Abstract

The invention provides a method for controlling aphides by using an aphid parasite mobile net cage and belongs to the biological control technology. The method comprises the following steps that: the bred stiff aphids are transferred in a mobile net cage which is formed by a net frame, a net drum, a net cover, a capping cover, a nutritional bowl, a floating disk and the like and placed in a big field; the hatched aphid parasites are bred and proliferated and fly out through meshes to infest the aphids in the big field; and thus, the effect of killing the aphids by the aphid parasites is achieved. The method has the advantages of avoiding anthropochory of epidemic diseases such as powdery mildew and tobacco viruses, achieving a quite good biological control effect on the aphids of tobacco and various crop, along with huge aphid cocoon breeding quantity, good aphid killing effect, easy operation and easy implementation.

Description

Move the method for net cage control aphid with aphid cocoon honeybee

Technical field

The invention belongs to the biological control technology, especially a kind of method that moves net cage control aphid with aphid cocoon honeybee.

Background technology

Aphid is a kind of insect, and it is made a living to suck the plant sap nutriment, and fertility is extremely strong, to agricultural, production of forestry is very harmful, people take the applying pesticides desinsection to prevent and treat mostly, and certain effect is arranged, but first if the improper easy contaminated environment of dispenser is destroyed the ecological balance; Second the pesticide residue in the agriculture and forestry product can bring injury to people, animal.By long-term observation, research, it is found that also there is the natural enemy of some aphids in occurring in nature, as coccinella septempunctata, aphid cocoon honeybee etc., wherein aphid cocoon honeybee belongs to a kind of insect in Hymenoptera, the aphidius gifuensis section, be easy to artificial propagation, input, big Tanaka's aphid is had the better prevention effect.Normally adopt two kinds of methods: the one, throw in stiff aphid sheet and become honeybee: 3 * 6 meters net cage is set in green house, cultivate the cigarette seedling inside, inoculation detoxification aphid when treating cigarette strain length to 12 slice leaf, allow it breed and inoculate aphid cocoon honeybee parasitism when a certain amount of again, when it is sprouted wings as yet, the tobacco leaf sheet of band aphid cocoon honeybee is not put in the vega, the aphid in parasitic big field after allowing it sprout wings, also available suction buzzer is collected the aphid cocoon honeybee that has sprouted wings in the net cage and is thrown in the land for growing field crops; Second method is to throw in stiff aphid seedling promptly: educate in booth earlier and plant the cigarette seedling, 4 leaves time inoculation aphid wholeheartedly, inoculate aphid cocoon honeybee parasitism when breeding some again, the preceding cigarette seedling is moved of sprouting wings amplified the field, the parasitic land for growing field crops of aphid cocoon honeybee aphid, above-mentioned two kinds of ways all can be played preferably throw the go out biological control effect of aphid of honeybee.But also find in practice, said method still comes with some shortcomings: at first be that environment such as temperature, humidity, illumination and land for growing field crops natural environment in the warm canopy net cage has big gap, the aphid cocoon honeybee survival rate of throwing in is not high, meets burning sun especially, heavy rain weather survival rate is just lower; Next is when throwing in stiff aphid sheet, stiff aphid seedling, if incomplete by parasitic aphid detoxification, tobacco leaf sheet or cigarette seedling have the white powder cause of disease, all cause anthropochory's eqpidemic disease easily; Moreover throw in during restricted 9-10 in the morning of release time, impressions must more than 2 batches, seeming wastes time and energy.

Summary of the invention

For remedying the deficiency of said method, the object of the present invention is to provide a kind of aphid cocoon honeybee breeding amount big, throw in land for growing field crops survival rate, spawning rate height, control efficiency is good, can avoid cause of diseases such as anthropochory's powdery mildew, tobacco virus, safety and reliability, time saving and energy saving a kind of aphid biological control method.

Specifically finish like this: in green house or net cage, bring out earlier the cigarette seedling, the wholeheartedly time inoculation aphid breeding of four leaves, when having 20 aphids, every strain cigarette seedling inoculates aphid cocoon honeybee parasitism again, form stiff aphid seedling about 15 days and throw in the land for growing field crops aphid of going out, stiff aphid seedling must be transplanted to earlier big Tanaka and be provided with in the mobile net cage that is assembled into by rack, net tube, guard, cap, nutrition basin, floating dish, allows behind the aphid cocoon bee eclosion mesh by net tube, guard fly to land for growing field crops parasitism aphid and reaches and prevent and treat purpose.

Described mobile net cage is by the affixed one-tenth rack of circular circle suitable for reading, end opening circle and 3-4 root post, be that the end opening of the hat guard suitable for reading and round of the cylindrical net tube of 40-60 order twines respectively and is placed in rack circle suitable for reading with reticular density again, a net tube end opening twines and is placed in nutrition basin waist and assembles, be covered with movable cap on the net cage, floating dish is arranged on the nutrition basin.

Described method is educated to grow in the aphid cocoon honeybee process and can be selected suitable place to move big Tanaka to move net cage, to satisfy conditions such as aphid and aphid cocoon honeybee growth and breeding the most suitable required humidity, temperature, ventilation, implement and educate honeybee with selecting.

Described method can be moved net cage and puts to implement by aphid to the closeest poly-place of aphid and put honeybee.

Described method is after aphid cocoon bee eclosion in the net cage finishes to fly out, and inoculating 10-15 aphid again and changing 40 order gauzes is 60 order gauzes, can occur aphid cocoon honeybee again in 10 days, changes 60 order gauzes into 40 orders again before it is sprouted wings, and allows honeybee fly out and implements and educate honeybee continuously.

Described method is when big Tanaka aphid insect density is excessive, and replaceable gauze 40 orders are 60 orders, shift net cage simultaneously to home, the land for growing field crops applying pesticides aphid of going out, move net cage after 2-3 days again to the plot that still has aphid and to change 60 order gauzes be 40 orders, put the honeybee deinsectization, implement the honeybee medicine and rule together.

Use aphid cocoon honeybee to move net cage control aphid, equipment is light, a people can roll over dress and move operation, it is many to educate the aphid and the aphid cocoon honeybee quantity of growing, the survival rate of honeybee, spawning rate height, can put honeybee, educate honeybee continuously by aphid, throw in and be not subjected to time restriction, the aphid of going out is effective, can avoid the anthropochory of eqpidemic diseases such as powdery mildew, tobacco virus in addition, be a kind of efficient, safety, the easy method of the biological control aphid of row, outside the harm of decapacitation control tobacco aphid, the aphid damages of crops such as rape also had very good preventive and therapeutic effect.

Below be the structure accompanying drawing of mobile net cage:

Fig. 1 is the mobile network box structure schematic diagram that assembles;
