A kind of method utilizing wasp to prevent and treat phyllocnistis citrella stainton
Technical field
The invention belongs to technical field of biological control, be specifically related to a kind of method utilizing wasp to prevent and treat phyllocnistis citrella stainton.
Background technology
Wasp, has another name called hornet, is the one of wasp, and be the general designation of Vespoidea in Hymenoptera (Hymenoptera) apocrita, it is mainly distributed in the jungle in south China mountain area.There will be a known kind more than 5000 in the world, what China recorded has more than 200 to plant, very wide at distribution in China.
Wasp adult, larva and honeycomb can enter Chinese medicine.Honeycomb can make traditional Chinese medicine, has analgesic therapy, expelling parasite, subdhing swelling and detoxicating effect, cures mainly frightened epilepsy, wandering arthritis, acute mastitis, toothache, stubborn dermatitis, cancer etc.Wasp wine is dispelled rheumatism, and controls anxious, slow rheumatalgia, the good medicine of rheumatic arthritis.Wasp poison can treatment of arthritis, and medical value is high, has great significance to the research and production of medical new product.
Along with improving constantly of expanding economy and people's living standard, delicious food, nutrition, health care, regress into nature have become the fresh target that people pursue, so the favor that those have special dietary, the special animals of special value is more subject to people, dense as game, nutritive value is complete, the wasp pupa that medication effect is high, becomes the new fashion that people consume.At present, wasp product is extensively come in the life of people, becomes the consumption kind of people's first-selection.China is populous, and consumption market is wide, and particularly the market demand such as Guangzhou, Taiwan, Hong Kong, Guangxi, Beijing, Shanghai is larger, and therefore, hornet has become the best-selling item in a kind of game commodity, and only supply falls short of demand in the market such as Taiwan, Guangzhou, Guangxi.
Phyllocnistis citrella stainton, belong to Lepidoptera, leaf mining lyonetid section (Phyllocnisidae), is distributed in Jiangxi, the areas such as Jiangsu, Fujian, Zhejiang, Hainan, Guangxi, Guangdong, Hunan, Hubei, Guizhou, Sichuan, Chongqing, Shanghai.The flowers and trees such as harm oranges and tangerines, kumquat, lemon, eryuelan, structure tangerine, calamondin.It is a kind of important pests of south China citrus.Larva leaf mining is caused harm young shoot tender leaf, causes sinuous tunnel, killed leaf curl, is easy to come off, and lead to the generation of canker.
About within 1 year, can there are for 10 generations, survive the winter on killed leaf with pupa and larva.The most summer shoot from early June of phyllocnistis citrella stainton is taken out to send out and is started harm, and the autumn growth continuing up to early October is aging, contains most again with harm in 8 ~ September.Can be there are 12 generations more than in southern areas year in this worm, about the generation of northern territory 8 ~ 9, generation overlap, survives the winter in autumn and winter tip leaf margin convolution mainly with pupa.Leaf miner adult is without the light that becomes, chemotaxis, inhabit daytime in the interior blade back of hat and orangery weeds clump more, early morning and evening 8 ~ 10 time frequent activity, female moth by ovum fecund on tender leaf Zhong Mai both sides or spray, every leaf number of eggs laid grain to 20, eat into after larvae hatch into blade or the harm of tender tip epidermis moth food, form the bending gallery of white.If the Sheng phase that leaf miner occurs and oranges and tangerines summer, autumn growth are taken out in a large number to send out and matched, endanger often serious; Nursery stock and treelet many and irregular owing to taking out the tip, be beneficial to Adult worms producting eggs and larva harm, be injured also more serious.Affect the factor that leaf miner occurs in a large number and mainly contain climatic factor, natural enemy factor and food factor.The optimum temperature that breeding occurs phyllocnistis citrella stainton is 24 ~ 28 DEG C, relative moisture about 80%.After larva harm tender leaf, spray, make leaf rolling firmly crisp and come off, young sprout growth retardation, affect tree vigo(u)r and take out tip result, the wound of larva harm is beneficial to again the intrusion harm of the damage by disease and insect such as canker and mite class
Wasp is predatism honeybee class.According to research reports, the province such as Henan China, Shanxi takes human assistance to survive the winter and human assistance is built nest and moved the method for nest, utilizes wasp to prevent and treat cotton-plant pest-insects, very effective, and both economical.Put into cage catching queen bee after autumn, cage is placed in wind sheltering place, lets alone to unite, to next spring, these queen bees are put into field, let alone naturally to nest around field.Also can provide food, drinking-water and construction material in large honeybee canopy, make it at the built-in nest of canopy.When needed, nest is moved to field, every mu of 3 ~ 5 nests, have honeybee 100 remainder, can the causing harm of basic controlling lepidoptera pest.Because wasp goes back to the nest habit, so it is once permanently effective to put honeybee.Its feeding habits are wide, can prevent and treat multiple agriculture and forestry injurious insect.But there are no wasp being used for the relevant report of preventing and treating oranges and tangerines Liriomyza in document.
Summary of the invention
