CN103348953A - Method for breeding grandis by using callosobruchus chinensis - Google Patents

Abstract

The invention relates to application of callosobruchus chinensis larva to artificial breeding of grandis as a living feed. The callosobruchus chinensis has strong fertility (the environment is suitable and 11 generations can be bred), the feeding is wide and low in cost (such as mung bean, small bean and cowpea), the propagation technology is easy to operate, and the living feed for large-scale propagation of the grandis is easy and convenient to obtain. Artificial large-scale breeding of the grandis can be realized. The method is used for treating red turpentine beetle pests.

Description

Utilize adzuki bean weevil to breed the method for large swallow wax first

Technical field

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

Background technology

Red turpentine beetle claims again red turpentine beetle, is the external Harmful from the North America.Qinshui County in China Shanxi Province, Yangcheng County were found first in 1998, were domestic New Records.This worm main harm diameter of a cross-section of a tree trunk 1.3 meters above the ground is at trunk and the master root of the above pine tree of 10cm, and the stump of fresh Chinese pine, lumbering, invade the position many at butt to the 1m place.With adult or larval feeding phloem, form layer., be injured position large when insect density links to each other when forming band girdle, can cause whole tree dead.The end of the year 1999, this worm in Shanxi, Hebei, Henan San Sheng in succession large tracts of land occur, calendar year 2001, Shaanxi Province also found this worm harm, to the end of the year 2004, area 16.2 ten thousand hm2 occur in the whole nation altogether, and local environment, economic development and afforestation achievement have been caused massive losses.Existing technology all is to catch and kill red turpentine beetle with chemical agent, but has the defective of contaminated environment.

Large swallow wax first is the natural enemy insect of red turpentine beetle, utilizes the natural enemy insect Control pests, and is both free from environmental pollution; safeguarded the ecological balance; having protected bio-diversity, made again insect obtain Sustainable Control, is the most effectual way of controlling at present red turpentine beetle with future.But prior art is to adopt red turpentine beetle to breed large swallow wax first as feed, because the breeding feed of high-quality is difficult to acquisition, so that the industrialized development of large swallow wax first is obstructed seriously.

Summary of the invention

Technical problem solved by the invention at first provides the adzuki bean weevil larva as the application of live body feed in the large swallow wax of artificial breeding first.Adzuki bean weevil fertility strong (environment can occur in suitable 1 year 11 generations) takes food extensively and cheap (mung bean, red bean and cowpea etc.), and the propagation technique easy operating obtains easy as large swallow wax first vast propagation live body feed.With its live body feed as large swallow wax first, can realize manually breeding on a large scale of large swallow wax first.

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

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

Concrete embodiment can be:

(1) raising condition: room temperature is 20 ± 2 ℃, and humidity is 70 ± 5%;

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

(3) raising of larva: after ovum is hatched into small grub, be allowed to condition in the cultivation box and take food the adzuki bean weevil larva; Begin to count from the ovum hatching, after about about 20 days, larva is aging;

(4) larvae pupation: gather mature larva and put into the sterilized sand of the 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 that will newly sprout wings carries out captive breeding, put under 7-10 ℃ the low temperature refrigeration about 30 days.

The present invention utilizes the adzuki bean weevil larva as the live body feed of large swallow wax first, adzuki bean weevil fertility strong (environment can occur in suitable 1 year 11 generations), take food extensive and cheap (mung bean, red bean and cowpea etc.), the propagation technique easy operating obtains easy as large swallow wax first vast propagation live body feed.Can realize that large swallow wax first manually breeds on a large scale.In order to treat the red turpentine beetle insect pest.

Embodiment

For further specifying the present invention, specify with the following Examples:

Embodiment 1:

The method of the large swallow wax of a kind of artificial breeding first comprises step:

(1) raising condition: room temperature is 20 ± 2 ℃, and humidity is 70 ± 5%;

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

(3) raising of larva: after ovum is hatched into small grub, be allowed to condition in the cultivation box and take food the adzuki bean weevil larva to 2 ages, then it is shifted out to be placed in the rectangular flask that is placed with sawdust and feed with the adzuki bean weevil larva; The height that sawdust is placed is distance large inside edge top 8mm; Add fresh feed (parasitism has the mung bean of adzuki bean weevil) every day, and will eat feed surplus or that rot and take out; Begin to count from the ovum hatching, after about about 20 days, larva is aging;

(4) larvae pupation: gather mature larva and put into the sterilized sand of the 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 that will newly sprout wings carries out captive breeding, put under 7-10 ℃ the low temperature refrigeration about 30 days.
