Dibrachys cavus (Walker) is an ectoparasite of the cotton pink bollworm. It pro-duces 11--12 generations annually at Hangchow, Chekiang Province. It overwintersmainly in the larval stage within the cocoon of the parasitized overwintering cotton pinkbollworm. A maximun of 21, a minimun of 1, and an average of 10.67 hosts is parasi-tized by a single female. The average number of the offspring is 100.47, but when theparasite could not find sufficient hosts for oviposition, the number of the offspringrapidly decreased....

Dibrachys cavus (Walker) is an ectoparasite of the cotton pink bollworm. It pro-duces 11--12 generations annually at Hangchow, Chekiang Province. It overwintersmainly in the larval stage within the cocoon of the parasitized overwintering cotton pinkbollworm. A maximun of 21, a minimun of 1, and an average of 10.67 hosts is parasi-tized by a single female. The average number of the offspring is 100.47, but when theparasite could not find sufficient hosts for oviposition, the number of the offspringrapidly decreased. The sex ratio of D. cavus is usually 80--90%. This species can re-produce parthenogenically, and individuals developed from the unfertilized eggs are allmales. The longevity of an adult varies according to sex and temperature. Under labo-ratory conditions, it was found that those adult parasites supplied with honey or hosts sur-vived longer than those without such. The egg stage lasts 2--5 days, the larval stagegenerally lasts 5--14 days, while the overwintering larval stage lasts 141--145 days, andthe pupal stage generally 5--35 days. A list of 148 host species (including subspecies) in 36 families, representing 6 orders,reported by other authors is given. In the laboratory D. cavus also attacked and com-pleted its development on Anchonoma xeraula Meyrick, Pristomerus chinensis Ashm. andan undetermined species of Apanteles, the last two being primary parasites of the cottonpink bollworm. It is easy to rear the parasite. A simple and inexpensive method of large-scaleproduction is reported. In April of 1961, over 1.16 million parasites were released tomore than 200 cotton warehouses in the villages of Siaoshan district. The average per-centage of parasitism in the colonized warehouses was more than two times that of theuntreated warehouses (check). In the check warehouses the average percentage of livingcotton pink bollworm was 19.32%, while that in the colonized warehouses was 0.86%. The overwintering cotton pink bollworm may be induced to spin its cocoon in thesandy loam and cocoons so formed are also suitable for rearing the parasite. It may bea desirable method for overcoming the difficulty of collecting the host in large numbers.The writer has kept the larvae of the parasite in a refrigerator at 0--10℃ for a periodof 64 days, and found them pupating and emerging normally after removal from the re-frigerator. These adults were normal with respect to longevity, capacity of parasitismand reproduction. But when the larvae of the parasite were kept too long in the re-frigerator (e.g., 300 days), they were severely impaired in longevity, capacity of parasi-tism and reproduction of adults. The succeeding generation from such larvae appearedto be nearly normal in vitality. The result of a preliminary comparison test showedthat the race of the parasite collected from Kiukiang, Hangchow or Yungtzi is better thanthat from Yuncheng. It was found possible to increase vitality of this parasite bybybridization with different races from distant localities. D. cavus may be a beneficialparasite or undesirable one depending on whether the hosts present are harmful or useful,a fact to be kept in view before starting to make use of this parasite. In the writer'sopinion, this parasite seems to be harmless when used for combating the overwinteringcotton pink bollworm.

