A Simple Device and Measurement Method for Measuring the Adhesive Force of Tiny Insects and Liquid

Abstract

The invention relates a simple device for measuring adhesive force of small insects and liquid. The simple device comprises an inverted-T-shaped support, the upper end of the support is hinged to the middle of a transversely-arranged lever, pointers are arranged at the two ends of the lever, length-adjustable cotton threads are tied at the two ends of the lever, coils are tied at the lower ends of the cotton threads, and a gold wire for hanging the insects is hung on the coil on the right side. A dial on the left side of the pointer at the left end of the lever and a vessel which is arranged below the gold wire and used for containing the liquid are further included, and the zero graduation line in the center of the dial is flush with the lever. A plurality of small gold wires equal in length used as weights are further included. Meanwhile, a measuring method for measuring the adhesive force of the small insects and the liquid is provided. Manufacturing cost is low, material resources are convenient to find, and the simple device and measuring method are suitable for measuring small force. Measurement precision is high. Good repeatability is achieved, and meanwhile the measuring method is simple and easy to implement.

Description

Technical field [0001] The invention relates to a simple device for measuring the adhesion of tiny insects and liquids and a measuring method thereof. Background technique [0002] At present, important agricultural pests are becoming more and more miniaturized, such as aphids, whiteflies, planthoppers and leafhoppers. These tiny insects are relatively small, and there are few reports on their behavior. At present, the research on the adhesion of insects (wings, skins, or feet) to liquids (such as water, etc.) is mainly focused on the research and development of insect bionic materials, and the main selection of insects in this area is medium and large insects, often missing tiny insects. Hydrophobic properties. On the other hand, few studies have focused on the impact of natural water stress (precipitation or dew) on important agricultural pests. There are reports that tiny insects are easily affected by precipitation, but research on its mechanism is rarely reported. Therefor...

On the other hand, few studies have focused on the impact of agriculturally important pests on natural water stress (precipitation or dew)

It has been reported that the population of tiny insects is easily affected by precipitation, but there are rare reports on its mechanism. Therefore, it is very necessary to design a device for measuring the adhesion of tiny insects to liquids. By measuring the adhesion of tiny insects to water , can detect the influence of water on these agricultural pests, and will also provide convenient conditions for the research of insect biomimetic materials to develop into tiny insects
