Problems solved by technology

[0003] At present, the control methods for the stinkbug are mainly chemical control, but due to the long-term and large-scale use of chemical pesticides, the stinkbug has developed resistance to many types of pesticides, and the effect of chemical control has declined significantly. Therefore, the use of biological control method is imminent

Embodiment 1

[0021] Example 1: Y-Tube Behavioral Response

[0022] Experiments were carried out under natural light conditions with room temperature of 24±1°C and relative air humidity of 40±5%. Before the experiment, the Y-type olfactometer (Y-type tube) was washed with acetone and n-hexane successively. Decanal, heptanal, nonanal and linalool were prepared with n-hexane into three concentration gradients of 0.1 μg / μL, 1 μg / μL and 10 μg / μL to be tested. Using n-hexane as the control, take 10 μL of the test sample. Drop the sample and n-hexane on two different filter papers respectively, put the two filter paper strips into the odor source device bottles on both sides of the Y-shaped tube, turn on the air sampler and make the airflow in the Y-shaped tube 100mL. / min, and then put the male and female adult worms into the release tube and observe for 5 min. For the first time, the odorant was considered to have selected the odor source when its arm was more than 5cm and the duration was mor...

Embodiment 2

[0024] Example 2: EAG Relative Response Values

[0025] EAG (Syntech, Germany) was used to measure the electrophysiological responses of male and female adult worms to different concentrations of decanal, heptanal, nonanal and linalool. The specific operation steps are as follows: decanal, heptanal, nonanal and linalool are prepared with n-hexane into three concentration gradients of 1 μg / μL, 10 μg / μL and 100 μg / μL. Drop 10 μL of the sample to be tested or n-hexane on the filter paper, and then put the filter paper into the sample tube. Cut off the antennae of the adult Pseudomonas spp. from the base, cut off a small part (about 1 mm) from the end of the antennae, and glue the two ends of the antennae to the fork electrodes using conductive glue. Adjust the continuous air flow at the antennae to 5mL / s. When testing, switch the continuous air flow to the stimulating airflow of the sample to be tested, that is, the continuous air flow is suspended, the stimulated airflow of th...

Embodiment 3

[0027] Example 3: Field experiment

[0028] Test site: Soybean field in the experimental field of Fuyang Academy of Agricultural Sciences, Fuyang City, Anhui Province. The planting area in this area is 40 mu.

Abstract

The invention discloses a bee bug repellent and application thereof. The apis cerana repellent is prepared from the following components in percentage by volume: 0.01 percent to 0.1 percent of capraldehyde, 0.01 percent to 0.1 percent of heptanal, 0.1 percent to 1 percent of nonanal, 0.1 percent to 1 percent of linalool and 97.8 percent to 99.78 percent of a solvent. Compared with the prior art, the decorus lividus repellent provided by the invention takes capraldehyde, heptanal, nonanal and linalool as repellent active ingredients, the active ingredients supplement each other, have a synergistic effect and have good oviposition and antifeedant repellent effects on decorus lividus, and the repellent rate of the decorus lividus reaches up to 95.43% + / -0.48% and is obviously higher than that of a single active ingredient. And the active components are all common natural plant components, are harmless to human bodies, are biodegradable, are environment-friendly, and are convenient and safe to use.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a repellent for S. Background technique [0002] Riptortus pedestris is an economic pest distributed on soybeans in Japan, Korea and China. Also known as the white-striped beetle stink bug and the bean edge stink bug, it belongs to Hemiptera, Arachnididae, and its piercing and sucking harms more than 30 crops such as soybeans, kidney beans, sesame, rice, apples, and sweet persimmons. Its adults and nymphs thrive in clusters, causing flower pods to fall off, pods not solid, and grain deformities, which in turn lead to damage to crop yield and quality. [0003] At present, the main control methods for P. spp A method is imminent. There are few research reports on the repellent effect of A. pipiens. Therefore, the present invention proposes a new type of repellent for A. pipiens. SUMMARY OF THE INVENTION [0004] The first object of the present invention is to provide a p...
