The invention discloses a monitoring raising pipe for tea lesser leafhoppers and a use method. The invention has the advantages that the tea lesser leafhoppers are raised and observed on tea buds of a living tea tree by a self-made monitoring raising pipe, so that the survival rate of the leafhoppers is greatly increased, and simultaneously the workload of raising is reduced; due to existence of the monitoring raising pipe, the damaging range of the tea lesser leafhoppers on the living tea tree is limited and the utilization rate of the tea tree is increased to a great extent; and the invention is simple and easy and is very suitable for raising and relevant study of the tea lesser leafhoppers for the scientific research purpose.

The invention provides a bait trap method for egg laying of lepidopteran insects, which belongs to the field of pest control technology and solves the problems of high cost, low effect, troublesome method and the like for trapping and killing insects in the prior art. The method fills plant organs and tissues as well as compositions thereof in a soft bag structure to make an insect egg-laying collector, and hangs the collector in the field to trap insets to lay eggs, thereby obtaining a large quantity of eggs. Thus, the method obviously reduces the number of pest eggs on the plants and the degree of the damage to the plants. The method can also be used in scientific research to obtain a considerable number of eggs on regular dates for raising insets. The method has the characteristics of high efficiency, simpleness, economy, environmental protection, high safety and the like.

The invention discloses a curculio chinensis chevrolat attractant and an attractant attraction core making method. The attractant is composed of at least five of six substances including cis-3-hexene-1-alcohol, cis-2-hexenyl acetate, 3-heptanone, hexanal, nonanal and hexadecanoic acid according to a volume ratio of 0-10:0-40:0-10:0-20:0-30:0-40.The making method includes: dripping a dichloromethane solution containing the attractant into a latex plug, and naturally volatilizing to obtain the attractant, wherein the attractant can be volatilized and released slowly and stably. The attractant isnontoxic, harmless and free of environment pollution and has good attraction effect on curculio chinensis chevrolat.

The invention belongs to the technical field of galleria mellonella larva inducer preparation, and particularly discloses a galleria mellonella larva inducer and a preparation method thereof. The inducer comprises an ester raw material, a saccharide raw material, a protein raw material and other raw materials; the other raw materials comprise wax residues, plastic or bran; and the inducer comprises, in parts by weight, 30-90 parts of the ester raw material, 30-80 parts of the saccharide raw material, 50-100 parts of the protein raw material and 0.01-40 part of other raw materials. The induceris mainly used for inducing the galleria mellonella larva, and solves the problems that inducers in the prior art are long in inducing time to improve the breeding cost and reduce the income for breeders.

The present application discloses a nucleic acid sequence comprising one or more selected from the group consisting of sequences SEQ ID NO: 1-7 and complementary sequences thereof, said nucleic acid sequence being derived from a plant, seed or cell comprising the corn event LW2-2, a representative sample of the seed comprising said event having been preserved with preservation number CCTCC NO: P202022; the invention further discloses a detection method for detecting the LW2-2 event. The transgenic maize event LW2-2 has good tolerance to glyphosate herbicide and glufosinate-ammonium herbicide, and the detection method can accurately and rapidly identify whether a biological sample contains the plant material of the transgenic maize event LW2-2.

The invention provides a brown algae extract. The extract is added in the expanding propagation culture process of aquaculture bait microalgae and used for inhibiting, preventing and controlling mixotrophism-type toxic dinoflagellate highly-toxic karlodinum which frequently occurs to increase the probability of successful expanding propagation of the bait microalgae, reduce harm to culture organisms, lower risks such as food chain transfer of algal toxin, and achieve health culture. By means of the brown algae extract, the multiplication of the toxic dinoflagellate highly-toxic karlodinum which frequently occurs in the expanding propagation process of the bait microalgae or marine product economical microalgae can be effectively inhibited while normal multiplication of the bait microalgaeis not influenced, the success probability of expanding propagation of the bait microalgae is increased, invasion of harmful dinoflagellate is prevented, the harm to the culture organisms is reduced,and the risk of food chain transfer of the algal toxin is lowered.
