Two or more conditional, dominant, lethal gene expression systems provide high levels of penetrance in insects. Lethality is induced at an earlier stage of development and the risk of biochemical resistance is reduced, as compared to a single insect conditional, dominant, lethal gene expression system. The invention is useful for the control of insect populations.

A management and distribution device for insect breeding includes a main body, an upper cover, and a lower cover. The upper cover is clamped to a top portion of the main body, and the lower cover is clamped to a lower end of the main body. Three partition plates for insects to climb are clamped in an inner portion of the main body, and the three partition plates are wave-shaped. A notch is defined at a lower middle portion of each of the three partition plates, a plurality of through holes for insect faeces to pass through are defined on a bottom of the main body, an insertion opening is defined at a lower end of an outer wall of the main body, and a hinge door is rotatably disposed at the lower end of the outer wall of the main body.

This invention relates to an improved system for releasing beneficial mites and the use of such a system. Mite species that can be used beneficially for human purposes may for example be employed in the control of pests, such as in the field of agriculture, including agricultural production systems for plant products, agricultural production systems for animal products, and animal husbandry, or in the field of storage of food products. The system of the invention may find use in any of these fields.

The present invention pertains to a silkworm-type biotinylated CTLD14 or sRAGE and a method for manufacturing the same. One embodiment of the present invention provides a method for manufacturing biotinylated proteins, wherein the method includes A) a step for inserting a nucleic acid molecule for coding biotin ligase and protein in a coexpressable manner into a silkworm or a living organism that imparts sugar chains that are the same as the sugar chains of the silkworm, B) a step for causing the biotin ligase and protein to be expressed by disposing the silkworm or the living organism that imparts sugar chains that are the same as the sugar chains of the silkworm to conditions with which the nucleic acid molecule will carry out expression, and C) a step for administering biotin to the living organism and obtaining the biotinylated protein.

A continuous feeding device for predatory mites, including a feeding part and an isolation part to solve problems existing in the prior art of accurately controlling a feeding quantity of predatory mites, and reducing a number of the feeding devices required for feeding predatory mites, thereby reducing a feeding cost of predatory mites.

The present disclosure provides compositions with a modulating gene expression and methods for modulating transcription.

A mobile culture assembly for feeding larvae of black soldier fly includes a mobile vehicle, a breeding device disposed in the mobile vehicle, and a turning device disposed on the breeding device. The breeding device includes spaced-apart breeding bodies, each of which defines a breeding space for accommodating feed materials and larvae. The turning device includes a base movably disposed on the breeding body, a feeding unit adapted to introduce the feed materials to the breeding space, a turning unit disposed under the base, a scrapping unit disposed at one end of the base, and a heat dissipating unit disposed on the base. The turning device serves to stir the feed materials and the larvae and also dissipate heat accumulated in the breeding space to thereby provide a preferable growing environment for the larvae, reduce feeding costs, and increase a reproductive rate and quality of the larvae effectively.

The present invention relates to a method and facility for breeding insects. According to the invention, the insect breeding facility comprises a spawning area comprising spawning containers which are adapted to receive adult insects and insect food, wherein at least one spawn structure is provided in each spawning container, in which spawn structures the mother insects will spawn their eggs. Furthermore a hatch area is provided in which the eggs will hatch and which allows periodical harvesting of baby larvae from the hatch area. The hatch area comprises a plurality of hatching chambers corresponding in number with the number of batches of spawning containers.

The present invention relates to:—on one hand, a beetle powder including a percentage by weight of vitamin D3 greater than or equal to at least 0.00001% and a percentage by weight of calcium greater than or equal to at least 0.1%, the percentages by weight being given on the total weight of beetle powder, and—on the other, a method for rearing beetles for preparing such a powder, which includes a light treatment phase during which a UV source emits ultraviolet rays towards the beetles.

A system for controlling population of a biological species includes a population of genetically-modified individuals of the biological species, where both males and females in the genetically-modified population carry two mutations. The first mutation is a repressible genetic mutation that results in death of a juvenile individual of the first sex when the juvenile individual of the first sex comprises the repressible lethal mutation and is reared in the absence of a repressor or causes an individual to be sterile when reared in the absence of a repressor. The second mutation is an underdominant genetic mutation.
