Problems solved by technology

However, the existing biological trapping balls are all made of ordinary plastic balls or resin balls, which are not only difficult to degrade, but also very unfriendly to the environment. It needs a large amount of attractant to lure to achieve the trapping effect

Embodiment 1

[0023] When preparing the fruit fly trap ball, first mix 200g of talc powder into a sufficient amount of ethanol solution and stir evenly, then add 10kg of polylactic acid particles and mix evenly again, control the drying temperature at 65~68°C, and dry the above mixture After removing the organic solution, low-degree crystallization is carried out to obtain polylactic acid crystals. Separating the polylactic acid crystals with L / D=90 basic magnesium sulfate whiskers, M-51 MBS, plastic heat stabilizer, talc powder passing through a 3000 mesh sieve and bright cadmium green dyeing agent according to the mass ratio of 1:0.03 Add the ratio of :0.05:0.03:0.03:0.03 into the drum, and use the drum to mix the mixture evenly.

[0024] Then introduce the above-mentioned uniformly mixed mixture into the booby ball model, control the injection molding temperature at 160~180°C, and carry out injection molding at the mold temperature of 80~90°C to make several booby ball models with a sing...

Embodiment 2

[0026] When preparing the fruit fly trapping ball, first mix 400g of talc powder into a sufficient amount of ethanol solution and stir evenly, then add 20kg of polylactic acid particles and mix evenly again, control the drying temperature at 66~68°C, and dry the above mixture After removing the organic solution, low-degree crystallization is carried out to obtain polylactic acid crystals. Separating the polylactic acid crystals with L / D=90 basic magnesium sulfate whiskers, M-51 MBS, plastic heat stabilizer, talc powder passing through a 3000 mesh sieve and bright cadmium green dyeing agent according to the mass ratio of 1:0.03 Add the ratio of :0.05:0.03:0.03:0.03 into the drum, and use the drum to mix the mixture evenly.

[0027] Then introduce the above-mentioned uniformly mixed mixture into the booby ball model, control the injection molding temperature at 200~210°C, and carry out injection molding at the mold temperature of 90~100°C to make several booby ball models with a...

Abstract

The invention discloses a preparation method of a fruit fly baiting and killing ball. The preparation method comprises the following steps: firstly, mixing talcum powder with an ethanol solution and preparing polylactic acid crystals together with polylactic acid particles; then adding basic magnesium sulfate whiskers, MBS, a plastic heat stabilizer, talcum powder and a staining agent into the polylactic acid crystals to prepare mixture powder; injection-molding the mixture powder to obtain a baiting and killing ball model; gluing a surface after punching the baiting and killing ball model andadding a lure; and wrapping the surface of a glue layer with release paper to obtain a finished product of the fruit fly baiting and killing ball. The fruit fly baiting and killing ball prepared in the invention is high in killing efficiency, stable in prevention effect, friendly to the environment and naturally degradable in the environment.

Description

technical field [0001] The invention relates to the technical field of fruit tree pest control, in particular to a method for preparing a fruit fly trapping ball. Background technique [0002] Bacteralis citrus, commonly known as "citrus maggot", belongs to Diptera Tephritidae, is a destructive pest to citrus crops, and is a plant quarantine pest at home and abroad. Bactrocera citrus overwinters in the soil as a pupae, emerges in mid-May, and flies into the miscellaneous woods near the citrus orchard to feed and supplement nutrients. After adult sexual maturity, it flies to citrus fruits to mate and lay eggs. The critical period of control is the adult period. Since Bactrocera citrus does damage through larvae mothing in citrus fruits, the control effect of spraying pesticides is not good, and the commonly used control method is to trap and kill its adults with attractants. These include protein attractants, sex attractants, food attractants, etc. [0003] Among them, the...
