Lishui District,Nanjing City.The results showed that,(1)in irrigation ditches,the egg-laying amount of P.canaliculata on bamboo strips was positively correlated with daily minimum temperature.(2)In rice fields with Zizania latifolia cultivation and bamboo strips,P.canaliculata preferentially laid eggs on bamboo strips,and no significant difference in egg quantity was observed among different Z.latifolia varieties.(3)Compared to the center of the field,P.canaliculata tended to lay eggs on bamboo strips near the field ridges.(4)Crop residue attraction experiments demonstrated that watermelon residues or watermelon-tomato mixtures effectively attracted P.canaliculata in fields.Damage assessment revealed the highest P.canaliculata den-sities(6 and 13 adults per five m2)were near paddy inlets,resulting in 1/5 and 1/3 seedling loss,respectively,whereas central areas showed a lower density(two adults per five m2)and negligible seedling damage(0-2 plants).Based on these findings,future management strategies should prioritize optimizing the design and placement of attraction(elimination)de-vices near ridges or field corners,enhancing monitoring and isolation measures at paddy inlets,and integrating winter-spring dredging to establish an eco-friendly integrated management system.This study provides a scientific foundation for precision control of P.canaliculata in Nanjing rice fields.关键词
