Description

insecticidal composition containing gossypol The present invention relates to a technology for controlling rice pests and diseases, and more specifically to a chemical agent for controlling a type of rice lepidopteran pest. Gossypol, also known as cotton toxin, is a polyphenolic hydroxybinafthylaldehyde compound formed within the bodies of cotton plants of the Malvaceae family and stored in the pigment glands. It is a yellow polyphenol substance present in various organs of the cotton plant. Gossypol can have a significant impact on the survival, reproduction, and population growth of pests. Feeding cotton moth larvae with feed high in gossypol adversely affects important life variables such as body weight, developmental period, survival rate, pupal rate, emergence rate, mating rate, egg laying, and hatching rate, thereby exhibiting insecticidal properties. Chlorantraniliprole is a broad-spectrum insecticide with a novel structure selected from bisamide compounds. Its mechanism of action involves activating nicotine receptors in the muscles of pests, thereby inducing an excessive release of internal calcium ions. Consequently, the pests stop feeding, leading to muscle paralysis, loss of vitality, paralysis, and even complete death. Since entering the Chinese pesticide market in 2010, chlorantraniliprole has been widely used to control various agricultural and forestry pests. It has excellent control effects against lepidopteran pests such as the Noctuidae, Pterocarydae, Codworms, Leafrollers, Whiteflies, Diamondback Moths, Grain Moths, and Slender Moths, and can further control various non-lepidopteran pests such as the Weevils and Chrysomelidae of Coleoptera; and the Leafminers and Whiteflies of Diptera. Currently, if registered as a major pest control target for rice, it can rapidly protect rice growth and is particularly effective against pests that have already developed resistance to other rice insecticides, such as the rice leafroller, rice stem borer, rice stem borer, and rice armyworm. It also provides good control effects against Orseoia oryzae , rice weevils, and rice water weevils. Due to the long-term use of chlorantraniliprol, lepidopteran pests in many areas of rice have already developed varying levels of resistance, making it impossible to achieve the expected control effects of the pesticide. Therefore, a method must be found to effectively delay the development of resistance. The present invention is described further below with reference to examples, but the present invention is not limited by the following examples. Example 1 Indoor toxicity of chlorantraniliprol and gossypol on rice stem borers Egg masses were collected in Yutai County, Jining City, and reared in the laboratory until hatching; after rearing, the egg masses were fed artificial feed for up to 3 years, and toxicity detection tests were performed using the artificial feed film method: A mother liquor of chlorantraniliprol at a specific concentration was prepared using dimethylformamide (DMF) and diluted with Triton-100 solution (0.1 wt%) to obtain five series of treatment solutions according to a gradient. A mother liquor of gossypol acetate was prepared by dissolving it in acetone and diluted with Triton-100 solution (0.1 wt%) to obtain five series of treatment solutions according to a gradient; a mixture of chlorantraniliprol and gossypol acetate was prepared by the following method: gossypol acetate was added during the preparation of a series of concentrated solutions of chlorantraniliprol, with mass ratios of the two being 1000:1, 500:1, 200:1, 100:1, and 50:1, and the concentration of chlorantraniliprol in the mixture matched the concentration of a single dose; The preparation of artificial feed was based on the method of Liu Huimin and Han et al. After preparation was complete, an appropriate amount of artificial feed was placed into a 24-well plate while hot. After the feed condensed, the feed surface was smooth, free of air bubbles, and there were no gaps between the feed and the pore walls, while avoiding any residue of feed remaining in the pores and on the pore walls. A certain amount of liquid was absorbed according to the concentration of the agent, in order from lowest to highest, and added to the 24-well plate containing the artificial feed. Natural air drying was performed using Triton-100 solution (0.1 wt%), which represents the highest DMF concentration in the chlorantraniliprol solution, at a dose of 100 μL per well, as a control. Twenty larvae were treated for each case, and the process was repeated three times. After treatment, the specimens were placed in an artificial climate box with a relative temperature of 26 ± 1 °C, relative humidity of 60%–80%, and a photoperiod of L:D = 14:10, and the number of dead insects was checked for 72 hours after treatment. Using SPSS data processing software, the toxicity regression equation, R² , LC50 , and 95% confidence limits were established, and the reinforcemen
