Abstract: A nucleotide sequence is shown in SEQ ID NO.1. The gene encodes mannosyltransferase I. The gene plays an important role in the normal reproductive development of the Nilaparvata lugens (Stål). Inhibition of the function of the gene may reduce the survival rate of the Nilaparvata lugens (Stål) and hinder embryonic development. With respect to reduction of the survival rate of the Nilaparvata lugens (Stål) and hindering of embryonic development, the present invention can reduce the harm of the Nilaparvata lugens (Stål) to rice by killing the Nilaparvata lugens (Stål). By using the characteristic that the nucleotide sequence of a highly conserved target gene has no homology with the nucleotide sequence of natural enemies of the Nilaparvata lugens (Stål), RNA interference is performed at a nucleic acid level, to avoid the harm to non-target organisms such as natural enemies, thereby realizing green control of the Nilaparvata lugens (Stål) while controlling pests.

Abstract: A constant temperature air circulation system is provided. Air valves are installed behind two three-way nodes of a main circulation loop and parallel bypasses to adjust a flowing amount of gas of each branch. When a compressor keeps a current state unchanged, a draught fan and air valves do not change. When the compressor needs to be turned on and then to be turned off, an air volume of the draught fan is adjusted, and the flowing amounts of the bypasses and a main circuit are simultaneously adjusted until the air valves that control a flowing amount of an evaporator are all closed and the air valves of the bypasses are all opened. Adjustment of the air valves and state switching of the compressor are made at the same time, so that the flowing amount flowing through a heater to a chamber is ensured to always remain unchanged.
