Studies of insect feeding behavior are useful in different areas of entomology such as plant resistance, biology, and insecticide efficacy. For chewing insects, this kind of technique is well established, but for sap-sucking insects, especially tiny ones such as whiteflies, aphids, and psyllids, these tests can be laborious. Manipulation is difficult and can damage the plant, affecting the results. We describe here three types of cages for tests with small insects, one for seedlings in pots, a second for larger plants or plants in the field, and a third for caging insects on part of a leaf. These cages have been useful for different types of studies in addition to feeding behavior and can facilitate research with small phytophagous sucking insects.

昆虫取食行为的研究在昆虫学的不同领域很有用，例如植物抗性、生物学和杀虫剂功效。对于咀嚼昆虫，这种技术已经成熟，但对于吸液昆虫，尤其是粉虱、蚜虫和木虱等微小昆虫，这些测试可能很费力。操作很困难，可能会损坏植物，影响结果。我们在这里描述了三种类型的笼子，用于测试小昆虫，一种用于盆中的幼苗，第二种用于较大的植物或田间植物，第三种用于将昆虫关在部分叶子上。除了喂养行为外，这些笼子还可用于不同类型的研究，并可促进对小型植食性吸吮昆虫的研究。
