Abstract
The present invention relates to an indoor artificial preservation method of synonycha grandis adults in a wintering period. The method is characterized in that an outdoor wintering environment of the synonycha grandis adults is simulated indoors, a large amount of the synonycha grandis adults in sugar cane fields are collected in late November every year before cold winter and put in the indoor wintering environment, bred by an artificial feed and protected for wintering; the simulated wintering environment is formed by vertically putting 6-8 sections of withered sugar cane sheaths with the length to be 15-20cm in a glass tank with the size that is 18cm is multiplied by 30cm, and arranging a petri dish with the diameter to be 5cm at the tank bottom. The tank is added with absorbent cotton which fully absorbs sugar cane water, and tightly covered with a metal gauze at the opening of the tank. The indoor artificial preservation method of the synonycha grandis adults has the advantages of obviously improving the wintering survival rate of the ladybugs, good preservation effect, effectively and safely protecting wintering for the adult ladybugs, convenient operation and easy mastery. The indoor artificial preservation method is a set of simple and feasible method, and is widely applicable to sugar cane areas.
Description
Technical field:
The present invention relates to the survive the winter artificial protecting method of phase of a kind of big crossette grandis adults.
Background technology:
Sugar cane cottony aphid Ceratovacuna lanigera Zehntner belongs to Homoptera, aphid section, and it is one of primary pest on the sugarcane production, area takes place can reach more than 80% of cultivated area.The general underproduction 13.7%～24.6% of killed sugarcane, the heavy underproduction reaches more than 50%, and sucrose divides content to reduce by 10%～40%.The control sugar cane cottony aphid mainly relies on chemical pesticide at present, because the high malicious broad-spectrum pesticide of long-term use continuously, not only killed and wounded the natural enemy of occurring in nature insect in a large number, destroyed the ecological balance, insect is developed immunity to drugs, and polluted environment, also be easy to cause residue of pesticide in the sugar, harm humans health.Therefore research and development and use advantage natural enemy biological control sugar cane cottony aphid become and produce pressing for of nuisanceless sucrose product, the modern green sucrose industry of development.
Big crossette ladybug Synonycha grandis (Thunberg) belongs to coleoptera, and Coccinellidae is the sociales natural enemy of predation sugar cane cottony aphid Ceratovacuna lanigera Zehntner.Distribute in China and Yunnan sugarcane district wide, population quantity is many, the predation amount is very big, a ladybug can prey on 32000 sugar cane cottony aphids all one's life, is a kind of advantage natural enemy of supporting the protection utilization.But the big crossette ladybug emergence period lags behind woolly aphid under the natural conditions of field, 5～June the woolly aphid initial stage of origination, sugarcane Tanaka ladybug population quantity very little, reproduction speed is slow, 7～August the woolly aphid occurance peak, ladybug to control usefulness naturally very little.Its main cause is: on the one hand the survival rate of surviving the winter of ladybug is low under the natural situation, secondly is that sugarcane is received and destroyed the natural hibernacle of ladybug when cutting artificially, and adding sets fire burns the sugarcane leaf and cause the large batch of ladybug death of surviving the winter.Can therefore, how protect ladybug to survive the winter, improve the survival rate of surviving the winter, when 5～June, the woolly aphid point-like took place, be a large amount of bulk storages of ladybug make good use of the key of this kind natural enemy to the sugarcane field with the purpose that reaches propagation.
Summary of the invention:
The purpose of this invention is to provide the survive the winter artificial protecting method of phase of a kind of big crossette grandis adults, this method can effectively protect ladybug to survive the winter, and improves the survival rate of surviving the winter.
Purpose of the present invention is achieved through the following technical solutions:
According to naturally the survive the winter environment of big crossette grandis adults in the sugarcane field is in the old leaf sheath in sugarcane stem middle and lower part; the present invention is by the environment of surviving the winter in the field of the big crossette grandis adults of lab simulation; a large amount of big crossette grandis adults of gathering sugarcanes ground are put into this environment of surviving the winter before annual late November winter low temperature arrival then, raise with the artificial feed protection and pass the winter.
The field of the big crossette grandis adults of the said lab simulation environment of surviving the winter is: vertically take in diameter 18cm * high 30cm glass jar and put the long sugarcane dead leaf sheath of 6～8 sections 15～20cm, cylinder bottom is put a diameter 5cm culture dish, dress suctions the absorbent cotton of sucrose water, the husky net of the tight-lipped cover of cylinder in the ware.
Said artificial feed are sucrose water+freezing sugar cane cottony aphid, and the preparation method is as follows:
1) with weight is unit, gets 10 parts of running water,, be stirred to dissolving fully, promptly obtain sucrose water to wherein adding 1 part of white sugar with clean container;
2) gather the fresh cane woolly aphid annual October in a large number by the field, add a cover after the culture dish packing with diameter 10cm and place-18 ℃ of refrigerators preservations, promptly obtain freezing sugar cane cottony aphid.
The survive the winter indoors artificial protecting method of phase of described big crossette grandis adults, it is the culture dish that rayon balls is suctioned the hibernacle bottom of putting into simulation behind the sucrose water, the freezing sugar cane cottony aphid of bulk storage around the culture dish, again big crossette grandis adults is put into the inside, 50 in every cylinder, the husky net of the tight-lipped cover of cylinder places indoor 15～20 ℃ of following breeding observings, change a fresh feed in per 3 days, and keep supporting the cleaning of worm cylinder.
Advantage of the present invention and beneficial effect:
1) the present invention can significantly improve the survival rate of surviving the winter of ladybug by at the good environment and provide suitable artificial feed to feed of surviving the winter of indoor construction, and effect of breeds conservation is good, can protect the adult safe overwintering effectively; The adult that preserves survival by this method is got behind the food fresh cane woolly aphid again can fast quick-recovery fertility, in conjunction with transplant help move, artificial propagation, when 5～June, the woolly aphid point-like took place, to the sugarcane field, can very fast propagation set up the growth that huge population can be controlled the sugar cane cottony aphid population well to a large amount of bulk storages of ladybug.
2) the big crossette grandis adults of the present invention Environment Design of surviving the winter is simple, and raw material can be drawn materials everywhere, and it is reusable that glass is supported the worm cylinder, thereby Financial cost is cheap.
3) artificial feed comprehensive nutrition of the present invention is drawn materials everywhere, makes simply with low cost, economical and convenient.
4) survive the winter optimum time of adult of the big crossette ladybug of collection of the present invention is annual late November, can receive in conjunction with sugarcane to divest Lao Ye before cutting and carry out together, saves man-hour, and the effect of getting twice the result with half the effort is arranged.
5) over wintering method of the present invention, handled easily is grasped easily, is the simple and feasible effective ways of a cover, is suitable for extensive use in the sugarcane district.
Embodiment
1, feed preparation
1) preparation of freezing sugar cane cottony aphid: gather the fresh cane woolly aphid annual 8～October in a large number from the field, adds a cover after the culture dish packing with diameter 10cm to place-18 ℃ of refrigerators to preserve to gather the fresh cane woolly aphid standby October in a large number to the field; Ready access upon use.
2) sucrose water preparation: with weight is unit, gets 1 portion of white granulated sugar with clean container, adds 10 parts of water, is stirred to dissolving fully, promptly obtains sucrose water; With using with joining.
