From April 1982 to August 1985, we searched for the techniques for expermental breeding of the flea Citellophilus tesquorum sungaris Jordan, 1929. Both mixed and separate rearing methods of mixing the adults with the immature and separating them each other were used, the latter was found to be better. Fourty-six generations were bred in this period. A generation required 24 days or so, namely, the egg stage 2-3 days, the larvae stage 6-8 days, and the pupae stage 8-14 days.

From April 1982 to August 1985, we searched for the techniques for expermental breeding of the flea Citellophilus tesquorum sungaris Jordan, 1929. Both mixed and separate rearing methods of mixing the adults with the immature and separating them each other were used, the latter was found to be better. Fourty-six generations were bred in this period. A generation required 24 days or so, namely, the egg stage 2-3 days, the larvae stage 6-8 days, and the pupae stage 8-14 days. We have developed the regular and standard breeding techniques for C. t. sungaris. Quality examination results of generation breeding and regular breeding are described as follows, respectively.

我们自1982年4月至1985年8月在实验室内对方形黄鼠蚤松江亚种(Citellophilus tesquorum sungaris Jordan,1929)的养殖技术进行了系统探索。采用成幼混养和成幼分养两种方法进行养殖,共连续传代46代。养殖一代约需24天,即卵期2~3天,幼虫期6~8天,茧蛹期8~14天。同时探索了标准化和规范化的养殖方法。传代养殖和规范养殖质量测定结果分别是: 1.繁殖力:0.77±0.14只蚤/ ♀·天;1.16±0.20只蚤/ ♀·天。 2.未吸血成蚤寿命:14.3±1.0天;13.1±1.8天。 3.新羽化成蚤体重:♀为0.422±0.03mg;0.46±0.04mg,♂为0.328±0.03mg,0.35±0.03mg。 各代之间数据波动均不大,表明养殖质量稳定,技术可靠实用,在周密计划饲养下可提供规格化的实验蚤源。在国内建立了方形黄鼠蚤松江亚种的第一个规范化的实验种群。

In laboratorial conditions, the agent caused 100% mortality to the eggs, larvae and adult fleas on C.undulatus, and 90% to the pupae of the fleas, In the open-field test, pellets were exposed in the burrows, a grid encompassing 10 ha was established.

Laboratory and field tests were conducted for the control of fleas on Citellus undulatus in their various metamorphotic stages with DDVP slow-releasing pellets. In laboratorial conditions, the agent caused 100% mortality to the eggs, larvae and adult fleas on C.undulatus, and 90% to the pupae of the fleas, In the open-field test, pellets were exposed in the burrows, a grid encompassing 10 ha was established. There were significant declines in the test plots, the mean indices of fleas on the rodent, in the nests and the larva index dropped from 5.8, 46.7 and 10.2 to 2.5, 2.8 and 0.8 respectively after 43 days exposure, while in the control plots, the same indices changed from 4.1, 20.3, 7.3 to 6.8, 9.8 and 5.5 respectively, with very significant differences (P<0.01). Results indicated that DDVP slow-releasing pellets were very effective for the control of fleas on Citellecs undulatus.

以DDVP缓释剂药丸在实验室及野外对不同变态期的长尾黄鼠寄生蚤进行了杀灭试验。在实验室DDVP缓释剂药丸对长尾黄鼠寄生蚤的卵、幼虫、成蚤的杀灭率均为100%,蛹为90%;在野外,将该药丸投放于长尾黄鼠洞道中,施药面积约10公顷。施药后,体、巢蚤指数及其幼虫指数出现了明显的下降,即实验区的平均体蚤、巢蚤、幼虫指数分别由施药前的5.8、46.7、10.2下降到施药43天后的2.5、2.8、0.8;对照区的体蚤、巢蚤、幼虫指数分别由4.1、20.3、7.3上升或下降到6.8、9.8、5.5。差异均十分显著(P<0.01)。作者认为DDVP缓释剂对长尾黄鼠寄生蚤是一种行之有效的杀虫药物。

The insect growth regulator, diflubenzu- ron(TH 6040) , was tested in controlling house-fly in the laboratory.The results showed that when it was used to treating eggs of house-fly with the 0.06‰. solution the hatch-inhibiting rate was 98.7%, treating 1st and 2nd instars larvae with the same solution the killing rate was 100% in 48 h. There was no effective for 3rd instars larvae, but it can inhibite the pupal emergence.The residual activity of 0.06‰. solution of TH 6040 was determined up to 120 days, at this...

The insect growth regulator, diflubenzu- ron(TH 6040) , was tested in controlling house-fly in the laboratory.The results showed that when it was used to treating eggs of house-fly with the 0.06‰. solution the hatch-inhibiting rate was 98.7%, treating 1st and 2nd instars larvae with the same solution the killing rate was 100% in 48 h. There was no effective for 3rd instars larvae, but it can inhibite the pupal emergence.The residual activity of 0.06‰. solution of TH 6040 was determined up to 120 days, at this time the mortality of 2nd instars larvae was 100%. 3rd instars larvae was no effected, but there was no any adults emerge from the pupae. Therefor, TH 6040 was suitable for killing earlyinstars larvae of housefly, it was no effect for late 3rd instars larvae.When both sexes were fed with 0.01% solution of TH 6040 for 7 days and 10 days, none of the eggs that treated house-fly deposited had hatched.The results indicated that uninterruptedly feeding adults with 0.01% solution of TH 6040 had sterilizing action to house-fly.

本文研究了灭幼脲1号(TH6040)实验室内的灭蝇效果,0.06‰浓度对家蝇卵有杀灭效果。用该浓度处理1、2龄幼虫,48小时内死亡率为100%;对3龄幼虫无杀灭作用,但可100%地抑制蛹羽化。TH6040对2、3龄家蝇幼虫的残效,0.06‰浓度120天后对2龄幼虫的杀灭效果仍为100%;对3龄幼虫虽无杀灭作用,但可完全抑制蛹羽化。可以认为,该药不适于杀灭末龄幼虫,对于控制早龄家蝇幼虫有较好的效果。TH6040对成蝇具有不育作用,0.01%浓度药液,连续喂成蝇10天,在喂药过程中所产的全部卵均未孵化。用0.1%浓度药液喂不同性别的成蝇3天,结果证明,单独处理雌蝇或雌、雄蝇同时处理,具有不育效果;而单独处理雄蝇则无作用。
