胚后发育期臭腹腺蝗中的血细胞种类(英文)

Hemocyte populations in Zonocerus variegatus(L.)(Orthoptera:Pyrgomorphidae)during post-embryonic development

应用血球计数器统计了胚后发育期臭腹腺蝗Zonocerus variegatus中存在的血细胞类型和数目。从1龄幼虫至成虫的发育阶段中共观察到6种血细胞类型,即原血细胞(PRS)、浆血细胞(PLS)、粒细胞(GRS)、珠血细胞(SPS)、绛色细胞(OES)和adipohaemocytes(ADS)。不过,在1龄幼虫期未发现OES。在这6种血细胞中,PLS的总平均数最高,OES的总平均数最低。成虫期的血细胞数目显著高于其他发育阶段(P<0.05),而1龄幼虫和2龄幼虫期的血细胞数目不存在显著差异(P>0.05)。

The focus of this study is to examine the trend in the number and types of hemocytes in all the developmental stages of Zonocerus variegatus.The types and number of hemocyte cells present in Z.variegatus during post-embryonic development was evaluated with the aid of hemacytometer.Six hemocyte cells were observed in all the developmental stages from the 1st instar larva to the adult stage,namely：prohaemocytes（PRS）,plasmatocytes（PLS）,granulocytes（GRS）,sherulocytes（SPS）,oenocytes（OES）and adipohaemocytes（ADS）.However,OES was not found in the haemolyph of 1st instar larval stage.PLS had the highest total mean count while OES had the least total mean count of all the six hemocytes.The adult stage had significantly（P0.05）higher hemocyte count relative to other developmental stages,however,no significant difference（P0.05）existed between the hemocyte count of the 1st and the 2nd instar larval stages.This study shows that the adult stage is immununilogically able to adapt to the environment better than other lower developmental stages.
