Description

Adzuki bean weevil is utilized to breed the method for large swallow wax first

Technical field

The present invention relates to insect and raise field, especially relate to large swallow wax first mass rearing technology.

Background technology

Red turpentine beetle, also known as red turpentine beetle, is the Workers from outside from North America.Qinshui County in Shanxi Province of China in 1998, Yangcheng County Late Cambrian are domestic studies.This worm main harm diameter of a cross-section of a tree trunk 1.3 meters above the ground at the trunk of more than 10cm pine tree and master root, and the stump of fresh Chinese pine, lumbering, infestation position many at butt to 1m place.With adult or larval feeding phloem, form layer.When insect density is comparatively large, the position that is injured is connected to form band girdle, whole tree can be caused dead.The end of the year 1999, this worm in Shanxi, Hebei, Henan San Sheng in succession large area occur, Shaanxi Province also found that this worm endangers, to the end of the year 2004 calendar year 2001, the whole nation is occurring area 16.2 ten thousand hm2 altogether, causes massive losses to local environment, economic development and afforestation achievement.Existing technology is all catch and kill red turpentine beetle with chemical agent, but there is the defect of contaminated environment.

Large swallow wax first is the natural enemy insect of red turpentine beetle, utilizes natural enemy insect Control pests, both free from environmental pollution; maintain the ecological balance; protecting bio-diversity, make again insect obtain and continue to control, is control the most effectual way of red turpentine beetle with future at present.But prior art adopts red turpentine beetle to breed large swallow wax first as feed, and the breeding feed due to high-quality is difficult to obtain, and makes the industrialized development of large swallow wax first be obstructed seriously.

Summary of the invention

First technical problem solved by the invention is to provide adzuki bean weevil larva as the application of life food in artificial breeding large swallow wax first.Adzuki bean weevil fertility strong (environment is suitable can occur in 1 year 11 generations), take food extensively and cheap (mung bean, red bean and cowpea etc.), propagation technique is easy to operation, obtains easy as large swallow wax first vast propagation life food.It can be used as the life food of large swallow wax first, the artificial of large swallow wax first can be realized and breed on a large scale.

Adzuki bean weevil larva of the present invention is artificial propagation in scale.

The present invention further provides the method for a kind of artificial breeding large swallow wax first, it is with the life food of adzuki bean weevil larva as large swallow wax first.

Concrete embodiment can be:

(1) rearing conditions: room temperature is 20 ± 2 DEG C, humidity is 70 ± 5%;

(2) raising of adult: cultivate in box in circle the sawdust placing 2/3, sawdust distilled water is mixed wet, and humidity is not can squeeze water droplet with hand; In sawdust, place the parasitic mung bean having adzuki bean weevil, at least comprise the large larva of 10-15 head adzuki bean weevil or 20-30 head adzuki bean weevil small grub, then place 10 large swallow wax first male imagos and 10 large swallow wax first female adult pest, then cover lid, be put in dark place; Adult will take food adzuki bean weevil larva and lay eggs;

(3) raising of larva: become after small grub until egg hatching, is allowed to condition in cultivation box and takes food adzuki bean weevil larva; Count from egg hatching, after about about 20 days, larva is aging;

(4) larvae pupation: gather mature larva and put into the sterilized sand of box of pupating, allow it pupate, the water content of sand is 9%, and after about about 45 days, the adult of emergence climbs out of sandbox, collects;

(5) cold acclimation of adult: before the adult newly sprouted wings is carried out captive breeding, refrigerates about 30 days under putting into the low temperature of 7-10 DEG C.

The present invention utilizes adzuki bean weevil larva as the life food of large swallow wax first, adzuki bean weevil fertility strong (environment is suitable can occur in 1 year 11 generations), take food extensively and cheap (mung bean, red bean and cowpea etc.), propagation technique is easy to operation, obtains easy as large swallow wax first vast propagation life food.Large swallow wax first can be realized manually breed on a large scale.In order to treat red turpentine beetle insect pest.

Embodiment

For further illustrating the present invention, illustrate with the following Examples:

Embodiment 1:

A method for artificial breeding large swallow wax first, comprises step:

(1) rearing conditions: room temperature is 20 ± 2 DEG C, humidity is 70 ± 5%;

(2) raising of adult: cultivate in box in circle the sawdust placing 2/3, sawdust distilled water is mixed wet, and humidity is not can squeeze water droplet with hand; In sawdust, place the parasitic mung bean having adzuki bean weevil, at least comprise the large larva of 10-15 head adzuki bean weevil or 20-30 head adzuki bean weevil small grub, then place 10 large swallow wax first male imagos and 10 large swallow wax first female adult pest, then cover lid, be put in dark place; Adult will take food adzuki bean weevil larva and lay eggs;

(3) raising of larva: become after small grub until egg hatching, is allowed to condition in cultivation box and takes food adzuki bean weevil larva to 2 ages, then shifted out in the rectangular flask being placed on and being placed with sawdust and feed with adzuki bean weevil larva; The height that sawdust is placed is apart from large inside edge top 8mm; Add fresh feed (parasitism has the mung bean of adzuki bean weevil) every day, and take out eating feed that is surplus or that rot; Count from egg hatching, after about about 20 days, larva is aging;

(4) larvae pupation: gather mature larva and put into the sterilized sand of box of pupating, allow it pupate, the water content of sand is 9%, and after about about 45 days, the adult of emergence climbs out of sandbox, collects;

(5) cold acclimation of adult: before the adult newly sprouted wings is carried out captive breeding, refrigerates about 30 days under putting into the low temperature of 7-10 DEG C.

Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that the common engineers and technicians in this area make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
