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 8Nt
According to the investigation, there are four predatory stinkbugs in Lycium barbarum, which are DeraeocorispunctulatusFallen, CampylommadiversicornisReuter, AnthocorispilosusJakovlev and OriusminutusLin naeus, all of which prey on AphisJsp Gossypii, Lycium psyllid ParatriozasinicaYangetLi and other small insects. Among them, the largest number of D. plumatulatusFallen is the most common and the most common. This natural enemies like damp and cool environment, indoor test daily predation of 15 medlar psyllid. Determination of its response to the medullary psyllid function response, the mathematical model is: Na = 0 .6 32 7Nt / 1 +0 .34 2 8Nt
