Description
Technical field
The invention belongs to field of agricultural production technologies, more particularly, to a kind of Nicotiana tabacum L. oriental tobacco budworm Pesticidal combination, further relate to one
Plant the preparation method of above-mentioned Nicotiana tabacum L. oriental tobacco budworm Pesticidal combination.
Background technology
Oriental tobacco budworm popular name Kattapillar, also known as cigarette beetle, annual there is 2-6 generation, change with the temperature conditionss of different cigarette districts and
Change.In the Yellow River and Huai He River cigarette district, pupa is survived the winter in 7-13 centimetre of deep soil, and winter generation adult late May to early June occurs, and
For spawning period；2-4 for spawning period respectively on June early and middle ten dayses to July, the middle ten days, on early July to August, the middle ten days, in August
Ten days is to early September.The first generation is to third generation main harm spring, summer cigarette；Forth generation then main harm summer fireworks piece, fruit, wherein
The heaviest with second, third generation harm Nicotiana tabacum L..Oriental tobacco budworm does not just have wing can jump by the larva that ovum is hatched, form and life habit
Similar to adult, simply the insecticide of the less this form of body makes nymph gradually grow up again, when can not by ectoskeletal restriction
When growing up again, just take off original outer skeleton, this cries casts off a skin；Nymph all one's life will cast off a skin 5 times；Casted off a skin by egg hatching to first time,
It was 1 age, often casts off a skin once later, increase by 1 age；After abdominal part circle, wing bud is notable；After, become adult.Body colour changes greatly,
There are green, taupe, green and brown color etc. multiple.The green and brown color of mature larva, is about 40 millimeters, body surface is more smooth, and the body back of the body has white point
Line, each section has strumae, upper raw black undercoat.
In view of the serious harm of Nicotiana tabacum L. oriental tobacco budworm, countries in the world all strengthen to Nicotiana tabacum L. oriental tobacco budworm biology, Population Ecological
Learn the research work with aspects such as integrated controls, to new insect protected or disinsection method can be developed.In recent years, due to parasite killing
A large amount of uses of agent, not only pollute environment, and the residual of pesticide is also unfavorable for that people's is healthy.
Content of the invention
An object of the present invention is to provide a kind of preparation method of Nicotiana tabacum L. oriental tobacco budworm Pesticidal combination, its preparation method letter
