Embodiment Construction

[0018] The present invention further illustrates the present invention with following examples, but protection scope of the present invention is not limited to following examples.

[0019] 1. Behavioral responses of beet armyworm to isofennel, α-terpinene and gerbilene B complex

[0020] A Y-type olfactometer was used to measure the behavioral response of the beet armyworm to the compound (improved by our laboratory based on the basic principle of the olfactometer, the authorized patent number is ZL201020239767.7). The main arm of the Y-shaped tube is 20cm, the length of the two arms is 10cm, and the angle between the two arms is 90°C. At the ends of the tubes of the two arms, silicone tubes were used to connect the distilled water bottle and the activated carbon bottle in sequence. Finally, the activated carbon bottle was opened in the atmosphere, and the insect release bottle was connected to the suction device with gauze. Cut the filter paper strip into 5cm×1cm, fold it in...

Abstract

The invention discloses a lepidoptera insect insecticide synergist. Active ingredients of the lepidoptera insect insecticide synergist include iso-ascaridole, alpha-terpinene and germacrene B, a mass concentration ratio of the iso-ascaridole to the alpha-terpinene to the germacrene B in a solvent is 1-20:1-10:1-15, and the active ingredients can be extracted from dysphania ambrosioides or chenopodium aristatum. When the insecticide synergist is used for killing lepidoptera insects, a volume percentage concentration of the iso-ascaridol, the alpha-terpinene and the germacrene B in an insecticide is 1-15%. According to pharmacodynamic tests, insecticide efficacies can be remarkably improved by consumption of a small quantity of the lepidoptera insect insecticide synergist, and insecticide consumption can be reduced by 20-45% under equal control effects, so that insecticide consumption is effectively reduced, drug resistance of harmful organisms is overcome and weakened, environment pollution is reduced, and remarkable economic benefit and environment protection significances are achieved.

Description

technical field [0001] The invention belongs to the technical field of pesticide synergists, in particular to a synergist for lepidopteran insecticides. Background technique [0002] At present, pesticides are still the main method of controlling pest damage in agriculture. However, due to the irrational use of pesticides, 3R (resistance, pesticide residues, and rampant) problems have been caused. For example, diamondback moth has developed resistance to more than 50 insecticides, even benzoylthioureas, insect growth regulators, spinosads, and Bt, which were previously considered difficult to develop resistance, have also developed resistance. . The emergence of insecticide resistance has increased the difficulty of pest control, and the common response method is to increase the amount of pesticides in the field. However, the extensive use of pesticides is the key source of a series of problems such as human and animal poisoning and pesticide residues, and it also makes ma...
