Description
Technical Field
The invention relates to the field of pest control, and particularly relates to a control method of pinkeye.
Background
The Korean pine is a rare and rare tree species and has great economic value. In the Korean pine artificial forest of Heilongjiang province, the Brachydia (Dioryctria) species pests seriously damage cones and branches and tips, and are easy to be confused due to large variation of the internal and external forms of the species and very similar external forms and life habits among the species. The pests have hidden life and irregular development, and no effective control measures exist at present. Pests damaging the tips of red pine fruits in Heilongjiang province mainly comprise red pine tip yellow borer (D.sylvestrella) and fir tip yellow borer (D.abietella), wherein the former pests usually have one fruit and one worm, the damage is transferred between the fruit and the tip, and the damaged fruit has much fat but is not rotten; the latter has the disadvantages of more insects in one fruit, no transfer and harm to habit, and easy decay of the damaged fruit.
The pink borer (Diorysteria mongolica Wang & Sung) mainly occurs in young groves and red pine forests of the pinus sylvestris and is a destructive trunk-boring pest of the pinus sylvestris and the red pine. The rare damage to pinus sylvestris in the original forest of great Khingan at the end of the last 70 th century is spread to artificial forests of pinus sylvestris and pinus koraiensis at the beginning of the century. The pest has hidden life, and when the forest is slightly damaged, the symptom is not obvious, so that the pest is not easy to be found, and the prevention and control difficulty is high. The insect can prevent the transportation of water and nutrients in forest trees by eating the insects at the edge of phloem and xylem with larvae, so that the trunk and side branches are greased, and the trunk is full of large and small coagulated fat masses mixed with brown excrement when the insects are serious. The larvae can move in the sticky molten wax-like clotted fat mass, frequently come in and go out between the wormholes and the clotted fat mass, and have the habit of transferring harm. Causing the young trees to wither, wind break of the trunk and the lateral branches, and wind break and head break of the lateral branches of the big trees. The damaged trees affect the growth if the trees are light, the ratio of the grown trees to the finished trees is reduced, and the incomplete forest is caused; the serious people cause the death of a large number of trees, and bring destructive harm to the artificial forest of the pinus sylvestris and the pinus koraiensis. The pinworm occurring in the red pine forest is harmful to branches and tips, and also to the pinworm spot borer which is harmful to cones, mainly to the pinworm spot borer (d.sylvestrella), the pinworm spot borer (d.abietella), the pinworm spot borer (d.rubella), and the like, which cause malformation distortion of cones, or withering due to dry shrinkage, poor seed recovery, withered and broken branches, and seriously affect the fructification and growth of trees. Because the larvae and pupae of the pinworm ostrinia nubilalis live hidden life, eggs are small and scattered, are not easy to be found, the life history is irregular, the difficulty is increased for the prevention and treatment work, and the damage is not enough to be controlled only by chemical prevention or a single prevention and treatment mode. Therefore, the prevention and treatment policy of 'prevention is taken as a main part, scientific treatment, legal supervision and responsibility enhancement' must be adhered to, and the comprehensive treatment measures of forest-cultivation technical measures, biological control, physical control, chemical control and the like are adopted, so that the propagation and serious harm trends of the disease can be effectively controlled.

3) in the second year, the damaged part of the tree is pruned or the coagulated grease mass is manually removed, then the pesticide is injected or sprayed, and meanwhile, the larva which is eaten into the trunk part is prevented and controlled by a tree trunk part punching and pesticide injection method.
The invention has the following beneficial effects:
according to the scheme, in the process of preventing and controlling the pinworm, forest investigation is combined, the pinworm is prevented and controlled in a targeted manner according to the investigated structure, and the effect of achieving twice the result with half the effort is achieved. But also can treat the pinkeye thoroughly. The method of the invention is used for preventing and controlling the pinworm porphyrapha nubilalis in the red pine growing area of the great khingan area, and the result shows that the average reduction rate of the pinworm porphyrapha nubilalis in the peak period of preventing and controlling the adult pinworm porphyrapha nubilalis in the current year reaches about 98 percent. The method adopts a regional prevention and control mode, samples and surveys the pinworm in the area to be prevented and controlled, formulates a prevention and control mode according to the number of the pinworm in the area, compares the number of the pinworm in the area to be prevented and controlled and determines that the difference threshold value of the comparison number of the pinworm in the area to be prevented and controlled is 2.4 percent, and the value is the basis for judging whether the pinworm in the area to be prevented and controlled can continuously diffuse outwards, so as to judge whether the prevention and control area needs to be expanded according to the index. Meanwhile, in repeated counting, whether recounting is needed is determined according to the standard that the number of the eartip pinworm is increased by more than 30% compared with the previous counting. The purpose of accurate counting is achieved. The above modes are all proposed for the first time.
The invention aims at the pink borer in the great Khingan area, the pink borer in the area has stronger cold resistance, and the prevention and the treatment of larvae are more difficult.
