Rice planthopper honey dew amount measuring device and using method thereof

Abstract

The invention relates to a rice planthopper honey dew amount measuring device and a using method thereof. The device comprises a culture container, a bearing partition plate which covers an upper endport of the culture container and a feeding container of which a lower port covers the bearing partition plate, and a cultivation tube for accommodating a rice nutrient solution and the roots of ricestems is fixed in the middle of the inner bottom surface of the culture container; a connecting tube for connecting the culture container and the feeding container penetrates through the middle of thebearing partition plate, the connecting tube provides convenience for the upper ends of the rice stems to penetrate though, the top surface of the bearing partition plate is provided with qualitativefilter paper for bearing honey dew secreted by rice planthoppers after feeding, and a worm hole is formed in the middle of the top surface of the feeding container. The device has simple structure and convenient manufacture and use, can rapidly, accurately and effectively measure the amount of the honey dew released by the rice planthoppers, and can also be used as a rice planthopper breeding andbiological observation device.

Description

Technical field: [0001] The invention relates to a rice planthopper honeydew measuring device and a using method thereof. Background technique: [0002] Rice planthopper is an important pest in rice grain production, especially the brown planthopper is one of the most important pests of rice. When the brown planthopper breaks out, it often causes rice treading, resulting in a reduction in rice production and often causing major economic losses. one of the major threats. In recent years, with the change of global climate and environment and other factors, the popularization and application of a large number of new insect-susceptible rice varieties, and the large-scale use of pesticides and fertilizers, etc., frequent outbreaks of rice planthoppers have caused disasters, especially the outbreaks of brown planthoppers. Disasters often cause serious economic losses. For example, the rice brown planthopper outbreak in the Yangtze River Basin in 2005 caused extremely heavy econom...

Problems solved by technology

Through practice, it is found that the two methods for measuring the honeydew amount of rice planthoppers have defects or deficiencies, and the main defect of the first method is that the roots of rice plants are treated with cotton or sponge to keep moisture, which cannot guarantee the quality of each rice variety test or the same rice variety. During repeated experiments, the amount of liquid contacted by the roots of the rice plants was exactly the same, and this method of treating the rice plants could not guarantee that the rice plants could remain upright, which would easily cause the rice plants to tilt, which would affect the feeding activities of rice planthoppers and would inevitably affect The amount of honeydew in the rice planthopper, which leads to the incomparability of the test results. In addition, only the filter paper is used to separate the two plastic cups. Since the filter paper cannot guarantee enough strength to support the plastic cup used as the feeding room, it is easy to cause the plastic in the feeding room. The cup was dumped, causing the test to fail, and the filter paper is likely to affect the accuracy of the measurement results due to moisture absorption due to contact with the rice plant

The main defect of the second measurement method is that on the one hand, the installation of the parafilm film pouch on the rice plant may affect the accuracy of the test measurement results due to the adsorption of water on the surface of the rice plant on the film; It is not simple enough, and some small holes need to be pierced on the parafilm pouch to keep the feeding room ventilated. In addition, it takes a long time to move the rice planthopper into the parafilm pouch, the operation is cumbersome, and the work efficiency is low.