黑青小蜂系棉红铃虫的外寄生蜂。在杭州,年发生11代,少数12代。主要以幼虫在越冬红铃虫的茧内越冬。每雌平均寄生红铃虫10.67头,产子蜂100.47头。若寄主供应不充分,则子蜂数量显著减少。性比高,通常为80-90%。成虫寿命与温度关系密切,雌蜂一般长于雄蜂。喂以蜂蜜或给以寄主供其寄生,寿命均能显著延长。卵期2—5天;非越冬幼虫历期5—14天,越冬幼虫历期141—145天;非越冬蛹历期5—35天。 综合文献记载,已知寄主6目36科148种(包括亚种)。经室内试验,能顺利地寄生并育出子蜂的,尚有米淡墨虫、中国齿腿瘦姬蜂以及一种绒茧蜂。后二者均为红铃虫的寄生蜂。 此蜂易于饲养,采取一系列简易的办法,能顺利地进行大量繁殖。在二百余棉仓放蜂116万余头的结果,对活红铃虫的寄生率自33.61%提高至95.93%,增高1.85倍,红铃虫活虫率则自19.32%降至0.86%,抑低95.55%。 越冬红铃虫能在沙土中作茧;所结之茧,此蜂同样寄生、发育并羽化,可望通过这一途径,改进繁殖用寄主的采集方法,以节约劳力。幼虫于5℃上下、0—10℃范围内冷藏64天后表现仍正常,但长期冷藏则生活力大受影响,而繁殖一代后又显然有所恢复。各...

It is said that Pinus massoniana Lamb, which growing in the Kwangtung province is of two forms, i.e., one possessing more resin and the other with less resin. In the present paper, both the wood structure and the physico-mechanical properties of the two form timbers which were collected from the northern part of the province have been preliminarily studied. They are about thirty years old. According to the wood anatomical characteristics, these forms may be distinguished as follows: the first form comparing with the second form has wider ring-width, lower late-wood percentage, thinner tracheid-wall thickness and larger lumen-width, shorter tracheid-length, more rays and more radial resin ducts, less in numbers of tangential wall pits on late-wood tracheids, shallowly dentate ray tracheids, and more window-like pits per cross-field. Above all, the ring width and the tracheid length are the salient features. Among the physico-mechanical properties of the two forms of timbers, only both the strength in tension parallel to the grain and the shearing strength parallel to the grain have reliable differences. Moreover, the strength index, the strength/weight ratio and the height-growth rate are higher in the second form than which in the first one. In comparison with the race from other localities, the Masson pine timbers grown in the northern part of Kwangtung are the strongest in the main strength properties.

本文初步研究粤北乐昌大源林区近30年生馬尾松两个变型——“油松”和“糠松”的木材构造和物理力学性貭。依照木材解剖特征,将两个变型区别如次:油松的輪寬較大,晚材率較小,管胞壁厚稍小而腔闊稍大,管胞长度較短,木射线略多与径向树脂道較多,此外軸向管胞切向壁上具緣紋孔数目較少,射线管胞內壁鋸齿发育程度較浅,交叉場紋孔数目略多;糠松則相反。两者的主要差异为輪寬与管胞长度。油松与糠松两者的木材物理力学性貭,仅順紋拉力和順紋剪力有可靠的差异。此外,后者具有稍高的强度指标、貭量系数以及較大的树高生长。又粤北馬尾松木材的貭量系数,远胜他地同种松木,其主要力学指标較高,生长較快。

(3)pectoral fin rays. (4) pyloric caeca. (5) the vertebrae. (6) fused pre-caudalhaemal spines. (7) post-cranial vertibrae with multiple neural spines. (8) de-gree of completeness of second anal pterygiophore. (9) the borny tubercle. (10)the parasites in abdominal cavity, and (11) the shape of the swim-bladder.Altogether 2232 samples in 24 lots were collected for ananalyses from theYellow Sea and Pohai, the East China Sea, the South China Sea, and the Gulfof Tongking. In addition, two lots of mixed samples and three lots of larvae ofthe same-year class have also been analized. The results obtained during the studies demonstrated that the hairtails maybe grouped into five local races, viz., (1) the Yellow Sea-Pohai race. (2) therace of the East China Sea-Eastern coast of Kwantung. (3) race of Westerncoast of Kwantung. (4) the race of coastal waters of the Gulf of Tongking. (5)the race offshore waters of the Gulf of Tongking. It is noticed that the first two races differ considerably from the otherthe three (Table 7).
