The biological safety of Bacillus thuringiensis Strain YJ-2000 which acted the low toxicity to Bombyx mori newly hatched larvae and marked insecticidal activity to other lepidopterous insects was evaluated compared with other two Bt strains,i.e.

YJ 2 0 0 0菌株除导致 1龄幼虫历期延长 11 1%、取食量减少 0～ 6 0 0 %及体重降低 5 2 3%～ 6 2 5 %外，对 2龄及其以后各龄幼虫的存活率、发育历期、取食量、眠蚕体重、化蛹率、蛹期、全茧量、蛹重、茧层量、羽化率和产卵量等均无显著影响。

The spawning area was successfully outlined to the west of the Mariana Islands in 1991, and other research suggests that their recruitment success may be related to El Nino events, which appear to affect the transfer of leptocephali from the north equatorial current into the Kuroshio Current.

From otoliths, the spawning times of these three species are all estimated to occur much later in the year than when small leptocephali are found at sea, indicating that ages appear to be underestimated.

从耳石来看，这三种鳗的产卵时间按照耳石推断出来都比实际发现柳叶鳗的时间要晚一些。

European eels are inferred to spawn year-round from otolith analysis, but the smallest, recently hatched leptocephali are found only in late winter and spring.

From May to October 2005 and May to August 2006, 671 specimens collected were used for studies on the reproductive strategies such as reproduction time, spawning type, the ratio and the fecundity, and gonad development and characters of early life history. The main results are as follows: 1.Every year speaking of spawning season the male"s is earlier than female"s slightly.

Nov。仅分布于宝兴河支流东河盐井以上河段，主要分布在蚂蝗沟、嘎日沟、波日沟、和平水域及邓池沟，属于分布区极其狭窄的种类。2005年5月—10月和2006年5月—8月共采集671尾标本，运用常规生物学指标的测定分析法和性腺的组织切片法，以及对成熟亲鱼人工授精获得的胚胎在立体显微镜下活体观察，研究其繁殖期、产卵类型、性比和繁殖力等繁殖策略及性腺发育和早期发育。

Dorsalis could be easily dyed by the specific dyes on different fruit species, methyl blue, basic red and congo red showed the best dyeing effect for Mangifera indica, Psidium guajava and Citrus sinensis respectively, 0.5% was the best concentration for dyeing.

筛选出甲基蓝、藏红和刚果红作为芒果、番石榴和夏橙的最适染色剂，各种染色剂在浓度为0.5%时染色效果较佳，同时对持续冷藏保存后的水果上的产卵孔仍然具有较高的染色率。

Essential oil of Mentha spicata was also active, with ODR and ODR, of 89.19% and 73.3%, respectively.

留兰香油对荔枝蒂蛀虫也有较好的产卵驱避效果，其ODR和ODR分别为89.19%和73.30%。
