Attractant for juxiaoshi fly

The invention provides a bactrocera dorsalis amphoteric attractant as well as a preparation method and an application thereof. The bactrocera dorsalis amphoteric attractant comprises hesperetin, alcohols, ketones, methyleugenol, esters, vegetable oil, an antioxidant, added auxiliary components such as an antioxidant, an anti-ultraviolet agent and an anti-bactericide agent as well as a thickening agent, a slow-release agent and the like and is put in a deep color container with a cover so as to be preserved. The main components and the raw materials of the amphoteric attractant derive from natural plant extractives, so that the amphoteric attractant is environmentally-friendly and is safe for non-target organisms; the bactrocera dorsalis amphoteric attractant has a very good trapping effect on female adults and male adults of bactrocera dorsalis in combination with the integrated application of other solid sustained-release materials and is capable of effectively reducing the population cardinal number of the bactrocera dorsalis in a using region generation by generation. The bactrocera dorsalis amphoteric attractant is simple in synthesis process, low in cost and suitable for wide application and popularization in orange producing areas and other bactrocera dorsalis host crop producing areas and is also effective for injurious insects such as bactrocera zonata and melon flies.

Bactrocera dorsalis amphoteric attractant as well as preparation method and application thereof

The invention discloses a bactrocera dorsalis slow-release type attractant which includes the following components by mass percent: 80-90% of methyl eugenol, 5-10% of a synergist and 5-15% of a slow-release agent, wherein the synergist adopts one or more of orange oil, psidium guajava essential oil, mango essential oil, loquat flower essential oil and carambola essential oil; the slow-release agent adopts one or more of vegetable oil and gutter oil. The bactrocera dorsalis slow-release type attractant provided by the invention adopts a simple, effective and pollution-free slow-release and synergistic technology, and includes not only methyl eugenol active substances but also plant essential oil which has a synergistic effect, as well as the slow-release drug for increasing the drug effect duration, so as to prolong the attraction time and improve the attraction effect of the bactrocera dorsalis attractant, and satisfy technology requirements for effective and long-lasting prevention and control. The raw materials used by the bactrocera dorsalis slow-release type attractant have the characteristics of being environment-friendly, low in cost and long in drug effect duration.

Synergistic agent for killing Formica rufa

The invention discloses a fumigation composition and an application thereof to the prevention and control of pests of volvaria volvacea. The fumigation composition for preventing and controlling the pests of the volvaria volvacea comprises the components in parts by volume: 1-2 parts of myrcene and 1 part of alpha-pinene; and the fumigation composition has prominent fumigation activity for the pests of the volvaria volvacea in an enclosed environment and is capable of preventing and relieving damage of the pests to mycelia of the volvaria volvacea. The fumigation composition disclosed by the invention belongs to a botanical insecticide and is easy to decompose, incapable of polluting the environment and safe to people and livestock; and the fumigation composition loses activity after deinsectization and cannot be accumulated in bodies of the pests or foods, so that the ecological environment and food safety are protected; and the fumigation composition is simple and feasible in preparation method, wide in raw material source, low in cost and suitable for large-scale production so as to be widely used for preventing and controlling the pests of the volvaria volvacea.

Fumigation composition and application thereof to prevention and control of pests of volvaria volvacea

The invention discloses a combined synergistic agent for carbamide pesticides and an environment-friendly pesticide containing the same. The combined synergistic agent comprises salicylic acid and triphenyl phosphate; the laboratory test and the field test show that two types of carbamide pesticides have obvious synergistic effect through combining salicylic acid and triphenyl phosphate and then compounding with triflurnuron or hexaflumuron, so that the time of killing pests by triflurnuron can be shorted, the insecticidal activity of hexaflumuron is improved, pests can be prevented from damaging crops, and the usage amount of the pesticide can be reduced while the equivalent prevention effect is achieved; the synergistic effect of the combination of salicylic acid and triphenyl phosphateused as a synergistic agent on triflurnuron or hexaflumuron is remarkably better that of salicylic acid which is used as a synergistic agent individually and that of salicylic acid which is used as asynergistic agent individually, and the salicylic acid and triphenyl phosphate have a synergism effect.
