The invention is applicable to the technical field of microorganisms, and provides a beauveria bassiana bh002 strain as well as a screening and separating method and application thereof. The strain is classified and named as Beauveria bassiana, and is preserved in China General Microbiological Culture Collection Center (CGMCC) on May 12, 2025, and the preservation number is CGMCC No.42004. The invention further discloses a preparation method of the Beauveria bassiana strain. The corrected death rate of the strain to larvae reaches 60.26%, larva bodies begin to rigidify within 48 hours after being inoculated, hyphae completely cover the surfaces of the larva bodies in 4-8 days, and it is proved that the strain can rapidly and efficiently infect target pests. Compared with chemical pesticides, the biological prevention and control scheme has the remarkable ecological advantages that no chemical residues exist, natural enemy organisms are not damaged, the strains can continuously play a role through natural circulation, and sustainable prevention and control support is provided for a hazel forest ecological system.

Method of designing and building a floating structure with natural period of 2 seconds or above, wherein the method comprises: to provide a rigid beam model with increased stiffness, in which natural periods are greatly reduced, by extracting excitation forces, added mass and dampings via a panel model for a plurality of bodies or elements, into which the floating structure has been divided, to provide a flexible beam model with exact stiffness, by extracting excitation forces, added mass and dampings via said panel model for said plurality of bodies, whereby dynamic resonance at natural periods is captured in time domain from the beam model, to find the dynamic amplification factor by dividing the flexible beam model results on the rigid beam model results, thereby quantifying the dynamic impact and obtaining dynamic amplification factors, distinguished in that the method of designing and building a floating structure with natural period of 2 seconds or above comprises: to add the dynamic contribution to the rigid beam model excitation forces, quantified by dynamic amplification factors for the bodies, thereby finding combined forces for the bodies, to model fatigue damages, using the combined forces, to finalize the designing process, to implement the design in building models, and to build the structure on a feasible construction yard, or parts thereof on several feasible construction yards and transport and assemble said parts to the structure, wherein the resulting structure is a relatively slender structure compared to earlier method structures designed and built according to accepted codes and regulations.
