研究自然条件下取食经历对云南紫胶虫的影响.结果表明:母代取食经历相同,子代在不同寄主植物上寄生时,在不同寄主植物之间种群密度存在一定差异;有效性比只是聚果榕与牛肋巴上存在显著差异,在其他寄主植物之间,有效性比差异不显著;偏叶榕上与聚果榕和南岭黄檀上种群死亡率存在显著差异,而在聚果榕与南岭黄檀之间其种群死亡率没有显著差异;聚果榕和南岭黄檀上生殖力(单雌怀卵量)存在极显著差异,偏叶榕和南岭黄檀上云南紫胶虫生殖力存在极显著差异,而在聚果榕与偏叶榕之间生殖力没有差异;世代净增殖率在不同寄主植物之间存在一定差异.而母代取食经历不同,子代在同一种寄主植物上寄生时,种群密度不存在差异,有效性比、种群死亡率、生殖力均存在显著差异.在南岭黄檀和偏叶榕上取食1个世代后的种群,在偏叶榕上寄生时,其世代净增殖率无差异;在聚果榕和南岭黄檀上取食1个世代后,在聚果榕上寄生时,其世代净增殖率有极显著差异.
研究自然條件下取食經歷對雲南紫膠蟲的影響.結果錶明:母代取食經歷相同,子代在不同寄主植物上寄生時,在不同寄主植物之間種群密度存在一定差異;有效性比隻是聚果榕與牛肋巴上存在顯著差異,在其他寄主植物之間,有效性比差異不顯著;偏葉榕上與聚果榕和南嶺黃檀上種群死亡率存在顯著差異,而在聚果榕與南嶺黃檀之間其種群死亡率沒有顯著差異;聚果榕和南嶺黃檀上生殖力(單雌懷卵量)存在極顯著差異,偏葉榕和南嶺黃檀上雲南紫膠蟲生殖力存在極顯著差異,而在聚果榕與偏葉榕之間生殖力沒有差異;世代淨增殖率在不同寄主植物之間存在一定差異.而母代取食經歷不同,子代在同一種寄主植物上寄生時,種群密度不存在差異,有效性比、種群死亡率、生殖力均存在顯著差異.在南嶺黃檀和偏葉榕上取食1箇世代後的種群,在偏葉榕上寄生時,其世代淨增殖率無差異;在聚果榕和南嶺黃檀上取食1箇世代後,在聚果榕上寄生時,其世代淨增殖率有極顯著差異.

In nature,the effects of foraging experience on Kerria yunnanensis offspring population were studied.With the same foraging experience,the offspring of K.yunnanensis had different population density on different host tree species.The realized sex ratio of offspring had significant difference between Ficus glomerata var.chittagonga and Dalbergia obtusifolia,but no significant difference between other host trees.The offspring population mortality had no difference (P>0.05) between Ficus glomerata var.chittagonga and Dalbergia balansae,whereas it had significant difference (P<0.05) between other host trees.There was extremely signifcant difference (P<0.01) in oviposition of offspring female between Ficus glomerata var.chittagonga and Dalbergia balansae,between Ficus cunia and Dalbergia balansae,but there was no difference (P > 0.05) between Ficus glomerata var.chittagonga and Ficus cunia.R_0 had certain difference among all host trees.With different experience,the offspring of K.yunnanensis had the same population density on the same host tree species,had different realized sex ratio,population mortality and oviposition (P < 0.05).After one life cycle on Dalbergia balansae and Ficus cunia,the R_0 on Ficus cunia had no difference (P > 0.05),after one life cycle on Dalbergia balansae and Ficus glomerata var.chittagonga,the R_0 on Fictts glomerata var.chittagonga had extremely significant difference (P <0.01).
