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.

Improved food attractant for citrus fruit fly

The invention discloses a method for producing spinosad stored-grain protectant using nano-titania and corn starch as auxiliaries The stored-grain protectant comprises spinosad, nano-titania and corn starch and is in a powder type The stored-grain protectant is used for controlling stored-grain insects The technical scheme is characterized in that the spinosad, the nano-titania and the corn starch are mixed and pneumatically smashed into powder, and the protectant is mixed to the surface of grains during grain packaging or metered and sprayed above a large-sized conveying belt during grain storage The process of the stored-grain protectant for stored-grain protection is simple and feasible, materials of the stored-grain protectant are easy to obtain, the stored-grain protectant is safe, environment-friendly and effective, and the problem of stored-grain safety is solved for large-sized storage depots and small farmers

Formula and preparation method of stored-grain protectant

The invention discloses a citrus fruit fly attractant and a preparation method thereof, and belongs to the field of preventing plant diseases and insect pests. The attractant comprises the following components in parts by weight: 150-400 parts of eugenol methyl ether, 3-5 parts of ethyl butyrate, 10-12 parts of geraniol, and 6-10 parts of linalool, and further comprises 2-8 parts of 2,6-butylated hydroxytoluene. The preparation technology comprises the following steps: weighing and taking the eugenol methyl ether, the ethyl butyrate, the geraniol and the linalool in parts by weight, pouring the eugenol methyl ether, the ethyl butyrate, the geraniol and the linalool which are weighed and taken into a beaker, adding water into the beaker, and fully stirring the mixture of the eugenol methyl ether, the ethyl butyrate, the geraniol, the linalool and the water so as to obtain a fragrance source agent of which the concentration is 10 g/mL-10 g/mL; weighing and taking the 2,6-butylated hydroxytoluene in parts by weight, pouring the weighed and taken 2,6-butylated hydroxytoluene into the beaker, adding the water into the beaker, and fully stirring the mixture of the 2,6-butylated hydroxytoluene and the water so as to obtain an oxidizing agent solution of which the concentration is 10 g/mL-10 g/mL; respectively putting the obtained fragrance source agent and the obtained oxidizing agent solution into a freezing chamber to perform the preservation, wherein the refrigerating temperature is 4-8 DEG C; during use, uniformly mixing the fragrance source agent and the oxidizing agent solution according to the compounding ratio of 10:1 so as to obtain the citrus fruit fly attractant of which the concentration is 10 g/mL-10 g/mL. According to the method, not only the production is simple, but also the cost is low, and products have the characteristic that the attractive effect is strong.

Citrus fruit fly attractant and preparation method thereof

The invention relates to an attractants for Bactrocera dorsalis, which comprises constituents of (by mass portions) methyleugenol 5000-50 parts, butyl acetate 1 part. The attractant can trap Bactrocera dorsalis effectively.

Oriental fruit fly attractant

An intensified insecticide for red ant is proportionally composed of the mixture of fipronil, abamectin, hydramethylnon, pyripropanol, etc, the cracker powder, the nanoparticles of one or more of SiO2, diatomite, tricalcium phosphate, zeolite, TiO2, alumina, etc, and potassium sorbate

Synergistic agent for killing Formica rufa

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.
