南美斑潜蝇不同种群生物学特征的比较分析OA北大核心

The invasive leaf miner Liriomyza huidobrensis is a notorious pest of vegetables and flowers in China.Un-derstanding the biological performance of different populations of L.huidobrensis provides the foundation for clarifying its adaptability to novel environments.In this study,various biological characteristics,including egg production,egg hatch-ing rate,pupation rate,eclosion rate,and pupal morphology,were assessed within three L.huidobrensis populations:Yunnan cowpea,Yunnan luffa,and Xinjiang tomato.The results showed that the number of eggs and pupal length of L.huidobrensis on tomatoes in Xinjiang were significantly lower than those in the Yunnan cowpea population,while its emergence rate and developmental duration were significantly higher than those in the Yunnan luffa population.However,there was no significant difference in egg hatching rate,pupation rate,pupal width,and pupal weight among the three populations of L.huidobrensis.This study found that both host plants and geographic factors can potentially affect the re-productive and other biological characteristics of L.huidobrensis populations.The results provide a vital theoretical basis for understanding the invasion and environmental adaptation of L.huidobrensis,as well as for implementing environmen-tally friendly control strategies.
