Problems solved by technology

Although sex pheromones have the advantages of strong selectivity, trace efficiency, and environmental friendliness, they can only trap and kill male individuals of the same species, and can only achieve better results for species with a single mating habit, and lose when the population density of wild female moths is high. effect

Embodiment 1

[0017] Preparation of Embodiment 1 Spodoptera lettuce luring composition

[0018] Add the n-hexane solution containing the synergist dropwise on the lure containing the sexual attractant of Spodoptera lettuce, after the n-hexane volatilizes, then add the n-hexane dropwise on the lure, and after the n-hexane volatilizes, the A lure core containing the trapping composition for Spodoptera lettuce is prepared, the lure core is placed in a barrel-shaped trap, and then the trap is placed in a field where lettuce winter night occurs more seriously. In order to ensure the release effect, 150-500 μg of the lure composition for Spodoptera lettuce is placed in each rubber lure core, and the average distance between the traps is 10m. In order to further illustrate the feasibility of the present embodiment, 18 specific formulas are provided in table 1:

[0019] Table 1

[0020]

Embodiment 2

[0021] The synergistic effect of embodiment 2 different formula synergists to sex attractant of lettuce spodoptera

[0022] Select the relatively serious plots where Spodoptera lettuce occurs, with an area of ​​more than 20 mu. Each formula sets the lure core at a height of about 150cm from the ground, and the distance between the traps is about 10m. Place the above-mentioned trapping combination containing Spodoptera lettuce at random. Barrel traps for animals were set up with 3 repetitions for each treatment. The number of trapping Spodoptera lettuce was investigated every two days after placement, and the trapping position was changed randomly, and the investigation continued for 30 days. The survey results are shown in Table 2:

[0023] Table 2

[0024]

[0025]

[0026] From the results in Table 2, it can be seen that adding a synergist to the sex attractant of Spodoptera lettuce can increase the number of trapping males of Spodoptera lettuce to a certain extent, ...

Abstract

The invention discloses a Cucullia fraterna Butler trapping composition and application thereof. The Cucullia fraterna Butler trapping composition comprises a Cucullia fraterna Butler sex attractant and a synergist, wherein the Cucullia fraterna Butler sex attractant comprises cis-9-tetradecene acetate, cis-11-hexadecenol and cis-9-hexadecenal; the synergist is selected from host plant volatile matter which comprises one or two of n-hexacosanol and hydroxymethylbenzoic acid; the mass ratio of the Cucullia fraterna Butler sex attractant to the synergist is 1:(0.2-1.2). The Cucullia fraterna Butler trapping composition can be accurately applied to Cucullia fraterna Butler Cucullia fraterna Butler condition prediction and large-scale trapping and is significant to comprehensive Cucullia fraterna Butler treatment.

Description

technical field [0001] The invention belongs to the technical field of insect sex pheromone preparation, and in particular relates to a composition for trapping Spodoptera lettuce and its application. Background technique [0002] Lettuce winter moth (Cucullia fraterna Butler) belongs to Lepidoptera, Noctuidae, and is one of the important agricultural pests. The larvae damage the tender leaves and flowers of Geba, and also harm vegetables such as lettuce, causing the plants to not grow normally, resulting in a serious loss of economic crop benefits. Adults are mainly distributed in Heilongjiang, Inner Mongolia, Xinjiang, Jiangxi, Liaoning, Jilin, Zhejiang and other provinces in China. Jilin and Liaoning have two generations a year, live through the winter as pupae, and larvae seriously damage lettuce from late June to early September. Adults are nocturnal, concealed and phototaxis, and have good taxis to sweet and sour liquid. It is difficult to control adults, and light t...
