Description
Technical field
The present invention relates to technical field of pesticide combination, particularly relate to the Insecticiding-miticiding mixture that contains spiral shell mite ester and Acetamiprid.
Background technology
Spiral shell mite ester (spirodiclofen), chemical name: 3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro [4, the 5]-last of the ten Heavenly stems-3-alkene 4-base-2,2-dimethyl butyrate acid esters.Can be used to prevent and treat the pest mite class existing miticide being produced to resistance.Show after deliberation, the energy metabolism of this medicament by suppressing the Fatty synthesis in pest mite body to block mite.The mite that kills of spiral shell mite ester composes wide, strong adaptability, and the mite evil that can be used for the solanaceous crops such as the fruit tree such as citrus, grape and eggplant, capsicum, tomato is administered.Without cross resistance between spiral shell mite ester and existing miticide, mixedly now can to use with most of agricultural chemicals (strong basicity agricultural chemicals and copper agent except) is existing.In addition, spiral shell mite ester has insects such as pear sucker, oystershell scale and leafhopper classes and well doublely controls effect.
Acetamiprid (acetamiprid), chemical name: N-(N-cyano group-ethyleneimine base)-N-methyl-2-chloropyridine-5-methylamine, for chloro nicotinic insecticide, all effective to Semiptera (aphid, leafhopper, aleyrodid, coccid, scale insect etc.), Lepidoptera (diamond-back moth, lyonetid, Grapholita spp, leaf-roller), coleoptera (longicorn, daikon leaf beetle) and total wing order insect (thrips class).Show after deliberation, this pharmacy effect is in the nAChR of insect nerve system synapses, and the neural stimulation of interference insect is conducted, cause nervous system path blockade, cause neurotransmitter acetylcholine in the accumulation of synapses, thus cause insect paralysis, finally dead.In addition, this medicament has that insecticidal spectrum is wide, activity is high, consumption is few, the long feature such as quick-acting again of holding effect, and has the systemic activity of brilliance.Because Acetamiprid mechanism of action is unique, to organic phosphor, carbamate, and the insect that the pesticide species such as pyrethroid develops immunity to drugs has better effects.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of compound insecticidal containing spiral shell mite ester and Acetamiprid and kills mite mixture; Sucking pest and the plant evil mites such as this mixture can be used for anti-eliminating aphis, aleyrodid, can be used for preventing and treating pesticide resistance sucking pest especially.
In order to solve the problems of the technologies described above, the invention provides a kind of compound insecticidal containing Acetamiprid and kill mite mixture, this compound insecticidal kills mite mixture and is grouped into by the one-tenth of following weight content: spiral shell mite ester (as composition A) 10% ~ 90% and Acetamiprid (as composition B) 90% ~ 10%.

Embodiment
Embodiment 1, indoor single dose toxicity test:
Adopt blade infusion process.Win fresh pumpkin blade, be cut into cutting ring the disk that diameter is about 3cm, be placed on taking-up after soaking 5s in ready liquid and at room temperature dry, be laid in the 3cm culture dish loading 1% agar (3cm is thick) in advance, every ware puts 1.Test establish the chemicals treatment of 6 concentration (that is, the concentration of Acetamiprid, spiral shell mite ester be respectively 5,10,20,40,80,160mg/L), each process 3 repetition; Separately soak blade with clear water and to be laid in culture dish in contrast after drying.Use pest sucking device to draw Bemisia tabaci adults of the same size (Bemisia tabaci belongs to sucking pest) from cultivation cage and freeze 40-60s in refrigerator and cooled, after removing male worm, female worm is positioned in culture dish, female worm 30 ~ 40 placed by every ware, covers culture dish lid.Illumination box culture dish being placed in 25 ± 2 DEG C of 70%RH is cultivated, and arranges the Dark-light cycle of 12/12.After 72h, check Bemisia tabaci adults death condition (touch Bemisia tabaci adults gently with fine, soft fur pen, the motionless person of health is dead).Then calculate lethality, if control group lethality is higher than 20%, then tests calcellation and reform.Lethality Abbott formula correction, then according to log concentration---lethality probit value analyzes (Bliss) method, obtains virulence regression equation and lethal concentration of 50 LC
50value.

Embodiment 2, formula indoor screen:
According to the toxicity test result of single dose, according to spiral shell mite ester (A): Acetamiprid (B) is respectively the ratio of 3:1,2:1,1:1,1:2,1:3.Adopt said method to carry out toxicity test, calculate LC
50, and press abundant method calculating co-toxicity coefficient (CTC) of Sun Yun, obtain best composite reagent formula.Co-toxicity coefficient (CTC) computing formula is as follows: (with spiral shell mite ester for standard agent, its toxicity index is 100):
LC50 × 100 of the LC50/B of toxicity index (the TI)=A of Acetamiprid
LC50 × 100 of the LC50/M of actual toxicity index (the ATI)=A of M
TI × the P of theoretical toxicity index (the TTI)=A of M
atI × the P of+B
b
TTI × 100 of the ATI/M of co-toxicity coefficient (the CTC)=M of M
In formula:
M is the mixture of A and B by different ratio
P
bfor the ratio that B is shared in mixture
P
afor the ratio that A is shared in mixture
Note: CTC>100 is synergy; CTC is 80 ~ 100 is addition; CTC<80 is antagonism.
