Feeding whitefly on plant leaves, studying its growth and development, biological characteristics, host adaptability, etc., and further clarifying the interaction between whitefly and plants, is of great significance for developing sustainable control measures for such pests.

[0003] Currently, the methods for feeding whitefly on plant leaves mainly include in vitro leaf method and cage method. The in vitro leaf method is easy to operate and observe, but it uses nutrient solution to culture in vitro plant leaves to feed whitefly, ignoring the influence of normal metabolic reactions of plants on the growth and development of whitefly. The cage method, such as the one proposed in patent application No. "CN201621259777.0", includes a support, a culture solution pipe and an isolation cage.
