Embodiment 1

[0030] A kind of breeding method of the tung inchworm long-striped Acanthus tungii, comprising the steps of:

[0031] Step I: Land consolidation and eucalyptus seedling colonization management

[0032]Select a piece of land with relatively gentle terrain, and use nitrogen, phosphorus and potassium compound fertilizer and decomposed organic fertilizer as base fertilizer for deep plowing of the land. Plant a row of eucalyptus seedlings at an interval of 1.2 meters, and control the plant spacing of each row to be 1.2 meters. Dig a trench with a depth and width of 500*600 between each row, and plant the excavated soil on the roots of the eucalyptus seedlings, which is beneficial for later fertilization and irrigation.

[0033] After planting, fill the seedlings according to the survival of the eucalyptus seedlings. After one year of growth, the eucalyptus seedlings will reach a height of 6-8 meters, and the tops will be cut off. The top of the eucalyptus is tied with a nylon rop...

[0063] Experimental example 1: Fresh-keeping experiment of eucalyptus leaves

[0064] Eucalyptus leaves are mainly fed by tung loopers. In order to prolong the preservation time of eucalyptus leaves, different treatments are carried out on eucalyptus leaves. The treatment methods are as follows:

[0065] Treatment group 1: put eucalyptus shoots with fresh young leaves in dry glass, and place them in tung looper breeding cages, control indoor light L:D=16:8, temperature 25±3°C, humidity 75°C ±5%, observe the preservation days and leaf fall time.

[0066] Treatment group 2: put eucalyptus twigs with fresh young leaves in dry glass, seal with plastic sealing film, and place them in tung looper breeding cages, control indoor light L:D=16:8, temperature 25 ±3°C, humidity 75±5%, observe the preservation days and leaf fall time.

[0067] Treatment group 3: put the eucalyptus twigs with fresh young leaves in a water cup, and place them in a tung looper breeding cage, control indoor ...

experiment example 2

[0071] Experimental example 2: The tendency test of the tung looper to the egg collection device

[0072] Experimental design: put different egg-collecting objects in the breeding cages, and the adults of Tungia tungii can complete mating and lay eggs within 48 hours after eclosion. After 48 hours, observe and record the number of egg masses, egg grains and distribution on each egg-collecting device shape.

[0073] Table 2

[0074] serial number Egg collection Number of egg blocks / block egg / grain Distribution shape 1 Nylon gauze 3 4400 dense + scattered 2 Corrugated paper egg collecting device 86 44200 Scattered bands 3 Eucalyptus branches / leaves 13 8600 dense strip 4 Auxiliary device plastic case 5 2700 dense round shape 5 Agricultural film 2 660 dense round shape

[0075] As can be seen from the data in Table 2, what serial number 2 adopted is a corrugated paper egg collection device, and the corrugated...

Abstract

The invention relates to the field of biological prevention and control of agricultural pests, and discloses a method for breeding tung tree inchworm microdiplodia variabilis, which comprises the steps of breeding tung tree inchworm, parasitizing tung tree inchworm microdiplodia variabilis and breeding tung tree inchworm microdiplodia variabilis in batches. The method comprises the following steps of: parasitizing the tung tree inchworm diplodia variabilis on the body surfaces of larvae of the tung tree inchworm, and carrying out batch breeding on the tung tree inchworm diplodia variabilis after the tung tree inchworm diplodia variabilis parasitizes. According to the method, the tung oil tree inchworm larvae are used for large-scale breeding of the tung oil tree inchworm long-distance agaricus bisporus, when the tung oil tree inchworm larvae occur, the tung oil tree inchworm larvae are released to the forest area where the tung oil tree inchworm damage occurs, and green prevention and control are achieved.

Description

technical field [0001] The invention relates to the field of biological control of agricultural pests, in particular to a breeding method for the tung inchworm Adenophora longis. Background technique [0002] Buzura suppressaria Guenee, also known as Buzura suppressaria Guenee, is one of the important pests of forest industry in my country. There are 3-4 generations of this worm a year, and the overlapping phenomenon of each instar is serious. The tung looper has strong fecundity and large food intake for larvae, causing damage by gnawing on the leaves of crops. When it occurs in a large area, the entire forest leaves will be eaten up, just like a fire, which makes the trees unable to carry out photosynthesis normally, directly threatening the growth and development of the trees. Survive. Tung looper damages hosts such as tung tree, eucalyptus, camellia oleifera, tea tree, citrus, loquat and other plants, and it is often rampant intermittently in summer and autumn. In rec...
