Description
Technical field
The invention belongs to field of agricultural production technologies, more particularly to a kind of diamondback moth Pesticidal combination, further relate in one kind
State the preparation method of diamondback moth Pesticidal combination.
Background technology
Diamondback moth, belongs to lepidoptera diamond-back moth section, another name：Little green grass or young crops worm, pointed at both ends, the worldwide insect that migrates, main harm cross
Flower section plant.Diamondback moth mainly endangers blade with larva, and younger ones in an age group's Larva is little, only gnaws mesophyll, and little hollow hole is caused on blade face, has
When head can cause harm in potential leaf texture；How mesophyll is taken food in leaf back after larva is slightly larger and leave a face epidermis, become transparent plaque-like
Such as " scuttle ", blade can be eaten into hole after 3～4 ages or incise, serious dish leaf is reticulated.Diamondback moth can also endanger
Reserve seed for planting the tender stem children pod and seed of dish, directly affect yield.
Diamondback moth all parts of the country generally occur, 1 year 4～19 generation of life.There are for 4～5 generations in the north, the Yangtze river basin 9～
14 generations, 17 generation of south China, 18～19 generation of Taiwan.Survived the winter in stubble fallen leaves, weeds clump with pupa in the north；Visible all the year round each in south
Worm state, phenomenon of no surviving the winter.In annual, northeast, North China are with 5～June and 8～September because different from different places the harm Sheng phase
Harm is serious, and spring overweights autumn.In Xinjiang, then the harm of 7～August is most heavy.South with 3～June and 8～November be occur
Sheng Qi, and autumn overweight spring.Adult is hidden by day and come out at night, and is hidden in plant clump daytime more, and post sunset comes into play.There is light
Property, it is the peak period for flutterring lamp during with 19～23.
In view of serious harm of the diamondback moth to vegetables, countries in the world are all strengthened to diamondback moth biology, genecology
With the research work of the aspects such as integrated control, to new insect prevention or disinsection method can be developed.In recent years, due to insecticide
A large amount of uses, not only pollute environment, the edible crop that sprays insecticide also is 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 diamondback moth Pesticidal combination, and which is prepared simply, and institute
Obtained Pesticidal combination environmental protection, there is good insecticidal effect to diamondback moth.
In order to solve above-mentioned technical problem, the present invention is employed the following technical solutions：A kind of system of diamondback moth Pesticidal combination
