It was shown that peroral infection of the larvae with mixture of GP37 and SpltMNPV could not obtained the significant difference from that only with virus. The GP37, however, was fed to the cotton leafworm larvae 30h in advance of virus infection, resulting in around 50% reduction in larvae mortality.

GP37抗体结合实验结果显示,用GP37抗体与病毒粒子结合后感染斜纹夜蛾幼虫,幼虫的死亡率与对照组没有显著差异,证实了GP37蛋白不是存在于病毒粒子外膜上的蛋白或者不是受体结合蛋白。

Resistance. The results indicated that larval mortality of the transgenic cottons on the insect of the second instar feeding with Zhongmiansuo 41 was significant higher than on Zhongmiansuo 23, and the mortality of the rest of instar larvae, the period of larvae,the pupate rate of larvae and the rate of larva developed into moth of S.litura hadno significant difference compared with control.

室内应用中棉所 45 、中棉所 41 两种转双价基因棉品种与对照品种中棉所 23 的顶端展开的第 4 张叶片,分别饲喂斜纹夜蛾 Spodoptera litura 幼虫,考察对幼虫、蛹、成虫的影响,编制并分析实验种群生命表,明确上述两种转双价基因棉对斜纹夜蛾的抗性作用。

Although those DAPs were also found in the hemolymph of non-diapausing larvae, they had higher titer in the hemolymph of diapausing larvae than in the hemolymph of nondiapausing larvae.

虽然它们在非滞育幼虫血淋巴中也存在,但是它们在滞育幼虫血淋巴中的含量明显高于在非滞育幼虫血淋巴中的含量。

The test results of acute toxicity were examined with Pearson's degree of fitting. The results indicated that the silkworm was extremely sensitive to Chlorantraniliprole. The median lethal concentration (LC50) was 4.0905×10^(-3) mg/L and median lethal dose (LD50) was 1.1435×10^(-8) mg/larva for the 3rd instar newly exuviated larvae. No toxicity was observed when normal concentrations of Chlorantraniliprole were used to fumigate the silkworm rearing room. Both irrigation and leaf spraying with 1.25×10^(-4) mg/L Chlorantraniliprole solution showed strong systemic transmission properties in root, leaf and whole plant. The residual toxic period of this insecticide to silkworm was very long. Mulberry leaves sprayed with 1.25×10^(-4) mg/L Chlorantraniliprole solution could still cause 100% mortality of the 3 and 5 instar larvae after 60 d. Furthermore, toxic reaction was very quick. The poisoning symptoms emerged within 1~5 h after feeding on the poisonous leaves. The poisoned larvae experienced such symptoms as stopping ingestion, remaining still, vomiting slightly and body atrophy sequentially, and died ultimately.

食下毒力试验结果经Pearson拟合度检验表明,氯虫苯甲酰胺对3龄起蚕的食下致死中浓度(LC50)为4.0905×10^(-3)mg/L,致死中量(LD50)为1.1435×10^(-8)mg/头;药剂在常规浓度下对家蚕无熏蒸毒性;1.25×10^(-4)mg/L稀释药液对桑树根灌和喷叶处理,表现极强的根部、叶部和全株性内吸传导特性;药液对家蚕的残毒期很长,1.25×10^(-4)mg/L稀释药液田间喷雾桑叶,间隔60 d后采叶饲喂3龄和5龄蚕的死亡率均为100%,且中毒反应极快,添食毒叶后1~5 h出现中毒症状,经停止食桑、静伏、少量吐液、蚕体萎缩等过程后陆续死亡。

In spring 2004, diseased Maruca vitrata larvae were found in Sesbnia cannabina, a leguminous green manure crop grown all over Taiwan in summer season. The infected larvae became sluggish, pinkish, ceased feeding, body became fragile and ruptured; dead larvae were hanging on the top of plant with prolegs attached to the host plant, that is a typical symptom of nudeopolyherosis.

在2004年的春天,实验室在夏季遍及台湾种植季节的豆科绿肥的田菁里观察到染病的豆荚螟幼虫,染病的幼虫变得呆滞,体色稍呈现粉红色,停止进食,身体变得脆弱易破裂,死亡的幼虫被发现附著在寄主植物的顶端悬挂著,这显示是被杆状病毒感染的徵状。

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。
