Grapholitha molesta Busck (Grapholitha molesta Busck) belongs to Lepidoptera (Lepidotera) and small leaf roller moth (Tortricidae), and the mature fruits such as stony peach, cherry, apricot spring young sprout and harm pome apple and pear are mainly used throughout the year. Because the larvae are damaged by boring and eating, the overwintering place is hidden, the insect state time of other insect states exposed outside is short, great difficulty is brought to fruit growers in prevention and control, and the quality of fruits is seriously reduced. At present, the prevention and control means of the oriental fruit moth is mainly chemical pesticide control, which causes a series of defects of over-standard fruit pesticide residue, lower fruit quality, increment and decrement of orchard pests, enhancement of pest drug resistance, accumulation of natural enemy quantity, serious damage to orchard ecosystem balance and the like. The sugar-vinegar liquid is used as a broad-spectrum attractant, is a non-toxic and pollution-free effective control means for orchards, can attract both male and female adults, and has wide application prospect. However, the sugar-vinegar attractant is easy to evaporate in the field, the concentration is easy to change, and the control effect is seriously influenced.

Examples of the experiments

1. General description of the test site

The test area is located in a plant protection room base applied to Changli fruit tree research institute of agriculture and forestry academy of sciences in Hebei province, and the soil is loam. The natural conditions of the test area, such as terrain, landform, soil texture and the like, are basically consistent, the tested pear variety is 'yellow crown', the full bearing period is, and the plant spacing is 2m multiplied by 4 m.

2. Test materials

The trapper is a Beijing Zhongjie square triangle trapper.

3. Test method

The example and comparative example vinegared pastes were placed in the middle of an adhesive plate on traps, the traps were hung in a pear orchard endangered by Grapholitha molesta, the traps were hung 1.6m from the ground, each trap was spaced about 50m apart, statistics were performed every 7 days, the traps were nipped out with tweezers for each survey, the survey was performed for 60 days, statistics were performed again on day 60, and the results on day 60 are shown in Table 1.

4. Results and analysis

TABLE 1 Effect of trapping and killing Grapholitha molesta Busck by different substrate formulas

As can be seen from the table, examples 1 and 2 have better moisturizing effect in the field, still show a wet paste after 60 days of use, examples 3 and 4 have dry and hard paste and dry cracks in the field, and CK (sugar vinegar) evaporates faster in the field. The quantity analysis of the adult oriental fruit moth trapping formulas of different formulas shows that different formulas of the sugar, wine and vinegar paste have an attraction effect on oriental fruit moths, the average quantity of moth trapping of the formula (1) is obviously higher than that of other formulas, and the average amounts of oriental fruit moth trapping (head) of different formulas are respectively as follows: 117. 78.33, 71.67, 69.67, 22.67. The differences among example 1, example 2, example 3 and example 4 were not significant, the differences between example 1 and ck were significant, and the moisturizing effect and the insect-catching effect of comparative example 1, in which no glycerin paste was added, were also significantly deteriorated. The fruit decay rate of different formulas on orchards in a treatment area is analyzed, the fruit decay rate of the oriental fruit moth on fruits is reduced by the different formulas, and the effect of example 1 is superior to that of examples 2-4 and a blank control formula only using sugar wine. By combining the analysis, the ointment of the embodiment 1 has the optimal effect, and the embodiment 2 has the advantages of prolonged attraction time, obviously enhanced and stable attraction effect, environmental protection, high attraction and killing rate, strong specificity, low cost and easy popularization and application.
