The invention belongs to the field of chemical ecology of agricultural pests and pesticide science, and relates to an insecticide composition for improving the sensitivity of agricultural pests to insecticides and application of the insecticide composition. Folic acid is applied to a pest feeding substrate, a host plant or a feed, so that the sensitivity of pests to various insecticides (including neonicotinoids, pyrimidines, pyrethroids, organophosphorus and the like) can be remarkably enhanced. It is found that folic acid can regulate and control a carbon metabolism network in pests and inhibit cytochrome P450 and other detoxification enzyme related pathways, and then the endurance capacity of the pests to insecticides is reduced. The composition and the method are verified in seven important pests such as brown planthopper, sogatella furcifera, spodoptera frugiperda, cotton aphid, chilo suppressalis, panonychus citri and thrips, have the advantages of improving the pesticide effect, reducing the pesticide application amount and delaying the resistance evolution, and can be widely applied to comprehensive treatment of agricultural pests.

This invention belongs to the field of agricultural nanoparticle formulations and green pest control technology, specifically relating to an insecticide nano-synergist Cu-TA, its preparation method, and its application. The Cu-TA consists of nanoparticles formed by the coordination assembly of copper ions and tannic acid. The Cu-TA can be used in combination with various insecticides to increase the sensitivity of brown planthoppers, white-backed planthoppers, cotton aphids, rice stem borers, and common thrips to pesticides, and to improve the field control effect on brown planthoppers. Furthermore, the combined use of Cu-TA and acetamiprid can reduce the actual heritability of resistance to acetamiprid in brown planthoppers, thereby delaying the development of resistance.

This application discloses an indoor artificial rearing method for the rice stem borer, belonging to the field of insect rearing technology. This method addresses the problems of drowning in young larvae and frequent disease outbreaks in older larvae caused by homogeneous rearing across all generations. It constructs a constant-temperature environment and prepares granular dry feed for young larvae and slightly dehydrated flake feed for older larvae based on differences in larval mouthparts. A heterogeneous three-dimensional rearing device is used. In the young larvae stage, a slow-release substrate at the bottom maintains a vertical humidity gradient, and layered feeding prevents mechanical damage to the larvae. In the older larvae stage, substrate-free bare-bottom rearing and full-volume replacement feeding are employed. Timely removal of filamentous netting blocks the breeding environment for soft rot. Furthermore, the method combines pupation induction with corrugated paper induction and non-contact moisturizing, humidification during the adult dark period to delay gelatinous hardening, and overall substrate replacement during the light period to achieve damage-free egg mass harvesting. This application, through precise age-based management, significantly improves the survival rate and population propagation efficiency of the rice stem borer across all generations.

This invention discloses the application of interfering with the expression of the conserved lepidopteran gene LSCG6 in the control of lepidopteran pests. The study found that interfering with LSCG6 in the early stages of silkworm egg development significantly reduces the egg turning rate and affects hatching. Feeding Asian corn borer larvae with LSCG6 dsRNA during their larval stage affects their development, with a 24-hour mortality rate exceeding 90%. Feeding rice stem borer larvae with LSCG6 dsRNA also affects their development, with a 24-hour mortality rate exceeding 40%. The LSCG6 gene of this invention, substances that promote the degradation of the gene transcript, substances that inhibit the synthesis of the gene transcript, or techniques that disrupt the expression of the gene can all be used for the control of lepidopteran pests. This invention provides a new target for the control of lepidopteran pests and provides a theoretical basis for the subsequent development of insecticides targeting this gene.

This invention discloses a rice-wheat rotation farmland ecosystem based on an intercropping natural enemy conservation zone of Angelica sinensis and Osmanthus fragrans, and a cross-seasonal pest control method. The method involves planting Osmanthus fragrans trees at 3-5 meter intervals along field ridges, with Angelica sinensis interspersed among them, thus constructing a perennial natural enemy conservation zone. During the flowering periods of Angelica sinensis (May-June) and Osmanthus fragrans (September-October), volatile compounds are released, providing nectar and pollen to attract natural enemies such as ladybugs, lacewings, hoverflies, and parasitic wasps to colonize and proliferate. These natural enemy populations naturally migrate into the farmland during the wheat and rice seasons to control pests such as wheat aphids, rice planthoppers, and rice stem borers, with significant control effects and reducing pesticide application by 1-2 times. This perennial system is easy to manage and can generate economic benefits from the harvest of Angelica sinensis and Osmanthus fragrans, providing a technical approach for green agriculture in rice-wheat rotation areas.

This application provides a detection primer, method, and application for the Y4667D / C mutation of the nicotine receptor in the rice stem borer, belonging to the field of agricultural pest resistance detection technology. The detection primer set is designed for the Y4667D / C mutation site, a target receptor for the rice stem borer's high resistance to diamide insecticides. It includes a first primer set for simultaneous detection of Y4667D and Y4667C, a second primer set for genotypic specific detection of Y4667D, and a third primer set for genotypic specific detection of Y4667C; each primer set contains 6-8 primers (outer, inner, and loop primers). The detection method primarily relies on visual interpretation of genotypes through color changes in the reaction solution, eliminating the need for a thermal cycler. It offers advantages such as multiple tests per tube, flexible splitting, and high sensitivity. This invention is suitable for rapid field detection of mutant genotypes and frequencies in the rice stem borer, providing technical support for diamide insecticide resistance monitoring and scientific management.

This invention relates to a detection device and method for overwintering and pupating rice stem borers. The detection device includes a box, a box cover, a rice stem borer cultivation mechanism, a rice stem borer growth monitoring mechanism, and a fixing mechanism. Different overwintering rice stem borer species are placed into corresponding rice plants and covered with porous plastic bags. The sound vibrations caused by the rice stem borers feeding and touching the rice plants and plastic bags are used by the rice stem borer growth monitoring mechanism to determine their growth stage. In conjunction with an environmental noise identification device and an environmental noise treatment device, the influence of external noise on the detection is minimized. A two-level early warning system is also included. The device infers the state of rice stem borers in the external field based on the environmental system within it. This allows for rapid assessment of the actual situation in the rice field through simple operation, and has significant practical implications.
