The invention relates to the technical field of biological prevention and control of pests, in particular to a breeding method of natural enemy insects, and particularly relates to a prevention and control method of a bee colony juvenile beauty disease, which comprises the following steps: filling a mixed solution of a cinnamon leaf aqueous solution and an oxytetracycline aqueous solution into a sprayer, and spraying to a sick bee colony until the body surfaces of larvae are wet without dripping water. According to the scheme, the mixed solution of the cinnamon leaves and the oxytetracycline has a good prevention and treatment effect on the meloidosis of the wasp colony, the loss caused by diseases to the wasp colony can be greatly retrieved, the success rate of the primary wasp colony can be greatly increased, and the mixed solution has small side effects on wasps and is low in cost.

This invention relates to the field of artificial breeding technology for natural enemy insects, and in particular to a method for the artificial breeding of the assassin bug *Triplophysa pulcherrima*. The invention employs steps including seed source collection and screening, rearing environment control, feed supply and management, mating and reproduction management, oviposition and egg mass collection, nymph hatching and age-differentiated rearing, overwintering management, and cannibalism control. By providing specialized rearing management devices, temperature and humidity conditions, standardized feed feeding, age-differentiated rearing density control, and moisture-controlled egg mass hatching, it solves the problems of high mortality rates among young nymphs, unstable mating success rates, low egg mass hatching rates, and the lack of a year-round breeding system in existing technologies. The method of this invention is simple to operate, has a high survival rate (nymphal survival rate exceeding 85%), an egg mass hatching rate exceeding 90%, and can achieve 4-5 generations per year, enabling large-scale, year-round production of *Triplophysa pulcherrima*, providing high-quality natural enemy resources for the biological control of agricultural and forestry pests.

The utility model provides a biological prevention and control device for stored insect pests, which belongs to the technical field of biological prevention and control and comprises a bin shell, a fixing groove formed in the side wall of the bin shell, an insect repelling block clamped in the center of the fixing groove and a dismounting component arranged on the inner wall of the insect repelling block. The multiple fixing grooves are formed, and the multiple insect repelling blocks correspond to the multiple fixing grooves. According to the utility model, through the matched layout of the plurality of detachable insect expelling blocks and the fixing grooves, the device can flexibly adjust the prevention and control point positions according to the storage space; the innovative dismounting assembly adopts a spring clamping block mechanism, so that one-key type quick replacement of the insect expelling block is realized, and the maintenance difficulty is greatly reduced; double locking of the elastic block and the clamping groove ensures installation stability, and looseness caused by long-term use is avoided; the operation component is linked with the pull rod through the bearing seat, so that the replacement process is labor-saving and convenient; the whole structure is good in sealing performance, volatilization of insect repelling components is effectively delayed, and the technical problems that a traditional device is fixed in layout, difficult to maintain, poor in sealing performance and the like are solved.

The present invention relates to a novel bacterium Pseudomonas sp. 14og as deposited into the NRRL Patent Culture Collection on 3 Dec. 2020 and designated NRRL accession no. B-67999. The present invention also relates to insecticidally active substances obtained or derived from Pseudomonas sp. 14og. The insecticidal substances find use in controlling, inhibiting growth or killing Lepidopteran, Coleopteran, Dipteran, Hemipteran, Tetranychidae, fungal, nematode and mite pest populations and for producing compositions with insecticidal activity. The present invention relates to a novel bacterium and use for biocontrol of insect pests. More particularly, the invention relates to a newly discovered species of Pseudomonas bacterium that exhibits insecticidal activity. The invention also relates to proteins and / or peptides and / or metabolites obtained from the strain that possess insecticidal activity and to insecticidal compositions comprising cultures of the novel strain and / or supernatants, filtrates, and extracts obtained from the strain, and use thereof to control insect pests. The present invention relates to a novel bacterium and uses thereof. In particular, the present invention relates to applications concerned with the biopesticidal activity of the novel bacterium and of its mutant or variant strains. The present invention also concerns proteinaceous substances produced by this novel bacterium and of its mutant or variant strains obtained or derived from the aforesaid bacteria.
