This application discloses a Penicillium strain with stress resistance, growth promotion, and insecticidal functions, and its applications. The preservation number of this Penicillium strain is CGMCC No. 42545. This Penicillium strain naturally integrates four functions: salt tolerance, drought tolerance, plant growth promotion, and insecticidal activity against lepidopteran pests. It can grow normally in a 15% NaCl concentration medium, significantly improving plant survival rate under drought stress. Simultaneously, it promotes growth indicators such as root length and root fresh weight in crops like peas. It exhibits highly effective lethal activity against young larvae of lepidopteran pests such as diamondback moth and beet armyworm, and has high safety against non-target organisms. This Penicillium strain can be prepared into solid or liquid inoculants, showing promising application prospects in stress resistance, growth promotion, and pest control for crops grown in saline-alkali / arid areas. It realizes an integrated solution of "stress adaptation - crop growth promotion - pest control," replacing the combined use of multiple single-function agents and reducing agricultural production costs.

The inventors found in a sage, Salvia pisidica Boiss. & Heldr. substances that can kill Borrelia spp. and Yersinia spp. in vitro and in vivo. Up to now, it has been assumed that a methanol extract or the oil of Silvia pisidica has antimicrobial effects against gram (+) bacteria. Previous experiments confirm this current scientific view.

An RNA interference method for controlling insect pests by inhibiting translation of messenger RNA (mRNA) of target genes in the insect's cholinergic system. The method includes preparing double-stranded RNA (dsRNA) or single-stranded antisense oligonucleotides specific to target mRNAs encoding nicotinic acetylcholine receptor subunits or auxiliary proteins, and administering an effective amount to induce mortality or increase sensitivity to insecticides. The target mRNAs include neuronal α and β subunits of nicotinic receptors and auxiliary proteins such as RIC-3, Lynx, NACHO, and UNC-50. Administration may be topical, oral, or through transgenic plants expressing the interfering RNA. The method is particularly effective against agricultural pests like Acyrthosiphon pisum and can restore sensitivity in insecticide-resistant insects. Compositions including the interfering RNA with transfection agents or solvents are provided, along with transgenic plants expressing the interfering RNA.
