Hybrids died numerously when metamorphosing and setting on the cultch. The survival hybrid spats grow poorly with high mortality.

Results The anterior spiracle, posterior spiracle and cephalopharyngeal skeleton regularly changed with daily larval growth. The three indexes including the sclerotizes area of pharyngeal sclerite, the average optical density of pharyngeal sclerite and the posterior spiracle could be used as the ideal indexes of larvae age.

结果 丝光绿蝇幼虫前气门、后气门、头咽骨均随着时间的延长发生规律性变化，幼虫后气门平均光密度、咽骨骨化面积及其平均光密度这3项指标是推断幼虫日龄较理想的指标。

objective to isolate and purify the antimicrobial peptides with anti-toxoplasma gondii activity isolated from the haemlymph of musca domestica larvae.methods the antimicrobial peptides of musca domestica larvae were induced by infection and injury were isolated and purified by trituration,centrifugalization and column chromatography.then the antimicrobial peptides with anti-toxoplasma activity were sieved by mtt colorimetric method and haemacytometry.results it was found that two antimicrobial peptides had anti-toxoplasma activity through resource s cationic column chromatography and superdex g75 gel column chromatography.conclusion the two antimicrobial peptides with anti-toxoplasma activity existing in the haemlymph of musca domestica larvae had different anti-toxoplasma effect.

作者单位：山西医科大学寄生虫教研室，太原 030001；化学生物学与分子工程教育部重点实验室山西大学生物技术研究所目的从家蝇幼虫血淋巴中分离纯化具有抗弓形虫作用的抗菌肽。方法通过损伤加感染的方法诱导家蝇幼虫大量表达抗菌肽，然后经过研磨、离心和层析等过程，将家蝇幼虫抗菌肽进行分离纯化，采用四甲基偶氮噻唑蓝比色法和血细胞计数法筛选对弓形虫速殖子有抑制作用的抗菌肽。结果经resource s阳离子柱和superdex g75凝胶柱层析后，筛选出2种对弓形虫速殖子有杀伤作用的抗菌肽。结论家蝇幼虫血淋巴中存在抗弓形虫作用的抗菌肽，而且不止一种，但其效果有所不同。

Red ants carry the larvae into their nests, where they live for the next 10 months feeding on ant grubs, until they pupate and emerge as adults.

幼虫掉在地上，接着就是最奇怪的地方，红蚁把其幼虫扛进巢穴中，在那里它们要呆10个月，靠蚁幼虫为生，直到它们化蛹，成为成虫。

The bioassay resultshowed the three kinds of PG tested could prolong the duration of larval stadium.Salicortin and deltoidin could reduce the survival rate of larvae,pupate rate andgrowth weight evidently,especially for salicortin at high lever(more than 2%).

结果表明，3种酚甙对幼虫生长发育均存在不同程度的负作用，并有剂量效应；3种酚甙均可延长幼虫虫期；柳皮甙和美洲黑杨甙可明显降低幼虫存活率、体重增加率和化蛹率；尤其是柳皮甙在高含量条件下(大于2％)作用更为明显。

The honeybee spawns in the nest room, the larva lives in the nest room, the camp society sex life larva by the worker bee oral administration, the camp roosts the sex life the larva to take the food female bee alone to store in Yu Chaoshi the bee grain, waits the bee grain to be fed up, larva mature pupation, when emergence broken cocoon.

蜜蜂在巢室内产卵，幼虫在巢室中生活，营社会性生活的幼虫由工蜂喂食，营独栖性生活的幼虫取食雌蜂贮存于巢室内的蜂粮，待蜂粮吃尽，幼虫成熟化蛹，羽化时破茧而出。

Experiment results showed as follows: 1 Two kinds of reactive oxygen species exhibited remarkable damage to larvae on 3 types of different development stage.The treatment of reactive oxygen species could result in decrease of larva survival rate and inhibit metamorphosis rate of cyprid.

实验结果表明：1、二种类型的活性氧对东方小藤壶三种不同发育时期的幼虫均具有伤害作用，在其作用下，幼虫存活率的下降，变态过程受到抑制，且表现出一定的剂量效应；三种不同发育时期的幼虫对活性氧作用的敏感性存有明显的差异性，Ⅵ期无节幼虫对羟自由基的作用最为敏感。
