Problems solved by technology

Tung geometrid black egg wasp (Telenomus buzurae Wu et Chen) belongs to the genus Leptosperidae and is an egg parasitic insect. It is currently found to be a better dominant parasitoid for tung geometrid pests, but there is currently a lack of large-scale breeding of Tung geometrid black eggs. Related research on egg bees

Embodiment 1

[0030] A kind of breeding method of tung looper black egg bee, comprises the steps:

[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 rope, and the other end of th...

[0064] Experimental example 1: Fresh-keeping experiment of eucalyptus leaves

[0065] 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:

[0066] 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.

[0067] 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.

[0068] 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 ...

[0072] Experimental example 2: The tendency test of the tung looper to the egg collection device

[0073] 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.

[0074] Table 2

[0075] 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

[0076] 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 agricultural pest biological control, and discloses a tung tree inchworm black egg bee breeding method which comprises the steps of tung tree inchworm breeding, tung tree inchworm black egg bee parasitism and tung tree inchworm black egg bee batch breeding. Enabling the tung tree inchworm black-egg bees to parasitize in tung tree inchworm eggs, and performing batch breeding of the tung tree inchworm black-egg bees after eclosion of the tung tree inchworm black-egg bees. According to the method, the tung oil tree inchworm eggs are used for breeding the tung oil tree inchworm black egg bees on a large scale, when the tung oil tree inchworm pests occur, the tung oil tree inchworm black egg bees are released to forest areas where the tung oil tree inchworm pests occur, 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 looper black egg bee. 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 recent ye...
