Abstract
Description
Technical Field
[0001] The invention relates to the field of insect research, in particular to a tobacco slow-release attractant stick and an attracting method specially used as an attractant for tobacco borer larvae. Background Art
[0002] Tobacco is a stored commodity with high economic value. The tobacco borer, Ephestia elutella (Hübner), a member of the Lepidoptera family Pyralidae, also known as the tobacco powdery moth, tobacco stem borer, and cocoa moth, is a significant pest in tobacco storage.
[0003] The tobacco borer is a large insect, and its larvae often damage soybeans, wheat, flour, peanuts, cocoa beans, and chili peppers during storage. They prefer medium- to high-grade tobacco leaves that are high in sugar and low in nicotine. After hatching, the first-instar larvae feed on the soft flesh along the main veins of the leaves, leaving only the epidermis. By the second instar, they have eaten holes in the leaves, and in severe cases, they can consume the entire leaf. After feeding, the larvae spin silk to form nests of tobacco leaf debris, where they hide most often in the wrinkled areas of the leaves. According to a survey in Hubei Province, the losses caused by this insect account for approximately 1% to 2% of the total output value, causing significant losses to the tobacco industry.
[0004] Food attractants are a common method for trapping pests by exploiting their attraction to volatile semiochemicals. These attractants are gaining increasing attention in production due to their readily available raw materials, lack of harm to natural enemies, resistance to pesticides, long-lasting effectiveness, and wide spectrum of insect attraction. Timely monitoring of pest infestations in tobacco leaves and other stored items during storage is crucial for effective and scientific pest control. However, current methods for monitoring tobacco borers primarily utilize sex pheromones as attractants, a method that only captures adult male borers. Research on attractants for tobacco borer larvae has been reported in China and abroad. Summary of the Invention

[0021] Example 1: In conjunction with all accompanying drawings; A tobacco borer larvae attractant characterized by comprising corn flavor, linoleic acid, oleic acid, grapeseed oil, and rapeseed oil; the volume ratio of corn flavor, linoleic acid, oleic acid, grapeseed oil, and rapeseed oil being 8:64:4:8:16 or 21.6:43.2:10.8:2.7:21.6. The substantial technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: corn flavor, linoleic acid, oleic acid, grapeseed oil, and rapeseed oil are uniformly mixed in a ratio of 8:64:4:8:16 or 21.6:43.2:10.8:2.7:21.6 to form a food attractant for tobacco borer larvae, facilitating their entry. The trap is then placed in a stored cigarette stack or other stored item, achieving a good attractant effect. Laboratory measurements have shown that the behavioral selection coefficient for tobacco borer larvae can reach over 50%. Advantages: The raw materials of food attractants are easy to obtain, the attracting effect is good, and it is easy to use. It can efficiently and timely monitor the occurrence of tobacco borer larvae and provide technical support for scientific guidance of comprehensive prevention and control of tobacco borer.
[0022] The "trap" two-way choice method was used to determine the behavioral choice of tobacco borer larvae towards odor sources. Figure 1 ) Place 2 mL of liquid odor source in one tube, and leave the other tube empty as a blank control. Then, release 20 tobacco stem borer larvae into the center of the experimental apparatus and quickly close the lid. The trap was placed upright in a plastic basin with a bottom diameter of 52.5 cm. Cover the basin with tin foil. Keep the experiment in darkness, maintain a temperature of (28 ± 2°C) and a relative humidity of (60 ± 5%). After 48 hours, observe and record the number of test insects in the two plastic tubes, and calculate the behavioral selection coefficients of tobacco stem borer larvae for different odor sources. Repeat three times.
[0023] Behavior selection coefficient = (A-B) / (A+B) × 100% A: Number of insects attracted by the odor source in the experimental group B: Number of insects attracted by the odor source in the control group If the behavioral selection coefficient is greater than 0, it means that the odor source is attractive to the test insects. The larger the value, the stronger the attraction, and the maximum value is 1. If the behavioral selection coefficient is less than 0, it means that the odor source is repellent to the test insects. The larger the absolute value, the stronger the repellency, and the maximum value is 1.
[0024] Evenly mix corn essence, linoleic acid, oleic acid, grape seed oil and rapeseed oil in the ratio of 8:64:4:8:16 (odor source 1) or 21.6:43.2:10.8:2.7:21.6 (odor source 2) to make food attractant for tobacco borer larvae.
[0025] Table 1 Behavioral selection coefficients of tobacco borer larvae to different odor sources Larvae name Food attractant dose / µL Insect attraction rate / % Odor Source 1 25 37.5±12.0b 50 50.0±12.0a 100 51.0±18.6a Odor Source 2 25 69.0±6.01a 50 70.0±14.8a 100 71.0±18.6a There are currently no commercially available attractants for the larvae of tobacco borer and other stored product pests.

The substantial technical effect and implementation process of this technical solution, i.e., the basic function, are as follows: the inclined hole prevents tobacco stem borer larvae from crawling out.
[0033] Example 8: As a further improved solution, a parallel solution, or an optional independent solution, multiple sets of insect collection rings 7 arranged in parallel above and below are each numbered, with each number corresponding to a scale.
