However, the process of identifying the odor by the insects is very complicated, and the control effect of the attractant is easily influenced by factors such as field background odor and the like. Therefore, how to improve the attraction effect of various attractants becomes a problem to be solved urgently.
In nature, plants produce many small-molecule volatile secondary metabolites, such as terpenes, alkaloids, flavones, steroids, and phenolic acids, in order to resist harmful organisms, and these substances can produce a repellent effect on pests, and are an important way for plants to defend insects. China has recorded that hemp leaves, folium artemisiae argyi and the like are used for repelling mosquitoes in the 11 th century, and at present, the substances play an important role in the prevention and control of pests.
Research shows that the compounds with repelling and attracting functions are combined to form a push-pull strategy, so that the synergistic effect can be achieved. The strategy is applied in actual production at present, and can play a good role in controlling pests such as cotton bollworm Helicoverpa armigera, Sogatella furcifera, Nilaparvata lugens and the like.

The repelling and attracting effects of the green plant bug, the bemisia tabaci and the triboliurus castaneus adults are analyzed by adopting chi-square test. All data processing was done using the SPSS Statistics 17.0 software.
10. Results of the experiment
As can be seen from fig. 3, for the female green plant bug, the linalool and 5-hydroxymethylfurfural have the highest relative EAG values, which can reach 1.4901 ± 0.1367(P ═ 0.0290, F ═ 7.5320) and 1.3446 ± 0.1422(P ═ 0.0404, F ═ 4.6260) which are respectively significantly higher than the syringin potential reaction, 0.7800 ± 0.2197. The potential response of the male green plant bug is similar to that of the female green plant bug, the relative EAG values of linalool and 5-hydroxymethylfurfural are 1.5628 +/-0.1422 (P is 0.0103, and F is 8.6320), 1.4093 +/-0.1620 (P is 0.0303, and F is 5.0770), and the potential response is also obviously higher than that of syringin 0.7955 +/-0.2191.
According to electrophysiological reaction, two compounds of linalool and 5-hydroxymethyl furfural are selected to measure the olfactory reaction of lygus lucorum, and the result shows that linalool can treat the female lygus lucorum (P ═ 0.0068, chi)27.3143) and males (P0.0038, χ28.3768), the ratio of the kidney beans after linalool treatment is 33.75 percent, the ratio of the male worms is 32.5 percent, and the 5-hydroxymethylfurfural is used for the female worms (P)<0.001，χ245.2308) and males (P)<0.001，χ231.2432) showed very significant attracting effect, 75% of the tested adults had female insects and 67.5% of the male insects selected for 5-hydroxymethylfurfural-treated kidney beans.

Figure BDA0003334114240000071
Bars indicate that the olfactory response of adults of a sex to a volatile was very different from the control group (P < 0.01).
Because the electrophysiological and behavioral responses to volatile matters between the male and female lygus lucorum are similar, the sex of the adult cannot be distinguished in subsequent experiments. According to the experimental results, the attracting activity of the 5-hydroxymethylfurfural on the lygus lucorum with different dilution times is determined. As can be seen from fig. 5, the attraction effect of 5-hydroxymethylfurfural on apolygus lucorum is not linear with the concentration, and the stock solution (P ═ 0.0285, χ) is higher than that of the control group24.8000) with 100-fold dilution (P)<0.001，χ216.0000) showed significant or very significant attraction, with selectivity response rates of 51.43% and 70.59%, respectively.
According to the experimental results, linalool with the repelling effect on the lygus lucorum is selected, and the repelling effect on two common pests is determined. As shown in table 2, linalool showed very significant repellent effects on both Q-type bemisia tabaci and tribolium castaneum, and the selective reaction rates of the treatment groups were 32.31% and 25.00%, respectively.

Figure BDA0003334114240000081
According to the experimental results, 5-hydroxymethylfurfural with attraction effect on lygus lucorum is selected, and the attraction effect on two common pests is determined. As shown in FIGS. 6 and 7, a 5-hydroxymethylfurfural stock solution (P)<0.001，χ284.5000), 10-fold dilution (P)<0.001，χ230.1538), 100 times diluted solution (P)<0.001，χ274.3226) the number of traps was significantly higher than the control group. The trapping amount of 1000 times of dilution was not significantly different from the control (P0.5449, χ)20.3665). However, the compound does not generate obvious attraction effect (P) on the tribolium castrate>0.05)。
According to the experimental result, the linalool stock solution and the 5-hydroxymethylfurfural 100-fold diluent are selected to combine a 'push-pull' strategy, and the influence of the strategy on the olfactory selection of lygus lucorum is measured. As can be seen from table 3, the amount of insects fed on kidney beans treated by the "push-pull" strategy was significantly lower than that of the blank control (P <0.001, F value 52.9410) and the linalool control (P value 0.0013, F value 18.2860), but was not significantly different from that of the 5-hydroxymethylfurfural control (P value 0.0678, F value 2.8820). The insect quantity on the treated armyworm plate is significantly higher than that of the linalool control (P & ltSUB & gt 0.0111 & lt/SUB & gt, F & ltSUB & gt 20.00 & lt/SUB & gt), and is very significantly higher than that of the blank control (P & ltSUB & gt 0.0026 & lt/SUB & gt, F & ltSUB & gt 45.00 & lt/SUB & gt), but has no significant difference with the 5-hydroxymethylfurfural control (P & ltSUB & gt 0.2477 & lt/SUB & gt, F & ltSUB & gt 1.8290 & lt/SUB & gt).

Data in table are mean ± sem; the different upper and lower case letters represent the very significant (P <0.01) and significant (P <0.05) differences in the numbers of adults on kidney beans or myxoid plates between treatment and control, respectively.
According to the experimental result, the combination of the push-pull strategy for preventing and controlling the Q-type bemisia tabaci is linalool and 5-hydroxymethylfurfural stock solution. As can be seen from table 4, the number of bemisia tabaci on cotton leaves of the treated group was significantly lower than that of the blank control group (P ═ 0.0304, F ═ 5.061), and there was no significant difference between the linalool-only and the 5-hydroxymethylfurfural-only control group (P ═ 0.6490, F ═ 0.351). The white board traps of the treatment group (P0.0111, F47.035) and the control group with only 5-hydroxymethylfurfural (P0.0038, F10.443) were significantly higher than the blank control.
