The antiparasitic effect of caprylic acid against several fish parasites, i.e., the ciliate Cryptocaryon irritans, monogenean Benedenia seriolae, copepod Pseudocaligus fugu and myxosporean Kudoa shiomitsui, was examined by in vitro trials.Caprylic acid at a concentration of 1 mM had a parasiticidal effect against C. irritans theronts, B. seriolae oncomiracidia and K. shiomitsui spores and a contractile effect against B. seriolae adults, but had no clear effect against P. fugu copepodids and adults.

Although the 24 hour-hatching rate of Artemia nauplii (30±1%) was significantly lower than untreated group (61±7%), the GFP expression rate was 33±6% in 72 hours after hatching.

虽然丰年虾无节幼虫於24小时后的孵化率(30±1%)显著地低於未经处理的对照组(61±7%),但於孵化后72小时的绿萤光表现率为33±6%。

In order to investigate the relationship between lipid raft and the formation of membrane pore by Bt β-endotoxins, the preparation and identification of lipid raft from the larval midgut of Helicoverpa armigera was performed.

为研究脂筏与Bt毒素在细胞膜上形成寡聚体膜孔的关系,本文对棉铃虫Helicoverpa armigera幼虫中肠脂筏的制备与鉴定方法进行了研究。

In certain range,the bioenrichment of the mealworm larvae to Zinc in reference to the dosage added in the fodder is accorded with cubic curve relation:Y=181.2517+20.9314X-0.4099X2+ 0.0025X3. And the enrichment ability of T. molitor larvae in reference to the weight is also accorded with the cubic model:Y=35.8325+61.4155X-10.2980X2+0.4434X3. The enrichment of the larvae to Zinc can get to a high level in 2 to 3 days. This is anadvantage to numerous rearing of the mealworm. But we do not find a good rearing way to enhance the rate of bioenrichment to Zinc. And the further research about this is anticipated.

第二部分:采用锌作为添加元素,考查黄粉虫对微量元素的富集规律,结果表明:(1)黄粉虫虫体锌含量在一定范围内随锌添加量增加而呈三次曲线关系,符合三次曲线方程:Y=181.2517+20.9314X-0.4099X~2+0.0025X~3;(2)黄粉虫幼虫对锌富集能力随虫体大小变化而变化,与虫大小亦呈三次曲线关系;Y=35.8325+61.4155X-10.2980X~2+0.4434X~3;(3)黄粉虫虫体锌含量随着锌饲料添加而迅速上升,可在短期2~3天内达到较高水平,对于以黄粉虫为材料进行富锌保健食品生产有很大优越性;(4)本试验并未找到一种较好的锌添加方法来提高锌富集量,这方面的研究有待继续。
