Description

Method for directionally breeding high-temperature resistant corpus luteum strain of gelechiid smith
Technical Field
The invention relates to the technical field of insect breeding, in particular to a method for directionally breeding a corpus luteum high-temperature-resistant strain of a hornworm molossus.
Background
A Choristoneura braconica Hebetor, latin name Habrobracon hebetor, is an insect belonging to the genus Choristonella of the family Hymenoptera braconidae, widely distributed in China and all over the world, and belongs to a parasitic insect. The bracon hebetor can parasitize larvae of various lepidoptera insects such as coco moths, cotton bollworms and the like, and is used for controlling related pests.
Female hornworm of hornworm: brown yellow body and black antenna; the single-eye area, the back head, the middle part of the face, the middle chest back plate, the middle chest side plate and the chest-abdominal joint are dark brown; transparent wings, semi-dark brown base, and wing nevi and wing veins. Abdomen 3, back plate and back plate are yellow brown; the sheath is dark brown. Males are female-like, with elongated tentacles, and the 1 st segment of the flagellum is slightly longer than the 2 nd segment. The abdominal parts 1 and 2 (except the arched triangular part of the section 1) are gray yellow. The adult body color of the gelechiid smith shows brown yellow, the body color is uneven, and the gelechiid smith has mixed colors, so that no relevant report about breeding of the luteal gelechiid smith is found at present.
Research shows that the parasitism rate of the bracon hebetor is closely related to the temperature, the parasitism rate is higher in the range of 26-29 ℃, and when the temperature is further increased, the parasitism rate is reduced. For example, dianbaozhu et al studied the paralytic and parasitic effects of the Choristoneura heterospodum on 5 th larvae of Indian meal moth at different densities in the room at 17, 23, 26, 32 and 35 ℃. The results show that: the host processing time of parasitic wasps is inversely proportional to temperature in the range of 17-29 deg.c. The host search rate also varies with temperature
Lowest at 17 ℃ and highest at 29 ℃; when the temperature is increased to 32-35 ℃, the host search rate is reduced again. Therefore, strict temperature control is required for propagation of the hornworm molossus in production. However, the southern area of China has high temperature all the year round, so the characteristic of the hornworm of the wheat moth which can not resist high temperature restricts the popularization and the application of the hornworm of the wheat moth in the southern area. In view of the above, there is a need for further breeding of a high temperature resistant strain of hornworts maid. At present, the breeding work of the high-temperature resistant strains of the hornworts has not been effectively progressed, and no relevant report is found.
Disclosure of Invention
In view of the defects of the prior art, the application provides a method for directionally breeding a high-temperature resistant corpus luteum strain of the hornworm molossus.
The scheme of the invention is as follows:
a method for directionally breeding a high-temperature resistant corpus luteum strain of a Choristoneura heterospodum comprises the following steps:
feeding the adult hornworm molocos into a nutrient solution containing an L-tyrosine solution, parasitizing to obtain offspring, and treating the offspring of the pupal stage hornworm molocos at 30-32 ℃ to obtain the corpus luteum high-temperature-resistant strain of the hornworm molocos.
Preferably, the nutrient solution containing the L-tyrosine solution is a sugar source containing L-tyrosine.
Preferably, the nutrient solution containing the L-tyrosine solution is honey water containing L-tyrosine.
Preferably, the mass ratio of L-tyrosine, honey and water in the nutrient solution is 1-5.
Preferably, the mass ratio of the L-tyrosine to the honey to the water is 1.
Preferably, the treatment time at 30 to 32 ℃ is 48 to 72 hours.
Preferably, the method for directionally breeding the high-temperature resistant corpus luteum strain of the gelechiid braconidae comprises the following steps:
feeding the hornet mollissima into honey water mixed with L-tyrosine, parasitizing to obtain offspring, and treating the hornet mollissima offspring in the pupal stage at 30 ℃ for 48 hours to obtain the high-temperature resistant strain of the corpus luteum of the hornet mollissima.

the invention firstly utilizes honey water mixed with L-tyrosine to feed the gelechiid braconid wasps to form the adult wasps, opens a regulation and control path, and then further carries out treatment for 48 to 72 hours at 30 to 32 ℃ in the pupal stage of offspring. Under the comprehensive action of the steps, the high-temperature resistant corpus luteum strain of the wheat moth bombyx batryticatus is obtained. The high-temperature-resistant wheat moth cocoon bee strain can be propagated at a higher temperature, the indoor and outdoor parasitic rates are obviously higher than those of common strains, and the unique golden yellow body color enables the high-temperature-resistant strain to have obvious specificity compared with the common strains, so that the strain is easier to distinguish and is beneficial to the identification of the strain.
The high-temperature resistant strain bred by the method disclosed by the invention can be more suitable for high-temperature climate, and the efficiency of preventing and controlling the palm pests, namely coconut leaf moths and the like, in Hainan is higher.
The method disclosed by the invention is simple and convenient to operate, does not need expensive instruments or reagents, is low in cost and short in treatment time, and can be used for stably obtaining the corpus luteum high-temperature-resistant strain of the hornworm molossus within a short period of time.

In order to better understand the technical content of the invention, specific examples are provided below to further illustrate the invention.
Example 1 method for directionally breeding high-temperature resistant luteal strain of gelechiid smith
The adult hornets were fed with honey water mixed with L-tyrosine (L-tyrosine: honey: water = 1. Propagating the gelechiid moths soft cocoon bee by using the gelechiid moths as hosts, and treating the gelechiid moths soft cocoon bee by using 30 ℃ (the relative humidity is 60 +/-10%) for 48 hours in the pupation stage of the gelechiid moths soft cocoon bee seeds to obtain high-temperature resistant offspring gelechiid moths soft cocoon bee with yellow body color.
Comparing the high temperature resistant strain with the non-high temperature resistant strain before breeding, the new strain bred has golden body color, less and light mixed color, and the strain before breeding has obvious yellow brown or black body surface and more mixed color. (FIG. 1)
Test example: high temperature resistance capability test of different gelechiid braconid beetle strains
The indoor test procedure is carried out according to the influence of different hosts on the parasitism, development and propagation of the hornet of the Maifand moth (Chen Yunlei, yan Sanqiang, lvbouqiang, luhui, tang-Secondary flood and Wangchong). The host is coconut fruit moth.
And (3) field test: the indoor propagation of the imagoes of the gelechiid braconid moths is carried out according to the bee-keeping quantity of 12000 heads/hm 2 Releasing bees twice at an interval of 7 days, and keeping the average temperature above 30 ℃ during releasing bees. The plant species planted in the test field and the cultivation management mode thereof are the same. The number of the larvae of hundreds of coconuts and the moths in the field is investigated once before the bees are put, each treatment is divided into 3 districts, each district is investigated for 5 points, and each point is investigated for 10 plants. For the second timeAnd 7 days after the bees are placed, bringing the larvae back indoors for observation, counting the parasitic quantity of the pests, and calculating the parasitic rate.
And comparing the parasitic rates of the high-temperature resistant strain and the non-high-temperature resistant strain, wherein the result shows that the indoor and outdoor parasitic rates of the high-temperature resistant strain are obviously higher than those of the control strain. (see table below).
