摘要
通过调查发现在枸杞林内捕食性蝽类共有 4种 ,分别是食虫齿爪盲蝽DeraeocorispunctulatusFallen、异须微刺盲蝽CampylommadiversicornisReuter、蒙新原花蝽AnthocorispilosusJakovlev、微小花蝽OriusminutusLin naeus ,它们都捕食枸杞蚜AphisJsp .Gossypii、枸杞木虱ParatriozasinicaYangetLi等小型昆虫。其中食虫齿爪盲蝽D .punctulatusFallen数量最多 ,最常见。这种天敌喜欢潮湿阴凉的环境 ,室内测定每日能捕食枸杞木虱 15头。测定其捕食枸杞木虱的功能反应 ,数学模型为 :Na =0 .6 32 7Nt/ 1+0 .34 2
By means of the investigation it is turned out that there are four kinds of predatory bug in wolfberry woods.They are D.punctulatus Fallen?C.diversicornis Reuter?A. pilosus Jakovlev and O. minutus Linnaeus.They all can live on A.sp.Gossypii?P.sinica Yang et Li.D.punctulatus Fallen is the most one in number and prefers damp environment.It can predate P.sinicaYang et L 15 a day in lab.The function response of D punctulatus Fallen was tested a model is Na=0.327Nt/1+0.3428Nt.
