Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to an insecticidal composition for preventing and treating soybean aphids.
Background
The soybean aphid, commonly known as 'putrefaction', belongs to the family of homoptera aphids and is one of the main pests of soybean. Aphis fabae often gather on the back of tender stems and leaves of soybeans, suck juice, reduce the number of bearing branches and pods, reduce yield and transmit soybean mosaic virus diseases. At present, a single chemical prevention method is mostly adopted for preventing and treating soybean aphids in agricultural production, and the method has the defects of high cost, easy generation of drug resistance of the soybean aphids, killing of a large number of natural enemies of the soybean aphids such as ladybug and female bees and environmental pollution and ecological damage.
The paichongding is a novel pesticide developed by the cooperation of Jiangsu Kesheng group GmbH and Huadong university of science and technology. The paichongding belongs to a novel high-efficiency, broad-spectrum and low-toxicity nicotine pesticide, and the action mechanism is that the paichongding acts on an axon touch receptor of an insect nerve to block nerve conduction; acting on digestive tract system, the pests have obvious antifeedant effect after eating; acts on the mouth needle of the pests with piercing-sucking mouthparts to make the pests unable to take food. The paichongding is mainly used for preventing and controlling homopteran pests and has good prevention and control effect on soybean aphids and other pests. Although the paichongding has a new action mechanism, the long-term single use of the paichongding has the risk of resistance generation because the paichongding belongs to a new nicotine pesticide.
Cyantraniliprole is a second-generation ryanodine receptor inhibitor pesticide successfully developed by DuPont company after chlorantraniliprole, pests are controlled by activating ryanodine receptors of target pests, calcium ions stored in striated muscle and smooth muscle cells can be released by activating the ryanodine receptors, muscle contraction is prevented, so that the pests stop eating rapidly, muscle paralysis, vitality disappearance and paralysis occur, and finally the pests die.
At present, in pesticide research, active ingredients of different varieties are compounded, and the method is a common method for preventing and treating resistant insect pests. The compound formula with good synergy obviously improves the actual control effect and reduces the using amount of pesticide, thereby greatly delaying the generation of drug resistance and being an important means for comprehensively controlling insect pests. In the prior art, no compounding report of the paichongding and the cyantraniliprole is available.

The test method comprises the following steps: the toxicity effect of the tested pesticide on soybean aphids is determined by adopting a leaf soaking method. Using clear water as control, each drug was set to 5 concentrations, and each concentration was repeated 3 times. Removing winged aphids and small aphids on bean seedlings, only keeping wingless adult aphids and individual large wingless adult aphids, then soaking in prepared liquid medicines with different concentrations for 10s, wrapping bean seedling leaf stalks with absorbent cotton balls with good water absorbability, wrapping with preservative films, recording the number of aphids, treating, placing in a constant temperature oven for normal feeding, and checking the death rate after 24 h. During examination, the body of the insect is gently stirred by a writing brush, and if the insect is fallen down and cannot stand up, the insect is considered to die. The test conditions are that the temperature is 25 +/-1 ℃, the relative humidity is about 75 percent, the light cycle L: d ═ 16: 8. the virulence regression equation and EC50 were calculated using SPSS13.0 biometric software. And finally, calculating the co-toxicity coefficient (CTC) according to the Sun Yunpei method.
When the CTC is less than or equal to 80, the composition shows antagonism, when the CTC is more than 80 and less than 120, the composition shows additive action, and when the CTC is more than or equal to 120, the composition shows synergistic action.
Measured virulence index (ATI) ═ standard agent EC 50/test agent EC50 x 100
