Method for monitoring activity area of winged adult termites

Abstract

The invention discloses a method for monitoring activity area of winged adult termites. The method comprises the following steps of selecting to-be-investigated termite colonies 2-3 weeks in advance under the meteorological condition of termite swarming; under the circumstance that a large number of winged adult termites come out from swarming exit holes, spraying red or green fluorescent powder onto the wings of the adult termites; in the forenoon of the next day, selecting sample areas at near light source locations within 1500m on the periphery of the swarming exit holes; collecting the wings of all termites which can be seen in the sample areas; recording the locations of collection points; drying the wings of the termites; detecting whether each wing of the termites is sprayed with the corresponding fluorescent powder or not by using a fluorescence microscope; measuring a distance from each collection point at which the wings of the termites with the fluorescent powder are collected to the swarming exit hole so as to judge the activity area of the winged adult termites. According to the method for monitoring the activity area of the winged adult termites, the data about the activity area of the winged adult termites are more precise and further approach the reality, which has important significances in implementing termite prevention and treatment and determining a prevention and treatment area.

Description

Technical field: [0001] The invention relates to the field of insect control, in particular to a method for monitoring the activity range of termite winged adults. Background technique: [0002] Termites are one of the most important pests in the world. It is of great significance to study the range of activities of termite winged adults for the development of termite control and the formulation of its control range. At present, there are not many studies on the activity range of termite winged adults. Forschler (1994) used fluorescent spray paint to mark three species of worker ants of Reticulitermes flavipes, R.virginicus and R.hageni of the genus Reticutermes, and used a hand-held ultraviolet lamp UV-4B to detect the activity range of worker ants. The fluorescent marking materials usually used are Fluorescent spray paint, containing film-forming substances (grease, resin, etc.), additives (defoamers, leveling agents, etc.), pigments and solvents (hydrocarbon solvents, al...

Problems solved by technology

Forschler (1994) used fluorescent spray paint to mark three species of worker ants of Reticulitermes flavipes, R.virginicus and R.hageni of the genus Reticutermes, and used a hand-held ultraviolet lamp UV-4B to detect the activity range of worker ants. The fluorescent marking materials usually used are Fluorescent spray paint, containing film-forming substances (grease, resin, etc.), additives (defoamers, leveling agents, etc.), pigments and solvents (hydrocarbon solvents, alcohols, ethers, ketones and esters), During use, it is found that the film-forming substances and solvents used will cause the wings to wrinkle. At the same time, it is also found that it will also have a potential poisonous effect on termites, affecting the flight distance and range of activities of termites. Therefore, it is impossible to understand the real activity of termites, which is not conducive to The study of termite ecology; in addition, when detecting termite adults with a hand-held ultraviolet lamp, more markers on the wings are required to effectively detect, but when the amount of markers increases, the impact on the flight of termite adults also increases. As it increases, it also affects its normal activities, resulting in inaccurate observation data
