Problems solved by technology

[0006] The technical problem to be solved by the present invention: Most of the current attractants have a single species of attracting insects, fast release, and the attractant cannot be fully and effectively used. Uneven release will cause poor attractant effect, and may even be caused by excessive concentration of the attractant. High and have the problem of avoiding pests, the present invention first soaks the rice and then adds α-amylase preparation and lactose to cultivate, adds sodium alginate to the culture medium to obtain viscous liquid, and then heats and presses the rice husk treatment to make the rice husk expand and soften, dry and pulverize to obtain the processed rice husk powder, add 1-octen-3-ol, valeraldehyde, maltol and vanillol to dilute and dissolve with carbon tetrachloride respectively, and obtain the lure Mix the attractant liquid, the treated rice husk powder and the standby viscous liquid to prepare the slow-release attractant for rice pests. The attractant prepared by the present invention has a long release time and uniform release, and uses rice as the slow-release base material, and adding attractant, it can have a good luring effect on various stored grain pests such as red corn beetle, rice elephant, and saw beetle, and the process is novel and the cost is low

Abstract

The invention relates to a preparation method of a paddy rice injurious insect slow-release attractant, which belongs to the technical field of injurious insect prevention and control. The preparation method comprises the following steps: firstly soaking rice, then adding an alpha-amylase preparation and lactose to perform the culture, adding sodium alginate into a culture solution to obtain a viscous solution for standby use, then heating and pressurizing rice husk, swelling and softening the rice husk, drying and crushing the rice husk to obtain processed rice husk powder, separately adding 1-octen-3-ol, pentanal, maltol and vanilla phenol into tetrachloromethane, diluting and dissolving to obtain an attractive solution, and mixing the attractive solution, the processed rice husk powder and the standby viscous solution, thus obtaining the paddy rice injurious insect slow-release attractant. The attractant prepared by the preparation method is long in release time and uniform to release; by adopting the paddy rice as a slow-release base material and adding the attractant, the attractant has good attractive effect for various stored-grain injurious insects such as tribolium castaneum, rice weevil and sawtoothed grain beetle; and the process is novel, and the cost is low.

Description

technical field [0001] The invention relates to a preparation method of a slow-release attractant for rice pests, and belongs to the technical field of pest control and preparation. Background technique [0002] In the generational development chain of agricultural and forestry pests, the adult stage is a key stage of population reproduction, which is easily affected by various environmental factors and is also a weak link that is easy to implement human ecological intervention. On the one hand, the adult stage is the stage with the strongest dispersal ability, and Feeding, courtship and oviposition mainly depend on the sense of smell. On the other hand, the choice of host for adult oviposition determines the distribution of offspring larvae, and the nutritional status determines the amount of oviposition and offspring population. [0003] Food attractant refers to the use of a certain food or a certain chemical component in the food to lure pests, which can make the pests d...
