The invention relates to a method for preventing and controlling the American white moth by the golden wasp, which is characterized in that: the golden wasp is the cotton bollworm golden bee, and the control method comprises the following steps: (1) rearing the golden cotton bollworm adult; ( 2) Cultivate the yellow-pink beetle pupae, transfer the yellow-pink beetle larvae into an insect-raising box with ventilation holes, and then carry out a gradient cooling treatment, and place the treated yellow-pink beetle pupae in a 4°C incubator for protection from light to obtain a bee-receiving use. The yellow-pink beetle pupa; (3) receiving the bees, the step (2) the yellow-pink beetle pupa is reversely heated to receive the bee, and the ratio of the yellow-pink beetle pupa to the number of female adult bees of Helicoverpa armigera is 1:3; (4) parasitic Management of bee development; (5) release of parasitic wasps. The method adopts the alternative host yellow powder beetle pupae to breed Helicoverpa armigera on a large scale indoors, solves the problems of low success rate of the alternative host and the unstable number of breeding bees, and at the same time enriches the dominant parasitic wasp species in the control of American white moth, which is the most important in the United States. The biological control of white moth adds new means and new methods.

The invention discloses a fast-setting anti-corrosion cement using coal ash as a raw material and a preparation method thereof. The fast-setting anti-corrosion cement is prepared from the following components in parts by mass: 60-75 parts of coal ash, 25-40 parts of slaked lime, 0.5-1.5 parts of alkaline excitant, and 1-2 parts of sulfate excitant; the preparation method comprises the following steps: ball-milling the raw materials to obtain a batch mixture with 80-micron screen residue content less than 5%, adding 20-25 parts of water, uniformly stirring to prepare a raw material ball, hydro-thermally treating the raw material ball at 95-98 DEG.C for 10-16 hours to obtain a steamed material, calcining the steamed material at 750-900 DEG.C for 15-90 minutes, and cooling to obtain a synthetic material; and commonly ball-milling 75-85 parts of the synthetic material and 10-20 parts of Portland cement together with 5-8 parts of gypsum, 0.2-1.0 part of thickening time control agent and 0.3-0.7 part of water reducing agent until the 80-micron screen residue content is less than 4%. The cement is low in calcining temperature and thermal loss, high in coal ash utilization rate, fast-setting and fast-hardening, high in strength, and goon in sulfate attack resistance.
