Preferably, the release density of the orius pollidii is 9m per time2Releasing 10 heads, wherein the releasing insect state is that the ratio of adult male to adult female is 1: 1, hanging the small release cage filled with the orius mirificus at a position close to the tip of the tobacco in the transplanting field during release.
Preferably, the biopesticide is rotenone or spirotetramat; the rotenone is 6 percent microemulsion, and the spirotetramat is 22.4 percent suspending agent.
By adopting the technical scheme, the damage of tobacco thrips to tobacco can be effectively prevented and treated, and the economic loss caused by the damage of thrips to tobacco is reduced.
Detailed Description
It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
In the first embodiment, the method for preventing and controlling tobacco thrips by combining physical and biological modes and peak staggering comprises the steps of hanging a pest sticking plate with a blue background when the height of the transplanted tobacco seedlings is lower than 20cm after the transplanted tobacco seedlings are transplanted, wherein the density of the pest sticking plate in a tobacco transplanting field is 9 m/9 m2Spraying a biological pesticide when the height of the transplanted tobacco seedlings is 50-60cm, wherein the pesticide is rotenone or spirotetramat; the rotenone is 6 percent microemulsion, and the spirotetramat is 22.4 percent suspending agent. The first time of releasing the orius pollidii is carried out 6-9 days after the biological pesticide is sprayed, the second time of releasing is 10 days after the first time of releasing, and the third time of releasing is 20 days after the first time of releasing.
Further, the size of the mythimna separata plate is 25 x 30 cm.
Further, the release density of the orius pollidii is 9m per unit2Releasing 10 heads, wherein the releasing insect state is that the ratio of adult male to adult female is 1: 1, hanging the small release cage filled with the orius mirificus at a position close to the tip of the tobacco in the transplanting field during release.
In the second embodiment, the first embodiment of the method,
experimental insects:
in tested insects, natural enemies selected orius miniatus moving on outdoor tobacco, bred with thrips indoors for 2-3 generations, and selected male and female adults emerging on the same day for later use. The test thrips is carried out by selecting the western thrips and the tobacco thrips which are widely distributed and seriously harmful on the tobacco, and the two thrips can often coexist on the tobacco simultaneously for harm. The Frankliniella occidentalis and Frankliniella tabaci are collected outdoors and separately raised indoors for 2-3 generations by matching with tobacco seedlings and kidney beans.
Experimental plot setup
Selecting 3 samples (area about 1000 m) in tobacco planting area2) And (3) carrying out a comparative test, dividing each sample land into 3 test areas, planting 3 rows of corns among each cell as a protection row, wherein each cell respectively adopts blue armyworm plate control, biological insecticide control and southern orius miri control and peak staggering control as described in the embodiment one. The investigation was performed every 30 days after the transplantation of the tobacco seedlings. The total number of surveys was 5 (the results are shown in table one). And (3) changing the plate, spraying the biological insecticide and releasing the orius miniatus one day after each investigation, wherein the orius miniatus still has higher population density due to the staggered peak control method in the fifth control, and does not need to be released for use.
Preventing and treating effect of different preventing and treating modes on thrips
It can be seen from the table one that, after different control methods are adopted for control, the peak staggering control has better control effect because the control is combined with the occurrence dynamics of insects, the population density of the thrips is lower after each control, in other control methods, the control of the blue plate is poorer, the biological insecticide can cause the re-outbreak of the thrips population because a certain time interval is needed, and the control by adopting the orius miri has relatively better control effect because the continuous control of the orius miri has better control effect if the control effect is combined control.
Control cost of different control modes of watch two
The second table can obtain the control cost of different control methods, under the same time and normal use condition, the control cost of the orius similis is greater than that of the blue plate control, the peak staggering control and the biological insecticide control, and although the control cost of the peak staggering control is not the lowest, the cost can be saved compared with other control methods.
The two test results are combined, the prevention and control method has the advantages of good effect and low prevention and control cost on the thrips on the tobacco, can effectively combine the growth period of the tobacco and the dynamics of thrips population for prevention and control when being used in the field in practice, can timely adjust physical and biological prevention and control methods, does not use chemical pesticides, and reduces the harm of the chemical pesticides to the environment. Has beneficial effect on the field production.
According to the invention, most of thrips can be effectively killed by spraying the biopesticide after the sticky plates are hung, but pest thrips can also be bred in the later period after killing, the tobacco thrips can be effectively prevented and controlled by hanging the sticky plates with blue background and combining with orius miniatus, and the economic loss caused by damaging tobacco by the thrips is reduced. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
