Example Embodiment

[0012] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following will further describe the present invention in detail through specific embodiments and related drawings.

[0013] Such as figure 1 As shown, a simple device for measuring the adhesion of tiny insects to liquids includes an inverted T-shaped bracket 1. The upper end of the bracket 1 is hinged with the middle of a horizontal lever 2. The length of the lever 2 is about 12 cm. There is a pointer 9 at the end, a cotton thread 4 with adjustable length is tied at both ends of the lever 2, a coil 5 is tied at the lower end of the cotton thread 4, and a gold wire 6 for hanging insects 7 is hung on the coil 5 on the right; It includes a dial 10 on the left side of the pointer at the left end of the lever 2 and a vessel 11 for liquid under the gold wire 6. The measured liquid in the vessel 11 can be diversified, such as distilled water, vegetable oil, acetone, etc., th...

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 and a measuring method for measuring the adhesion force between tiny insects and liquid. Background technique [0002] At present, important agricultural pests are becoming more and more miniaturized, such as aphids, whiteflies, planthoppers, and leafhoppers. Due to their small size, there are few research reports on their behavior. At present, the research on the adhesion between insects (wings, skin, or feet) and liquids (such as water, etc.) mainly focuses on the research and development of insect bionic materials, and the insects in this area are mainly medium and large insects, and the small insects are often missed. Hydrophobic properties. On the other hand, few studies have focused on the effects of natural water stress (precipitation or dew) on agriculturally important pests. It has been reported that the population of tiny insects is easily affected by precipitation, but there are rare reports on its ...
