The present article deals with the important morphological characters of the eggs, larvae and metamorphosed fries of two flat fishes, Paralichthys olivaceus (T. & S.) and Zebrias zebra (Bloch), based mainly upon the living specimens reared successfully in our laboratory since 1959. Besides, the diagonostic characteristics for the identification of the eggs of P. olvaceus, the characteristics common to the eggs and larvae of the genera Paralichthys, important characters of the eggs and larvae of Zebrias zebra, and the relationships between the eye and the anterior end of the dorsal fin in P. olivaceus and in Zebrias zebra during the migration of the eye are discussed.

本文主要根据1959年以来在实验室内饲养的活材料,对牙鲆(鲆科)和条鳎(鳎科)两种鲽形目鱼类卵子及仔、稚鱼各种重要阶段的形态特征作了描述,以供鉴定之用。这两种鱼类仔鱼变态期和条鳎卵的详细形态特征均未见记载。 1.牙鲆 卵浮性,呈圆球形;卵膜光滑,无粘性;卵黄均匀。卵径0.83—1.10毫米,生殖初期的最大。油球一个,球径.0.15—0.22毫米,也是初期最大。胚体、鳍褶和卵黄囊上的色素分布广而分散。初孵仔鱼全长2.07—2.44毫米;肌节12(13)+26,体部及鳍褶上色素分散,21对肌节以后的鳍褶上没有色素。仔鱼时期背、臀鳍褶边缘出现扫帚状黄、黑色素。仔、稚鱼无鳔;其鳍前端的6—7根鳍条首先发育,形成冠状幼鳍。全长12.7—14.6毫米(孵化后约30天)、右眼转过头顶时,鳍式巳与成鱼完全一致;此时稚鱼已由水平游泳转变为底层活动。全长14.0毫米以上时(孵化后约35天),右眼已完全转到左侧(有眼侧);全长达到20.3—25.5毫米(约孵化后42—45天)时,鳞片完全长出。 2.条鳎 卵子也是浮性、圆球形的。卵径为1.45—1.68毫米。油球小而多,10—60个左右。胚体上黄色素极多。卵膜无粘性,有...

The present paper contributes a knowledge of the wood structure of Tsoongioden- dron odorum Chun,a new monotypic genus of the family Magnoliaceae.The anato- mical features of this wood are described as follows. Wood diffuse-porous;pores 53—80 per sq.mm.,solitary or multiple in radial groups of 2—3(may up to 7),pore clusters also oceured but rare,more or less angular in shape;vessel perforations scaraliform,with 1—8 bars,generally 2—3 or 4,inter- vascular pittings searaliform,fine spiral thiekenings also present,vessel segments 650—1020 μ,generally 1500 μ long;wood rays of heterogeneous type IIB rarely IIA with 1,sometimes 2—3 rows of upright cells on both margins,oil cells present in some occasion,uniseriate rays 3—9 cells,135—270 μ,generally about 7 ceils,185 μ high, the multiseriate rays up to 7 cells,65 μ,generally 2—3 cells,45 μ wide and 14—32 cells 415—830 μ,generally about 28 cells,621 μ in height;fiber tracheids 650—2000 μ, generally 1500 μ long;wood parenchyma terminal,narrow banded(2—3 cells wide), rarely in paratracheal scanty. The present work agrees with that Prof.Chun(1963)claimed that the affinity of this genus lies closer to the genera Michelia and Talauma macromorphologically, but so far as the wood structures are concerned,the present genus is quite similar to Michelia and less similar to Talauma.

香花木(Tsoongiodendron odorum Chun)是较近在我国发表的木兰科中的一个新的单种属——香花木属的代表。这种植物的标本远在卅年代初期即已在我省的海南和乐昌等地采得;解放后又在我省的茂名、高要、英德、仁化及乳源等地相继发现。它的树干挺直,木材细致,树冠密茂,花芬芳,不仅是细木工良好的用材,同时又是优美的行道树种;数量虽然不多,但在我省分布广,因此有推广繁殖的价值。从植物分类学的角度来看,木兰科

From 1972 to 1976, 36 species of phytophagous white grubs were found in 62 counties of the Bo-hai coastal region, of which Holotrichia oblita, Anomala corpulenta, Pentodon patruelis, H. morosa and Maladera oriental-is are dominant members. Through-laboratory rearing and field investigations it was found that H. oblita and Pentodon patruelis need two years to complete their life cycles and the winter is passed over in the larval and adult stages. Anomala corpulenta and H. morosa breed one generation each year,...

Through-laboratory rearing and field investigations it was found that H. oblita and Pentodon patruelis need two years to complete their life cycles and the winter is passed over in the larval and adult stages. Anomala corpulenta and H. morosa breed one generation each year, and the winter is passed over in the larval stage. The biological characteristics of these species have been studied and a procedure for monitoring the pest status of H. oblita has been devised.

1972—1976年间,在渤海湾沿岸62个县(区)内查出植食性蛴螬36种,其中分布广、为害重的优势种是华北大黑鳃金龟、铜绿丽金龟、阔胸犀金龟、暗黑鳃金龟、黑绒鳃金龟等。通过系统饲养和田间调查明确:华北大黑鳃金龟、阔胸犀金龟为两年一代,成、幼虫相间越冬:铜绿丽金龟、暗黑鳃金龟为一年一代,以幼虫越冬。此外还对上述四虫的一些重要的生物学特性进行了研究。根据对生活史研究,总结了“双春单秋看趋势,虫量降水定程度”的华北大黑鳃金龟发生量预测法,对于防治该虫具有一定的实际意义。
