This invention belongs to the field of biopesticide technology, specifically to a biopesticide for controlling the new pineapple mealybug. The application of *Bacillus tuvani* in the preparation of a biopesticide for controlling the new pineapple mealybug is described. The *Bacillus tuvani* was purchased from the Guangdong Provincial Microbial Culture Collection Center, number GDMCC NO.800089. The *Bacillus tuvani* bacterial solution of this invention exhibits insecticidal activity against the new pineapple mealybug, demonstrating the potential for preparing a biopesticide for its control. Furthermore, when the *Bacillus tuvani* bacterial solution is used in combination with the existing biopesticide spinosad, it has a synergistic effect in killing the new pineapple mealybug, further improving the control effect and providing support for the preparation of a biopesticide for controlling the new pineapple mealybug.

The invention discloses a papaya Pleurotus geesteranus trehalose synthase gene PmTPS as well as an encoding protein, dsRNA and application thereof, belongs to the technical field of molecular biology, and particularly relates to the papaya Pleurotus geesteranus trehalose synthase gene PmTPS which is PmTPS1 and PmTPS2, the nucleotide sequence of the PmTPS1 is as shown in SEQ ID NO.1, and the nucleotide sequence of the PmTPS2 is as shown in SEQ ID NO.2. The invention further discloses a preparation method of the papaya Pleurotus geesteranus trehalose synthase gene PmTPS. According to the dsRNA of the gene PmTPS, the dsRNA is PmTPS 1-dsRNA and PmTPS 2-dsRNA, the nucleotide sequence of the PmTPS 1-dsRNA is as shown in SEQ ID NO.3, and the nucleotide sequence of the PmTPS 2-dsRNA is as shown in SEQ ID NO.4. The dsRNA of the gene PmTPS comprises the dsRNA of the gene PmTPS, the dsRNA of the gene PmTPS and the dsRNA of the gene PmTPS. The dsRNA is used for inhibiting the expression of the papaya Pleurotus geesteranus trehalose synthase gene PmTPS, so that the papaya Pleurotus geesteranus is prevented and treated.
