Control beet armyworm, diamondback moth, Pieris rapae, Prodenia litura, lopper worm, bollworm, oriental tobacco budworm, volume
The application of one or more in leaf moth class, carpocapsa pononella, leafhopper, diamond and colorado potato bug.
The present inventor it has been investigated that, the insecticides of the present invention can expand indoxacarb, lufenuron list
The insecticidal spectrum of one composition, it is possible to improve indoxacarb, lufenuron to a greater degree to beet armyworm, diamondback moth
Deng prevention effect, using dosage can be reduced simultaneously, reduce the pollution to environment.Further, the present invention carries
The insecticides of confession, the proportioning of two kinds of active component has obvious potentiation, to insect pest of the plant
Prevention effect is notable, and the particularly preventing and treating to beet armyworm, lopper worm, bollworm and/or Pieris rapae is imitated
Fruit is notable.
Additionally, the insecticides of the present invention can have the change of weeding, parasite killing or bactericidal property with other
Compound, particularly tags and stomach toxicity type insecticide is used in mixed way, it is possible to nematicide, protective agent, life
Long regulator, nutrient for plants or soil conditioner etc. are used in mixed way.
Specifically, the having the beneficial effect that of insecticides of the present invention:
1), in the insecticides of the present invention, each active component is compounding in certain ratio range, performance
Going out fabulous potentiation, mixed compositions relatively its single dose significantly improves insecticidal effect, and then fall
Low using dosage, while reducing peasant's drug cost, decreases the degree of effect on environment；
2) insecticidal spectrum is expanded so that a kind of medicament can prevent and treat multiple insects simultaneously, it is provided that one is extremely

Hereinafter by embodiment, the present invention will be conducted further description, but the present invention will be not limited in down
State embodiment.
In following embodiment, indoxacarb is purchased from Shangyu Nutrichem Co., Ltd, registration card number:
PD20122031, lufenuron is purchased from Shangyu Nutrichem Co., Ltd, registration card number:
PD20151795。
Test example 1
The purpose of this test example is to study the potentiation that indoxacarb is mixed with lufenuron.
(1) worm kind is measured
Diamondback moth (Plutella xylostella) is raised in indoor Vermiculitum Turnip Sprouts method.
(2) assay method
Assay method uses blade infusion process.By the cabbage leaves without pollution by pesticides with after dish detergent wash clean
Dry.After indoxacarb and the former medicinal acetone of lufenuron are made into mother solution, with the Triton X-100 of 0.01%
It is diluted to required concentration, is made into the mixture of different ratio simultaneously on demand.Ready blade is soaked
In medicinal liquid 10 seconds, after taking-up, vertically it is hung on iron wire and dries in the shade.The blade dried in the shade is placed on cultivation
In ware, access three age primary larva.Keep 25 DEG C, check mortality rate at 24 and 48 hours respectively.
Each medicament or be diluted to 5-7 concentration by proportioning (weight ratio), each concentration 3-5 repeats,
Each repetition 15-20 head diamondback moth larvae.
(3) statistical analysis
With Polo software, the data obtained carried out machine value analysis, the invalid mensuration of automatic rejection.According to Sun
The program calculating co-toxicity coefficient (CTC), co-toxicity coefficient=actual measurement is write etc. method Excel 9.0 platform
Toxicity index/theory toxicity index × 100, the LC calculated according to Polo50Or LC90CTC is calculated with proportioning
Value.When CTC >=120, show as potentiation；When CTC≤80, show as antagonism；80 ＜ CTC
＜ 120, shows as summation action.
(4) result and discussion
Indoxacarb is quickly converted to DCJW (N-removes methoxycarbonyl group metabolite) in insect bodies, by
DCJW acts on insecticide neurocyte inactivation state Voltage-gated sodium channels, acts on elder brother with lufenuron
Worm larva, stoping exfoliating process and the difference that kills off the insect pests, the two is mixed in certain proportion has significantly
Potentiation, the results are shown in Table 1 with table 2 (table 1 is indoxacarb toxicity test result mixed with lufenuron,
Table 2 is indoxacarb toxicity test co-toxicity coefficient mixed with lufenuron (CTC) statistical table (LC50))。
