(2) the indoor biological activity assay test of the present composition.
1, the indoor joint toxicity measuring of (R)-4-isopropenyl-1-methyl-1-cyclohexene and pyridine quinazoline to Bemisia tabaci, aphid
Test medicine uses (R)-4-isopropenyl-1-methyl-1-cyclohexene raw medicine and pyridine quinazoline raw medicine.
Referring to the spray-on process of the raw quasi- NY/T1154.9-2008 of mark, the target insect pest after choosing light anesthesia is placed in culture
In ware, spraying treatment, 4 repetitions of every concentration, 40 test worms of every repetition are carried out.It is disposed, is placed in the culture dish with foodstuff
Interior observation.Test worm death condition is checked after 72h, and is recorded, and test worm death judgment criteria is gently to contact test worm with writing brush
It is reactionless to be calculated as death.
It is for statistical analysis with DPS statistical analysis software, by the LC for calculating each medicament50It lives to evaluate the desinsection of each medicament
Property, and according to the co-toxicity coefficient (CTC value) of Sun Yunpei's Method calculating mixture.
Survey toxicity index (ATI)=(standard agent LC50/ reagent agent LC50)×100
Percentage composition+B the medicament toxicity index of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
The percentage composition of B in agent
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100
Act on the criteria for classifying according to NY/T1154.7-2006 insecticide combination: co-toxicity coefficient (CTC) >=120 shows as increasing
Effect effect；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 < co-toxicity coefficient (CTC) < 120 show as summation action.
As can be seen from Table 1 and Table 2, pyridine quinazoline and (R)-4-isopropenyl-1-methyl-1-cyclohexene combine in the range of 1~10:1~20 to tobacco powder
Lice, aphid co-toxicity coefficient (CTC) are all larger than 120, show synergistic function, still, (R)-4-isopropenyl-1-methyl-1-cyclohexene and pyridine quinazoline
Summation action is showed to Bemisia tabaci in 1:20, (R)-4-isopropenyl-1-methyl-1-cyclohexene and pyridine quinazoline are 20: summation action is showed to aphid.
The indoor joint toxicity measuring of 1 (R)-4-isopropenyl-1-methyl-1-cyclohexene of table and pyridine quinazoline to Bemisia tabaci.
The indoor joint toxicity measuring of 2 (R)-4-isopropenyl-1-methyl-1-cyclohexene of table and pyridine quinazoline to aphid.
3, aphid tests the drug resistance indoor measurement of (R)-4-isopropenyl-1-methyl-1-cyclohexene pyridine quinazoline.
Worm sources are acquired from Huizhou.The concentration that test medicine uses for the 50%-90% lethal dose of target insect pest,
It is configured to (R)-4-isopropenyl-1-methyl-1-cyclohexene, pyridine quinazoline raw medicine to test required test medicine.Test uses spray-on process, surveys with above-mentioned virulence
Fixed method is consistent.Dead test worm is rejected after 72 hours, is left test worm continuation living and is raised indoors, handles 20 repeatedly
For test worm.If the medical fluid processing containing only auxiliary agent is blank control.Each medicament is measured to 1st generation, the 5th generation, the 10th generation and the 20th generation
The half lethal concentration LC of test worm50, by comparing each treatment agent to the LC of 1st generation, the 5th generation, the 10th generation and the 20th generation test worm50
Change to evaluate test worm to the drug resistance of reagent agent, LC50It is smaller to show that drug resistance is lower.
According to table 7, table 8 and table 9 as can be seen that after (R)-4-isopropenyl-1-methyl-1-cyclohexene and pyridine quinazoline compound preparation 20 generation test worms of processing,
Target test worm population handles 20 generation test worms significantly lower than (R)-4-isopropenyl-1-methyl-1-cyclohexene and pyridine quinazoline single dose to the drug resistance of the compound preparation
The drug resistance of generation.This experiments have shown that, (R)-4-isopropenyl-1-methyl-1-cyclohexene and pyridine quinazoline compounding can effectively delay thrips, trialeurodes vaporariorum and aphid
Worm develops drug resistance.
3 (R)-4-isopropenyl-1-methyl-1-cyclohexene of table compounds the test of the measurement to aphid drug resistance with pyridine quinazoline.
In conclusion the present invention uses two kinds of active components for the complex composition of (R)-4-isopropenyl-1-methyl-1-cyclohexene and pyridine quinazoline, with
Existing single formulation is compared, and not only has apparent synergistic effect, also has good insecticidal effect, the lasting period is long, to agriculture
Crop safety can slow down the generation of pest resistance to insecticide, be worth promoting and applying in agricultural production.
