Problems solved by technology

[0007] The method of the present invention is aimed at the problem that the peach small damage is rampant and the duration of the occurrence period is long, the generation overlaps, the key period of prevention and control cannot be effectively grasped, the control effect is not ideal enough, and the key period of prevention and control cannot be accurately determined. , the traditional method of preventing and controlling peach borer was changed from the control on the tree to the control under the tree. By using the peach lure to monitor the occurrence of the field, the inventor unexpectedly found that the combination of Hemibradine indica and hexaflumuron had a good effect on the peach borer. The control shows the advantage of obvious synergistic effect, which can not only effectively improve the control effect on mature larvae, but also prevent the offspring from forming effective oviposition, and inhibit the oviposition and hatching rate of offspring to the greatest extent, and the effect is obvious

Embodiment 1

[0060] A method for enhancing the control effect of small peach borer, comprising the following steps:

[0061] (1) Choose loose and aerated soil for site preparation, plant apples, the variety is Red Fuji, and the distance between plants and rows is 3m×4m.

[0062] (2) After mid-April, small peach lures were hung for monitoring, and when the first adult was caught, the nematode hexaflumuron suspension was applied in the apple orchard. Dilute hexaflumuron with water to prepare a hexaflumuron dilution, mix the hexaflumuron dilution with the entomopathogenic nematode Heterorhabditis indica LN2 that meets the detection conditions to prepare the nematode hexaflumuron suspension, and the nematode hexaflumuron suspension in the nematode Concentration is 800IJS / mL, and hexaflumuron concentration is 15mg / L; Carry out normal field management after application.

Embodiment 2

[0064] The same method as described in Example 1 for enhancing the control effect of the small peach borer worm, the difference is that the amount of the nematode hexaflumuron suspension meets 25 million nematodes per mu, and the concentration of the nematode hexaflumuron suspension in the nematode hexaflumuron suspension is 18mg / L.

Embodiment 3

[0066] The same method as described in Example 1 for enhancing the control effect of the small peach borer worm, except that the dosage of the nematode hexaflumuron suspension meets 30 million nematodes per mu, and the concentration of the nematode hexaflumuron suspension in the nematode hexaflumuron suspension is 18mg / L.

Abstract

The invention relates to a method for enhancing the control effect of peach fruit moths. The method includes the steps of before overwintering mature larvae of the peach fruit moths come out of the ground for eclosion each year, mixing hexaflumuron diluent with entomopathogenic nematodes in accordance with test conditions to prepare nematode hexaflumuron suspension liquid, wherein the concentration of the nematodes in the nematode hexaflumuron suspension liquid is 500-1000 IJS / mL, and the concentration of hexaflumuron is 15-20 mg / L; when a lure lures a first imago, applying the nematode hexaflumuron suspension liquid in an orchard to kill the mature larvae of the peach fruit moths. The method can effectively solve the key technical problems that the emergence period of the peach fruit moths is long in duration, generations overlap, a key control period cannot be effectively grasped, and the control effect is unsatisfactory; therefore, descendants of the peach fruit moth do not form effective egg laying to inhibit the egg laying amount and egg hatchability of the descendants to the maximum extent, in addition, the usage amount of the entomopathogenic nematodes and the hexaflumuron can be decreased, so that the environment-friendly control purpose of the peach fruit moths can be achieved.

Description

technical field [0001] The invention relates to a method for enhancing the control effect of peach borer, and belongs to the technical field of biological control. Background technique [0002] Peach fruit borer (Carposina sasakii Matsmura), also known as peach fruit moth, is referred to as peach small, belongs to the family Lepidoptera Carposina sasakii, mainly occurs in the eastern and northern regions of my country, and is harmful to apples, hawthorns, jujubes, apricots and peach trees. It is the most serious damage, and it is a very serious fruit-boring pest in the production of fruit trees in northern my country. Peach borer worms produce 1-2 generations a year in northern my country. They use mature larvae as winter cocoons to overwinter in the soil under the tree. The next year the overwintering adults climb out of the soil and climb the tree to lay eggs. The larvae eat directly after hatching. The pulp will make the affected fruit full of insect feces and unfit for co...
