Embodiment 1

[0019] Field trapping test of embodiment 1 Spodoptera frugiperda

[0020] The lure core of the prepared fall armyworm attractant composition is placed in a barrel trap and placed in the area where fall armyworm occurs. 23 specific formulas are given in Table 1, wherein the formula with sex pheromone quality 1000 μg contains cis-9-tetradecen-1-ol acetate 840 μg, cis-11-hexadecen-1-ol acetate 130 μg of ester, 30 μg of cis-7-dodecen-1-ol acetate.

[0023]

[0024] In order to ensure the release effect, the average spacing between the traps is 20-30m, the height of the lure core is set at 1.5-2m, and the traps are arranged in random blocks. After the setting, the number of fall armyworms trapped was investigated every 3 days, and the investigation continued for 30 days. The survey results are shown in Table 2.

Abstract

The invention discloses an attractant composition for spodoptera frugiperda and application of the attractant composition. The spodoptera frugiperda sex pheromone composition comprises a spodoptera frugiperda sex pheromone component and a synergist in a mass ratio of 5: 2. Wherein the sex pheromone is prepared from the following components: cis-9-tetradecene-1-alcohol acetate, cis-7-dodecene-1-alcohol acetate and cis-11-hexadecene-1-alcohol acetate, and the synergist is one or more of nonanal, 2-heptanone and cis-9-tetradecene-1-alcohol. The attractant composition can attract female and male spodoptera exigua at the same time, effectively reduce the cardinal number of spodoptera exigua, and rapidly reduce the propagation rate, thereby achieving the purpose of efficiently preventing and treating spodoptera exigua. The attractant composition is high in specificity, the mixed insect rate is lower than 5%, meanwhile, the attractant composition can be applied to insect situation forecasting and mass trapping and killing, and the attractant composition has important significance on comprehensive prevention and control of the grassland spodoptera exigua.

Description

technical field [0001] The invention belongs to the technical field of biological control, and in particular relates to an attractant composition for controlling Spodoptera frugiperda and its application. Background technique [0002] Spodoptera frugiperda (J.E.Smith) belongs to Lepidoptera Noctuidae, also known as fall armyworm, and is a unique pest in the Americas. Fall armyworm can feed on 353 plant species, including crops such as corn, rice, sorghum, millet, sugar cane, vegetables and cotton. Fall armyworm is one of the most destructive corn pests in the Americas and can have major impacts on yield and quality if not adequately controlled. Since the fall armyworm broke out in Africa in 2016, it has become the main corn pest in central and western Africa. The insect invaded my country's Yunnan and Guangxi from Southeast Asia in 2019, and has now caused damage in 18 provinces (cities, districts), seriously threatening my country's corn and other food production. At pre...
