Abstract

The invention provides a fan-type insecticidal incense, which comprises a drug impregnated body and a fan device accommodating the drug impregnated body, wherein the drug impregnated body comprises the following components in percentage by weight: 0.5 to 15 percent of pyrethroid compound serving as an insecticidal active component and shown by a formula (1), 0 to 50 percent of solvent, 30 to 99.9percent of impregnated carrier and 0 to 5 percent of auxiliary agent; in the formula (1), R is a hydrogen atom, methyl, methoxyl or methoxymethyl; and the fan device comprises the parts of a normal fan: a power supply, a motor, fan blades and a fixing device for fixing the parts and the drug impregnated body, wherein the drug impregnated body is replaceable. The fan-type insecticidal incense can be used for controlling sanitary insect pests.

Description

technical field [0001] The invention relates to a hygienic insecticide, in particular to a fan-type insecticidal incense and its application in the prevention and control of hygienic pests. Background technique [0002] The pyrethroid compound represented by formula (1), wherein R is a hydrogen atom, methyl, methoxy or methoxymethyl, has insecticidal activity and has been disclosed in documents such as JP2002-249464A, CN101381306A; on the other hand, JP2004 -222725A proposes a convenient fan-type mosquito repellent, in which Dimefluthrin and Metofluthrin are used as effective ingredients, but in actual use we still feel that Its efficacy is not ideal enough. [0003] [0004] We have found through research that the pyrethroid compounds represented by formula (1) have very high vapor pressures, and are arranged in descending order of vapor pressure, 2,3,5,6-tetrafluoro-4-methoxybenzyl- 3-(3,3,3-Trifluoro-1-propenyl)-2,2-dimethylcyclopropanecarboxylate (2176.6Pa)>2,3,5...
