CN-122004224-A - Application of 2-acetylfuran in aphid prevention and control and regulator

Abstract

The invention belongs to the technical field of green prevention and control of agricultural pests, and particularly relates to a aphid prevention and control and regulation agent. The key point is that the 2-acetyl furan is used for controlling aphids. The 2-acetyl furan provided by the invention has obvious concentration-dependent behavior regulation effect on aphids, and can select different concentrations according to control requirements, so that double behavior regulation on myzus persicae is realized.

Description

Application of 2-acetylfuran in aphid prevention and control and regulator Technical Field The invention belongs to the technical field of green prevention and control of agricultural pests, and particularly relates to a aphid prevention and control and regulation agent. Background Aphids are an important pest group in agricultural production, and can be directly pricked to cause harm or indirectly cause harm by transmitting viruses. The Myzus persicae is a pest distributed worldwide, mainly harmful to tobacco, cabbage, rape, radish, peach tree and other crops, and can also transmit various plant virus diseases such as potato virus Y, cucumber mosaic virus and the like, thus causing serious loss to agricultural production. In production practice, chemical pesticides such as imidacloprid, acetamiprid, thiamethoxam and the like are sprayed to control the myzus persicae. However, the use of pesticides in large quantities is easy to cause the problems of rising of drug resistance of pests, environmental pollution and the like. Therefore, development of a green prevention and control technology based on pest behavior control is urgently needed to reduce the use of chemical pesticides and protect the ecological environment. CN104557808a has disclosed that 2-acetylfuran has fumigating, contact killing and repellent activity against coleopteran pests, namely tobacco a and red-hogwash in tobacco warehouses, and is used as a botanical pesticide for tobacco warehouse empty warehouse spraying or fumigating. However, the biological activity of the compound against aphids in the hemiptera has not been reported nor is it disclosed whether it has a modulating effect. Disclosure of Invention The invention aims to provide an application of 2-acetyl furan in controlling myzus persicae, wherein the 2-acetyl furan is used for preparing a behavior regulator of the myzus persicae, so that green control of the myzus persicae is realized. In order to solve the technical problems, the invention adopts the following technical scheme: the invention provides an application of 2-acetyl furan in aphid prevention and control, in particular to an application of 2-acetyl furan in aphid behavior regulation and control. Further, the prevention and control is attraction or repellency. The invention further provides a control agent for aphids, and the effective component of the control agent contains 2-acetyl furan. Preferably, the concentration of 2-acetylfuran in the control agent is 0.001-10 μg/mL. Still further, the control agent showed an attracting effect against myzus persicae when the concentration of 2-acetylfuran was 0.1. Mu.g/mL. When the concentration of the 2-acetyl furan is 0.01 mug/mL, the control agent has a repellent effect on the myzus persicae. The solvent of the control agent can be n-hexane. The invention discovers the bidirectional behavior response of 2-acetyl furan to aphid with concentration dependency for the first time, and accordingly provides the new application of the 2-acetyl furan in aphid monitoring and green prevention and control. The novel control agent capable of green control of aphids is provided, 2-acetyl furan is used as an active ingredient, and the control agent can show different behavior control effects according to different concentrations, so that the control agent plays a role of an attractant or a repellent. In practical application, the control agent can be used for aphid control in tobacco seedling stage, field seedling stage and vigorous growth stage. According to different prevention and control purposes, the prevention and control agent can be applied to the surfaces of tobacco plants and around planting areas or arranged in trapping devices and slow-release carriers so as to realize the attraction or the repellent regulation and control of the tobacco aphids. The specific application amount of the control agent can be adjusted according to the aphid generation density, the control purpose and the application mode, so that the effective behavior control concentration is preferably achieved in a unit application area. Compared with the prior art, the invention has the following advantages: The 2-acetyl furan provided by the invention has obvious concentration-dependent behavior regulation effect on aphids, and can select different concentrations according to control requirements, so that double behavior regulation on myzus persicae is realized. Drawings FIG. 1 shows the selective behavioral response of Aphis tabacum to different host plants; FIG. 2 shows the selection behavior of myzus persicae for different concentrations of 2-acetyl furan; FIG. 3 shows the selective behavioural response of myzus persicae to different concentrations of phellandrene; FIG. 4 shows the selective behavioural response of myzus persicae to different concentrations of hexyl acetate; FIG. 5 shows the binding of the Aphis tabacum odour binding protein to a fluorescent probe and to 2-acetyl furan.
