Abstract

The invention relates to a composition of an insect pheromone attractant for Spodoptera frugiperda, which belongs to the field of plant protection, and is characterized in that the composition comprises the following components: 0.5-5% of Spodoptera frugiperda pheromone, 85-98% of a slow-release solvent, 0.1-0.5% of a synergist and 0.5-10% of a protective agent, wherein the components of the Spodoptera frugiperda pheromone comprise: (Z)-11-hexadecene acetate, (Z)-7-dodecene acetate, (E)-7-dodecene acetate, (Z)-9-tetradecene acetate, (Z)-9-dodecene acetate, (Z)-11-tetradecene acetate, (E)-7-dodecene acetate, (Z)-9-tetradecene acetate, (Z)-9-dodecene acetate and (Z)-11-tetradecene acetate. The attractant composition disclosed by the invention has the characteristics of strong specificity totarget pests, namely the Spodoptera frugiperda, good trapping effect, stable attractant and long lasting period, the lasting period can reach 90 days or more, the miscellaneous insect rate is less than 1%, and the requirements of accurate and stable monitoring of the target pests in the field can be met.

Description

technical field [0001] The invention belongs to the field of plant protection, in particular to a composition of an insect pheromone attractant for Spodoptera frugiperda. Background technique [0002] Spodoptera frugiperda ( Spodoptera frugiperda ), Lepidoptera Spodoptera genus, divided into two haplotypes, maize strains and rice strains, originally occurred in subtropical and tropical America, and occurred in Nigeria, Africa in 2016. In two years, it swept across 44 African countries and regions entered from Yunnan, China in January 2019. In September of the same year, 25 provinces across the country discovered its damage. The actual damage area was 164,000 hectares, but the insect area was more than 1 million hectares, which is a serious threat to agricultural production. The migratory pests have the characteristics of strong adaptability, wide host, wide distribution, rapid migration, serious damage, and strong reproductive ability. At this stage, it is necessary to accu...
