Embodiment 1

[0021] Embodiment 1, East Asia migratory locust locust gnat attractant and its attracting effect to East Asia migratory locust fourth instar locust nymph

[0022] Mix 1ml of paraffin oil with 0.1 μL, 0.5 μL, 1.0 μL, 10 μL, 30 μL, 50 μL and 100 μL of 2,5 dimethylpyrazine at room temperature to obtain the nymph attractant of East Asian migratory locust.

[0023] The Y-type locust olfactory behavior instrument provided by the Chinese invention patent ZL200810056093.4 is used to measure the tendency response of the fourth instar locust gnat of the East Asian migratory locust to the attractant. The specific method is:

[0024] Place the test insects at the entrance of the above-mentioned Y-type locust olfactory behavior instrument, start timing, and each insect takes five minutes. When the test insects enter the A area or B area of ​​the olfactory instrument and are still, it is considered that the test insects have made If the test insect is still in the C area after five minutes,...

Embodiment 2

[0030] Embodiment 2, the attractant of migratory locust migratory locust and its lure to the gnat gnat of migratory locust east asia five instars

[0031] Mix 1ml of paraffin oil with 0.1 μL, 0.5 μL, 1.0 μL, 10 μL, 30 μL, 50 μL and 100 μL of 2,5 dimethylpyrazine at room temperature to obtain the nymph attractant of East Asian migratory locust.

[0032] According to the same method as in Example 1, the tendency response of the fifth-instar locust gnats to the attractant was determined.

[0033] The above-mentioned assay method is set to repeat three times, and the average value is taken for data analysis, and the obtained results are as follows: image 3 and Figure 4 As shown, the ck group in the figure is the control group. in, image 3Represent the lure effect of the migratory locust attractant on five instar migratory locust gnats, wherein the abscissa concentration is the volume ratio of 2,5-dimethylpyrazine and paraffin oil, wherein, 2,5-dimethylpyrazine The volume un...

Abstract

The invention discloses a Locusta migratoria manilensis locust nymph attractant and a preparation method thereof. The Locusta migratoria manilensis locust nymph attractant is composed of paraffin oil and 2,5-dimethyl pyrazine. In the attractant, the volume ratio of the paraffin oil to 2,5-dimethyl pyrazine is 1mL:(0.5-1.5mu L), preferably 1mL:0.5mu L. In the attractant and preparations of the attractant provided by the invention, 2,5-dimethyl pyrazine is the metabolic product of Locusta migratoria manilensis, is nonhazardous to the environment, human, livestocks and fowls, is safe to natural enemies and belongs to natural pesticide. The attractant and the relevant preparations of the attractant have obvious attracting action on the Locusta migratoria manilensis locust nymph, but do not have obvious attracting action on imagos; and the attractant and the relevant preparations of the attractant have the functions of regulating and controlling the behaviours of the Locusta migratoria manilensis and are favourable to the prevention and control of Locusta migratoria manilensis and the monitoring of the trends of the population quantity of Locusta migratoria manilensis.

Description

technical field [0001] The invention belongs to the field of pest control, in particular to an attractant for migratory locusts and a preparation method thereof. Background technique [0002] Locusts are major pests that seriously threaten my country's agricultural and animal husbandry production. The East Asian migratory locust is the most important species causing devastating agricultural disasters. At present, the method of controlling this pest is mainly chemical pesticide control. Although the large-scale use of chemical pesticides can effectively control locust infestation, it will also bring environmental pollution, excessive chemical pesticide residues in agricultural products, increased resistance of locusts, and increased control costs. Adverse consequences such as serious incidents of human and animal poisoning. Therefore, it is a very urgent task to adopt control methods that can replace chemical pesticides in order to achieve the goal of sustainable developmen...
