The method has the advantages of simple process and convenient operation. With the bio-pesticide, occurrence and harm of C. medinalis can be effectively controlled. The bio-pesticide can be applied with large amount on paddy rice, especially on pollution-free rice and organic rice.

The invention belongs to the technical field of biological Helicoverpa armigera prevention and control, and particularly relates to a method for improving the biological Helicoverpa armigera prevention and control effect of nuclear polyhedrosis viruses (NPVs). The method can improve the Helicoverpa armigera prevention and control effect of NPVs through the feeding of a Helicoverpa armigera C-type lectin dsRNA (double-stranded ribonucleic acid) (Ha-lectin1 dsRNA); the Helicoverpa armigera prevention and control effect of NPVs can be remarkably improved at a dosage of 3 micrograms of Ha-lectin1 dsRNA and 50 PIBs (polyhedral inclusion bodies) of NPVs per larva of Helicoverpa armigera. The method provided by the invention has a fast onset of insect killing, that is, the time of Helicoverpa armigera death caused by Helicoverpa armigera NPVs (HaNPVs) can be shortened by 1 / 3; the insect killing efficiency is high, that is, the killing rate in the first three days can be increased by 35 percent; the consumption is low, that is, the use consumption of NPVs can be greatly reduced. Compared with the method which simply uses NPVs for Helicoverpa armigera prevention and control in the prior art, the method provided by the invention achieves remarkable improvements.

The invention discloses a preparation method of dried salted duck, which is characterized in that: a duck is electrically shocked and killed and then is completely depilated through a complete depilation process combining an ironing process and a secondary ironing process, chest of the duck is cleared, the duck with feet, wings and head being removed is salted, then the duck is immersed in saltwater brine, and finally the dried salted duck product is obtained through a dehydration process combining the baking dehydration and the natural air drying. The preparation process of the dried salted duck is free from being influenced by the weather, the duck is thoroughly depilated, and at the same time the prepared dried salted duck has strong cured flavor and good taste.

The invention discloses a control agent composition for winged pests of fruits and vegetables grown in greenhouses, a sticky insect board and a control method. In parts by weight, the control agent composition comprises 8-12 parts of enidine, 5-10 parts of pymetrozine, 7-25 parts of picrolactone, 20-30 parts of azadirachtin and 10-15 parts of Zinnia extract; the sticky insect board includes a yellow sticky insect board, the above-mentioned composition coated on the yellow sticky insect board, 35-48 parts of slow-release synergist, adhesive and zeolite powder; the addition of said adhesive and the ratio of the composition are 3-4:1; said slow-release synergist and said The dosage ratio of the composition is 5-7:1; the present invention not only has remarkable effect, but also avoids pesticide residues in food, and is green and safe by formulating an effective insect-repelling agent and then cooperating with the sticky insect board.

The invention discloses a recombinant fungus targeted at silencing the expression of the pest pattern recognition protein GNBP3 gene and its application in pest control. The invention constructs a recombinant Beauveria bassiana that can inhibit or block the transcription of the GNBP3 gene. As a result, when the recombinant Beauveria bassiana infects pests, the expression of antimicrobial peptides in the pests is significantly down-regulated, weakening or interrupting the signal transduction of pests to recognize and immune fungi, and making pests more susceptible to infection and death by pathogenic microorganisms such as fungi. Recombinant Beauveria bassiana significantly increased the mortality of pests and shortened the death time in a concentration-dependent manner. Combining it with microbial-derived insecticides Bacillus thuringiensis Bt or Serratia marcescens can significantly increase the mortality and death time of recombinant Beauveria bassiana against pests, indicating that it is a good microbial insecticide. The synergist, not to mention improving the killing effect, broadens the insecticidal spectrum, reduces the resistance of microbial insecticides, and is an environmentally friendly microbial source insecticide.

The invention discloses a self-defined method for constructing a connected dominating set based on an exclusive region in a wireless sensor network. According to characteristics of a virtual backbone network of the wireless sensor network and a construction algorithm of a distributed connected dominating set, the method provided by the invention introduces concepts of exclusive coverage and a delay waiting rule, and through the combined action of both concepts, each node maintains at most one node in own exclusive region, so that the scale of the connected dominating set is reduced, and the distribution of dominating nodes is more uniform. The method can reduce the scale of the connected dominating set well, ensure the distribution of the dominating nodes to be uniform and sparse, save energy, prolong the life cycle of a whole network, and well adapt to the wireless sensor network with dense node distribution.
