CN102308786A - Prevention and control method for destructive soil insects of farm crop - Google Patents

Abstract

The invention discloses a prevention and control method for destructive soil insects of a farm crop, relating to methods for preventing and controlling destructive insects. The prevention and control method is characterized by comprising the following steps: light trapping and killing: mole crickets and a plurality of scarab male worms have stronger phototaxis, and the mole crickets and the scarab male worms can be trapped and killed by utilizing black light lamps at the beginning of a development period and during the development period; manual catching: (1) scarabs have a feign death property, a trunk is shaken when the scarabs eat leaves at night, and then adult scarabs feigning to be dead and falling onto the ground are picked up and killed; (2) when the spot films of cutworms appear, a way of scarifying soil to catch the cutworms is adopted; and (3) a method for plowing the soil to pick up white grubs can be adopted to kill the white grubs; and manual digging and killing: (1) nests are dug to kill the destructive insects in spring, at the end of March and at the beginning of April, the destructive insects begin raising to the shallow soil but do not migrate outwards yet, the nests are dug to kill the destructive insects by combining the soil leveling, and the destructive insects can be controlled by digging the nests generally for about 15 centimeters; and (2) the nests are dug to destroy eggs in summer, the digging of the nests is carried out by combining with weeding from the last ten days of May to the middle ten days of July, weeds are firstly weeded shallowly for about 3.3 centimeters, observation is carried out while the weeding is carried out, and the nests are deeply dug to destroy egg nests if the egg nests are discovered.

Description

The method of preventing and treating of crops soil insect

Technical field

The present invention relates to the method for pest control, be specifically related to the method for preventing and treating of a kind of crops soil insect.

Background technology

In recent years, pest damage is on the rise under the vegetable field, is difficult to control, brings bigger economic loss to the vegetable grower.The soil insect kind is a lot, comprises mainly that cutworm, grub, mole cricket, wireworm, root maggot, root aphid, root weevil, root are chrysomelid, root longicorn, cricket, mole cricket etc.Its host types is complicated, how to cause harm the seed of the crop of mainly causing harm, underground part and subaerial rhizome portion at spring and autumn.Often cause and hinder root, dead seedling, so that the disconnected ridge that is short of seedling.Most soil insects have more stable ecotope, a little less than life cycle long, the animal migration, also have with ground temperature and change vertical movable characteristics, form hazard boom in spring, two seasons of autumn.If environmental factor changes or artificial disturbance, then population density can descend by nature.It is main that present controlling underground pest method mainly adopts chemical pesticide soil such as chemical pesticide phoxim, chlopyrifos to execute, because long-term single administration causes the soil insect pesticide resistance to strengthen, the insect protected seedling protecting effect is undesirable.

Summary of the invention

It is a kind of simple and practical that technical problem to be solved by this invention is to provide, and crops do not had the method for preventing and treating of the crops soil insect of injury.

Technical problem to be solved by this invention adopts following technical scheme to realize,

The method of preventing and treating of crops soil insect is characterized in that: it is following that it prevents and treats method,

A, light trap: the expensive first male worm of mole cricket and multiple gold has stronger phototaxis, can begin contain to send out and contain send out during, utilize the black light lamp trapping;

B, the artificial seizure: (1) Jin Guijia has seemingly-dead property, and the vibrations trunk is picked up seemingly-dead born adult then and killed when getting the food leaf its evening; (2) when the cutworm spot film takes place, adopt and dial native catching mode; The method of (3) picking up worm after can taking to plough to grub is eliminated;

C, manual work are dug and killed: dig the nest deinsectization (1) spring, and at the beginning of 4 months by the end of March, insect begins to rise to shallow soil but when not going out to move as yet, digs the nest deinsectization in conjunction with leveling land, and generally digging about 15 centimetres is controlled; (2) dig nest summer and ruin ovum, combine to hoe up weeds late May to mid-July to carry out, shallow hoe is about 3.3 centimetres earlier, sees while uprooting, and discovery ovum nest will deep-cut to destroy and get final product.

The invention has the beneficial effects as follows: the inventive method is simple and practical, can kill various soil insects, does not need use of insecticide, and crops are had no injury and side effect.

Embodiment

For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with specific embodiment, further set forth the present invention.

The method of preventing and treating of crops soil insect, it is following that it prevents and treats method,

A, light trap: the expensive first male worm of mole cricket and multiple gold has stronger phototaxis, can begin contain to send out and contain send out during, utilize the black light lamp trapping;

B, the artificial seizure: (1) Jin Guijia has seemingly-dead property, and the vibrations trunk is picked up seemingly-dead born adult then and killed when getting the food leaf its evening; (2) when the cutworm spot film takes place, adopt and dial native catching mode; The method of (3) picking up worm after can taking to plough to grub is eliminated;

C, manual work are dug and killed: dig the nest deinsectization (1) spring, and at the beginning of 4 months by the end of March, insect begins to rise to shallow soil but when not going out to move as yet, digs the nest deinsectization in conjunction with leveling land, and generally digging about 15 centimetres is controlled; (2) dig nest summer and ruin ovum, combine to hoe up weeds late May to mid-July to carry out, shallow hoe is about 3.3 centimetres earlier, sees while uprooting, and discovery ovum nest will deep-cut to destroy and get final product.

More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
