This paper redescribes the morphological charcters of the antennae and forewings of Trichogramma. The female antenna was descriipted as 6 segmented: scape, pedicel, anell us, two funicles and a solid club. But there are actually two anelli between the pedicel and the funicle. The first anellus short and minute, the second wedge-form, jointed closely to the first funicle. The male antenna was descripted as 4 segmented, scape, pedicel, anellus and flagellum. But observed by the scanning electronmicroscope, as...

This paper redescribes the morphological charcters of the antennae and forewings of Trichogramma. The female antenna was descriipted as 6 segmented: scape, pedicel, anell us, two funicles and a solid club. But there are actually two anelli between the pedicel and the funicle. The first anellus short and minute, the second wedge-form, jointed closely to the first funicle. The male antenna was descripted as 4 segmented, scape, pedicel, anellus and flagellum. But observed by the scanning electronmicroscope, as well presents the second anellus, jointed more closely to the base of the first funicle.lt may be seen only at the outer view. Be sidesi, at the base of the flagellum compared to the female funicles, there are two funicle sclerites on the ventral side. The funicle sclerites are not the true segments. With the second anellus, show the morphological homogensity of the male and female antennae. This paper also redescribes the venation and the cilia vein tracks of the forewings. The morphological character redescription of the antennae and forewings may be helpful to the diagnosis of the Trichogramma.

本文补充描述赤眼蜂属的触角和前翅的形态特征。在赤眼蜂属雌性触角中,过去一般描述为由6节组成,即柄节1节、梗节1节、环状节1节、索节2节、锤节1节。通过电镜观察,认为应有2个环状节,称为第1环状节及第2环状节,第2环状节楔形,与第1索节基部紧密相连。在赤眼蜂属雄性触角中,过去一般描述为由4节组成,即柄节1节、梗节1节、环状节1节、棒节1节,其棒节由相应于雌性触角的两索节及锤节愈合而成。通过电镜观察,认为亦存在第2环状节。第2环状节更紧密地镶入第1索节的基部,仅在外侧面观才易于发现。同时,相当于雌性触角的第1索节及第2索节的位置上,在腹面及两侧可见第1索片及第2索片。这两索片显示雄性触角棒节的不完全分节,同样显示雄性触角与雌性触角在形态结构上的联系。本文同时重新描述前翅上的翅脉于前翅表面及底面的毛列,并给予相应的名称。触角及前翅毛列的补充描述可能有助于该属的分类及种间区别的进一步研究。

本文记述了我国常见的切叶蚁亚科(Myrmicinae)大头蚁属(Pheidole)的两个新种.本属的主要特征是:工蚁明显地分为大型工蚁(兵蚁)和小型工蚁(工蚁);分类学上主要以大型工蚁为主、小型工蚁为辅.大型及小型工蚁的触角末端的触角棒由3节组成,少数由4节组成.本文描述的两个新种,均由4节触角棒组成.

Eight populations of Trichogramma dendrolimi were collected from De ndrolimus superans,D.tabulaeformis,D.spectabilis,D.punctata and D.kikuchii in 8 provinces or municipality of China.They were propagated with eggs of Co rcyra cephalonica in a rearing room of constant temperature and humidity with 14 hours photophase.Both parental and filial generations were examined for morph ological diagnosis.Structures of the male genitalia of the 8 populations were fo und identical.Yet the populations could be divided into three rather distinctive groups according to the ratio of the length of flagellum setae over the width o f antenna flagellum.The differentiation among the three groups appeared to be ge ological.The populations from Beijing and Inner Mongolia,which are in high latit ude,had long setae,those from Yunnan and Hunan Provinces,in low latitude,had sho rt setae;while the remaining four populations had medium length setae were from Guangxi,Shandong,Zhejiang and Jilin Provinces.ANOVA and Ducan′s test were used in data analysis.

从我国8个省(市)的落叶松毛虫、油松毛虫、赤松毛虫、马尾松毛虫和思茅松毛虫中采到的8个松毛虫赤眼蜂种群,经米蛾卵饲养后,亲代及子代均用于形态学观察。这8个种群的雄外生殖器构造相当一致,但根据雄虫触角棒节上刚毛的相对长度可以分成3组。表现出有明显的种群地理分化。位于较高纬度的北京和内蒙古种群属长毛组、触角棒节上刚毛相对较长;位于较低纬度的湖南和云南种群属短毛组;来自吉林、山东、浙江和广西的4个种群属中毛组
