(II) when the Spodoptera frugiperda larvae grow to 3 years and need to be raised with one head, turning over the raising device to enable the bottom cover 300 to be positioned at the upper position, opening the third lock catch 120 and the fourth lock catch 320, detaching the bottom cover 300 from the box body 100, placing the barrier 500 shown in the figure 5 into the box body 100 from the lower opening of the box body 100, enabling the barrier 500 to divide the box body 100 into 2 rows and 5 columns of compartments corresponding to the window 201, placing the old larvae into the compartments and putting in food, covering the bottom cover 300 on the lower opening of the box body 100, and locking the third lock catch 120 and the fourth lock catch 320. The compartment is used as a separate breeding room for the old larvae, thereby avoiding the self-killing of the old larvae and improving the breeding efficiency.
Opening the window lid 210 that the compartment corresponds alone can observe, feed, clear up rubbish at the compartment that corresponds, also can pull down top cap 200, raise the larva in whole box body 100 through the upper shed of box body 100, can also overturn box body 100, pull down bottom 300, raise the larva in whole box body 100 through the lower open-ended of box body 100.
Meanwhile, the inside humidity of the box body 100 is adjusted through the leftward and rightward sliding of the air hole air adjusting plate 400, so that the larval excrement is in a relatively dry state, the old larval can use the dry excrement in the compartment to make a pupation chamber, pupation is directly performed in the compartment, and the tedious steps of transferring the old larval to a breeding box filled with soil or fine sand and the like for pupation are reduced.
And (III) before the pupae emerge, turning the breeding device again to enable the top cover 200 to be positioned at the upper position, and the pupae develop to emerge in the compartment. The window cover 210 is slightly opened when the adult insects are in a resting state in the photoperiod, and the sex is distinguished through the characteristics of the front wings of the adult insects, so that the inconvenience that the pupa chamber is damaged to observe the characteristics of the 8 th and 9 th abdominal knots of the pupa to distinguish in the past in the later period of the pupal period is avoided, and meanwhile, the injury to the pupa is avoided. The window covers 210 corresponding to the compartments are independent from each other, and can be independently opened when a large amount of pupae emerge, so that the influence on other individuals is reduced when adults are observed and caught, and the adults are prevented from escaping after being stimulated. After the sex is distinguished, the imagoes can be captured and transferred to another imago breeding device for breeding when the imagoes are bred in pairs.
The breeding device can meet the breeding requirements of low-age larvae and high-age larvae, is rich in use and reduces cost, and the top cover 200 or the bottom cover 300 can be disassembled, so that the whole device can be cleaned more efficiently and conveniently.
In this embodiment, the bottom cover 300 is detachably mounted to the lower opening of the case 100. But not limited to this embodiment, the top cover 200 may be detachably mounted to the upper opening of the case 100; or/and, the bottom cover 300 is detachably mounted to the lower opening of the case 100, and the partition can be inserted or removed by opening the top cover 200 or the bottom cover 300. Specifically, when the top cover 200 is detachably mounted on the upper opening of the box 100, the grid 500 can be put into the box 100 from the upper opening of the box 100 to divide the box 100 into 2 rows and 5 columns; when the bottom cover 300 is detachably mounted on the lower opening of the box 100, the barrier 500 can be put into the box 100 from the lower opening of the box 100 to divide the box 100 into 2 rows and 5 columns; alternatively, the top cover 200 and the bottom cover 300 are detachably mounted to the case 100, and the grill 500 may be arbitrarily inserted into the case 100 from the upper opening or the lower opening of the case 100.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
