Synergy of Recombinant Enhancin of Trichoplusia ni Granulovirus;2. The synergy of honey and cabbage filtrate on Autographa Californica nuclear polyhedrosis virus and Bacillus thringiensis against the larvae of plus agnate was studied.

室内以蜂蜜和新鲜小白菜汁分别添饲银纹夜蛾幼虫，测定了其对AcNPV和Bt的增效作用，结果表明：在中低浓度AcNPV时，蜂蜜和新鲜小白菜汁液刺激银纹夜蛾幼虫初期取食，其感染后前3 d的粪便量比只有AcNPV处理的增加34。

the development period of over-wintering larvae of three voltinisms asian corn borer in langfang,hengshui,fuxin,gongzhuling,shuangyashan,haerbin from resuscitation to pupation was studied. the results showed that the development period was different among the different voltinism groups,and it was same within the same voltinism groups.

通过对廊坊、衡水、阜新、公主岭、双鸭山和哈尔滨6个地区3种化性的玉米螟越冬幼虫复苏后发育至化蛹历期的研究，得出3种不同化性种群间的玉米螟幼虫复苏后发育至化蛹的历期有明显差异，而相同化性种群间的玉米螟幼虫复苏后发育至化蛹的历期无明显差异。

The assay of the coarse protein , a variety of amino acid about nematode-trapping fungus — Arthrobotrys oligospora strain A1 and the third stage larva showed that the contents of the coarse protein and a variety of amino acid of larva are mostly higher than that of predacious organs containing annulus and cohesive net ,conidia and hypha in the different growth phases.

捕食线虫性真菌——少孢节丛孢菌菌株及线虫第三期幼虫的粗蛋白质和各种氨基酸种类及其含量化学成份测定结果表明：捕食线虫性真菌—少孢节丛孢菌的各生长阶段和线虫幼虫的粗蛋白质和氨基酸的种类和含量比较显示：线虫幼虫的粗蛋白质和各种氨基酸的含量大多数都高于少孢节丛孢菌捕食器、分生孢子、和菌丝的含量；结果还说明：捕食器菌丝的化学组成也与普通菌丝不一样。

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。

After treatment with chlorfluazuron to the larvae, the activities of POD in the larvae of three instars were all higher than the control, while the activities of POD in the second and third instar were only 65.0% and 99.2% of those in the control.

抑太保处理后，过氧化物酶活力除2龄幼虫在处理后5 h下降，仅为对照的65.0%，3龄幼虫在处理后1 h为对照的99.2%外，3个虫龄幼虫的POD活力均高于对照。H2O2由0增加至0.1 mL，POD活力呈线性关系上升。

Then the number of larvae in the stem increased sharply for a great number of newly-hatched larvae appeared. Though some larvae transferred from stem to root before overwintering, about 43% of the larvae overwintered in tree stems at the height between 40 and 120 cm in the end of September till after the overwintering the next year.

之后，由于初孵幼虫的大量出现，使干部幼虫数量急剧增加，越冬前，虽然有部分转移至根部危害，但到9月末仍有近43%的幼虫停留在树干40～120cm处越冬，直到次年越冬结束。

Pallidifascia were studied by indoor and outdoor trials. The results showed that the pest developed 4 generations a year and overwintered with larvae in Guangzhou, Guangdong province of China. The larva stage included 7 instars. It appeared sexual dimorphism on the adults. The egg, larva and pupa stages lasted 4-5 days, 32-34 days and 9-11 days at 26℃ respectively.

采用室内外养虫及林间调查相结合的方法观察木荷空舟蛾的生物学特性，观察结果如下：在广州1年可发生4代，以幼虫在土中越冬，幼虫分7龄，成虫有性二型现象；在26℃时，卵期4-5天，幼虫期32-34天，蛹期9-11天。

The larvae on different development stage indicated different sensitivity to reactive oxygen species, the napuli VI showed the most sensitive. 2 Antioxidants could decrease the damage effect of reactive oxygen species on larvae in certain level.The addition of antioxidants in culture system had risen larva suvival rate and the metamorphosis rate of cyprid .

外源抗氧化剂的加入在一定程度上减弱了活性氧对东方小藤壶幼虫的伤害作用，从而提高了幼虫的存活率和变态率；在减弱活性氧对东方小藤壶幼虫的伤害作用中，不同类型的抗氧化剂对不同类型的活性氧所起的作用大小不同。

Cantly greater numbers of living larvae were found in sugar maple than in the other tree species; however,more were found in red oak and fewer in green ash than expected,considering relative numbers of oviposition sites. After 90 d,mean mass of living larvae did not differ signi?cantly among tree species.

然而，考虑到产卵点的相关数量，我们在红橡树上发现的活的幼虫的量要比预料的多，而在白蜡树上发现的幼虫的量则没有预料的多。90天后，在这些树种上平均幼虫总量已经没有显著的差异了。

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 this paper, the requirement analysis, design and implementation of the system are introduced in detail.

此论文详细介绍了系统的需求分析，系统设计和具体实现。
