Description

The cover bag cultivation method of plant-feed insect

Technical field

The invention belongs to the cover bag cultivation method of a kind of plant-feed insect.

Background technology

Many insects have special practical value, but wild insect resources is difficult to control and utilization, needs through propagating artificially, and taking on a certain scale just has practical significance.Be grown in as butterfly, silkworm, secret numb silkworm, locust etc. and be difficult on the parasitic plant collect; Artificial feeding to insects such as silkworms is manually to pluck mulberry leaf to concentrate the raising that feeds intake now, both wastes time and energy, and effect is indefinite uncertain good, because larva eats less than fresh blade, growth differs and reserves.Put in a suitable place to breed on certain parasitic plant if adopt, meet with natural enemy crow, worm and sick infringement again unavoidably, the larva survival rate is low, and culture efficiency is poor.

Summary of the invention

Purpose of the present invention is exactly at the problems referred to above, proposes a kind of plant-feed insect cover bag cultivation method, makes the insect that parasitizes on the fresh and alive plant avoid the natural enemy infringement, be convenient to control and management, improves efficient and the level of artificial feeding insect with this.

The cover bag cultivation method of this plant-feed insect that the present invention proposes is characterized in that comprising the steps:

(1) selected insect larvae is placed on the branches and leaves of institute parasitic plant and be fixed on the bar or soil together with the branches and leaves jacket with ventilative bagging;

(2) according to the situation of blade that insect eats in the bagging and tender shoots, in good time with insect and bagging dislocation on new branches and leaves, not jejunitas to guarantee insect, allow the branches and leaves of eating grow again simultaneously, in order to circulation.

Used bagging is nylon net bag, gauze bag, hemp bag etc., and the mesh size of bagging is 0.5-2mm.

The fixed form of bagging and parasitic plant is for rope is pricked, ring presss from both sides or imbed in the soil sack fixing.

According to the insect growth situation, adjust the quantity of insect in each bagging in good time.Larva grows up to can move behind pupa or the adult to be put in a suitable place to breed outside bagging or utilizes.

To host plant ridging, loose, weeding, fertilising and irrigation, keep the essential growth impetus of plant in good time.

In the bagging breeding process, also on bagging, put plastic sack according to weather condition when rainy season or the low temperature, so that rainproof winter protection.

Want timely wash clean with the bagging of crossing, the airing sterilization is standby.

Characteristics of the present invention are to utilize the characteristic of insect's food-taking live plant, be isolated in certain ventilated closed space raising insect, build a unapproachable growing environment of extraneous natural enemy, thereby the assurance insect larvae is grown up smoothly, be convenient to when running into disease to wherein discharging the medicine mist, treatment in time, thus improved the larva survival rate, quickness and high efficiency when collecting adult is convenient to control and management to scale and quality.

Further specify good effect of the present invention with example below.

Embodiment

Example 1 is supported butterfly, and the chief value of butterfly is to view and admire.Let butterfly with different colors fly away in the celebration occasion, can build happy and auspicious atmosphere, increase celebrating color; Also can make sample or handicraft, carry out commercial development.Selected butterfly kind larva manually is displaced to the host plant that their happinesses are eaten, and on the branches and leaves as trees such as shaddock, oranges and tangerines, birthworts, the bagging made from nylon net cloth is surrounded larva place branches and leaves, and the sack gathering is tightened with cord and is fixed on the branch.Sack is changeable, and size does not wait from length and width 20-30cm to 40-100cm, and shape can be long tubular, infundibulate, ellipse, can justify.The quantity of throwing in insect in each bagging only arrives 3-5 less, and 10-100 does not only wait at most.Along with growing up of larva, quantity also should in time be adjusted in the bag, can both in time have fresh blade to guarantee every insect.Generally nibble situation, change bag and shift, guaranteeing that enough edible fresh blades are arranged in the bag, and allow the branches and leaves of eating regrow according to blade in the bag.Just can gather in the crops the butterfly pupa to bagging of a kind.

The mesh size 0.5-2mm of nylon net cloth is fit to.The dimensional requirement of mesh can't get out can satisfy larva, and the natural enemy worm advances not go with ventilated for principle.The material of bagging can also be gauze, plastics screen cloth, the linen fabrics even screen window net, replaces to another kind of material from a kind of material and there is no substantial differences, can both allow larva grow up smoothly, reaches purpose of the present invention.

Between feeding period, apply fertilizer in good time, water, spray Routine Managements such as diseases prevention insect protected agricultural chemicals to host plants such as grapefruits, to guarantee the growing way of host plant.

It approximately is 20 days that this example is supported the butterfly cycle.Through 20 batches raising, find no natural enemy and advance the bag infringement, the survival rate of average every batch of breeding grub reaches more than 99%.

Example 2 is cultured eri silkworm, and eri silkworm silk can be widely used in the production of various clothes, silk fabric, and pupa or larva can produce high-grade protein feeds, and the worm excrement is first-class organic manure.During breed, according to the castor-oil plant branches and leaves what, select suitably big bagging and an amount of young instar as above example equally overlap and support on the castor-oil plant tree branches and leaves.Raise the change pupa that spins of just weaving silk through 30-35 days baggings, select fine results.In the way, eaten 90% o'clock, in time changed bag, in order to avoid larva is hungry to death as leaf.

Example 3 is cultured silkworm, and the silkworm cultural technique is similar to the breed eri silkworm.Be nothing but silkworm larvae to be placed on the mulberry tree branches and leaves with bagging raise, breeding process and management are with example 2.Through 20 batches raising, survival rate reaches more than 99%, and income is obvious.

Example 4 is cultured walkingstick, and walkingstick is the insect of incomplete metamorphosis, and according to the kind difference, worm is long not to be waited from 10-35cm, is the raw material that teaching, scientific research and sample handicraft are made.Cultural method is cultured similar to eri silkworm.Through 20 batches breed, also find natural enemy and disease, survival rate is more than 99%, and benefit is better.

Example 5 is cultured locust, and locust also belongs to plant-feed insect, is high-protein food, and all there is the custom of edible locust various places, China south, and the can of also making that has is sold in the supermarket.Locust belongs to the incomplete metamorphosis insect, cultivate the vigorous grass family host plant of growing way during breed earlier, length will definitely be made at 1-5m, 1-5m, 1-1.5m square or rectangular bagging by nylon net bag in the base area, the top is stayed the 10-20cm movable window and is put larva in a suitable place to breed and collect adult so that observe, support is made with bamboo or reinforcing bar in the inside, during breed, bagging is entangled host plant, the below of bag is buried tight with earth, in case locust runs away.This technology is through 20 batches raising, and survival rate is more than 99%, and adult is the restaurant delicacies, and the market price is very high.
