But DNA from insect traps could yield these results in just a few months.

但是用来自昆虫诱捕器的 DNA 仅需几个月就可以收获结果。

They also could go in to find a place to hide or to feed on insects or spiders already trapped there.

它们进入猪笼草也可能是在寻找躲藏的地方或是想吃被困在猪笼草里的昆虫或蜘蛛。

The process of DNA metabarcoding starts with an environmental sample like a core of soil, a vial of water, some feces, an insect trap, or even the blood from leeches' stomachs.

在使用 DNA 复合条形码之前，我们需要收集相关环境样本。像是一份核心土壤，一小瓶水，一些排泄物，一个捕虫器，甚至是来自水蛭胃里的血液都能作为很好的样本。
