Description
Technical Field
A composition for preventing and controlling mulberry borer and application thereof, belonging to the technical field of pollution-free biological prevention and control of pests.
Background
The mulberry stem borer (Diaphania pylalis (Walker)) belongs to the family of Lepidoptera borer, also called as oil worm, budworm, leaf roller and the like, and occurs in other provincial silkworm areas in China except Xinjiang. The host plant of the mulberry borer is mainly mulberry and is one of the important pests of the mulberry. In recent years, the occurrence of the Jiangxi mulberry borer is generally serious and gradually becomes a superior pest in mulberry field. The mulberry borer is harmed by larvae, the larvae which are hatched at first age eat young tips and buds of the mulberry, the larvae of 3 th age begin to spit and sew into curled leaves or overlap two or more leaves, the mesophyll is eaten inside, the upper epidermis is left, and the harmed leaves often form transparent gray films. The excrement of the mulberry borer pollutes the mulberry leaves, influences the leaf quality and silkworm feeding, and is easy to cause silkworm diseases. The mulberry borer in Jiangxi area can grow for 5-6 generations in 1 year, mature larvae grow thin cocoons at cracks, wormholes and other places of trunks to live through the winter, the larvae start to move in the first ten days of 4 months every year and stop moving in the last 10 months, obvious generation overlapping phenomenon is achieved, the optimal prevention and control period of the mulberry borer larvae is 1-2 years, the prevention and control difficulty is high after the mulberry borers miss the proper prevention and control period and roll leaves, outbreak and disaster are easy to happen, the production safety of silkworm eggs is seriously influenced, the quality safety of silkworm cocoons is threatened, and even the silkworm farmers do not accept grains. According to survey statistics, the damage rate of the mulberry borers to the mulberry trees can reach 67 percent, even 100 percent; in addition, the silkworm diseases caused by the damage of the mulberry borer can be pandemic, so that the elimination rate of silkworm seeds reaches more than 12.4 percent, and the disease rate of the silkworm seeds exceeds 80 percent. Therefore, great attention must be paid to the effective prevention and control of mulberry stem borer.
At present, the prevention and treatment of mulberry stem borers mainly depend on traditional chemical pesticides, and the prevention and treatment technology is single. On one hand, chemical pesticides are excessively depended on to control the mulberry borers, so that the drug resistance of the mulberry borers is continuously improved, the control effect is gradually reduced, the control difficulty is gradually increased, meanwhile, silkworms are sensitive to chemical agents, and the mulberry leaf pesticide residue seriously influences the safe production of the mulberry silkworms; on the other hand, if chemical pesticides are used for a long time, the mulberry field has serious environmental pollution, which not only harms the health of people and livestock, but also threatens the living environment of the natural enemy organisms of the pests in the mulberry field, so that the quantity of the natural enemies of the pests is reduced rapidly, and the ecological natural regulation and control of the mulberry field are damaged.
Most of the researches on the tropism and disorientation of insect olfactory organ to favorite odorant are insect food attractant and sex attractant. The food attractant and the sex attractant are important technical measures for developing green prevention and control of crop pests and promoting reduction and pest control of pesticides. In recent years, the research and application of pest control technology for controlling pests by using food or sex attractant are widely carried out, compared with the traditional chemical pesticide, the food or sex attractant depends on the omnibearing three-dimensional coverage of special odor substances in the air, has strong specificity for trapping and killing pests, high efficiency and no pollution, and solves the defect of untimely chemical control. However, no report is found in the technical research of utilizing the tropism substance and the disorientation substance to cooperatively control the mulberry borer imagoes.

From the data of FIG. 1, it can be seen that: treating CQ2 trap to trap 234.1 head of mulberry borer; by treating the ZH2 trap to trap 573.6 heads of the mulberry borer imagoes, the trapping amount of the combined formula 2 is improved by 13.49 percent compared with the sum of the traps alone.
Example 5
Formula 3 of the composition for preventing and treating mulberry borers: the pure tropism decoy substance and the pure tropism decoy substance are composed according to a mass ratio of 4:5, and comprise 28mg of trans-3-hexene-1-ol (E3-Hexen-1-ol), 20mg of n-butyl acrylate (2-Propenoic acid, butyl ester) and 12mg of n-Hexacosane (Hexacosane); (cis 3, trans 16) -5-methyloctadecadienol (E2, Z15, Me 14-octadienen-1-ol) 37.5mg and 11Z-Hexadecenal (Z11-Hexadecenal)37.5mg, and the components are uniformly mixed to obtain the composition formula 1 (represented by ZH 3) for preventing and treating the mulberry borer.
Respectively placing the slow-release carrier dropwise added with the pure CQ1, CM and ZH1 to-be-tested agents in a trap, and taking the same amount of redistilled n hexane as a control to test the luring effect of the paradise mulberry borer. The traps containing 4 treatments of the test agents were arranged symmetrically in a square with equal spacing, with consistent suspension height and suspension time, and 3 replicates were set. According to the prediction and forecast of the mulberry borers, the eclosion period of the mulberry borers in the 9-month period of the large outbreak of the mulberry borers is selected for the test, the continuous investigation is carried out for 10d, the treatment in the investigation period is carried out at 16:00 in the afternoon at the same time or the test agent is added, and the number of the mulberry borers trapped is recorded in the 9:00 in the morning. From the data of FIG. 1, it can be seen that: treating CQ3 trap to trap 236.5 head of mulberry borer imagoes; when the ZH3 trap is treated to trap 517.4 heads of the mulberry borer imagoes, the trapping amount of the combined formula 2 is increased by 1.89% compared with the sum of the traps alone.
The trapping effect of the compositions with different formulas on the mulberry borers is shown as follows: the trapping effect of the composition of the tropism trapping substance and the disorientation trapping substance is better than the sum of the effects of single use, wherein the composition for preventing and treating the mulberry borers, which is composed of the pure tropism trapping substance and the pure disorientation trapping substance according to the mass ratio of 3:5, has the best formula effect, the efficiency is improved by 13.49%, and the prevention effect is remarkably different from the prevention effect of the composition for preventing and treating the mulberry borers according to the mass ratios of 2:5 and 4: 5. Therefore, the formula provided by the invention has an obvious trapping effect on the mulberry borers, and can be applied to mulberry gardens for carrying out pollution-free control on the mulberry borers.
