Background Art

[0002] Leaf rollers are common pests in orchards and forests around the world. The apple leaf roller and the apple leaf roller are among the most serious leaf roller pests. Leaf rollers typically spin silk and then dart from leaves, hiding within them to cause damage. They also hide within the rolled leaves to lick or bore into the fruit, causing fruit deterioration and weakening the trees, reducing the productivity of orchards and landscaping. Chemical control is difficult, making prevention and control challenging and causing significant damage.

[0003] Leaf-rolling moth pests are difficult to control, mainly because the insects are small and hide in the leaves to cause damage. Their life cycle of pupation, emergence and egg laying is difficult to observe. When raising these pests in the laboratory, the above-mentioned breeding processes are often separated, which takes up space, is labor-intensive, time-consuming and inefficient.

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] The present invention provides a device for the emergence of leaf roller moth pupae, feeding and laying eggs for adults, comprising a box body 1 made of a transparent material and an egg-laying assembly consisting of a nutrition tube 201, a thermometer and humidity meter 202 and an egg-collecting strip 203. Figure 1 shown.

[0028] like Figure 2 , Figure 3 As shown, the enclosure 1 is a roughly rectangular parallelepiped structure, with the bottom width slightly smaller than the top. Specifically, the top is 31 cm long and 21 cm wide; the bottom is 28.6 cm long, 18.6 cm wide, and 18 cm high. The enclosure 1 is made of a transparent material, allowing observation of the pupal emergence process, adult mating, and female egg laying.

[0029] A top cover 101 is installed on the top of the box body 1. The top cover 101 is fixed with buckles 103 designed in the middle of the outer walls around the top of the box body 1 through slots 102 designed in the middle of the inner walls around the top cover 101.

[0030] A ventilation area is designed on the left and right side walls of the box 1. The ventilation area is provided with 9 0.3 cm holes 104 arranged in a square shape in 3 rows and 3 columns. The vertical distance between the ventilation area and the top surface of the box 1 is 8 cm, and the vertical distance between the ventilation area and the bottom surface of the box 1 is 4 cm. The distance between adjacent holes 104 is 3 cm, so as to realize air circulation inside the box 1 and maintain appropriate humidity and temperature inside the box 1.

[0031] The interior of the box 1 contains a pupal living area 2, an adult living area 3, and an egg-laying unit. The pupal living area 2 consists of a 3-cm-thick layer of fine sand on the bottom of the box 1, which is used to hold the pupae. To ensure the thickness of the fine sand, a sand line is engraved around the inner wall of the box 1 at a vertical height of 3 cm from the bottom of the box 1 to calibrate the thickness of the fine sand on the bottom of the box 1.

[0032] The rest of the box 1 is the adult living area 3. The leaf roller moth pupae are placed in the fine sand, develop and emerge in the fine sand, and then fly out of the sand into the adult living area 3. The adult living area 3 is a mating area for adults and is equipped with an egg-laying assembly.

[0033] In the egg-laying assembly, the nutrient tubes 201 have a diameter of 2.5 cm and a height of 2.5 cm. There are four of them, which are respectively arranged at the four corners inside the box 1. They are fitted with the walls of the box 1 at the four corners and supported by the walls of the box 1. At the same time, the bottom is buried in fine sand and fixed to increase the stability of the nutrient tubes 201.

[0034] The thermometer and hygrometer 202 is fixed at the angle where the front and right sides of the box body 1 meet, and is used to display the temperature and humidity inside the box body 1 and to observe the temperature and humidity inside the box body 1.

[0035] The egg collection strips 203 are rectangular paper strips 0.15 mm thick, 5 cm wide, and longer than the combined height of the box 1 and the thickness of the top cover 101. Ten egg collection strips 203 are inserted into the box 1 through ten egg collection slots 105 defined in the top cover 101. The ends are then inserted into the fine sand at the bottom of the box 1 and secured. The other ends extend beyond the top cover 101 and are bent to position the egg collection strips 203, preventing them from falling into the box 1.

[0036] The 10 egg collecting slots 105 provided on the top cover 101 are as follows: Figure 4 As shown. The egg-collecting strip slits 105 are 5 cm long, equal to the width of the egg-collecting strip 203. The egg-collecting strip slits 105 are 4 mm wide, greater than the thickness of the egg-collecting strip 203, to minimize contact with the slits when removing the egg-collecting strip 203 and damaging the eggs on the strip. The six egg-collecting strip slits 105 are grouped in threes; two groups of egg-collecting strip slits 105 are located near the front and back sides of the top cover 101, parallel to the front and back sides, and evenly spaced in the left-right direction. The other four egg-collecting strip slits 105 are grouped in twos; two groups of egg-collecting strip slits 105 are located near the left and right sides of the top cover 101, parallel to the left and right sides, and evenly spaced in the front-to-back direction.

[0037] The present invention integrates the adult living area 3 and the pupal living area 2 of the leaf roller moth within the same housing 1. This allows the pupae to naturally enter the adult living area after emergence, feeding from a nutrient tube to supplement their nutrition, mate in the adult area, and lay eggs on the egg-collecting strips 203. Due to the habits of adult leaf rollers, they rarely lay eggs if the inner wall of the housing 1 is too dry, and they do not lay eggs on the fine sand at the bottom of the housing 1. Therefore, most of the eggs of adult leaf rollers are concentrated on the egg-collecting strips 203. The egg-collecting strips 203 can be freely removed from or inserted into the gaps 105 of the strips. By monitoring the temperature and humidity of the housing 1, the temperature and humidity can be adjusted in a timely manner to maintain suitable environmental conditions for emergence and egg-laying. For example, a gauze can be set between the top surface of the box 1 and the top cover 101, and the humidity inside the box 1 can be increased by spraying moisturizing spray on the gauze; the gauze is tightened and fixed by the top cover 101 and the top surface of the box 1, and openings are made in the gauze at positions corresponding to the egg collecting strips 203, so that the egg collecting strips 203 can pass through the gauze. The humidity inside the box 1 can be reduced by increasing the air intake of the ventilation holes on both sides of the box 1. The temperature inside the box 1 can be increased or decreased by adjusting the external ambient temperature of the box 1. The specific application steps of the pupal emergence, adult rearing and egg laying device of the leaf roller moth of the present invention are as follows:

[0038] Step 1: Soak an appropriate amount of fine sand in water and spread it evenly on the bottom surface of the box 1, ensuring that the thickness does not exceed the sand line. Place the leaf roller moth pupa on the fine sand. A thermometer and hygrometer 202 is fixed at an angle within the box 1. Simultaneously, nutrient tubes 201 filled with nutrient solution are inserted into the fine sand at the four corners of the box 1 and fixed. A gauze mesh with egg-collecting slits 105 is laid on the top of the box 1. Cover it with a top cover 101 and clamp the mesh securely.

[0039] Step 2: Insert the egg collecting strip 203 into the gap 105 between the top cover 101 and the gauze, into the box 1, and secure the bottom end in the fine sand. Then, connect the top cover 101 and the box 1 using the buckle 103 and the slot 102, pressing and securing the gauze. After the top cover 101 is secured, bend the top of the egg collecting strip 203 beyond the top cover to longitudinally position the strip 203.

[0040] Step 3: Place the box 1 assembled in steps 1 and 2 in a suitable room with normal lighting, and observe, record and take photos regularly.
