Plutella xylostella larvae of a strain highly resistant to spinosad were used as hosts to rear the parasitoid Cotesia plutellae. When the parasitoids had developed to the stage of early instar larva, the host larvae were treated with 50 mg/L spinosad on the terga by topical application and then fed with cabbage leaves treated with 50 mg/L spinosad to allow the host larvae and the parasitoid larvae to develop. Three days after treatment, the parasitoid larvae inside the host were collected by dissecting the host larvae. The body fluid of P. xylostella and the bodies of parasitoid larvae were then analyzed with HPLC. Both of the active components, spinosyn A and spinosyn D, of spinosad were detected in the body fluid of host larvae and in the bodies of parasitoid larvae, and the residue concentrations were 2.79 mg/L and 0.94 mg/L in the host and the parasitoid respectively.

以对多杀菌素高抗的小菜蛾Plutella xylostella幼虫作为菜蛾绒茧蜂Cotesia plutellae的寄主，待绒茧蜂发育到1龄幼虫时，将浓度为50 mg/L的多杀菌素点滴到寄主幼虫背板上，随后让寄主幼虫取食经50 mg/L多杀菌素处理过的甘蓝叶片，寄主幼虫和其体内的蜂幼虫再发育3天后，将寄主幼虫解剖取出蜂幼虫，用高效液相色谱法对经多杀菌素处理的小菜蛾幼虫体液以及绒茧蜂幼虫匀浆液进行检测，结果多杀菌素的2个活性成分spinosyn A和spinosyn D均被检测到，两者的多杀菌素残留浓度分别是2.79 mg/L和0.94 mg/L。

Tadpole-shaped parasitic larva of a trematode worm; tail ''.

蝌蚪形的吸虫类寄生幼虫；成体阶段尾巴消失。

Tadpole-shaped parasitic larva of a trematode worm; tail disappears in adult stage.

蝌蚪形的吸虫类寄生幼虫；成体阶段尾巴消失。

The result of whole mount in situ hybridization showed that MmeFer was located at the position of shell initiation in trochophore stage, indicating MmeFer plays a role in shell initiation in M. meretrix. The full-length of M. meretrix cathepsin B cDNA was cloned with 3'and 5'RACE. The temporal and spatial expressions of MmeCB mRNA were examined from trochophore to post larva stages by whole mount in situ hybridization. From L2 to L4 stages, MmeCB mRNA was detected in the digestive tract, suggesting a possible role of MmeCB in digestion.

根据构建的文蛤幼虫cDNA文库中提供的序列信息，从文蛤中克隆了与铁离子代谢密切相关的铁蛋白的全长cDNA序列；通过Real time PCR发现，MmeFer mRNA的表达量在贝壳形成前后有明显改变；整体原位杂交结果显示MmeFer mRNA在L1期的表达部位刚好是贝壳生成的起始部位，推断文蛤铁蛋白与文蛤幼虫贝壳初始形成密切相关。

Commercial fish food manufacturers do make food specifically for guppies, but even these foods seem to be incomplete. Buy a commercial food for guppies then supplement their diet with at least one of the following: brine shrimp, tubifex worms, blood worms, mosquito larva, or any other small insect or worm-like creature.
